The New Pool Owner Guide
| |

What to know before you ever talk to a builder. The decisions you make before the first meeting will determine how smoothly your entire project goes.

Pull Your Property Survey First
  • Pull your property survey before anything else — it is one of the most important documents you own
  • Setbacks and easements are measured from property lines — not your fence
  • Most Texas cities require a pool to sit at least 3 feet from any property line
  • Utility easements cannot be built upon — not the pool, not the deck, not the equipment pad
  • Drainage easements — same rule. No permanent structures allowed within them
  • If you cannot find your survey, contact your county clerk or title company

Utility easements are legally reserved for underground infrastructure — gas, electrical, cable, water, drainage. If a utility company needs to access an easement, they are not obligated to repair or replace anything they damage — including a pool built inside one. Typical rear utility easements in Texas run 7 to 14 feet along the back property line. Your fence may not be placed exactly on the property line, so never use the fence as your measurement reference.

Walk Your Backyard Before Calling Anyone
  • Lay out a garden hose in your desired pool size and shape — live with it for a few days
  • Look at it from inside the house, from the patio, and from the back of the yard
  • Decide which side of the yard you want the pool equipment on — pump, filter, heater, chiller
  • Note where your gas meter or propane tank is located
  • Note where your electrical panel is located
  • Measure your side yard access — 6 feet or more is needed to get construction equipment to the backyard
  • Know where your irrigation system runs — those lines will need to be rerouted

If your gas service is on the opposite side of the house from your intended equipment pad, running a new gas line around the structure can add thousands of dollars to your project. The same applies to electrical. A thorough builder will ask about both of these upfront. If they don’t, that is a red flag.

Critical Site Conditions Your Builder Should Raise

A knowledgeable builder will raise every one of these. If they don’t, consider it a warning sign.

  • Overhead power lines near the build zone
  • Septic tanks, drain fields, and aerobic systems — extremely common in Hill Country and rural Austin builds
  • Soil conditions — Central Texas clay soils shift with moisture and affect pool engineering
  • Large trees and root systems near the pool location (see CRZ below)
  • Existing irrigation lines running through the build zone
  • Drainage — where does water go when the pool overflows or when it rains heavily?
Septic & Aerobic Systems

A pool must maintain a minimum 5-foot setback from a septic tank and drain field. Aerobic systems are more complex — in many Texas areas the drain field cannot be within 25 feet of the pool, and aerobic sprinkler heads must be at least 50 feet from the pool. Texas regulates on-site sewage facilities under 30 TAC Chapter 285 through the TCEQ. Always confirm with your local permitting authority as local rules may be more restrictive.

Soil Conditions

Central Texas is well known for expansive clay soils that shift and move with moisture changes. This directly affects how your pool shell is engineered and may require additional structural steel. A builder who never mentions soil conditions in Central Texas hasn’t built enough pools in the region.

Trees & Critical Root Zones (CRZ)

Large live oaks and cedar trees near your pool location are a hidden cost that surprises many homeowners. The CRZ contains most of the roots vital to a tree’s health and survival. If construction invades too far into the CRZ, the tree may not recover. If 30 percent of a tree’s CRZ is impacted, it could be deemed beyond probable recovery.

How to calculate your CRZ:

Measure the trunk circumference at 4 feet above the ground. Divide by 3.14 to get the diameter in inches. Multiply the diameter by 1.5 — this gives you the CRZ radius in feet. A trunk with a 45-inch circumference has a CRZ radius of approximately 22 feet in every direction.

Most of a tree’s roots are within the top 18 inches of soil, and 85% of the root mass sits within the CRZ. Pool shell excavation, equipment pad grading, and plumbing trenches can all cause irreversible damage if they cross into this zone. Removal of significant trees may also require a permit in Austin and many Hill Country municipalities.

Permits, Fencing & HOA Requirements
Permits
  • Your builder should handle all permitting — you should not be doing this yourself
  • After the permit is filed, verify it directly with your city’s building department — don’t take anyone’s word for it
  • Confirm the permit number is active before any ground is broken
  • Unpermitted pools create serious problems at resale and can require costly retrofits or demolition
Fencing & Safety Barriers
  • Texas requires a barrier around all pools deeper than 24 inches — this is not optional
  • Fences must be at least 48 inches tall, measured from the outside of the pool area
  • Chain-link fencing is prohibited for pools built after 1994
  • No gaps may exceed 4 inches — gates must be self-closing, self-latching, and swing inward away from the pool
  • Budget for fencing early — it is part of the total project cost and a condition of final inspection
HOA
  • Many HOAs require architectural committee approval before construction begins
  • HOAs can have additional setback requirements, aesthetic standards, and fencing rules beyond city code
  • This approval process can take weeks — start it early
  • Get all HOA approval in writing before signing a pool contract
A Word on Pool Builders in Texas
  • There is no dedicated state license required to start a pool construction company in Texas
  • The barrier to entry is very low — quality varies widely across the market
  • The cheapest bid is rarely the best value
  • Incomplete projects, abandoned contracts, and poor workmanship are real and recurring problems in Texas

What IS regulated: Standard pool plumbing does not require a plumber’s license in Texas, though some cities require a licensed plumber on the permit — verify locally. Gas line work must be performed by a licensed plumber. RPZ (backflow prevention) valves must be installed by someone with a valid backflow prevention certification. Electrical work on pool equipment requires a Residential Appliance Installer License (RAIL) from TDLR. Irrigation contractors must hold a TDLR license. You can verify any TDLR license at tdlr.texas.gov.

Choosing Your Plaster — See It in Real Water
  • The small chip samples your builder hands you do not show you what your pool will look like
  • Your tanning ledge, top step, and bench will always appear significantly lighter than the deep end — same plaster, different depth — this is normal
  • Pool color is affected by your house color, surrounding trees, sky conditions, and water chemistry
  • For water that looks primarily blue, select a finish with white, blue, or gray pigment
  • For water that appears green or aqua, look for green, tan, brown, or black pigment
  • The darker your finish, the darker your pool water will be

Living Water & Plaster Colors: One of the most underappreciated elements in pool design is what happens to plaster color when the water moves. Still water shows your plaster one way. Active water — from sheers, bubblers, deck jets, or waterfalls — creates constant refraction that makes the color shift, shimmer, and dance in ways a static pool never can. The same plaster you chose from a chip sample will look entirely different, and far more beautiful, when the water is in motion. When selecting plaster colors, ask your builder to show you video or photos of that finish in pools with active water features — because that is what your pool will actually look like. See the Water Features section for more on living water design.

Where to research real plaster in real water:
  • Houzz.com — search by finish name for real installation photos
  • Pinterest.com — search pool finish color names for mood boards and real photography
  • Instagram and TikTok — search #texaspool #hillcountrypool #poolplaster for video walkthroughs in natural light
  • Facebook — search local pool owner groups for real customer photos in your area
  • Ask your builder for references with the finish you are considering — go see it in person

Vetting a Pool Builder
| |

The questions you ask before you sign anything matter more than anything else.

Word of Mouth & Reading Reviews Intelligently
  • Personal referrals from neighbors, friends, and family are the most reliable starting point
  • Check Google, Yelp, and Facebook before your first meeting — look at the overall pattern, not just the star rating
  • Pay close attention to how the builder responds to negative reviews
  • Look for repeated complaints — communication failures, long delays, unfinished punch lists, billing disputes
  • The best builders often have a waiting list — that alone tells you something

Some of the best pool builders in Texas have minimal social media presence and a basic website. A builder laser-focused on the quality of their current projects simply does not have the bandwidth to also be a content machine. A full pipeline of word-of-mouth referrals is the strongest signal there is in this industry. Look for builders who are known in their communities, not just on their Instagram page.

The First Meeting & What to Ask
  • Come prepared with as many questions as possible about your specific project
  • A knowledgeable builder should speak confidently about your yard, soil, access, and utilities — not just show you a portfolio
  • Ask directly: “Who will be my point of contact throughout the build?”
  • If the answer is a project manager or different team member, ask to meet that person before you commit
  • There is no such thing as a cheap, well-made pool in 2026 — a bid dramatically below market almost always means something is missing

A builder who asks about your septic system, your side yard access, your gas meter location, and your tree canopy before ever talking price is a builder who has done this enough times to know what matters. One who jumps straight to portfolios and pricing without asking about your site is showing you something too.

Speaking With Past Customers & Renderings
  • Any reputable builder should be willing to provide references without hesitation
  • They will give you their strongest references — that is expected. The questions you ask are what matter.
  • Ask: What went wrong during the build and how did the builder handle it?
  • Ask: Did the project finish on time, or did it run long — and by how much?
  • Ask: How was communication — did you have to chase updates, or were you kept informed?
  • Ask: Would you hire them again without hesitation?
  • Ask upfront whether the builder offers free design renderings — many do, some don’t
  • For larger luxury projects involving full outdoor living design, professional design firms can recreate your property in 3D before construction begins
A Note for Home Builders & Building During New Construction
For Home Builders
  • Your pool company choice is a direct reflection of your brand — the customer holds you responsible regardless of who built the pool
  • Vet your pool company the same way homeowners should vet you — track record, quality, responsiveness
  • Your buyers have the right to choose their own pool company — a good builder respects that
  • Cheap pool companies cost you customer relationships. The callback six months after closing is not worth it.
Building During New Home Construction
  • If you are building a new home, this is the most cost-effective time to add a pool
  • The lot is already an active job site — equipment is there, trades are coordinated, ground is already being moved
  • Rolling the pool into your construction financing is almost always the lowest-cost financing path
  • Utility connections — gas, electrical, water — are far simpler and less expensive before the yard is finished
  • You are not required to use the builder’s pool company — you have the right to choose your own. Ask directly: “Can I use my own pool company?”
Follow-Up Questions to Send Before You Sign

Send these in a follow-up email and ask for responses in writing.

  • Does the company carry general liability insurance and workers’ compensation? Ask for a certificate of insurance.
  • What does the contract draw schedule look like? Draws should be tied to construction milestones — not calendar dates.
  • Is there a written project timeline with milestones? Get it before you sign.
  • What does the warranty actually cover — and for how long? Is it the builder’s warranty or the equipment manufacturer’s?
  • What is the change order process? How are scope changes priced and authorized?
  • Does the builder use their own crew or subcontractors? Either can work — but you deserve to know.
  • Who performs the electrical and gas work and do they carry the required credentials?
  • What happens if the builder cannot complete the project? Is there a performance clause?

A builder who is confident in their process will answer every one of these questions clearly and without resistance. Vague answers, pressure to sign quickly, or reluctance to put things in writing are all signals worth paying attention to.

Budget — Everyone Has One. Just Tell Us.
| |

Sharing your budget is one of the smartest things you can do. It saves everyone time and gets you the most pool for your money.

Why Sharing Your Budget Protects You
  • A builder who knows your budget can design to your number from the start — saving everyone time
  • Withholding your budget does not protect you — it slows down the process and leads to designs you cannot afford
  • Most customers go over their original budget — just like they do with homes, cars, and vacations — plan for it and be honest about it upfront
  • Pool pricing in Texas is not one-size-fits-all — the same design with different materials can vary dramatically in price
  • Prices increase year over year — what your neighbor paid two or three years ago is not what you will pay today

When a customer withholds their budget, a builder has to guess. They render a design, spend hours estimating it, present it — and then find out it is $40,000 over what the customer had in mind. Now everyone starts over. Items get cut. The design gets compromised. The process drags out. When you share your number upfront, a good builder designs with that number as the target — not the ceiling.

What Drives Cost Up Most
  • Spa or hot tub — one of the largest add-ons in both cost and complexity
  • Infinity or negative edge — requires a catch basin, additional engineering, and more equipment
  • Water features — scuppers, deck jets, waterfalls, and bubblers all add up
  • Fire features — fire bowls, fire pits, and fire walls require gas lines and additional structure
  • Premium finishes — pebble, quartz, and polished plaster cost more than standard plaster but last longer
  • Outdoor kitchen, pergola, or cabana — once you go beyond the pool the project scope grows quickly
  • Outdoor lighting — landscape lighting, LED pool lighting, and pathway lighting are easy to underestimate
Plan for the Future Now — It's Cheaper Than You Think
  • If you might want a spa later, rough in the plumbing now — a fraction of what it costs to add later
  • If you plan to add landscape lighting, run extra conduit during the build so wire can be pulled through later without digging
  • If outdoor cooking is in your future, stub up a gas line to the patio now — running it later means breaking concrete
  • If you want a fire feature someday, plan the gas line route during construction
  • If you think you will want automation, spec the equipment for it now even if you do not activate everything immediately
  • Same logic applies to autofill systems, chiller capability, and additional conduit for future electrical needs

Stubbing up a gas line during construction might add a few hundred dollars. Running that same line after the concrete deck is poured and landscaping is in could cost several thousand — plus cutting, patching, and repairing everything disturbed. Talk to your builder about your five-year vision for the backyard, not just what you are building today.

Getting Multiple Bids — Do It Right
  • Getting two to three bids is smart and completely normal — most builders expect it
  • Make sure every bid covers the exact same scope — same size, same equipment brands, same finish tier, same features
  • A significantly lower bid almost always means something was quietly removed, downgraded, or left out
  • Ask each builder to walk you through their bid line by line
  • Compare equipment brands and model numbers, finish types, warranty terms, and what is explicitly included versus excluded
Financing Your Pool
  • Pool financing is widely available and more accessible than most people realize
  • You do not have to pay cash — most homeowners finance part or all of their pool
Home Equity Loan

Borrow a fixed lump sum against your home’s equity at a fixed rate. In Texas, home equity loans cannot exceed 80% of your home’s fair market value under the Texas Constitution. Generally the lowest rate option if you have sufficient equity.

HELOC (Home Equity Line of Credit)

A revolving credit line you draw from as needed during construction. Ideal for projects with variable costs. Rates are variable so payments can fluctuate.

Personal Loan

Unsecured, no collateral required, faster approval. Rates are higher than equity products but can work for smaller projects or homeowners who don’t want to leverage their home.

Specialized Pool Loans

Several lenders offer pool-specific financing programs with competitive rates and terms up to 20-30 years. Ask your builder if they have established lending partners.

Building During New Construction

Rolling the pool into your construction loan or primary mortgage typically carries the lowest interest rate of any financing option. This is one of the strongest financial arguments for building during home construction.

Always compare multiple lenders, read the fine print, and consult your financial advisor or CPA regarding any potential tax implications. Rates and terms change, and what is right for one homeowner may not be right for another.

The Construction Process — Trust the Process
| |

Trust the process — every stage has a purpose. The homeowners who have the best experience are the ones who accepted early on that the timeline is an estimate, not a guarantee.

Before the First Shovel Hits the Ground
  • Confirm all permits are approved and active before any work begins — not just submitted
  • Do a final site walk with your builder before layout is staked — confirm pool location, orientation, and height relative to existing patio
  • Confirm the height of the pool shell relative to your existing patio or deck — this affects coping selection and the finished aesthetic significantly
  • Confirm the drainage plan for both the deck and the yard
  • Adjust or cap any irrigation lines in the build zone now — cheapest time to do it
  • Confirm that any future utility stubs are planned — gas lines, water lines, extra conduit

The coping height issue is a perfect example of why this walk matters. If your existing patio is at a certain elevation and your pool shell is formed for a different coping thickness than you expected, the finished waterline may sit noticeably higher or lower than the patio surface. That is extremely difficult and costly to correct after the concrete shell is poured.

The Phases of Construction
Excavation

The yard opens up, dirt piles appear, and it looks like a bomb went off. This is completely normal. It gets worse before it gets better.

Rebar & Plumbing

The steel skeleton of your pool takes shape and plumbing lines are run. This is when any additional utility trenching should happen simultaneously — gas stubs, conduit, water lines. If it was not discussed before, raise it now before the trenches are closed.

Inspection

A city inspector must approve the rebar and plumbing before gunite can be sprayed. This inspection cannot be skipped or rushed. Many cities use online permit tracking portals — ask your builder for the link so you can follow along yourself.

Gunite

The concrete shell is sprayed. Gunite trucks are extraordinarily loud — notify your neighbors in advance. After gunite, the shell needs to cure and this takes time.

Your job after gunite: water the shell. Once the gunite is sprayed, you become part of the curing process. Starting the day after the shell is shot, wet down the entire interior surface with a garden hose at least twice a day — once in the morning and once in the late afternoon or evening. Each session should last long enough to thoroughly saturate the surface, roughly 15 to 20 minutes depending on your pool size. The goal is keeping the concrete damp, not soaking it. The first 7 days are the most critical window — this is when the concrete is developing the majority of its structural strength. Continue watering for a minimum of 7 days and ideally up to 14 days, or until your builder tells you otherwise. In Texas summer heat, do not water during the hottest part of the day — cold water hitting hot concrete can cause surface crazing. Morning and late afternoon are your windows. You cannot over-water gunite. Skipping sessions, however, can lead to shrinkage cracks that affect both the structural integrity of the shell and the quality of the plaster bond later. Your builder will confirm the schedule for your specific project — follow their guidance.

Tile & Coping

The waterline tile and coping stones are set. Natural stone and tile are handcrafted materials — slight variation in color, texture, and grout lines is normal and expected.

Decking & Flatwork

Concrete or paver decks are poured or set. Bonding inspections are required before the deck pour — confirm your builder has scheduled and received approval before concrete is placed.

Plaster

The interior finish is applied. Plaster cannot be applied in extreme heat, cold, or rain. This stage is the most weather-sensitive in the entire build — delays here are common and outside anyone’s control.

Don’t be alarmed by how it looks right after application. Fresh plaster often appears blotchy, streaky, uneven in color, or has a rough texture immediately after it is applied. This is completely normal. In most cases, the crew will return the following day to perform an acid wash and potentially a polish — this removes the surface layer of cement paste, evens out the color, and reveals the true finish beneath. The pool will look dramatically different after this step. Do not judge your plaster finish until after the acid wash is complete and the pool has been filled.

Your pool color will continue to change for weeks after filling. New plaster goes through a curing and hydration process as it interacts with water and pool chemistry. The color you see on fill day is not your final color. Over the first 30 to 60 days, the plaster will gradually brighten, deepen, or shift in tone as it fully cures. The true finished color of your pool typically becomes apparent 4 to 8 weeks after filling. This is normal and expected — it is not a defect.

Fill & Startup

The pool fills and the startup chemical process begins. This is the beginning of a critical 30-day window for your new plaster. Your builder should walk you through startup in detail and give you written care instructions. What you do in the first 30 days directly affects the long-term appearance and durability of your interior finish.

Brushing is your responsibility during the startup period — even if you have a service company. During the first 14 days after plaster, the pool should be brushed at least twice every single day. After the first 14 days, continue brushing once daily through the end of the first month, or until your builder or service company tells you plaster dust is no longer coming off the surface. Brushing removes the plaster dust that naturally sheds from a new surface as it cures, keeps calcium from depositing unevenly, and helps the plaster hydrate and harden uniformly. A pool service company performing your startup visits will brush during their scheduled visits, but they typically come every few days — not daily. The brushing that happens between those visits is on you. This is one of the highest-impact things you can do for the long-term appearance of your pool.

What your service company handles during the 30-day startup: Regular water chemistry testing and adjustment, initial chemical balancing as the plaster cures, equipment monitoring, and scheduled brushing during their visits. This startup period is chemistry-intensive — the water demands much more frequent attention than it will once the plaster is fully cured. Having a professional service company manage this period is strongly recommended. Do not skip it.

Expect Delays — They Are Part of the Process
  • Weather delays are real and unavoidable — gunite and plaster in particular cannot happen in rain, extreme cold, or extreme heat
  • City inspections move on the city’s schedule, not yours or your builder’s
  • Material lead times, delivery issues, and back-orders affect every job at some point
  • Most pool companies rely on subcontractors — gunite crews, plaster crews, electricians, and tile setters all have multiple projects running simultaneously
  • A delay in one phase can create a ripple effect through the phases that follow

What a good builder controls is communication — they should be proactively telling you what is happening, what is coming next, and what is causing any delay. If you are not hearing from your builder, reach out. Ask questions calmly and directly. The vast majority of concerns during construction are either completely normal or easily resolved when addressed early.

Schedules, Neighbors & Crews
  • Have a clear conversation with your builder before construction begins about acceptable work days and hours
  • Know your HOA’s allowed construction hours — violations are your responsibility as the property owner
  • If you have personal preferences — no Sundays, Saturday start no earlier than 9am — communicate them in writing early
  • Many crews work through weekends, especially when weather windows are tight
  • Notify your neighbors before loud events — gunite day, plaster day, concrete pours, and saw work
Porta Potties — Ask That One Is on Site

A porta potty is a basic necessity for any construction crew. Crews without on-site facilities either leave repeatedly — killing productivity — or they find the nearest tree on your property. Neither is acceptable. Ask your builder upfront that one will be provided. A standard construction site rental in Texas runs approximately $150 to $250 per month including weekly service.

Crossing the Finish Line
  • You are not done when the pool looks done — the punch list walk-through is a formal step and it matters
  • Before that walk-through, do your own inspection first — bring a second set of eyes
  • Be thorough but realistic — natural stone varies, grout lines are handmade, and minor imperfections in organic materials are normal and not defects
  • Make a written list and present it calmly and clearly to your builder
  • Ask for a full equipment walkthrough before signing off — pumps, automation, heater, chiller, lighting, water features. You should know how to operate everything.

If you appreciate the work being done, let the crew know directly. Small gestures — waters on a hot day, a pizza for the crew once during the build — are not required, but they are remembered. Crews who feel appreciated tend to bring their best work. However, if there is an issue with the work, bring it to the project manager — not the crew. That is the appropriate channel and it will be resolved far more effectively.

Real Estate Agents, Home Buyers & Sellers with Pools
| |

What every agent and client needs to know before a pool becomes a problem — or a missed opportunity.

For Listing Agents — Know What You're Selling
  • Ask the seller: How old is the pool? Who built it? Has it ever been replastered or had major repairs?
  • Ask for service records, equipment manuals, and warranty documentation
  • Find out if the pool equipment is original or has been updated — age matters
  • Recommend the seller get a pool inspection before listing — surprises at inspection during a contract kill deals
  • If the pool was built between 2016 and 2023 in Central Texas — read the ASR section of this guide before listing
How to Market a Pool Correctly
  • Photograph the pool at golden hour — the lighting is most flattering and dramatic
  • Have the pool running during every showing — water features, fire features, waterfalls, and spa jets all active
  • Turn on pool lighting for evening showings — a lit pool at dusk is one of the most emotionally compelling features a backyard can offer

There is a reason real estate agents suggest baking cookies or bread before an open house — the sensory experience makes a house feel like a home. A pool works exactly the same way. When a buyer walks into a backyard and hears water moving, sees the waterfall running, feels the warmth from a fire feature — they stop being a buyer evaluating a property and start being a homeowner imagining a Saturday evening with friends. A pool that sits flat and still during a showing is a missed opportunity. A pool that is fully alive is a closing tool.

For Buyer's Agents — The Visual Checklist
Pool Shell & Interior Surface
  • Look for cracks — fine hairline cracks can be normal, but map cracking, spider-web patterns, or cracks radiating from corners are red flags
  • Look for white gel-like substance oozing from cracks — this is a potential sign of ASR (see ASR section)
  • Look for rust stains or reddish-brown streaks on the pool interior — indicates corroding steel reinforcement
  • Look for surface spalling — areas where plaster or concrete is flaking, chipping, or crumbling
Coping, Tile & Deck
  • Check for cracked, loose, or missing coping stones
  • Check for loose or popping waterline tile — can indicate shell movement
  • Look for separation between the deck and the pool coping — indicates shell movement
  • Look at deck drainage — does the deck slope away from the pool and the house?
Equipment Pad
  • Note the age of the equipment — pump, filter, heater, automation. Equipment over 10 years old may need attention soon.
  • Look for visible leaks — wet spots, mineral buildup, or corrosion on fittings
  • Ask if there is a heater and/or chiller and confirm both function
Always Recommend a Dedicated Pool Inspection

A standard home inspection covers a pool superficially at best. A dedicated pool inspection by a certified pool inspector is a separate engagement and is worth every dollar. A pool inspector will pressure test plumbing lines, evaluate the structural shell, assess all equipment, and document the full condition of the pool.

ASR — Concrete Cancer: The Most Important Pool Issue in Central Texas Right Now
Critical Information — Pools Built 2016–2023 in Central Texas

ASR (Alkali-Silica Reaction), commonly known as “concrete cancer,” is a chemical reaction that destroys concrete from the inside out. It has no reliable cure once it begins. In most cases, it requires complete pool demolition and rebuilding. The most notable outbreak in the United States is in Austin, Texas.

What Is ASR?

ASR stems from the accidental use of reactive aggregate in a concrete mix. When moisture contacts the reactive aggregate, a gel forms and continues to swell, fracturing the concrete and allowing more moisture to enter — a cycle of increasing damage. In Central Texas, a combination of reactive local aggregates and a shortage of the additive fly ash (which prevents ASR) during COVID-19 supply chain disruptions created widespread conditions for ASR development in pools built without proper mix protection.

The Risk Window

The prevalence of concrete cancer in Central Texas pools has primarily been observed in pools constructed between 2017 and 2023. ASR formation generally takes two to four years to develop — meaning visible signs often appeared two to four years after the pool was built. Cases have also been reported in Dallas/Fort Worth, San Antonio, and Houston.

Visual Signs of ASR
  • Map cracking or spider-web crack patterns across pool walls or floor
  • White gel-like substance seeping from cracks — one of the most definitive visual indicators
  • Rust stains or reddish-brown streaks on the shell surface
  • Separation from stairs, benches, or the pool deck
  • Recurring cracks that reappear after being patched
  • Bulging or bowing pool walls in advanced cases
ASR Testing
Rapid Gel Testing

A field test using chemical reagents. Results in approximately 72 hours. Available at approximately $2,000–$2,500 from Central Texas specialists.

Petrographic Lab Testing

The definitive lab analysis required for insurance claims and litigation. Costs range from $7,000 to $12,000 depending on samples required.

ASR Testing Specialists:

For Sellers: If your pool was built between 2016 and 2023, proactively getting a core sample test before listing is one of the most powerful things you can do. A clean test result eliminates buyer hesitation and demonstrates transparency. It is far less expensive than losing a buyer over ASR uncertainty.

For Buyers: If the pool falls in the risk window and has not been tested, request testing as a condition of the contract or negotiate a price adjustment that accounts for the unknown risk.

Pool Age & Equipment — A Quick Reference for Agents
  • Under 5 years old — should be in good condition; focus on ASR risk if built 2016–2023 in Central Texas
  • 5–10 years old — equipment approaching mid-life; heaters, pumps, and automation may need attention soon. Plaster may show normal wear.
  • 10–15 years old — equipment likely needs updating; plaster may need resurfacing; coping and tile should be examined carefully
  • 15+ years old — full equipment evaluation recommended; replastering likely needed or already done
  • 20+ years old — factor in the cost of bringing the pool fully up to date when evaluating the property

Pool Equipment, Features & Add-Ons
| |

The equipment you choose determines how much you enjoy your pool, how much it costs to run, and how easy it is to maintain. These decisions deserve as much attention as the pool design itself.

Autofill Systems — A Must-Have, Not an Option
  • An autofill system automatically maintains your pool’s water level without you ever dragging a hose out
  • In Texas summers, pools can lose several inches of water per week to evaporation — without an autofill, your pump and skimmer can run dry, causing expensive damage
  • Connects directly to your water supply line and uses a float valve mechanism — opens when water drops below the set level, closes when it reaches it
  • This is one of the most practical and inexpensive provisions you can add during a new build — far more difficult and costly to add after construction
  • Two types: mechanical float systems (simple, reliable, no electricity) and electronic sensor systems (more precise, can integrate with automation)
  • For vanishing edge pools, a dedicated autofill plumbed into the catch basin is essential
  • For STR and Airbnb properties, an autofill is non-negotiable — you cannot check water levels remotely
Salt vs. Chlorine — The Most Misunderstood Decision

Common misconception: Salt pools are NOT chlorine-free. A salt system uses electrolysis to convert dissolved salt into chlorine — you are still swimming in chlorinated water, just at lower and more consistent levels generated automatically rather than added manually.

  • Once the salt-turned-chlorine sanitizes the pool, it converts back into salt and the cycle repeats — a near-continuous, self-renewing supply of chlorine
  • The difference: chlorine is generated automatically — more consistent levels, softer-feeling water, less chemical handling
  • Salt pools are not maintenance-free — salt levels, pH, and chlorine output still require regular monitoring
Salt System Advantages

Water feels noticeably softer and silkier. Chlorine levels lower and more stable — less eye and skin irritation. No storing or handling liquid chlorine. Lower day-to-day chemical costs once the system is installed.

Salt System Considerations

Higher upfront cost — installing a saltwater chlorine generator ranges from $1,000 to $2,500 or more, and the salt cell needs replacement every three to seven years. Salt can be mildly corrosive to certain metals and some natural stone — material selections around the pool should account for this.

Traditional Chlorine

Lower upfront cost. More service professionals familiar with chlorine maintenance. No salt cell to clean or replace. Effective and proven over decades of use. Requires regular purchasing, storage, and handling of chemicals.

Salt is the preferred choice for most Texas homeowners building a new pool today — the water quality experience is noticeably better and the long-term maintenance cost advantage is real. But go in understanding that salt and chlorine are not opposites — they are the same outcome reached by different means.

Ozone, UV & AOP — Secondary Sanitization Systems

These systems work alongside your primary sanitizer to dramatically improve water quality, reduce chemical consumption, and eliminate the chlorine smell and irritation most people associate with pool water. None replace chlorine entirely — they reduce how much is needed.

UV (Ultraviolet)

Uses UV-C light to destroy bacteria and viruses at the DNA level as water passes through a chamber. Does not oxidize. Reduces chlorine demand and breaks down chloramines. Entry-level secondary sanitization.

Ozone

Generates ozone gas injected into the water circulation, destroying bacteria, algae, and organic contaminants through oxidation. Significantly stronger than chlorine as an oxidizer. Can reduce chlorine demand by 50–75%. Does not hold a residual — a low chlorine level is still maintained.

AOP (Advanced Oxidation Process)

The most powerful secondary sanitization option for residential pools. Combines ozone and UV to create hydroxyl radicals — highly reactive oxidizers even stronger than ozone alone. Dramatically reduces chlorine demand, eliminates pool smell, and produces noticeably clearer, softer-feeling water. Higher upfront cost but the performance difference is significant.

For most new pool builds, AOP is the premium choice if budget allows — the water quality difference is immediately noticeable. Ozone is an excellent mid-tier option. UV is a solid entry-level upgrade over standard chlorine alone. If you are debating between upgrading finishes or upgrading your sanitization system, strongly consider the sanitization — you feel it every time you swim.

Heaters — Gas vs. Heat Pump

 

Gas Heater (Natural Gas or Propane)
  • Heats pool water fast — approximately 2°F per hour, raising temperature 15–20 degrees overnight
  • Works in any weather, any temperature — performance does not depend on outdoor conditions
  • Best for: pools used occasionally on weekends, spa heating where quick temperature rise matters, or properties without reliable electrical access
  • Higher operating cost with regular use
  • If gas service is on the opposite side of the house, a gas line run can add significant cost — plan for this early
Heat Pump
  • Extracts heat from surrounding air — extremely efficient. COP rating of 5.0–7.0 means 5–7 units of heat per unit of electricity consumed.
  • Much lower monthly operating cost than gas — ideal for maintaining consistent temperature throughout the season
  • Slower to heat — raises temperature at 1–1.5°F per hour
  • Requires outdoor air temperature above approximately 45–50°F to operate efficiently
  • Higher upfront cost, lower long-term operating cost

For most Texas pool owners, the ideal setup is a heat pump as the primary heater for the extended Texas season, paired with a gas heater or the option to add one later for the occasional cold snap or for quick spa heating. Texas winters are mild enough that a heat pump handles the shoulder seasons beautifully. If you have a spa, a gas heater for the spa specifically is worth serious consideration — the speed advantage is most noticeable when heating a small volume of water to 100°F on a cold evening.

Chillers — The Most Underrated Equipment Decision in Texas
  • In Central Texas, a pool without a chiller can reach 90°F or above by late summer — that is not swimming, that is a warm bath
  • Pool chillers can lower water temperature 10–15°F efficiently and also reduce chemical consumption by 20–25%
  • Algae and bacteria thrive in warm water — a chiller keeps water chemistry more stable and reduces chemical demand naturally
  • Darker plaster colors absorb significantly more heat — if you choose a dark finish, a chiller is not optional, it is essential
  • Many modern heat pump systems are available as combination heater-chiller units — one piece of equipment handles both functions depending on the season
  • The cost of adding chiller capability during the build is significantly less than retrofitting it later
Filtration — Cartridge vs. Sand<
Cartridge Filters

Capture particles as small as 10–15 microns — providing clearer water than sand. More energy-efficient, work at lower pressure, and require no backwashing, saving thousands of gallons of water per year. Maintenance involves hosing down the cartridge periodically. Cartridges need replacement every 1–3 years depending on use. Better choice for most suburban and Hill Country properties where water clarity is the priority.

Sand Filters

Filter particles down to 20–40 microns. Require backwashing periodically — this wastes water and removes pool chemicals. Sand media lasts 5–10 years. More durable in high-debris environments. Lower upfront cost.

For most new pool builds in Austin and the Hill Country, a cartridge filter is the preferred recommendation — finer filtration, no water waste from backwashing, and lower operating pressure on the pump. However, if your property has heavy tree debris load — large oaks, abundant cedar, or significant pollen — a sand filter’s simpler cleaning process may serve you better in practice. Ask your builder what they recommend for your specific site conditions.

Pool Automation — Control Everything From Your Phone

Pool automation allows you to control every piece of equipment — pump speed, lighting, heater, chiller, water features, spa jets, and more — from a smartphone app, tablet, or voice assistant. For most new pool builds in 2026, automation is not a luxury — it is the expected standard.

What automation controls:
  • Variable speed pump scheduling — run at low speed during off-peak hours, high speed for cleaning cycles
  • Heater and chiller — set desired temperature, program it to be ready when you arrive home
  • Lighting — color, brightness, scheduling, and light shows
  • Water features — waterfalls, scuppers, deck jets, bubblers
  • Spa jets and air blowers
  • Freeze protection — automatically runs the pump when temperatures approach freezing
Leading Systems:

Jandy iAquaLink — Excellent app, voice assistant compatibility with Alexa and Google Home. Works best with Jandy equipment. jandy.com

Pentair IntelliCenter — The most common system in new construction. Touchscreen panel, full app control. pentair.com

Hayward OmniLogic — Premium platform for complex, multi-feature pools. hayward.com

The energy savings from proper pump scheduling alone can offset a significant portion of the automation system cost over time. A variable speed pump on an optimized schedule uses dramatically less electricity than a single-speed pump on a fixed timer. If you are building a new pool, spec the automation in from the start — retrofitting later is possible but more expensive.

Automatic Valves vs. Manual Valves
Where automatic valves make sense:
  • Pool-to-spa water diverter — switching between pool and spa mode with your phone
  • Waterfall or water feature circuits you want to toggle from the automation panel
  • Any valve in an inconvenient or difficult-to-reach location
Where manual valves make sense:
  • Maintenance isolation valves — these should always be manual: simple, reliable, and no electronics to fail at the wrong moment
  • Return line balancing valves — set once and left alone
  • Drain and waste lines — infrequently used, no need for motorization

Not every valve needs to be automated — and not every valve should be. Your builder should be designing a system where automation handles convenience and manual valves handle isolation.

Living Water & Water Features — Transforming the Pool Experience

Living Water: One of the most underappreciated elements in pool design is what moving water does to the entire pool experience. Still water shows your pool one way. Active water — from sheers, bubblers, deck jets, or waterfalls — creates constant refraction that makes plaster colors shift, shimmer, and dance in ways a static pool never can. Pool lighting reflecting off moving water creates a living, pulsing effect that transforms the backyard after dark. Fire features reflecting off a pool with active bubblers or sheers create an effect that has to be seen to be described. Moving water also naturally masks neighborhood noise, traffic, and the general sounds of suburban life — creating a sense of privacy and enclosure even on an open lot. Many pool owners say this ambient sound is the feature they appreciate most in daily life.

The Full Water Features Menu
Bubblers (Gushers)

Small jets installed in shallow areas — tanning ledges, Baja shelves, beach entries, and steps — that push water upward from below the surface. Create a playful bubbling effect, gentle sound, and beautiful light play when paired with LEDs. Height and intensity are adjustable. Best specified in odd numbers for visual balance.

Deck Jets & Laminar Jets

Arching streams of water that shoot from the pool deck into the pool. Laminar jets produce a smooth, glass-like arc — a solid tube of water. When lit with LEDs they appear as glowing rods of light at night. These also aid in water circulation and help cool the water.

Scuppers

Architectural spouts or slots mounted on raised walls, columns, or bond beams that allow water to flow into the pool. Produce a consistently pleasing sound and require minimal operating cost as most run off the primary pool pump.

Sheer Descents (Sheetfalls / Cascade Waterfalls)

A thin, wide ribbon of water falling in a smooth, glass-like curtain from a raised wall. The visual effect is clean and modern. Sound ranges from nearly silent to rushing, depending on the length of the fall. Available in widths from one foot to eight feet. Pairs beautifully with contemporary and geometric pool designs.

Rock & Natural Waterfalls

Built from natural or manufactured stone — resort-like and organic. Work beautifully with free-form pool designs. Slides can be incorporated into waterfall structures. Require their own dedicated booster pump and more maintenance than other features.

Rain Curtains

Individual streams falling from a pergola or overhead beam in a curtain pattern. Creates a dramatic enclosure effect. Best suited for larger projects with outdoor structure elements.

Spillover Spas

A spa positioned above the pool level that overflows its edge, creating a continuous cascade of heated water. One of the most efficient water feature arrangements — the spa’s circulation pump provides the feature with no additional pump required.

Water Bowls & Fire-Water Bowls

Decorative vessels mounted on columns, raised walls, or pool perimeter structures. Fire-water bowl combinations — where a flame burns inside or above the bowl while water flows from it — are one of the most visually stunning features available in luxury pool design. Requires both a gas line and a water line.

Fire Features — Extending the Experience Year-Round

Fire features transform the pool area from a daytime amenity into a year-round destination. The combination of fire and water — particularly in the Hill Country and Austin outdoor setting — is one of the most compelling features in luxury backyard design.

Fire Bowls

The most popular pool fire feature. Vessels of varying size mounted on columns, pedestals, or integrated into raised walls. Available in copper, stainless steel, cast stone, and GFRC. Fill options include lava rock, river stone, or colored fire glass. Fire-and-water combination bowls — where a scupper or spout flows beneath or around the flame — create one of the most dramatic visual effects in backyard design. Can be controlled through pool automation apps.

Linear Fire Features (Fire Walls)

Long, low-profile flame channels running along pool perimeter walls or bond beams. Sleek, architectural look suited to modern and geometric pool designs.

Fire Pits

Built into the pool deck or patio area, either sunken or raised. Create natural gathering zones adjacent to the pool. Available in natural gas, propane, or wood-burning configurations.

Fuel Considerations

Natural gas is most convenient for permanent installations — instant ignition, no tank management. Propane works for properties without a gas line. Remember: if there is any possibility of adding fire features in the future, stub up a gas line to the intended location during the original build. Running a gas line under finished concrete and established landscaping costs significantly more than planning for it during construction.

All fire features installed near pools must comply with NFPA (National Fire Protection Association) standards. Automatic shut-off valves, proper clearances from combustible materials, and professional gas line installation by a licensed plumber are non-negotiable.

Design Add-Ons — Tanning Ledges, Slides, Grottos & More
Tanning Ledges (Baja Ledges)

A shallow platform — typically 6 to 12 inches of water depth — built into the pool. Designed for lounging with the body partially submerged. Extremely popular and one of the most requested features in Texas pool builds. Ideal for lounging chairs, young children, pets, and bubblers. Note: the plaster on the tanning ledge will always appear lighter than the rest of the pool due to shallow depth — this is normal and should be considered when selecting your plaster color.

Built-In Benches & Seating

Built-in benches incorporated along pool walls, in corners, or in the spa. Provide a comfortable place to sit in the water at varying depths and add visual structure to the pool interior. Excellent for entertaining — adults can sit comfortably and socialize without treading water.

Umbrella Holders

Small stainless steel or PVC sleeves embedded in the tanning ledge or pool deck at the time of construction that accept a standard umbrella pole. Allows shade to be positioned directly over loungers. An inexpensive add-on during construction that is nearly impossible to add cleanly after the fact.

Hydrotherapy Jets

Jet systems installed in pool walls or benches providing water massage therapy. Common in spas but also available in standard pool seating areas.

Water Slides

Options range from standard residential slides in multiple colors and configurations to fully custom-built slides incorporating natural stone, landscaping, and waterfall integration. Pool depth at the landing zone must be sufficient — your builder will confirm depth requirements. A great addition for families and adults who want more than a place to float.

Grottos

A recessed cave-like enclosure built behind or beneath a waterfall structure, typically with a bench inside. Sitting inside a grotto with water cascading in front creates one of the most immersive pool experiences available. Built from natural stone — not manufactured fake stone. A substantial investment but one of the most memorable features a pool can have.

Counter-Current Swimming Systems — A Lap Pool Without the Space

If you love to swim for exercise but do not have the space or budget for a full lap pool, a counter-current swimming system turns any pool into an endless swimming machine. A powerful pump and specially engineered nozzles create a strong, adjustable current to swim against in place.

BADU Jet (by Speck Pumps)

The most widely recognized counter-current system globally, available in multiple models. Can be installed in new gunite builds with flush-mounted nozzles for a clean, integrated look, or in existing pools using an over-the-wall hanging unit requiring no major structural work. Models range from the Inspiration (entry-level, dual nozzle) to the Turbo Pro (premium, 4HP motor, approximately $12,000–$15,000 installed).

Endless Pools Fastlane

A premium alternative producing a wide, turbulence-free current wider than the swimmer’s body and deeper than any swim stroke. Available in new builds and retrofit installations. App-controlled with variable speed from near-zero to race pace.

Riverflow by Current Systems Inc.

Designed for serious training and intense cardio workouts. Produces an extremely powerful, adjustable current. Range: approximately $20,000–$22,500 for the unit, plus installation.

New build integration produces the cleanest look — nozzles flush-mounted and invisible when not in use. Retrofit over-the-wall systems are available for existing pools. Confirm minimum pool size requirements with your builder before spec’ing. These systems require a dedicated electrical circuit. If swimming for fitness is a priority, plan for this during the original build.

Chlorine-Free Pools — What's Actually Available in 2026
Mineral Sanitizers

Silver and copper ions inhibit bacteria and algae growth. Often combined with a small residual chlorine level. Reduces chlorine demand significantly but rarely eliminates it entirely.

Hydrogen Peroxide-Based Systems

Uses dissolved oxygen and copper ionization to sanitize without chlorine. Can work as a true chlorine alternative in some applications. Requires very consistent monitoring. Not universally accepted by all health codes.

Hydroxyl-Based AOP

The most advanced approach to reducing chlorine to near-drinking-water levels — as low as 0.5 ppm or less — while maintaining fully safe pool water. The most practical path for families with genuine chlorine sensitivity concerns when combined with a salt system running at very low output.

Pool Covers — Protection, Safety & When You May Not Need One
What a Pool Cover Does For You
  • Reduces water evaporation — a covered pool can lose significantly less water, which matters in Texas summers
  • Retains heat — dramatically reduces heat loss overnight, lowering heater and chiller operating costs
  • Reduces chemical consumption — cooler, covered water is more chemically stable
  • Keeps debris out — leaves, pollen, insects, and dust stay out of the water and off your filter
  • Adds a layer of child and pet safety when the pool is not in use
When You May Not Need a Cover
  • If your property has no shedding trees nearby and your backyard is relatively open, debris management is minimal
  • If you swim daily or multiple times per day, a cover requiring removal and replacement may create more friction than value
  • If you do not heat your pool, the heat retention benefit is largely irrelevant
Automatic vs. Manual

Automatic covers open and close with the push of a button. A pool cover only delivers benefits when it is used consistently — and convenience determines consistency. Automatic covers cost $12,000 to $22,000. They can meet ASTM F1346 safety certification, qualifying in many Texas municipalities as a pool barrier in lieu of a fence. Cover fabric needs replacement every 6–8 years at approximately $4,000–$6,000. Works best on rectangular pools.

Manual covers cost $1,500 to $6,000 installed. Less likely to be used consistently because the effort involved is a barrier. Pin-down safety covers that anchor to the deck do qualify as ASTM safety covers.

DIY Pool Care vs. Hiring a Service Company
| |

Your time has value. Protecting your investment matters. This comes down to two things: how much of your time you are willing to dedicate, and how much it would cost you if something goes wrong because maintenance slipped.

What Proper Pool Maintenance Actually Requires
  • Water chemistry testing and balancing — at minimum weekly, more often in heavy use or extreme Texas heat
  • Brushing pool walls and floor to prevent algae from establishing on the surface
  • Skimming debris from the surface and emptying skimmer baskets
  • Cleaning or backwashing the filter on a schedule
  • Inspecting equipment — pump, heater, automation — for any signs of issues
  • Monitoring water level and managing evaporation
  • Seasonal adjustments to chemical programs as temperature and use patterns change
  • Responding immediately when something looks wrong

Every one of these items has consequences if neglected. Water chemistry out of balance for even a short period in Texas summer heat can lead to algae blooms that are expensive and time-consuming to remediate. Equipment issues caught early are minor repairs. The same issues left unaddressed become major ones. The learning curve to do this properly is real.

The Case for Hiring a Professional Service Company
  • Your time is worth something. Professional pool service typically runs $150 to $300 per month — roughly $5 to $10 per day to have a trained professional managing one of the largest investments in your property.
  • A professional service company delivers consistency regardless of your week — your pool gets serviced on schedule whether you are at the office, on vacation, or simply enjoying a Saturday
  • Good pool technicians catch things you will not — a pump running hot, a filter approaching its limit, an o-ring beginning to fail — before any of those become expensive repairs
  • The cost of a single avoided equipment failure often covers months of service fees
  • For STR and Airbnb properties, professional service is non-negotiable — a green pool on a guest arrival day is a one-star review, a refund demand, and a direct hit to your listing ranking
  • Peace of mind is a real and valuable thing — knowing your pool is properly managed every week, that the water is balanced and nothing is being missed, is worth something independent of the direct cost

Pool ownership should be enjoyable. Worrying about it should not be part of the experience. The investment in professional service is an investment in actually enjoying what you built.

If You Choose to DIY — Do It Right

Many pool owners successfully maintain their own pools and find genuine satisfaction in it. The homeowners who do it successfully share one trait: they invested time upfront to understand their specific pool, equipment, and water chemistry before the pool was ever filled.

  • Establish a non-negotiable weekly maintenance schedule and stick to it regardless of how the water looks
  • Invest in quality water testing equipment — a reliable liquid reagent test kit or digital tester, not just strips
  • Learn your pool’s specific chemistry tendencies — every pool behaves differently based on size, exposure, plaster type, and use patterns
  • Respond immediately when something looks or sounds different — do not wait to see if it resolves
  • Know when to call a professional — for equipment diagnosis, chemical remediation, or anything beyond your comfort level

The homeowners who struggle with DIY pool maintenance are almost never the ones who lack the ability — they are the ones who underestimated the commitment. Skipping a week of testing because the water looks clear, guessing at chemical additions without testing first, or ignoring a small equipment issue are where DIY pool care most commonly goes wrong.

The Hybrid Approach & Vetting a Service Company
The Hybrid Approach

Many Texas pool owners find the most practical solution is a combination — professional service weekly for chemistry, brushing, and equipment checks, combined with daily observation by the homeowner and occasional owner involvement for simple additions between visits. This gives you professional consistency while keeping you educated and connected to your pool.

Vetting a Pool Service Company
  • Ask for references from current customers in your specific area
  • Verify they carry general liability insurance and TDLR credentials for any electrical work
  • Get a written service agreement that clearly defines what is included — weekly chemical testing, equipment checks, brushing, skimming, and filter maintenance
  • Ask how they handle equipment issues — do they diagnose and repair, or simply alert you and refer you out?
  • Confirm they provide a written visit report after each service — you should know exactly what was done and what the water chemistry read on every visit
  • Ask about their response time for between-visit issues

The cheapest pool service is almost never the best pool service. A technician rushing through too many pools per day to hit a low price point is not checking your equipment carefully, not testing your water thoroughly, and not catching the early signs of problems. The consequences of poor pool service show up slowly — in plaster deterioration, scaling, algae, and equipment wear — before they show up dramatically as an expensive repair. Find a company that communicates well, shows up consistently, and genuinely understands your pool. Pay fairly for that.

Pool Safety — Layers of Protection
| |

Drowning is the leading cause of accidental death for children ages 1 to 4 in the United States. 88% of drowning incidents occur while an adult is present — often inside the house. 70% happen during non-swim times when no one expects a child to be near the water. No single measure is enough. Pool safety works in layers.

Layer 1 — The Barrier (Your Fence)

Your first and most important line of defense. A compliant pool fence with a self-latching, self-closing gate physically prevents unsupervised access before anyone reaches the water.

  • Minimum 48 inches tall, no chain link, gaps no larger than 4 inches
  • Self-closing, self-latching gate that swings away from the pool
  • Latch on the pool side, minimum 54 inches from the ground
  • Check your local municipality for requirements that may exceed state minimums
Layer 2 — Door & Window Alarms

If your home’s back door or any window provides direct access to the pool area, that door or window is part of your pool barrier — and it must be treated that way.

  • Door alarms that sound when a door is opened are one of the most effective early warning tools available
  • Window alarms for any window that opens to the pool area
  • Self-closing, self-latching mechanisms on doors leading directly to the pool
  • Smart door sensors that send an alert to your phone when a door is opened — particularly useful during evening hours and for toddler households
  • Even some pet doors have been identified as pool access points for young children — this is worth considering
Layer 3 — Pool Alarms

Pool alarms detect when someone or something enters the water and sound an alert. They are a reactive layer — they activate after entry — but they buy critical seconds.

Floating Surface Alarms

Float on the water surface and detect waves or disturbance from an object entering the pool. Look for adjustable sensitivity models to reduce false triggers from wind or rain.

Subsurface / Immersion Alarms

Installed below the water surface and detect pressure changes from an object entering the water. More precise than surface alarms with fewer false triggers.

Gate Alarms

Mounted on pool gates to sound when the gate is opened. A simple but valuable addition — most drowning incidents involve gates that were unlocked or unsecured.

Wearable Alarms

Worn as a wristband by children. Activate an alarm when submerged. Provide the most immediate and child-specific protection because the alarm is on the child — it does not depend on the child reaching the pool area to trigger.

For households with toddlers, the most effective combination is a wearable alarm paired with a gate alarm. Toddlers are unpredictable and move fast. These two layers together provide detection at both the point of gate access and the point of water contact.

Layer 4 — Pool Cameras & AI Monitoring
Smart Pool Cameras (AI-Based)

Systems like SwamCam use artificial intelligence to detect human presence in the pool area and send immediate alerts to your phone. Continuously scan the pool area, can distinguish people from pets or shadows, and provide live viewing from anywhere. Certified to ASTM F2208 standards. Particularly valuable for vacation rental properties and families wanting an additional real-time awareness layer.

AI Drowning Detection

More advanced systems like MYLO monitor swimmers already in the pool using above and below-water cameras that can identify the characteristics of a drowning incident — a motionless or submerged swimmer — and trigger an alert.

No camera or alarm system replaces active adult supervision. These tools are supplemental layers — they buy you time and provide backup when supervision is imperfect. They are not a substitute for eyes-on attention, particularly with young children.

Layer 5 — Swim Lessons, CPR & Additional Safety

div class=”h4-label”>Swim Lessons

Swimming ability significantly reduces drowning risk. The American Red Cross and USA Swimming Foundation both offer learn-to-swim programs for children as young as 6 months. Even basic water competency — the ability to roll to the back and float — can be life-saving for a young child who falls into a pool unexpectedly.

CPR Training

Every adult in a household with a pool should be trained in CPR. Drowning incidents that result in survival almost always involve immediate bystander CPR before emergency services arrive. The American Red Cross and American Heart Association both offer courses widely available in Austin and the Hill Country area. This is not optional — it is the most important layer of protection you can provide.

Additional Considerations
  • VGB Compliance — requires anti-entrapment drain covers on all residential pools. Your builder handles this for new builds. For older pools, confirm your drain covers are VGB-compliant.
  • Life-saving equipment — a reaching pole and ring buoy should be mounted in a visible, accessible location near the pool
  • Pool rules — for STR and vacation rental properties, clear written pool rules posted at the pool are both a safety measure and a liability protection
  • Pet safety — dogs can and do fall into pools. Ensure pets have a way to exit the pool if they fall in (a ramp or designated entry point)

Pool ownership and pool safety are inseparable. The time and cost of implementing these layers of protection is a fraction of what any incident would cost — financially, emotionally, and legally. Build safety into your pool from day one and maintain it every day after.
