Questions to Ask a Pool Builder Before You Sign
Every list of questions to ask a pool builder includes the same three: how much, how long, and can I see photos.
Those are fine. They're also the questions every builder has a polished answer ready for, which makes them nearly useless for telling one company from another.
The questions that actually distinguish builders are the ones about what happens when something goes wrong. Nobody rehearses those, because most homeowners never ask them.
Here's what to ask, why each question matters, and more usefully, what a good answer sounds like versus an evasive one.
Ask these of every builder you're considering, including us.
Questions about the structure
The shell is the part you can never inspect again after week two. It's also where cutting costs is easiest and least visible.
"What does your gunite test at, and how do you know?
The figure to expect is around 4,000 PSI. The important half of the question is the second half. A supplier worth using shoots test panels and pulls cores to verify strength rather than asserting it. A builder who can describe how their supplier verifies is telling you they've asked. One who just repeats a number may never have.
"How thick are the shell walls and floor?"
Ask for a number. We build to a minimum of nine inches through both. In expansive North Texas clay that changes volume with every wet and dry cycle, shell thickness is structural, not a specification you can economise on and add later. A builder who hesitates on this question is a concern.
"Do you pressure-test the plumbing before it's covered?"
The answer should be an immediate yes, and you should ask to be there or to see documentation. Once gunite and decking cover the plumbing, a bad fitting is a demolition job rather than a repair. This is the single cheapest problem to catch and the most expensive to miss.
"Who's watering my shell, and for how long?"
Gunite gains strength through hydration, not by drying out. A shell left to bake through a Texas summer week can shrink and crack, and the strength it fails to develop is gone permanently. We ask homeowners to water their shell during early curing. If a builder has no answer to this question at all, they may not be managing the cure. More on why this matters.
"When do you plaster after gunite?"
Twenty-eight days is the industry standard, and it exists as a conservative window covering a range of mix qualities. A builder plastering substantially earlier should be able to explain precisely why.
Questions about the money
"What's your draw schedule tied to?"
This is the most important question on the page.
Draws tied to completed and inspected milestones protect you. Draws tied to calendar dates do not. With milestone draws, work has to exist before it's paid for. With date-based draws, you can make several payments into a project that has stalled.
A builder confident in their scheduling has no reason to object. Hesitation here tells you something.
"How large is the deposit, and what does it cover?"
A large upfront deposit moves risk from the builder to you before any work is done. Ask what specifically it pays for.
"Show me the allowances, and tell me what happens when I exceed them."
Bids often include allowances, a budgeted figure for stone, tile, or decking. If what you actually choose costs more, you pay the difference. A low bid with thin allowances is a number engineered to win a comparison rather than to predict your final invoice. Get the allowance figures in writing and price your actual selections against them before you sign.
"What's excluded?"
Common exclusions: fencing, gate modifications, landscape repair, irrigation relocation, electrical panel upgrades, and the cost of difficult site access. None of these is dishonest to exclude. All of them become problems when the homeowner doesn't notice.
"How are change orders handled and priced?"
You want a written process with pricing agreed before work proceeds, not a running tab you see at the end.
"How will I know your subcontractors and suppliers have been paid?"
This is the question almost nobody asks, and in Texas, it matters more than it sounds. Unpaid subcontractors and suppliers may be able to file a lien against your property even if you have paid your builder in full. Ask whether the builder provides lien waivers or releases as draws are paid. The lien exposure is explained.
Questions about people
"Who will actually be on my property, and who is my single point of contact?"
You want one name. Pool construction involves multiple crews and trades, and the difference between a smooth build and a frustrating one is usually whether one person is coordinating them or nobody is.
At Canyon Oak Pools, Larry personally manages every project we take on. That's unusual in this industry, which is exactly why we say it.
"Are your crews employees or subcontractors, and are they the same crews every time?"
Neither answer is wrong. Consistency is what matters. A builder using the same gunite crew for years has a different quality control situation than one using whoever's available.
"What happens if I have a problem after handover?"
Ask what's warranted, for how long, by whom, and what the process is for getting someone out. Equipment manufacturer warranties and the builder's own workmanship warranty are separate things.
"Will I get an orientation on my equipment?"
You should not be handed a full pool and a folder. Our Equipment Services Manager, Ryan Curtis, runs Pool School with every client before they swim chemistry, cleaning, and how their specific equipment actually works.
Questions about verification
Don't accept answers to these. Check them.
"What licences do you and your trades hold?"
Then verify them yourself with the Texas Department of Licensing and Regulation rather than accepting a screenshot. Be aware that published guidance disagrees about whether Texas requires a statewide licence specifically for pool construction. What isn't disputed is that electrical work is a licensed trade. Confirm who's doing your electrical and that they're licensed for it.
"Can I see your certificate of liability insurance?"
Check its current, not expired. Ask about workers' compensation coverage, too.
"Can I speak to three clients whose pools you finished in the last year, within twenty miles of me?"
The constraints matter. Recent, local, and completed. A builder with a good year has these ready. Hand-picked references from five years ago tell you less.
"Can I see a pool you're building right now?"
An active site tells you more than a finished one. Is it organised? Is it fenced? Does it look like a place where careful work happens?
Questions about what goes wrong
These are the ones that separate people.
"What's the longest a build of yours has taken, and why?"
Everyone has one. A builder who says they've never had a delayed project is either new or not being straight with you. What you're listening for is a specific, unembarrassed explanation.
"What happens if you hit a rock, a utility line, or a drainage problem I don't know about?"
You want to know how a genuine site surprise is handled contractually, and how it differs from a change you requested.
"Who provides construction fencing, and when does it go up?"
Some North Texas cities require construction fencing from the moment excavation begins until the permanent barrier is finished. McKinney explicitly does, citing both cave-in and drowning risk. If a builder doesn't know this, ask what else they don't know. More on construction-phase safety.
"What's your process if I'm unhappy with something?"
Listen for a process rather than a reassurance.
What the red flags actually are
A large upfront deposit relative to the contract value
Draws are tied to dates rather than inspected milestones
A vague contract with broad allowances and thin exclusions
No single point of contact
Unwillingness to show recent local work or references that are all several years old
Pressure to sign quickly, or a discount that expires
A bid substantially below everyone else's. Not a bargain, a signal that something is missing from the scope, the materials, or the company's ability to finish
Evasiveness on technical questions. A builder who can't tell you their shell thickness either doesn't have a standard or doesn't want you to know it
How to read the answers
The content of an answer matters less than its shape.
Specific beats reassuring. "Nine inches, walls and floor" is an answer. "We use only the highest quality materials" is not.
A builder willing to tell you something unwelcome is worth more than one who agrees with everything. If someone tells you your budget doesn't cover what you're describing, or that your lot needs retaining work you weren't expecting, that's a good sign rather than a bad one.
Watch what happens when you ask a hard question. Comfortable and direct is good. Defensive is worth noting.
We were awarded the Better Business Bureau Torch Award for Ethics in 2024, in an industry that Larry will readily tell you hasn't always deserved a good reputation. That's the context you're buying into. Ask hard questions of everyone.
Frequently asked questions
What's the single most important question to ask a pool builder? What the draw schedule is tied to. Payments released against completed and inspected milestones mean work must exist before it's paid for. Date-based draws mean you can have several payments into a stalled project.
How many bids should I get? Three is usually enough to see the range. More than that, and you're comparing documents rather than builders. What matters is comparing them line by line, allowances, exclusions and change-order terms rather than bottom line to bottom line.
Should I always avoid the cheapest bid? Not automatically, but understand why it's cheapest. Usually, it's thinner allowances or a narrower scope, with the difference arriving later. A bid far below the others is more often a warning than a bargain.
How do I check whether a pool builder is legitimate? Verify licences directly with the Texas Department of Licensing and Regulation rather than accepting the builder's word, check their Better Business Bureau profile for complaint history rather than just the rating, ask for a current certificate of insurance, and speak to recent local clients.
What should I ask about warranties? What's covered, for how long, by whom, and what the process is for a service call. Builder workmanship warranties and equipment manufacturer warranties are separate; get both in writing and register the equipment yourself.
Is it rude to ask a builder about projects that went wrong? No, and the reaction is informative. Every builder with real volume has had a difficult project. One who can describe it specifically and without defensiveness is showing you how they'd handle yours.
The short version
Price and timeline are the questions every builder is prepared for. Draws, subcontractor payment, shell thickness, and what happens when something goes wrong are the ones that reveal how a company actually operates.
