How to Choose a Pool Builder Without Getting Burned
How to choose a pool builder: verify the license and insurance yourself, demand real local references you can actually visit, and sign a contract that ties payment to construction milestones with no large upfront deposit. Everything else is detail. Those three things separate the builders who finish from the ones who leave a half-dug hole in your yard.
I've built inground pools for 17 years, and I've also been the guy homeowners call to finish a job some other outfit abandoned. I've stood in a backyard in March looking at a flooded, half-excavated pit, talking to a couple who paid a $35,000 deposit to a builder who stopped answering the phone. That conversation is why I wrote this. You're about to hand someone tens of thousands of dollars to dig a permanent hole in your property. Vet them like it.
Start With License and Insurance, and Verify It Yourself
Anyone can say they're licensed and insured. Your job is to confirm it without taking their word.
- License. Most states license pool or general contractors. Look your builder up on the state licensing board's website yourself. Confirm the license is active, in the company's name, and free of major disciplinary actions. If your state doesn't license pool builders specifically, check the general contractor and electrical requirements.
- General liability insurance. Ask for a certificate of insurance, then call the insurance agent listed on it to confirm it's current. A real builder hands this over without flinching.
- Workers' compensation. If their crew gets hurt in your yard and they don't carry comp, you can end up liable. Confirm it.
This takes an afternoon. It's the cheapest afternoon of the whole project.
Demand Real, Local, Recent References
Online reviews are a starting point, not proof. Anyone can buy reviews or post their own. What you want is to talk to and ideally visit real customers.
Ask for three references whose pools were built in the last two years, in your area, in the type of pool you want. Then actually contact them and ask:
- Did the project finish on the timeline they put in writing?
- Did the final price match the contract, or were there surprise change orders?
- How did the builder handle problems, because every job has at least one?
- Would you hire them again?
If you can, drive by or visit a finished pool. A builder who's proud of their work will happily set this up. One who dodges, stalls, or only offers references from five years ago is telling you something.
You can also start from a vetted list. Our pool builder directory shows service areas and pool types up front, which saves you the first round of phone tag.
The Contract Is Where You Win or Lose
A handshake and a glossy render is not a contract. Before any money changes hands, you want a detailed written agreement. Here's what it must spell out.
A milestone payment schedule, never a big upfront deposit
This is the single most important thing in this article, so I'm putting it in bold. Do not pay a large deposit before work begins. A reasonable deposit to get on the schedule and order materials is small, often 5 to 10 percent. After that, payment should be tied to completed construction milestones, and you pay for each stage only after it's done and you've seen it.
A healthy schedule looks something like this:
| Stage | Typical payment | What's done |
|---|---|---|
| Signing / scheduling | 5% to 10% | Permits filed, materials ordered |
| Excavation complete | ~15% | Hole dug to spec |
| Steel and plumbing rough-in | ~20% | Cage set, lines run and pressure-tested |
| Gunite / shell set | ~25% | Structure in place |
| Decking and coping | ~15% | Deck poured, coping set |
| Plaster / interior finish | ~10% | Surface done |
| Final / startup | ~5% | Filled, balanced, inspected, walkthrough |
The exact percentages vary, but the principle doesn't: the money should always slightly lag the work, so the builder is never paid for a stage they haven't finished. A builder who demands 50 percent or more upfront is either undercapitalized, using your money to finish someone else's job, or planning to disappear. Walk away. That's the deposit-and-vanish setup, and I've seen it end the same way too many times.
Who pulls the permits
The contract should state, in writing, that the builder pulls all permits in their name. If a builder asks you to pull an owner-builder permit, be very careful. It often means they can't, because their license won't support it, and it shifts liability for code violations onto you. The party who pulls the permit is the party the inspector holds responsible. You want that to be the professional, not you.
Timeline in writing, with what happens if it slips
Get start and substantial-completion dates in the contract. Weather and rock cause honest delays, and a fair builder will explain that, but the document should still commit to dates and describe how delays get communicated. Vague "we'll get to it" timelines are how a pool sits open through a season.
Lien releases
This one protects you from a debt you didn't know you had. If your builder doesn't pay their subcontractors or suppliers, those parties can put a mechanic's lien on your house even though you paid the builder in full. Protect yourself by requiring lien waivers or releases from the builder and major subs at each payment. Your title can be clouded by a supplier you never met. Lien releases are how you shut that door.
Subs vs In-House, and Why It Matters
Almost every pool builder uses subcontractors for some trades, electrical and gas especially. That's normal and fine. What you want to know is who's doing what and whether the key people are reliable.
Ask which trades are in-house and which are subbed, and whether the subs are regulars or whoever's available that week. A crew that's worked together for years catches problems a rotating cast of strangers misses. There's no single right answer here, but a builder who can clearly tell you who's bonding the pool's electrical and who's setting the steel is a builder who's actually managing the job.
Get Everything in Writing, and Document the Build
Once you've hired, keep protecting yourself. Photograph each stage. Keep every change order in writing and signed by both of you before the work happens. A change order discussed verbally and "we'll sort it out later" is how a budget quietly grows by $15,000.
A simple phone is enough for most of this, but if you want a clean record of the deeper construction stages, an inspection borescope camera lets you actually see plumbing connections and tight spots before they get buried. You're documenting the parts you can't inspect once concrete covers them.
The Red Flags That Should End the Conversation
After 17 years, these are the warnings I'd run from:
- Demands a large upfront deposit or "needs the money to buy materials" before any work. The biggest one.
- No verifiable license or insurance, or gets cagey when you ask to confirm it.
- Pressure and urgency. "This price is only good today" is a sales tactic, not a construction reality.
- No written contract, or a one-page agreement with no payment schedule or timeline.
- Asks you to pull the permit.
- Cash-only or wants checks made out to a personal name rather than the business.
- References that are all old, all out of town, or unavailable.
- A quote dramatically lower than everyone else's. Either they're missing scope they'll surprise you with later, or they can't actually deliver at that price and will run out of money mid-build. The cheapest quote is how a lot of half-dug holes start.
What This Means for You
Choosing a pool builder isn't about who has the slickest render or the lowest number. It's about who's licensed, insured, referenced, and willing to put a milestone payment schedule in writing. Verify everything yourself, pay for work only after it's done, and never let a stranger hold a big chunk of your money before the digging starts.
Do that and the horror stories simply can't happen to you. Get three line-item quotes, vet all three the way I've described, and pick the one who answers your hard questions without flinching, not the one who's cheapest. You can browse vetted builders in our directory to start your shortlist, and if you're a builder who runs an honest milestone schedule, get listed so the homeowners doing this homework can find you.
