How to hire a pool contractor without getting burned

A pool is one of the largest projects most people ever hire out, and the trade has its share of operators who take a big deposit and disappear. We build pools, and we would rather you hire a good builder, even a competitor, than get burned by a bad one. Here is how to vet anyone who bids your pool, including us.

Check the license and the bond

In California, pool construction requires a C-53 swimming pool contractor license. Look it up on the state licensing board site by the contractor's license number, not their word. Confirm the license is active, in their company name, and not expired or suspended. Confirm they carry a bond and workers compensation and general liability insurance. If someone is working on your property without workers comp and a worker gets hurt, that can land on you. A real builder hands you these numbers without being asked, because they have nothing to hide and they know you will check.

Understand the payment schedule

California law caps the down payment a contractor can collect at the lesser of ten percent of the contract or a fixed dollar amount. Anyone asking for a third or half up front is either ignorant of the law or counting on you to be. A healthy payment schedule ties money to progress: a small deposit, then payments at excavation, steel, gunite, finish, and completion. You should never be paid far ahead of the work that is actually done. If the money is always running ahead of the dirt, you have lost the one thing that gets the job finished right.

Read the proposal like a contract

A real pool proposal is specific. It names the pool size and depth, the finish, the tile, the coping, the decking, the equipment by model, the fencing, and what is excluded. Vague proposals are how change orders multiply. If the bid says pool, finish, and equipment in three lines with one big number, you do not have enough to compare it to anyone else, and you do not have enough to hold them to. The specificity of the proposal tells you how organized the builder is, and an organized builder is a builder who finishes.

Talk to recent customers and see recent work

Ask for a few jobs they finished in the last year, not their three best photos from five years ago. Drive by or call the owners. Ask the questions that matter: did they finish on the timeline, did the number hold, how did they handle the surprises, would you hire them again. A builder with nothing to hide will gladly point you at recent clients, and the recent part matters, because a company's crew and quality can change fast.

Ask who pulls the permit

A pool requires permits, and the builder should pull them, not push that job onto you. Be wary of any contractor who asks the homeowner to pull the permit, because that is often a sign they are not licensed for the work or they want you holding the liability. The permit also matters because it triggers inspections at the key stages, and those inspections are a free second set of eyes on the steel and the gunite. A builder who treats inspections as a partner rather than an obstacle is a builder doing the work right. Get the permit responsibility in writing, along with who schedules the inspections and who is responsible if the job fails one.

Red flags that should stop you

• A large deposit demand above the legal cap.
• No license number, or a number that does not check out.
• A cash-only discount that skips a written contract.
• Asking the homeowner to pull the permit.
• Pressure to sign today for a price that expires tomorrow.
• A bid far below everyone else, which usually means something got left out.
• No written contract, or a contract with no scope and no schedule.

For the broader checklist that applies to any trade, read questions to ask before you sign. For the money side, the cost-driver breakdown will tell you whether a bid is realistic. More trade guides are at the trade-guide hub.

One reason we built our track record on Quotrr is so a homeowner can see real finished jobs and outcomes that cannot be quietly deleted when they go sideways. You can read how that works on the Props and reviews page and the Quotrr Score page. Hire on proof, not on a sales pitch.
