You can spend weeks researching pool shapes, materials, and features, but none of those decisions will matter if the person you hire to build the pool does not know what they are doing. The in ground pool contractor you choose is the single most consequential decision in your entire pool project. A strong contractor turns a good design into a great pool. A weak one turns a great design into a costly problem.
This blog is a practical, no-nonsense hiring guide for New York homeowners. It covers what an in ground pool contractor actually does, what credentials and questions matter, how to evaluate competing quotes, and what red flags to watch for at every stage of the process.
What an in ground pool contractor actually manages
The term in ground pool contractor covers a broad scope of work. A full-service contractor is not just someone who digs a hole and drops a shell in it. They are a project manager responsible for coordinating multiple trades, obtaining permits, managing a construction timeline, and delivering a finished outdoor environment that meets local building codes and your personal expectations.
The specific responsibilities of an in ground pool contractor include site assessment and soil evaluation, permit applications with your local municipality, excavation and shoring where required, plumbing and hydraulic system installation, electrical rough-in for pumps, heaters, and lighting, shell installation or concrete forming depending on pool type, backfill, coping, and decking, equipment startup and water balancing, and final inspection sign-off.
Not every contractor handles all of these in-house. Some use subcontractors for electrical or concrete work. Understanding which parts of the project your contractor self-performs and which they subcontract out is an important part of the hiring conversation.
Licensing and insurance requirements in New York
New York State requires home improvement contractors to be licensed in the county where work is performed. In Westchester County, for example, a contractor must hold a valid Westchester County Home Improvement Contractor license. Similar requirements apply in Putnam, Dutchess, and Rockland counties.
Beyond licensing, any in ground pool contractor working on your property must carry general liability insurance and workers compensation insurance. General liability protects your property if something is damaged during construction. Workers compensation covers any workers injured on your site. If a contractor cannot produce current certificates for both, do not hire them regardless of how low their quote is.
You should also verify that any subcontractors the contractor uses carry their own coverage. A subcontractor’s injury on your property can become your liability if the primary contractor’s policy does not extend to cover them and the subcontractor carries no insurance of their own.
Questions to ask every in ground pool contractor before hiring
About experience and track record
- How many in ground pools have you installed in this county in the past three years?
- Can you provide references from at least three completed projects similar to mine?
- Do you have photos of completed installations I can review?
- Have you worked on properties with similar soil conditions or site constraints to mine?
About the project itself
- Which parts of this project will you self-perform and which will you subcontract?
- Who will be on-site supervising the work daily?
- What is your realistic timeline from permit application to final inspection?
- What happens if you encounter unexpected site conditions like rock or high water table?
About the contract and warranty
- What does your written contract cover and what is explicitly excluded?
- What warranty do you provide on your workmanship separate from the manufacturer’s warranty?
- What is your process for handling punch-list items after the project is complete?
How to evaluate competing quotes
Getting multiple quotes from different in ground pool contractors is standard practice, but comparing them accurately is harder than it looks. Most homeowners make the mistake of comparing bottom-line numbers without understanding what each number includes.
A detailed quote should itemize excavation, pool shell or concrete materials, plumbing, electrical, equipment such as pump, filter, and heater, coping, decking, permits and inspections, and any landscaping restoration. If one quote is significantly lower than others, the most likely explanation is that something is missing from the scope, not that the contractor is more efficient.
Ask each contractor to walk you through their quote line by line. The quality of that conversation will tell you as much about the contractor as the numbers themselves.

Red flags to watch for during the hiring process
Pressure to sign quickly
A reputable in ground pool contractor will give you adequate time to review a proposal, check references, and ask questions. Any contractor who pressures you to sign a contract within twenty-four hours or claims they can only hold a price for one day is using a sales tactic, not operating with transparency.
Requests for large upfront deposits
It is normal for a contractor to require a deposit before work begins, typically ten to thirty percent of the total project cost. A request for fifty percent or more upfront before permits are even submitted is a red flag. It can indicate cash flow problems or, in the worst cases, a contractor who collects deposits and fails to complete projects.
No written contract
Every in ground pool project should be governed by a detailed written contract that specifies scope, materials, timeline, payment schedule, and warranty terms. A contractor who works on a handshake or provides only a brief one-page agreement is leaving you with no legal recourse if something goes wrong.
Inability to provide references
Any established contractor should be able to provide references from recent comparable projects without hesitation. If a contractor deflects this request, claims clients prefer not to be contacted, or provides references who cannot be independently verified, treat it as a serious warning sign.
Why Coastal Pools and Spas is a different kind of in ground pool contractor
Coastal Pools and Spas has operated as a dedicated in ground pool contractor in Westchester County and the Hudson Valley for over twenty years. We are not a general contractor who builds pools occasionally. Pool construction and backyard transformation is everything we do.
We manage the entire project from initial site assessment through permit applications, excavation, installation, finishing, and final inspection. Every stage is handled by our own team, not passed to subcontractors whose quality we cannot control. We carry full licensing and insurance, provide detailed written contracts, and back every project with clear warranty terms.
We also believe that the best contractor relationship starts with education. Before you hire us, we want you to understand exactly what you are getting, what it costs, and why. That is why our consultation process includes a full 3D design rendering and a line-by-line walkthrough of every quote we provide.
Conclusion
Hiring the right in ground pool contractor is not about finding the lowest quote. It is about finding the contractor who has the credentials, the experience, the processes, and the transparency to deliver your project on time, on budget, and to a standard you will be proud of for decades.
The time you invest in the hiring process, checking licenses, calling references, reading contracts carefully, and asking hard questions, is the most valuable time you will spend in your entire pool project. Coastal Pools and Spas welcomes that scrutiny, because we have built our reputation over twenty years on earning it.
