Legacy Custom Pools is a Long Island pool builder doing things the old way: same crew on every phase, real certifications, and a pool that holds up long after the warranty period ends.
Whether you are starting from a bare backyard or bringing a tired pool back to life, we handle the full lifecycle — design, build, renovation, and weekly care — without subcontracting the crews you depend on.
New pool builds. Custom gunite construction with 3D rendering, steel-reinforced framework, and finishes from polished aggregate to natural stone. Vinyl liner builds with full pattern selection and integrated features like sun shelves, stadium steps, and tanning ledges.
Renovations. Marble dust resurfacing, liner replacement, equipment upgrades, structural repairs, and full backyard redesigns. We bring 20-year-old pools back to better than new.
Service and maintenance. Weekly maintenance, spring openings, fall closings, leak detection, and emergency repair. The same crew that builds the pool stays connected to it for the long run.
WHY LEGACY
No subcontracted gunite team, no separate plumbing company, no rotating cast of installers. The person responsible for your project is on-site from excavation to final walkthrough.
Industry-recognized standard for pool design, code compliance, structural integrity, and finish quality. Not a vendor sticker — a real certification.
We handle weekly maintenance, openings, closings, and equipment service after the build. The crew that built your pool knows what is behind the wall ten years from now.
Most pool builders are coordinators. They quote your project, sub it out to four different crews, and hope nothing gets dropped between the design rendering and the day you swim. We do not work that way. The same team that designs your pool is on-site every phase of the build — excavation, steel, gunite, plumbing, finish, and final start-up.
That continuity is why our pools hold up. A Pool & Hot Tub Alliance Certified Building Professional credential is not decoration on the website. It means the person responsible for your build is held to the industry-recognized standard for design, code compliance, and finish quality. You do not get re-introduced to a new face every time something needs answering.
And because we also handle ongoing service after the build — openings, closings, weekly care, and equipment upgrades — the relationship does not end at your final walkthrough. The crew that built your pool is the crew that knows what is behind the wall when the heater needs work five years from now.

Legacy Custom Pools serves homeowners across Long Island — from the North Shore Gold Coast villages, through Smithtown and the central Suffolk townships, down to the South Shore beach communities and east into the Hamptons. We know the soil conditions, the freeze-thaw cycles, and the town-by-town permitting requirements that affect every Long Island pool project.
Whether you are in Huntington, Smithtown, Babylon, Brookhaven, Islip, Sayville, Bay Shore, Patchogue, Riverhead, Southampton, East Hampton, Port Jefferson, Stony Brook, Northport, Hempstead, Oyster Bay, Garden City, Massapequa, Manhasset, or any town between — give us a call.
RECENT PROJECT · LONG ISLAND
Every Legacy project is photographed and documented at completion. Our crews stand behind the work — and you can see it in the finishes, the coping work, the equipment-pad layout, and the integration between pool and hardscape. No stock photos on this site.
Pool builders who do not understand Long Island design pools that do not fit Long Island yards. We have built across every micro-climate the island has — North Shore clay, South Shore sand, exposed Hamptons coastal lots, and tree-shaded inland parcels. Every condition needs different decisions about drainage, freeze protection, finish choice, and equipment selection.
The right pool for your yard depends on more than your budget. It depends on how you actually use the backyard — who is swimming, how often, whether you entertain, whether you want a year-round spa or a summer-only pool, how the kids will grow into and out of it. We design around that first, then size the project to the budget.

Are you a certified pool builder?
Yes — Legacy holds a Pool & Hot Tub Alliance Certified Building Professional credential, the industry-recognized standard for pool design, code compliance, and finish quality. We are also fully licensed and insured for pool construction in New York State.
Call 631-618-5111 or fill out the contact form. We respond to every inquiry within 48 hours, and an on-site consultation for new builds and renovations is always free.
Do you handle both gunite and vinyl liner pools?
Yes, we build both. Gunite gives you the most durable and customizable pool with a 50+ year shell lifespan. Vinyl liner pools are faster and more affordable upfront, with the liner needing replacement every 8-12 years. We walk through both options with real numbers during your consultation.
Do you service pools you did not build?
Yes — most of our weekly maintenance and renovation clients have pools built by other companies. You do not need to have been a previous customer for us to take on your service or renovation.
How long does a pool project take?
Gunite builds typically run 8-12 weeks weather permitting. Vinyl builds run 4-6 weeks. Renovations run 3-6 weeks. We give you a realistic timeline in your contract and update you weekly.
Yes, we work with financing partners that handle both new builds and renovation projects. We walk you through options during the quote conversation.
