Pool Installation in Smithtown, Suffolk County

Why Smithtown Homeowners Choose Us

Smithtown lots average around half an acre, which gives most homeowners real flexibility in pool placement — but the soil here skews toward heavy clay, especially in older neighborhoods. Clay soil retains water, which can complicate excavation and drainage if it isn't accounted for in the design phase. Our engineers evaluate every site individually, and where clay is present we spec proper drainage solutions including French drains and gravel backfill to protect the shell long-term. Setback requirements under Town of Smithtown building code typically require pools to be placed at least ten feet from rear property lines and five feet from side lot lines, which our design team maps out before a shovel hits the ground.

Popular Pool Types in Smithtown

Concrete and fiberglass are the two pool types we install most often in Smithtown. Concrete is popular with homeowners on larger lots who want a custom shape — the extra square footage makes it easy to accommodate a full-size rectangle or a freeform design with an integrated spa. Fiberglass is the go-to for homeowners who want a faster installation window and lower lifetime maintenance costs, particularly attractive given how much seasonal use Smithtown pools get. Vinyl liner pools are less common here but remain a solid budget-conscious option on tighter sites.

Pool Permits in Smithtown

All pool installations in Smithtown require permits through the Town of Smithtown Building Department, located at 99 West Main Street. You'll need a completed pool permit application, a current property survey stamped by a licensed surveyor, and a site plan showing pool placement, setbacks, and fencing. The building department also requires NYS-compliant barrier fencing details as part of the submission. Approval timelines run roughly three to six weeks during the spring season and can stretch longer in summer when volume is high. Long Island Pool Pros manages the entire permit package and communicates directly with the building department throughout the process.

Pool Installation Cost in Smithtown

Pool installation in Smithtown typically ranges from $55,000 to $160,000 depending on pool type, size, and the scope of the surrounding patio work. Fiberglass pools on a standard Smithtown lot generally fall between $60,000 and $90,000 installed. Concrete pools start around $80,000 and climb quickly with custom shapes, integrated spas, or premium coping and decking materials. If your soil survey reveals significant clay content, budget an additional $3,000 to $6,000 for drainage improvements — an investment that protects the structure for decades and avoids costly repairs down the road.
