Foundation Work in Islip
Every home has a story. Every soil type has a solution.

Living close to the Great South Bay means living with water — which means your foundation has to work harder than most.

Islip sits in South Shore of Suffolk County, on sandy, with high water table proximity to the Great South Bay. Housing stock here is post-WWII ranches and Capes alongside newer waterfront construction — which means the foundations under Islip homes face a specific set of problems.

The most common issues we see in Islip: hydrostatic pressure from the high water table, basement flooding during nor'easters, and sagging crawl spaces in older homes. Our crews know this area inside and out, have worked on homes near MacArthur Airport, Heckscher State Park, the Great South Bay, and carry a transferable lifetime warranty on every repair we perform.
