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

Stony Brook blends 300-year-old historic homes with modern university-area development — and we work on all of it.

Stony Brook sits in North Shore of Suffolk County, on North Shore clay with glacial variation. Housing stock here is colonial-era historic homes, university-era 1960s construction, modern builds — which means the foundations under Stony Brook homes face a specific set of problems.

The most common issues we see in Stony Brook: historic home preservation, university-area foundation work, and hillside drainage. Our crews know this area inside and out, have worked on homes near Stony Brook University, Avalon Park & Preserve, and carry a transferable lifetime warranty on every repair we perform.
