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

Port Washington homes face the Sound — and after a hundred years, the Sound has left its mark on a lot of foundations.

Port Washington sits in North Shore of Nassau County, on clay-over-rock with waterfront sandy fill. Housing stock here is pre-war estates, mid-century waterfront homes, and newer tear-downs — which means the foundations under Port Washington homes face a specific set of problems.

The most common issues we see in Port Washington: waterfront foundation corrosion, hillside drainage, and historic preservation. Our crews know this area inside and out, have worked on homes near Port Washington Harbor, Sands Point Preserve, and carry a transferable lifetime warranty on every repair we perform.
