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

From the Gold Coast mansions to the bayfront cottages, Oyster Bay has foundation challenges that go back a century.

Oyster Bay sits in North Shore of Nassau County, on dense clay with rocky outcroppings, typical of Gold Coast terrain. Housing stock here is historic mansions and estates, mid-century suburban builds, and newer luxury homes — which means the foundations under Oyster Bay homes face a specific set of problems.

The most common issues we see in Oyster Bay: stone and field-stone foundations in historic homes, water intrusion from hillside drainage, and aging basement waterproofing. Our crews know this area inside and out, have worked on homes near Planting Fields Arboretum, Sagamore Hill, Jericho Turnpike corridor, and carry a transferable lifetime warranty on every repair we perform.
