Retaining wall installation
Turn a sloped yard into usable space.
A sloped yard is hard to use and hard to maintain, and a failing wall only gets worse with time. A properly built retaining wall levels out your property, stops erosion and creates room for lawns, patios and planting beds.
Every wall we build starts with excavation, a compacted base and drainage stone and pipe behind it, so water does not push the wall out of place. We can add steps, seating walls and caps that match your patio.
Lawn Brothers Landscaping builds retaining walls for homeowners in Sag Harbor, Glen Cove, Huntington and across Nassau and Suffolk County.
