Basement Waterproofing & Foundation Repair in Manassas, VA
Prince William County sits on expansive clay soil that swells when wet and contracts when dry — putting constant pressure on foundation walls year after year. Many homes in Manassas, Gainesville, and Haymarket were built in the 1970s–1990s with drainage systems that are now aging or undersized. Combined with Northern Virginia’s seasonal rainfall, basement water intrusion is one of the most common problems we see here.
Our Manassas branch is right here in Prince William County. We’ve been inspecting and waterproofing Northern Virginia foundations since 2005.
