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.

EXCELLENT Based on 56 reviews Sedef Paquette2026-03-04Trustindex verifies that the original source of the review is Google. We had an incredible experience with DMV Waterproofing. On the very first day in our new home, we discovered a flooded basement due to heavy snowmelt. It was incredibly stressful—especially since we were still living out of state and hadn’t even moved in yet. DMV Waterproofing responded quickly and took immediate action. They thoroughly dried the floors and then waterproofed the entire exterior wall with impressive speed and precision. Their attention to detail was outstanding, and they clearly take pride in doing the job right. Throughout the entire process, they were professional, communicative, and dependable. They truly went above and beyond to make sure our home was protected and that we felt reassured, even from a distance. We are extremely grateful for their work and would absolutely recommend DMV Waterproofing to anyone in need of reliable, high-quality waterproofing services.
