Foundation Waterproofing in Fairfax, Virginia
Interior and exterior foundation waterproofing to stop recurring groundwater intrusion — the long-term solution after acute flooding has been addressed and dried.
Water damage in Fairfax homes migrates through building assemblies in ways that aren't visible from the surface — inside wall cavities, under flooring, through insulation, and between floors. Foundation Waterproofing begins with mapping the full moisture extent before any extraction or repair begins.
Fairfax's housing stock spans 70 years of construction eras, each with its own plumbing characteristics and failure modes. Galvanized pipes in 1950s–70s homes carry contamination concerns that change the protocol. Polybutylene supply lines in 1980s–90s homes fail differently than copper. We arrive knowing the housing era and adjust our approach before we walk through the door.
What Foundation Waterproofing Typically Costs in Fairfax
Typical range: $5,000 – $20,000 for a major restoration scope in the Fairfax County area. Final cost depends on the specific conditions of your property — we give you a written scope and estimate after the on-site walk-through, with no obligation to proceed.
What affects pricing on a foundation waterproofing job:
- Total square footage and structural involvement
- Whether load-bearing elements need engineering and permits
- Salvage-vs-replace decisions on cabinets, flooring, and finish work
- HVAC, electrical, and plumbing scope alongside structural repair
- Permit timelines from the Fairfax County jurisdiction
About insurance: Major restoration scopes in this range almost always go through insurance. We coordinate directly with your adjuster, provide Xactimate-compatible documentation, and handle the back-and-forth so you don't have to.

We earn our reputation one job at a time. Here's what some of our customers have said.
"Refrigerator water line developed a slow leak behind the cabinets. We didn't see it for weeks. They mapped the moisture, opened just the necessary section of wall, dried it properly, and put it all back better than it was."
Lauren K.Vienna, VA Verified Review"Toilet overflowed on the second floor of our townhouse and dripped through to the kitchen ceiling below. They handled both floors as one job, coordinated with the HOA about the shared wall, and finished in a week."
Marcus D.Reston, VA Verified Review"Hot water heater rusted through in the utility closet on a Sunday morning. They came out the same day, even on a weekend, and had the affected area dried and demoed by Tuesday."
