What Actually Goes Wrong in Fairfax County Homes

Water damage in Fairfax County is not random. The county's housing stock falls into four rough eras, and each one fails in its own predictable way. Pre-1960 homes in Mantua, Annandale and older Vienna still carry galvanized steel supply lines that corrode from the inside out until a pinhole becomes a split. Homes built roughly between 1978 and 1995, which covers a large share of Burke Centre, Centreville and West Springfield, were often plumbed with polybutylene, and polybutylene fails at the fittings with almost no warning. The 1990s and 2000s townhome clusters through Chantilly, Fair Oaks and Ashburn tend to fail at appliance supply lines and HVAC condensate systems instead. Newer construction is not exempt, it just fails younger and in different places.

Then there is the ground itself. Northern Virginia sits on Piedmont clay, which drains slowly. After a heavy rain the water does not soak away, it stacks up against foundation walls and pushes. That is why a Fairfax basement can flood with no burst pipe anywhere in the house, and why so many finished basements here depend on a sump pump that nobody thinks about until the night it stops.

We work water losses only. Extraction, drying, moisture control, the mold that follows when drying was skipped or done badly, and the repair of what the water ruined. That is the whole scope, and keeping it that narrow is deliberate.
