First, in Fairfax
From 2016 to 2025, Fairfax County logged 97 days with flash flood or flood reports. The City of Fairfax has older housing than the county around it. Census figures show 68% of homes in the city were built before 1980, against 44% for the county. In those homes the main shutoff is usually in the basement near the front wall, often an older gate valve. When water appears, close it slowly and fully, or close the valve at the fixture if the leak is there.
Then switch off the breakers for wet rooms and the basement if water reaches outlets, the furnace or the water heater. Photograph the source, the water on the floor and every damaged item before cleanup. Lift boxes, rugs and stored items off the basement floor. In a Fairfax basement, keep the furnace and water heater circuits off until the floor is dry.
Speed matters because water wicks up drywall and carpet pad holds it against the slab. According to the EPA, wet materials should be dried within 24 to 48 hours. Cold adds risk here, with NOAA climate normals showing 99 nights a year at or below 32 degrees, more than the county's 92. With 26% of homes in buildings of 5 or more units, condo owners should also tell the manager and the unit below. Sewage cleanup or clean water drying can begin once the source is stopped anywhere in the Fairfax area.
Before the crew arrives
Do these in order, and only what is safe to do.
- Shut off the water at the main valve or the fixture valve.
- Turn off power to wet rooms at the breaker if you can reach it without stepping in water.
- Photograph every wet room, the source and the water line.
- Lift furniture off wet carpet and move papers, photos and electronics to a dry room.
- Call (833) 728-2327 for extraction and drying, and tell your insurer.
- Keep people and pets away from sewage or floodwater.

What Fairfax homes add to the list
Older houses set the pattern for water damage in Fairfax. With 68% of homes built before 1980, many have copper supply lines, older water heaters and basement floor drains tied to aging sewer laterals. A pinhole leak in old copper can wet a finished basement wall for weeks before it shows. If you see a stain or smell mustiness, close the main shutoff and look along the ceiling of the basement.
Winter is the next factor. NOAA climate normals show 99 nights a year at or below 32 degrees and 23 nights at or below 20. Add 13 days that stay below freezing and 19 inches of snow. Pipes in exterior walls, garages and crawl spaces freeze first, and snowmelt can seep into basements through window wells.
Storm water is the third. Fairfax County had 97 days with flash flood or flood reports between 2016 and 2025. Since 2000, it has had 8 major disaster declarations for floods and storms. FEMA flood insurance records put the average building payment on a county flood claim at $21,419. Only 1.1% of county homes carry federal flood insurance. Homeowners policies usually exclude outside flood water, so check yours before cleanup. Basements needing water removal in Centreville face the same storms. Condo owners who need water removal in Reston should start with the building manager.
What to leave alone until help arrives
In the first hours, avoid three common mistakes. One: stepping into water near electricity, or standing under a wet ceiling. Two: trying to dry the house with heat or a household vacuum, which spreads moisture and can damage the machine. Three: throwing things away or covering stains before the damage is recorded. Photograph first, keep wet walls open, and let the moisture readings decide when repairs can start in your Fairfax home. Water removal from carpet saves the most when the water was clean and caught early; the pad usually comes out.
