A slab leak in Oxon Hill is a water supply line leaking under a concrete floor, common in townhouses, garden apartments and homes with basements. WSSC Water owns the service line to the property line, and from there the pipe is the owner's to repair. Call the number on this page to be connected with a local plumber in Oxon Hill.
When you call
The number connects you with an independent plumber who covers Oxon Hill. Share what you noticed: a meter that keeps moving, a warm patch on the floor, a water bill that jumped, or damp carpet. The plumber will usually start by confirming there is a leak at all, then split the system into hot and cold and pressure test each side. From there, acoustic listening and thermal imaging help pinpoint the leak so only a small section of floor needs opening, if any.
What changes the cost
- How quickly the leak is pinpointed. A hot-side leak usually shows up faster on a thermal camera than a cold one.
- Type of building. In a townhouse or condo, shared walls and floors can limit reroute paths and may involve an association.
- Spot repair or reroute. Fixing one point under the slab versus running new pipe through walls or the ceiling.
- Floor and wall restoration. Tile, vinyl plank and finished basements each add different repair work.
- Permit. WSSC Water permits and inspects plumbing work in Prince George's County.
Local conditions
Oxon Hill sits along the Potomac just southeast of Washington, next to National Harbor, and mixes garden apartments, townhouses and single-family homes. The median home was built around 1972, so a lot of plumbing here is original or close to it. Pipe of that age buried under a slab or basement floor has had half a century of settling, temperature swings and contact with stone. Some customer-side service lines from that period are galvanized, and WSSC's What's Your Pipe Type? map lets you look up the recorded material at your address.
If the leak looks like it is outside, such as water pooling near the curb or the meter, call WSSC Water's emergency line at 301-206-4002 first. WSSC also requires a plumber holding its license for water service line repairs and interior re-piping, so a reroute is a job for a pro rather than a weekend project.
Checklist before the visit
- Run a meter test and note the result
- Locate the main shutoff valve
- Clear the area over any warm or damp spot
- Check with your association if you are in a townhouse or condo
- Take photos of any damage
