Clarksburg's homes are young, with a median build year of 2010, so a leaking service line here is more often a damaged pipe or loose fitting than worn-out material. WSSC Water owns the line up to the property line, and a plumber can repair your portion from there to the house. Call the number on this page to be connected with a local plumber in Clarksburg.

Clarksburg sits at the northern end of the I-270 corridor, about four miles beyond Germantown. Its 18th-century crossroads is now surrounded by new subdivisions, and roughly 84 percent of homes were built between 2000 and 2019. WSSC Water is responsible for the service line from the main to the property line; the homeowner owns everything from the property line into the house. Montgomery County assigns each property a water and sewer category, so some homes on the rural edges may be on a well rather than public water.
Steps to take now
- Shut the main valve where the line enters the house, usually in the basement or a utility closet.
- If water is coming up near the curb, meter or street, call WSSC Water at 301-206-4002; that may be its portion.
- Check whether the wet area is on your side of the property line.
- Think back to recent work in the yard: fences, decks, patios, irrigation or new plantings.
- Keep your builder's paperwork handy if the house is still under any warranty.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Wet spot near a new fence or deck footing | Line punctured during post or footing digging |
| Soggy area close to the foundation | Settled backfill stressing a fitting at the entry |
| Pressure drop after irrigation work | Damaged tie-in or a leaking irrigation supply |
| Meter running with the main closed | Leak on the buried line outside |
| Water in the basement at the pipe entry | Fitting or sleeve problem at the wall |
Cost factors
- How far your portion runs from the property line to the house
- Patios, driveways, retaining walls or new landscaping over the route
- A one-fitting repair versus a new run
- Finished basement space at the entry point
- The WSSC Water permit and inspection required for service line work
Because most Clarksburg lines are young, the pipe material itself is rarely the issue. The plumber will usually focus on where the line was disturbed after construction and repair just that section, leaving the rest in place.
Homes built from 2007 to 2009 may also have a testable backflow assembly on the fire sprinkler system, which WSSC requires to be tested every year; mention it if the plumber will be working near the water entry.
