The City of Stone Mountain lists DeKalb County Watershed Management as its water and sewer provider, and DeKalb owns the service line from the main through the meter. From the meter to the home's plumbing, the line is the owner's responsibility. Call the number on this page to be connected with a local plumber in Stone Mountain.
What happens on the call
This is a referral service, not a plumbing company. It connects you with an independent local plumber who works in Stone Mountain. They'll ask where water is surfacing, whether pressure is down everywhere and whether the meter moves with the house shut down. On site, the plumber confirms the leak, finds where the line enters the house, traces the route and digs to the break. You'll hear whether a splice will hold or the line should be replaced.
What affects the cost
- Pipe age. Most city homes are from 1960 to 1989, and older lines may need replacing.
- Terrain. Granite close to the surface near the mountain can slow excavation.
- Surface. Old walks, porches and trees on village lots.
- Method. Spot repair, trench or bore.
- Permit. The city requires separate trade permits, including a plumbing permit, processed for the city by Permit Service Group with inspections by SAFEbuilt.
Stone Mountain conditions
The city is a historic village at the western base of Stone Mountain, with a Main Street dating from around 1900. City Public Works doesn't handle water or sewer; those calls go to DeKalb at 770-270-6243. DeKalb's ownership sheet puts the dividing point at the meter, with the owner responsible from the meter to the home's plumbing.
Housing in the city skews older: the median home was built in 1979, about 52% predate 1980, and roughly two-thirds were built between 1960 and 1989. Lines that age may be galvanized or patched. DeKalb keeps a "Check your line" service line inventory, and its 2026 report advises extra flushing for homes with lead or galvanized service lines.
Stone Mountain-mailing ZIPs cover large unincorporated areas beyond the city. Those homes still get DeKalb water, but their permits come from DeKalb County rather than the city. Village lots are often small with old stone walls and walkways, so ask whether a bored line would spare them.
