In Stone Mountain, city Public Works does not handle water or sewer; DeKalb County does, and its responsibility ends at the meter. From the meter to the house, a hidden leak is the owner's, and a plumber can confirm and pinpoint it. Call the number on this page to be connected with a local plumber in Stone Mountain.

What happens when you call
You'll be connected with an independent plumber who works in Stone Mountain. Expect questions about your DeKalb bill, whether the meter moves with everything shut off, and where you have seen stains or soft ground. On the visit, the plumber typically confirms the loss at the meter, closes the main valve at the house to see whether the leak is in the yard or inside, and then works branch by branch with gauges and listening equipment until the source is narrowed to a small spot.
What affects the cost
- Whether original shutoff valves still close, which speeds things up
- Access through a crawl space, slab, basement or finished wall
- Detection equipment needed to avoid broad demolition
- The repair itself, from a valve to a section of service line
- A city plumbing permit inside city limits, processed for Stone Mountain by Permit Service Group with inspections by SAFEbuilt
Stone Mountain conditions
The city is a historic village at the western base of the mountain, with a preserved Main Street from around 1900, surrounded by much larger unincorporated areas that share the Stone Mountain mailing name. Inside the city, about 52% of homes predate 1980, and roughly two-thirds were built between 1960 and 1989. Plumbing that age often has original valves, water heater connections and service lines that have been buried for decades.
The city lists DeKalb County Watershed Management as its water and sewer provider, and directs water and sewer emergencies to DeKalb at (770) 270-6243. DeKalb owns the service line from the main to the meter, including the meter; the property owner is responsible from the meter to the home's plumbing. Commercial and multi-family properties fall under DeKalb's backflow program with yearly testing. Unincorporated Stone Mountain addresses are not covered by the city permit office and generally go to the county.
Before the plumber arrives
- Take two meter readings an hour apart with nothing running
- Make sure the main shutoff turns and is easy to reach
- Clear access to the crawl space door and the water heater
- Photograph any stains to see whether they spread
- Check whether your address is inside city limits, since that decides who issues the permit
