The City of Stone Mountain doesn't handle water or sewer; DeKalb County Watershed Management does, and the city sends those calls to the county. With about 52% of homes built before 1980, many private laterals in town are aging clay or cast iron. Call the number on this page to be connected with a local plumber in Stone Mountain.

What happens when you call
A call through this page reaches an independent plumber who works in Stone Mountain. Describe the symptoms, how long they've been going on and whether the line has been cleared before. Expect the plumber to restore flow from a cleanout, then camera the lateral to see the pipe material, find cracks, roots or sags and measure depth. Repair options follow from that footage.
If the camera points to the public sewer, or neighbors are backing up too, the city directs water and sewer emergencies to DeKalb County at (770) 270-6243.
What affects cost
- How deep the lateral is and how much of it is damaged
- What's on top: walkways, porches, mature trees or a driveway
- Spot repair, liner or full replacement
- Whether a cleanout must be added
- A City of Stone Mountain plumbing permit; permits are processed for the city by Permit Service Group, and inspections are contracted to SAFEbuilt
Local conditions in Stone Mountain
The city is a historic village at the western base of Stone Mountain, with a preserved Main Street from around 1900. Its housing is older than the surrounding suburbs: the median home dates to about 1979, roughly 52% predate 1980, and about 65% were built between 1960 and 1989. Laterals from those decades are often cast iron or clay. Clay joints separate and let roots in from the old trees in the village, and cast iron corrodes until it cracks.
Stone Mountain mailing ZIPs reach far beyond the small city into unincorporated DeKalb. Sewer there is also DeKalb's, but the city permit office covers only addresses inside city limits; outside them, the county is the likely permit office, though that wasn't verified.
Before the plumber arrives
- Stop running water in the house
- Find the cleanout near the foundation
- Note which drain backed up first
- Contact City Hall before any construction, as the city asks
- Keep pets and children away from any wastewater
If you're buying in the historic village, consider a camera inspection before closing; the condition of a 1960s or 1970s lateral can't be judged from the yard.
