The City of Stone Mountain doesn't handle sewer; DeKalb County does, and the drains and building sewer on each property are the owner's. With more than half of city homes built before 1980, older pipe is common. Call the number on this page to be connected with a local plumber in Stone Mountain.

What happens when you call
The number connects you with an independent plumber who works in Stone Mountain. You'll describe what's going on: one slow fixture, or several backing up at once, and whether water has come up somewhere unexpected. That decides whether the plumber brings a hand auger or heavier equipment for the main line.
On site, the plumber looks for a cleanout, clears the line with a cable or jetter and runs water to confirm. In older homes, rust flakes or root fibers on the cable are common; a camera inspection is the next step if the line keeps clogging.
What affects the cost
- Distance to the blockage from an access point
- Whether there's an outdoor cleanout; older homes may not have one
- Cable, jetter and camera work, often priced separately
- Repair needs if the pipe is cracked or root-filled
- After-hours and weekend timing
Local conditions
Stone Mountain is a historic village at the western base of the mountain, with a Main Street dating to around 1900, surrounded by much larger unincorporated areas that share the Stone Mountain mailing name. The city's Public Works department doesn't handle water or sewer; it directs those calls to DeKalb County Watershed Management at (770) 270-6243. That's the number when sewage is spilling from a manhole or into the street.
Census survey data put the median home in the city at 1979, with about 52% built before 1980 and roughly two-thirds built between 1960 and 1989. Houses from that era often have cast iron drains that scale and narrow inside and clay or cast iron yard lines that let roots in. Newer homes have plastic pipe, where grease, wipes and hair cause most clogs.
Permits differ by address: inside city limits, Stone Mountain requires separate trade permits and asks residents to contact City Hall before construction, while unincorporated Stone Mountain-mailing addresses go through DeKalb County.
Before the plumber arrives
- Stop using water in the house
- Find the cleanout, if you know where it is
- Clear access to toilets and any floor drain
- Note past clogs or repairs on the line
- Know whether you're inside city limits or unincorporated
