Shut off the main water valve right away when a pipe bursts or sewage backs up in Stone Mountain. If you smell gas, leave and call 911 and Atlanta Gas Light at 877.427.4321 from outside. Then call the number on this page to be connected with a local plumber in Stone Mountain.

What the call involves
You will be put through to an independent plumber who works in Stone Mountain. Describe what broke, say whether the water is off and give the address. Let them know whether you are in the city itself or the wider Stone Mountain mailing area. Ask about after-hours rates first. Arrival depends on the time and the plumber's schedule, so no time is promised.
Cost factors
- Timing. Night and weekend work usually costs more.
- Older materials. Galvanized or cast iron pipe may need replacing, not patching.
- Access. Crawl spaces and older plaster walls slow the work.
- Permits. The city requires separate trade permits, including a plumbing permit, processed by Permit Service Group for the city with inspections by SAFEbuilt. Unincorporated addresses fall to the county.
Stone Mountain conditions
The historic village sits at the western base of Stone Mountain, with a preserved Main Street dating from around 1900. About 52% of homes in the city were built before 1980, and about 65% were built between 1960 and 1989. In houses from those decades, original water heaters, galvanized branch lines, cast iron drains and aging shutoff valves are common sources of a sudden leak or backup.
The city's Public Works does not handle water or sewer. DeKalb County Watershed Management provides both, and the city 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.
The Stone Mountain mailing ZIPs cover large unincorporated areas beyond the city, where county rules apply to permits. Water and sewer there are still DeKalb County's, so the emergency number is the same. In older houses, test the main valve now and then; one that has not moved in years may not close when you need it, and the plumber can replace it with a quarter-turn valve during a repair.
Before the plumber arrives
- Main valve off; if it is stuck, close the water at the meter pit
- Water heater shut down if it is leaking
- Breakers off for wet rooms
- No water use during a sewer backup
- Access cleared to the crawl space or basement
