A gas smell in a South Fulton home means everyone goes outside, then someone calls 911 and Atlanta Gas Light at 877.427.4321 from a safe distance. For new appliance lines, leak repairs on your side of the meter and pressure tests, call the number on this page to be connected with a local plumber in South Fulton.

Gas service in a young city
The City of South Fulton was incorporated in 2017 from formerly unincorporated communities such as Cliftondale, Sandtown, Red Oak and Welcome All. It has no gas department of its own. Fulton County's development authority states that Atlanta Gas Light maintains the area's natural gas infrastructure, and residents buy gas from competing marketers. Whoever bills you, AGL owns the mains and meter and is the company to call about a leak.
Plumbing permits here come from the City of South Fulton, not Fulton County. The city's permitting department processes trade and MEP (mechanical, electrical, plumbing) applications from City Hall on Fulton Industrial Boulevard. Gas piping added for a new water heater, range or dryer generally goes through that process, with a pressure test before the line is put into service.

|---|---|
| Gas smell, hissing, or a damaged meter | 911 and Atlanta Gas Light, from outside |

Signs to act on
- A rotten-egg odor. Leave first and call from outside.
- A hiss at a connector or valve
- Flames burning yellow instead of blue
- Soot on an appliance cabinet or flue
- Pilot lights that keep dropping out
- Yard spots where grass dies along a straight line
Timing and seasons
Late fall is when many South Fulton households fire up gas furnaces and fireplaces for the first time in months, and it is when small leaks and dirty burners become obvious. Booking connector swaps, a new branch for a fireplace or a check of older piping in late summer or early fall avoids the rush. Outdoor kitchen and grill lines are easier to trench in dry weather. If an appliance is being replaced anyway, that is the best moment to replace an aging flex connector and add a shutoff valve where one is missing.
