If you smell gas in a Forest Park home, leave immediately and call 911 and Atlanta Gas Light at 877.427.4321 from outside; gas marketers do not handle leaks. Leak repairs past the meter, new appliance lines and pressure tests are plumber work, so call the number on this page to be connected with a local plumber in Forest Park.

Old houses, old gas pipe
Forest Park is an inner-ring Clayton County suburb that grew up as a railroad stop and now includes the former Fort Gillem. It has one of the oldest housing stocks covered on this site: Census survey figures put the median build year at 1965, and close to 78% of homes were built before 1980. In practice that means gas systems with black iron pipe that has been in the ground and crawl spaces for decades, shutoff valves that are hard to turn, and connectors that predate modern coated flex lines.
Clayton County tells residents to pick a state-certified gas marketer, which is how the Atlanta Gas Light system works, and no Clayton County city appears on the Municipal Gas Authority of Georgia coverage map. AGL owns the pipes and meters and takes leak calls; the marketer only bills you.
The City of Forest Park requires a city permit for plumbing installation work, with applications filed through its OpenGov portal and inspections requested by email.
Fix the fitting or redo the run?
| What the plumber finds | Likely recommendation |
|---|---|
| A single weeping union or valve | Replace that fitting, then pressure test |
| Old uncoated brass connector | Swap for a new listed connector |
| Rusted pipe at the foundation or in damp crawl space | Replace the corroded section |
| Multiple leaks on a full test | Replace larger portions of the system |
| Branch too small for a new appliance | Run a new, properly sized branch |
Signs to watch for
- Rotten-egg smell. Leave the house; call from outside.
- A hiss in the crawl space or behind an appliance
- Yellow or flickering flames
- Soot around a furnace or water heater
- A pilot that keeps going out
- Rust flaking from pipe near the meter
Timing
In homes this age, problems often show up when the heat comes on for the first time in fall, or right after an appliance is moved for a floor or kitchen project. Getting a pressure test before winter, or whenever an old appliance is replaced, catches slow leaks while they are still small. If AGL shuts the meter off after a leak call, plan for the repair and retest before service is restored.
