If gas is smelled in a Riverdale home, leave and call 911 and Atlanta Gas Light at 877.427.4321 from outside. Fixing leaks past the meter, adding appliance lines and testing piping are jobs for a plumber, so call the number on this page to be connected with a local plumber in Riverdale.

Gas warning signs
- Rotten-egg smell. It means leave, not investigate.
- Hissing around the stove, dryer or water heater connection
- Flames that are mostly yellow
- Soot on vent pipes or nearby walls
- A burner that won't light evenly
- Dead grass along a buried line
The smell is the emergency. The others are reasons to schedule a plumber.
Riverdale's gas and housing
Riverdale is a western Clayton County city just south of Hartsfield-Jackson, founded as a railroad stop in 1886. Clayton County directs natural gas customers to pick a state-certified marketer, which is how the Atlanta Gas Light system works, and no Clayton County city shows up on the Municipal Gas Authority of Georgia's coverage map. AGL owns the pipes, so leaks go to AGL rather than the company that bills you.
Census survey data put the median build year at 1990, with about a third of homes built before 1980. Older houses can have black iron pipe extended over the years, while newer ones may have flexible tubing. Either way, adding a gas appliance means checking that the existing pipe can supply it.
The City of Riverdale's Community Development department handles permits, and its Trade Permit Application covers plumbing. Gas piping tied into a new water heater, furnace or range is normally permitted and pressure tested so the inspector can confirm the joints hold.
On any lot, a buried gas line can be nicked by later projects such as fence posts or patio footings. If a line runs across the yard, call Georgia 811 before digging anything new.
What affects the cost
- Run length and the number of turns and fittings
- Access through crawl space, slab or finished walls
- Pipe sizing for the total appliance load
- Any outdoor or buried section
- Permit and inspection
What happens on the call
The number on this page connects you with an independent local plumber who handles gas piping around Riverdale. Describe the appliance, the meter location and whether AGL has tagged or shut off any part of the system. A plumber can then explain whether the job needs a city permit and a pressure test before service is restored.
If you are unsure whether a smell is gas or something else, treat it as gas. It costs nothing to step outside and let the utility check, and a plumber can follow up once it is safe.
