If a Dunwoody home smells of gas, leave first, call 911 from a safe place and then Atlanta Gas Light at 877.427.4321. Repairs and new lines on your side of the meter are plumber work, so call the number on this page to be connected with a local plumber in Dunwoody.

The City of Dunwoody lists Atlanta Gas Light as its gas utility; customers buy gas from certificated marketers. Dunwoody's established neighborhoods around Dunwoody Village are older than its Perimeter Center towers suggest. Census survey data put the median build year at 1984, with about 44% of homes built before 1980, so many houses have black iron gas piping that has been extended for newer appliances.
What to do right now
- Odor of gas? Leave the house without operating switches or appliances.
- Call 911 from a safe place, then Atlanta Gas Light at 877.427.4321.
- Let AGL clear the house. If the leak is on your piping, the meter may stay off until repaired.
- Call a plumber. They find and fix the leak and pressure test the system.
- Permit first. Dunwoody issues single-trade permits for stand-alone jobs like water heater replacements, and work may not begin until the permit is issued.

Calling for help
The number on this page connects you with an independent plumber who works on gas piping in Dunwoody. Have a list of your gas appliances and note where the meter is. First-time contractors in Dunwoody must provide license and business paperwork before the city issues a permit, so give the plumber a little lead time for planned jobs. For an active leak, the safety steps above come first; paperwork follows once the house is safe. A full-system pressure test is often the right first step in a home from the 1970s or early 1980s. Ask the plumber to label shutoff valves while they are there.
