If your Lilburn house smells of gas, step outside first, then call 911 and Atlanta Gas Light at 877.427.4321; if your bill comes from the City of Lawrenceville instead, call 770-963-3332. For repairs and new lines on the house side of the meter, call the number on this page to be connected with a local plumber in Lilburn.

Clues your gas piping needs a look
- An odor like spoiled eggs. Get out of the house. Make the calls from outside.
- A faint hiss where the gas line enters the furnace or water heater
- A cooktop flame that has turned lazy and orange
- Dark smudges on the wall behind a gas log set
- Pilot lights that need relighting every few weeks
- A higher gas bill with no change in use
The odor is an emergency. The rest call for a scheduled visit, ideally before the next heating season.
How gas reaches Lilburn homes
The City of Lilburn's natural gas page names Gas South as its partner marketer and points residents to the Public Service Commission's list of other marketers. That is how the Atlanta Gas Light system works: you pick who sells you gas, and AGL delivers it, maintains the pipes and handles leaks. No source ties Lilburn to the City of Lawrenceville gas system, but because Lawrenceville runs its own system nearby, it is worth glancing at your bill to confirm.
Lilburn began as a railroad town in 1890 and is now a diverse southern Gwinnett suburb. Census survey data put the median build year at 1988, with about a quarter of homes built before 1980. That points to a lot of 1980s black iron gas piping, often with appliance connectors that have been in place since the house was new.
The City of Lilburn issues its own permits. Its building permit and compliance inspection application lists plumbing among the M.E.P. trades and includes a utility (power and gas) connect option, which is the route for getting a new or repaired line inspected and released for service.
Cost depends on
- Distance from the meter to the new appliance
- Crawl space, basement or slab construction
- Pipe sizing for the total load in the house
- Replacing old connectors and adding shutoff valves
- Permit, pressure test and inspection
What to expect on the call
Calling the number on this page connects you with an independent plumber who does gas work around Lilburn. Have the appliance model if it is new, and know where your meter is. If the utility has locked the meter after a leak call, the plumber repairs and tests the piping first, then service can be restored.
