Lawrenceville runs its own gas department, so if you smell gas, leave first and call 911 or the City of Lawrenceville gas line at 770-963-3332 from outside; addresses on Atlanta Gas Light call 877.427.4321. Repairs and new lines past the meter are plumber work, so call the number on this page to be connected with a local plumber in Lawrenceville.

What happens when you call
The number on this page connects you with an independent plumber who does gas work in the Lawrenceville area. The first question is usually which gas utility is on your bill, because meter work and service restoration go through that utility. Then the plumber asks about the appliance, the meter location and any leak the utility has already found.
The plumber's work stops at the meter on either system. Anything upstream, including the meter itself, the service line and the street main, belongs to the utility, so a larger meter for a generator or a tankless heater is arranged with the city gas department or AGL. Downstream, the plumber runs, repairs and tests the piping, and the inspection confirms the work before gas is turned back on. If you are moving into an older Lawrenceville house, a pressure test of the whole system is a reasonable first step before adding anything new.
What affects cost
- Run length and the number of fittings and valves
- Upsizing a trunk line for added appliances
- Basement, crawl space or slab access
- Outdoor lines for grills or generators
- Permit and inspection requirements
Lawrenceville conditions
Lawrenceville is the Gwinnett County seat, known for its historic courthouse square and Georgia Gwinnett College. The city runs its own Natural Gas Department on West Pike Street, and Georgia 811 lists the City of Lawrenceville as a Gwinnett gas operator. City gas customers report leaks to 770-963-3332 or 911, not to Atlanta Gas Light. The system's boundary was not published, and parts of the surrounding ZIP codes may be on AGL instead. Your bill settles it:
- City of Lawrenceville gas: 770-963-3332
- Atlanta Gas Light: 877.427.4321
Census survey data put Lawrenceville's median build year at 1988, with about 30% of homes built before 1980. That means a mix of older black iron systems and newer flexible tubing. The city's Building Official sits within Planning & Development; specific gas permit rules were not confirmed, so the plumber will check what applies.
Before the plumber comes
- Find your gas bill and note the utility
- Clear access to the meter and appliance
- Have the appliance model number ready
- Note whether the meter has been locked or tagged
- If you smell gas again, leave and call 911
