Close the main water valve the moment you find a burst pipe or sewage backup in Lawrenceville. If you smell gas, get out first and call 911 and the City of Lawrenceville gas line at 770-963-3332; homes on Atlanta Gas Light call 877.427.4321. Then call the number on this page to be connected with a local plumber in Lawrenceville.

Calling for help
The number here puts you in touch with an independent plumber who works in Lawrenceville. You will be asked what failed, whether water is still running and where the house is. If gas appliances are involved, say so. Ask about after-hours pricing up front. How quickly someone can come depends on the hour and the plumber's workload, so no arrival time is promised.
What sets the price
- When you call. Nights, weekends and holidays usually carry a premium.
- Access. Pipes behind finished walls or under slabs take more time to reach.
- Scope. A single joint is a small fix; a failed water heater or long pipe run is larger.
- Follow-up permits. The City of Lawrenceville's Building Official sits in Planning and Development; ask the plumber whether the lasting repair needs a permit.
Lawrenceville's utilities
The Gwinnett County seat, known as the Crepe Myrtle City, has an unusual utility setup. Gwinnett County took over the city's water distribution system in December 2020, so water service and billing now come from the Gwinnett County Department of Water Resources. The city kept its wells, storage tanks and treatment plants. For a water or sewer emergency, Gwinnett's 24-hour dispatch number is 678.376.7000.
Gwinnett maintains the water main and the meter. Everything on the customer's side of the meter is the owner's to maintain and repair, and the owner is responsible for the entire sewer lateral, including its connection to the county sewer.
Gas is different. Lawrenceville runs its own natural gas department, and city gas customers report leaks to 770-963-3332 or 911, not Atlanta Gas Light. Parts of the surrounding ZIPs outside the city system may be on Atlanta Gas Light, so check your bill.
The median home was built in 1988 and about 30% predate 1980, so older houses near the downtown square can have tired valves and drain lines.
While you wait
- Keep the main valve closed
- Turn off the water heater if it is leaking
- Cut power to wet rooms at the breaker
- Keep your gas bill handy if a gas appliance is involved
- Note when the problem started and what you saw
