Lilburn homes on Gwinnett County water own everything past the meter, so a leak in a supply line under the slab is a private repair. A plumber confirms it with a pressure test before opening the floor. Call the number on this page to be connected with a local plumber in Lilburn.

What tends to show up first
- A Gwinnett bill that runs higher than usual for two or more months
- The meter's leak indicator turning with everything off
- Heat underfoot on a tiled floor
- Damp carpet pad or a musty smell in a ground-level room
- A water heater that seems to never rest
Lilburn specifics
Lilburn's water and sewer are provided by Gwinnett County, under an agreement between the county, the Gwinnett County Water and Sewerage Authority and the city. Gwinnett is responsible for the pipes that bring water to the meter, and everything between the meter and the home is the homeowner's.
The housing stock reflects the city's growth since the 1970s. Census survey figures via Point2Homes put the median year built at 1988, with about a quarter of homes built before 1980. Many of the 1970s and 1980s houses around Old Town and along US-29 have copper supply lines that have now been in place for forty years or more.
Gwinnett water is soft, averaging about 1.3 grains per gallon, so scale buildup is not usually what wears out buried pipe. Abrasion and age are more common causes.
The City of Lilburn issues its own building permits, and its application includes plumbing among the trades.
Where the cost comes from
- Finding the leak: isolation, pressure testing, then acoustic or thermal location
- Whether the repair goes through the slab or around it
- Type and extent of flooring to be removed
- Drying and repair of anything soaked
- City permit where needed
Two repair paths are common. A direct repair opens a small section of slab at the leak and splices in new pipe; it suits a single failure in pipe that is otherwise sound. A reroute abandons the buried run and brings new line through walls or the attic; it suits older copper that may fail again. Ask the plumber to explain which fits your house and why.
Before the visit, clear access to the water heater and the main shutoff, and note any spots that feel warm or damp.
Making the call
Calling connects you with an independent plumber who works in Lilburn. Describe the symptoms, say what the meter does with the water off, and note roughly when the house was built. If you see water pooling, close the main shutoff first.
