A slab leak in Duluth means a water supply pipe under the concrete foundation is losing water, and on Gwinnett County water everything past the meter is the owner's to repair. Many Duluth homes date from the 1980s and 1990s, an age when buried supply lines can start to fail. Call the number on this page to be connected with a local plumber in Duluth.

Is it a slab leak?
- A Gwinnett water bill that keeps rising with no new usage
- The meter shows flow with every tap closed
- A warm or damp patch on a ground-floor room
- Hot water that runs out sooner, or a water heater that cycles often
- Hairline cracks in tile that line up with damp grout
If two or more of these show up together, a proper test is worth the visit; one alone may just be a running toilet.
Duluth conditions
Duluth gets its water from Gwinnett County Department of Water Resources, which treats Lake Lanier water at its Shoal Creek and Lanier plants. Gwinnett maintains the meter and the small pipe from the main to the meter. Everything on the customer's side of the meter, including any line under the slab, belongs to the owner.
Gwinnett water is soft, around 1.3 grains per gallon on average, so hard-water scale is not a big factor in pipe wear here. Slab leaks in Duluth are more often a matter of age and physical wear: pipe vibrating against concrete or stone, or a fitting that has worked loose.
The city's median home dates to 1994 according to Census survey figures via Point2Homes, with large areas of 1980s and 1990s housing. Those homes are now thirty to forty years old.
One local detail stands out: the City of Duluth's inspection list includes a slab plumbing inspection, checked before concrete is poured on new work. When a plumber reroutes or repairs a line, Duluth Community Development handles the trade permit through its GovWell portal.
What affects the cost
- Detection time, from meter checks to pressure, acoustic and thermal testing
- The repair path: a spot repair through the slab, or a reroute overhead
- How much flooring has to be removed and replaced
- Drying out and repairing water damage
- The trade permit and inspection, if required
