Slab leak repair in Atlanta

A slab leak is a leak in a pipe below a concrete floor. Because you can't see it, the water meter and the bill are often the first clues.

Last reviewed November 13, 2026

Short answerRun the water meter test. If the meter moves with everything off and you've ruled out toilets and irrigation, ask for leak detection before any concrete is opened.

Checking for a hidden leak

EPA WaterSense suggests reading the meter before and after two hours with no water use; any change probably means a leak (EPA WaterSense). Rule out toilets with a dye test first (EPA WaterSense). See the water meter check.

Finding it

Atlanta Watershed Management says not all leaks leave visible or audible evidence, plumbers often can't find them, and a specialized leak detection company may be needed (Atlanta Watershed Management). See leak detection in Atlanta.

Permits

Atlanta's plumbing permit form lists altering piping beneath a floor, and emergency repair of leaking concealed piping when new piping exceeds 5 feet (City of Atlanta). Ask whether the plan is to repair under the slab or reroute the line.

Insurance

Washington's insurance commissioner uses a leaky pipe under the floor as an example of a gradual leak most policies don't cover (Washington OIC). Ask your agent how your policy treats slab leaks before work begins.

Checking the plumber

Georgia licenses plumbers through the Secretary of State. The state does not register plumbing companies, and only licensed master plumbers may run a plumbing business (Georgia Secretary of State). A Class I master plumber license covers single-family homes and one-level homes for up to two families; Class II has no restrictions (Georgia Secretary of State). Ask for the master plumber's name and check it in the state's licensee search.

Common questions

Can I get the leaked water credited?

Atlanta may adjust bills for some customer-side leaks with proof of repair (Atlanta Watershed Management). See leak adjustments.
