A slab leak is a water leak in plumbing pipes located beneath a building's concrete foundation slab. Common causes are aging or corroded pipes, shifting soil, poor installation, and physical damage. Common signs include unexplained high water bills, warm spots on floors, damp or cracking concrete, and the sound of running water.

Plumbers use non-invasive methods such as electronic acoustic sensors, ground microphones, infrared thermal imaging, tracer gas or dye testing, pressure testing, and concrete scanning to pinpoint leaks before breaking concrete.

Shut off the main water supply if possible, minimize water use, avoid digging or breaking concrete yourself, and contact a licensed plumber experienced with slab leaks to perform diagnostic testing and emergency mitigation.

Repair options include rerouting pipes around the slab, pipe lining or epoxy coating, targeted excavation and spot repair, partial or full repiping, and in some cases foundation stabilization. The best method depends on leak location, pipe material, access, and cost.

Simple rerouting or spot repairs can often be completed in a few hours, while excavation, repiping, or repairs requiring permits and concrete replacement may take several days. Inspection and drying time for affected areas can extend the timeline.

Costs vary widely based on access, repair method, pipe material, and the extent of damage. Expect anything from a few hundred dollars for a minor repair to several thousand for excavation and repiping. A qualified plumber can provide an on-site estimate after diagnosis.

Emergency response is available through local licensed plumbing partners for suspected slab leaks to help minimize water damage. Response times and after-hours availability vary by location.

Coverage varies by policy. Many policies exclude damage from gradual wear and tear but may cover sudden accidental damage or the resulting water damage. Review your policy and contact your insurer, and keep records and photos to support any claim.
