Finding a slab leak
Slab leak repair starts with leak detection. Pressure testing confirms which line is leaking, then acoustic and thermal equipment pinpoint where, so the plumber opens the floor in one spot rather than several. See our leak detection page for how that testing works.
Repair options
There are three common ways to fix a slab leak, and the right one depends on the pipe, the leak location and the condition of the rest of the system:
- Direct spot repair: open the slab over the leak, repair the pipe and patch the concrete.
- Reroute: abandon the leaking line under the slab and run a new line through walls or the attic.
- Repipe: when the pipe is failing in several places, replace the supply system rather than chasing one leak after another.
Why slab leaks happen
Copper under slabs can wear thin from water chemistry, abrasion against concrete or gravel, and expansion and contraction of hot-water lines. In homes from the 1970s and 1980s, a second slab leak is more likely once a first one appears, which is why plumbers often discuss rerouting or repiping instead of repeated spot repairs.

Frequently asked questions
Is a slab leak an emergency?
A slab leak can damage flooring and the foundation over time and waste a lot of water. If water is surfacing or the leak is large, shut off the main valve and call right away.
Is it better to repair or reroute a slab leak?
A spot repair can be fine for an isolated leak. If the pipe is old or this is not the first leak, a reroute often avoids future floor openings. The plumber can price both.
Does insurance cover slab leaks?
Many policies cover the cost of accessing the leak and resulting water damage but not the pipe repair itself. Review your policy and keep the plumber’s documentation.
