Slab leak repair
What this service covers
Slab-on-grade construction is everywhere in San Marcos and North County, which means copper supply lines running under concrete. When a line under the slab fails — from abrasion, soil chemistry or a pinhole after decades of hard water — you get warm flooring, a running meter, or moisture wicking up through the finish.
There are two honest paths. A spot repair opens the slab at the located point and replaces the failed section: least disruption when the rest of the system is sound. A reroute abandons the under-slab run and re-pipes overhead or through walls: more work, but the right call when the same line has leaked before or the piping is at end of life. We quote both and explain which we would choose in your house.

Common questions
Slab Leak Repair FAQs
Q. Is a spot repair or a reroute better?
A spot repair is less invasive and cheaper when the rest of the piping is in good condition. If the same line has already leaked once, a reroute usually costs less over the life of the home.
Q. Does homeowners insurance cover slab leaks?
Many policies cover resulting damage and access, though coverage of the pipe itself varies. We document the location, cause and work performed so you can file with clear evidence.
Q. How disruptive is opening the slab?
Less than most people expect when the leak is pinpointed. We contain dust, cut only the marked area and patch the concrete when the repair is verified.
Q. How fast can you respond?
We are available 24/7. If water is actively damaging your home, call and we will walk you through shutting off the main while we are on the way.
