Hidden Beneath the Concrete
Slab Leaks Are Common in San Diego Homes
A slab leak is a water leak in a pipe beneath your home's concrete foundation. Much of San Diego was built after World War II with slab-on-grade construction, so thousands of homes have copper water lines buried under the concrete.
Hot-water lines are the usual culprit: heated copper expands and contracts until it rubs through against abrasive concrete. Hard water corrodes it from inside, and shifting clay soil stresses it from outside. We find leaks non-invasively with electronic and acoustic detection, thermal imaging, and pressure isolation.

Slab Leak Questions, Answered
Still have a question? Call us at (619) 637-5215.
How do you detect a slab leak without breaking the floor?
We use non-invasive electronic and acoustic detection, thermal imaging, and pressure isolation to pinpoint the pipe before opening the floor.
How much does slab leak repair cost in San Diego?
In 2026, detection runs $300 to $600, spot repair about $1,000 to $4,000, and rerouting $1,500 to $4,500. We give a written price first.
Is rerouting better than jackhammering the slab?
Often, yes. Spot repair breaks and patches concrete, disturbing flooring. Rerouting runs a new line through the attic or walls and keeps the slab intact.
Will my home insurance cover a slab leak?
Insurance usually covers the resulting water damage but not the pipe repair, which counts as maintenance. Policies vary, so check yours.
How urgent is a slab leak?
Treat it as urgent. An unrepaired slab leak can cause foundation movement, mold, warped flooring, and costly structural repairs.
