Slab Leak Detection & Repair in Norwalk & La Mirada
A slab leak occurs when a water line running beneath your concrete foundation develops a crack or hole. Left unaddressed, the escaping water erodes soil under the slab, causes foundation settlement, promotes mold growth, and can result in tens of thousands of dollars in structural damage.
Many homes in Norwalk and La Mirada were built in the 1950s through 1970s with copper water lines embedded in or beneath the concrete slab. After 50 to 70 years, those pipes are reaching the end of their lifespan and slab leaks are increasingly common in our service area. Our plumbers have repaired hundreds of slab leaks across the region and can walk you through every option from spot repair to full reroute.
Our Slab Leak Repair Process
Leak Confirmation
Using electronic leak detection equipment, we confirm the leak is under the slab and pinpoint its exact location. We mark the spot on the floor so you can see exactly where the problem is before any work begins.
Repair Strategy
We present your options: spot repair (opening the slab at the leak point), pipe reroute (abandoning the under-slab line and running new pipe through the walls or attic), or full repipe. Each option has different cost, longevity, and disruption tradeoffs.
Repair Execution
For spot repairs, we carefully cut a small section of slab, repair or replace the damaged pipe section, pressure test, and patch the concrete. For reroutes, we run new PEX or copper lines through accessible areas.
Pressure Test & Closeout
Every slab leak repair is pressure tested before we close up. We verify the system holds pressure for a sustained period, then restore the floor and clean up completely.
