Slab Leak Detection & Repair in Lake Forest, CA

Slab leaks occur when water supply or drain lines running beneath your concrete foundation develop cracks, pinhole leaks, or joint failures. These leaks can run undetected for months, wasting water, promoting mold growth, and undermining your foundation. Modern electronic leak detection pinpoints the exact location of the leak so plumbers can access and repair it with minimal concrete removal, or reroute the line overhead if that is more cost-effective.
