Common Slab Leak Repair Scenarios
Under-Slab Water Leak
Water lines running beneath your concrete slab can corrode and leak. Warm spots on floors, rising water bills, or the sound of running water when everything is off are telltale signs.
Slab Leak Detection
Electronic leak detection equipment pinpoints the exact location without breaking concrete. Essential before any repair to minimize demolition.
Spot Repair (Jackhammer)
Breaking through the slab at the leak location, repairing the pipe, and patching the concrete. Best for single, accessible leaks.
Reroute (Overhead Repipe)
Abandoning the leaking under-slab pipe and running a new line through the walls or attic. Best when multiple slab leaks indicate systemic pipe failure.
Frequently Asked Questions
How much does slab leak repair cost in Los Angeles, CA?
Slab leak repair in Los Angeles typically costs $2,000-$6,000. Leak detection alone runs $200-$500. Spot repair through the slab costs $1,500-$3,500. Overhead reroute (abandoning the under-slab pipe) costs $3,000-$6,000+ but prevents future slab leaks.
How do I know if I have a slab leak?
Watch for: unexplained increases in your water bill, warm spots on your floor, the sound of running water when everything is off, cracks in your foundation, mold or mildew near the floor, and low water pressure. Slab leaks in Los Angeles homes are often caused by shifting soil or pipe corrosion.
Should I repair a slab leak or reroute?
A single isolated leak in a newer pipe is a good candidate for spot repair. If your Los Angeles home has older pipes (galvanized, copper with a history of pinhole leaks), a reroute prevents future slab breaks and avoids repeated concrete demolition.
Does insurance cover slab leak repair in CA?
Most homeowners insurance in CA covers water damage from a slab leak but NOT the cost of accessing and repairing the pipe itself. Some policies cover both — check your endorsements. Document all damage with photos before repair begins.
