02Why slabs leak

Slab leaks in Winnetka, CA

Aging copper

Copper under older slabs thins from the inside and from contact with soil and concrete, until a pinhole opens under the floor.

Hard water and pressure

Los Angeles tap water is hard, and street pressure works on every joint. Hot water pipes fail first, which is why warm floor spots are a classic sign.

Ground movement

Clay soils swell when wet and shrink when dry, and earthquake shaking moves the slab too. Both stress the pipe where it passes through concrete.

Already wet? See slab leak water damage, water extraction and hardwood floor drying.

How do I check for a slab leak with the water meter?

Turn off every tap, appliance and irrigation, then watch the meter's leak indicator for several minutes. If it still moves, water is going somewhere.

Why is the floor warm in one spot?

A leak on the hot water pipe under the slab heats the concrete above it. Warm spots near the kitchen or a bathroom are a common sign.

Who finds and fixes the leaking pipe?

A plumber runs electronic leak detection and repairs or reroutes the pipe. The restoration team handles the water: lifting wet flooring, extraction and drying the slab and walls.

Does homeowners insurance cover a slab leak?

Many policies cover the resulting water damage and access to the pipe but not the pipe itself. Coverage depends on your policy, so check with your own insurer.

Can a slab leak wait a few days?

A leak under the slab keeps feeding water into the concrete, flooring and wall bottoms. Shut off the main if the meter keeps moving and get it looked at.

24/7 emergency dispatch
