Electronic Slab Leak Detection

A slab leak is a leak in the copper water lines buried beneath your home's foundation. Finding it without digging requires skill. We use acoustic listening discs and electronic "sniffers" to hear the frequency of escaping water through the concrete. We pinpoint the exact location, marked with an X, so repairs can be focused and minimally invasive.

Repair Options: Spot Repair vs. Reroute

Once a slab leak is found, we offer solutions tailored to your home:

Spot Repair: We open a small hole in the floor to fix the specific section of pipe.
Pipe Reroute: Often the better long-term option, we abandon the old underground line and run a brand new PEX line through the attic or walls, eliminating the risk of future leaks in that run.

Frequently Asked Questions

Is a slab leak an emergency? Yes. Even if you don't see water, the leak is eroding the soil under your foundation, which can lead to cracking walls and structural settling.
Will my insurance cover leak detection? Most policies cover the "access" to the leak (tearing out the floor) and the drying, but not the pipe repair itself. We can help document the find for your adjuster.
How do you find leaks inside walls? We use thermal imaging cameras to detect the temperature difference created by evaporating moisture, alongside moisture meters to map the wet area.
What causes slab leaks in San Anselmo, CA? It is often a reaction between the copper pipe and the pH of the soil or concrete, or simple friction from the pipe expanding and contracting against the concrete.
Can you detect a leak in the main line outside? Yes. We can listen for leaks in the yard service line and repair or replace it without digging up the entire trench.
