Plumbing in Berryessa, San Jose

In a slab-built house, the water lines that feed kitchens and bathrooms often run beneath the concrete. When one of them leaks, the water has nowhere to go but into the slab and the soil under it. The signs are indirect: a hissing sound, a warm spot on the floor, a water bill that jumps, or a meter that turns with everything off.

Finding the leak precisely is most of the job. We use acoustic and thermal tools to locate it before anything is opened, then explain whether a spot repair through the floor or a reroute through the attic makes more sense.

A single leak on otherwise sound pipe is usually repaired where it is. When a slab line has leaked more than once, or the pipe is thin throughout, rerouting the supply through the attic and walls retires the old lines entirely.

Berryessa's sewer laterals are often under driveways and mature landscaping. When one needs replacing, trenchless methods can avoid tearing up concrete and planting.
