Leak Detection & Repair in San Jose, CA
Water always finds a way out — and by the time you can see it, it has usually been escaping for weeks. A climbing water bill, a warm spot on the floor, a musty smell in one room: these are the quiet signs of a hidden leak, and catching them early is the difference between a pipe repair and a remodel.
We locate leaks with pressure testing and acoustic detection before we ever open a wall, so the repair is surgical instead of exploratory. Slab leaks — common in San Jose’s slab-on-grade neighborhoods like Almaden and Blossom Valley — can often be rerouted overhead rather than jackhammered, and we will lay out both options with costs.
Not sure you have a leak? Try this: turn off every fixture and watch your water meter’s leak dial. If it moves, call us — the phone consultation is free.

Frequently asked questions
How do you find a leak without tearing up my house?
We isolate sections of the plumbing with pressure tests to confirm which line is leaking, then use acoustic listening equipment to pinpoint the spot. Only then do we open the smallest access needed for the repair.
What is a slab leak and why are they common here?
Many San Jose homes built from the 1950s–1980s have copper water lines running under the concrete slab. Decades of our mineral-heavy water plus slab movement wear pinholes in the soft copper. Repair options are a spot repair, a reroute above the slab, or repiping — we will recommend the one that makes sense for the pipe’s condition.
Will insurance cover a leak repair?
Policies usually cover the water damage a sudden leak causes, but not the pipe repair itself, and rarely damage from long-term slow leaks. We document everything we find with photos so you have what you need for a claim.
