How we find and fix it

Slab Leak Detection, explained

We isolate hot and cold, pressure test each side, then use acoustic and thermal equipment to pinpoint the leak.

Then we lay out the options: a spot repair through the slab, a reroute through the attic or walls, or a repipe, with cost for each.

Why pipes fail here

Slab Leak Detection in San Antonio: local factors

Most San Antonio homes are built on slabs over expansive clay. The swell and shrink of that soil through wet and dry cycles puts stress on lines under the foundation. Catching a slab leak early protects the foundation itself.

We work from 8666 Huebner Rd and cover the Medical Center, Leon Valley, Castle Hills, Shavano Park, Helotes, Alamo Ranch, Stone Oak, Alamo Heights, and the surrounding communities, around the clock.

Questions

Slab Leak Detection FAQ

Is it better to reroute or break the slab?

It depends on where the leak is and how old the pipes are. We quote both.

Can a slab leak damage my foundation?

Yes. Water under a slab can soften the soil and contribute to movement.

A leak costs more every hour it runs.

Shut the supply off if you can reach the valve, then call. We answer 24 hours a day, 7 days a week.
