How Slab Leak Detection in Lancaster, CA Is Done
Every visit for slab leak detection in Lancaster, CA covers the same checks, in the same order, so the result is something you can act on instead of a guess.

Call (774) 252-0684How much does slab leak detection in Lancaster, CA cost?

Can you have a slab leak and not know it?
Yes. Cold-water leaks give no warm spot, and small ones barely move the meter. A pressure-gauge test catches leaks too small to see any other way.
How long can a slab leak go undetected?
It can run for months or longer if the water soaks into the soil rather than surfacing. Often the only clue is a water bill that keeps climbing.
How do you find a cold water leak under a slab?
Because a cold leak does not warm the tile, a thermal camera will not see it. Each line is isolated and tested, then the run is followed with acoustic equipment.
