How Slab Leak Detection in El Cerrito, CA Is Done
Booking slab leak detection in El Cerrito, CA gets you a full test sequence, not a quick listen and a shrug. These are the steps.
- 01
Meter and leak-dial check

Branch isolation
Lines are separated and tested one at a time, so the search is limited to the pipe that is actually losing water.

Thermal imaging
- 07
Marked location and options
The leak point is marked on the floor, and the realistic ways to fix it are explained before anyone quotes a repair.
