A slab leak is a break in a pressurized supply pipe that runs in or beneath a concrete floor. Water works its way up through cracks and joints, so the first sign is often damp flooring or a water bill that jumps. In Bonita's tract homes from the 1960s to 1980s, the leak can run quietly for a while.

How slab leak water damage is handled in Bonita
The tech who does the walkthrough maps moisture before any equipment goes down, so the drying plan matches what is actually wet. Equipment stays until the readings say dry, not until it looks dry.
- 01
Trace the water
Meters show where it spread.
- 02
Open the flooring
Wet sections are lifted and trim comes off.
- 03
Dry the slab
Dehumidifiers and air movers pull moisture from concrete.
- 04
Confirm dry
Final readings match the dry reference.
Signs the leak is under the floor
- Warm or damp patches on tile, wood or carpet
- A hissing sound near a floor when fixtures are off
- A water bill that rises with no change in use
- Baseboards, cabinet toe kicks or wall bottoms that swell
Any of these signs justifies a moisture check before flooring is removed. Readings across the floor show how far the water has spread and whether a plumber's leak detection is needed to find the break.
Opening and drying the wet area
Flooring over the leak is lifted, baseboards come off and the lower wall is checked. The concrete itself holds moisture, so dehumidifiers run for several days, and desiccant units are used where deeper drying is needed. Tile can often stay if the material beneath it dries out, but wood and laminate that cupped usually come out.
Kitchen cabinets and wall bottoms
When the leak sits near a kitchen or bathroom, cabinet toe kicks and the bottom of the walls are opened so air can reach the cavity. Drying continues until the readings on cabinets and drywall return to the dry reference taken in an unaffected room of the same home.
Coordinating with the plumber and the claim
The plumber repairs or reroutes the broken pipe, much like a burst or pinhole pipe leak, and the drying team schedules its work around that repair. Photos of the opened floor, moisture logs and equipment records go to the adjuster, and a structural drying plan covers any walls that need more time.

Slab Leak Water Damage questions in Bonita, CA
Still dealing with it?
Damp floors or a rising water bill in Bonita?
(888) 450-9281Book a floor moisture checkHow can a slab leak be confirmed?
A plumber's electronic leak detection pinpoints the break, while moisture meters and thermal imaging from the restoration team show where the water has spread.
Does the whole floor have to come up?
Usually not. Only the wet sections are lifted, based on readings, and tile over a dry bed can often stay while wood and laminate that cupped are removed.
How long does concrete take to dry?
Concrete releases moisture slowly, so drying often runs several days and sometimes longer, with readings taken at each visit before equipment is removed.
Will insurance cover a slab leak?
Coverage depends on the policy. Many pay for the resulting water damage but not always for repairing the pipe itself, so the adjuster needs photos, logs and the plumber's report.
Can mold start under flooring after a slab leak?
It can if flooring stays damp past 24 to 48 hours, which is why wet sections are opened and dried rather than covered over.
Should the water be shut off at the main valve?
If the leak is active and the source is not obvious, closing the main valve stops the flow until the plumber can trace and repair the broken pipe.
