What every slab leak water damage job includes
Extraction comes first
Truck-mounted and portable extractors pull free water before any fan goes down, since lifting liquid water out is far faster than evaporating it.
Dried to IICRC S500
Air movers and LGR dehumidifiers are sized to the class of loss, and the equipment stays until readings sit within 2 to 4 points of a dry reference.
A claim file built on site
Moisture maps, daily psychrometric logs and timestamped photos taken before any demolition give the adjuster a clear record of the loss.
Valley houses, valley habits
Slab floors with copper underneath, attic air handlers and large floor plans decide where water hides, so the walkthrough checks each one.

- Call a plumber. Leak detection finds the pipe so the repair can be planned.
- Mark warm spots. Note where the floor feels warm or the carpet stays damp.

What the claim file holds
Ranges are typical, not a quote: the water category, square footage, material class and how fast drying started move the number most. Sudden and accidental water from a pipe, appliance or tank is often covered by a homeowner policy, while surface flooding usually needs a separate flood policy, so check your own policy.
The mitigation team builds the file an adjuster reads: a moisture map, daily psychrometric logs, timestamped photos taken before demolition, the category and class, and a line-item scope. For a closer range, run the water damage cost calculator.
How slab leak water damage is handled, step by step
Map the slab
Thermal imaging and meters trace the wet area.
Lift flooring
Only materials that read wet come up.
Extract and vent
Water pulled and wall bottoms opened.
Dry the slab
LGR drying until readings reach dry.
Most homes in Walnut were built between 1970 and 1999, and many sit on a concrete slab with copper supply lines underneath. After decades, a pinhole can open under the floor, most often on the hot side, and water spreads through the slab before anything shows on the surface.
Signs the leak is under the slab
A warm patch of floor, a water meter that keeps moving with everything off, a bill that jumps or carpet that stays damp with no visible source all point under the concrete. The slab leak warning check scores those signs. A plumber finds and repairs the pipe; the restoration team handles the water it left behind.
Lifting only what is wet
Thermal imaging and pin and pinless meters map the wet area first, so flooring comes up only where readings call for it. Carpet and pad lift back easily. Glued wood and laminate over a wet slab usually come out, while tile can often stay if the grout lines release moisture.
Drying concrete takes patience
Concrete is dense and gives up water slowly. LGR dehumidifiers and air movers run across the open slab, and drywall and baseboards along the leak path are vented. Readings are logged every day until the slab and wall bottoms sit within 2 to 4 points of a dry reference, as covered on the structural drying page.

Meter moving with every tap off? Shut off the main and call before the water spreads under more flooring.
(888) 563-9619 Ask how slabs get driedHow do I know a slab leak is causing the water damage?
A warm floor spot, a moving meter with every fixture off, a jump in the bill or carpet that stays damp with no visible source all point under the slab. Leak detection by a plumber confirms it.
Who repairs the pipe in a slab leak?
A plumber repairs or reroutes the pipe. The restoration team handles the water damage: lifting wet flooring, extraction, drying the slab and walls and documenting the loss.
Does flooring always come out after a slab leak?
No. Moisture mapping decides. Carpet often lifts back and dries, tile may stay, and glued wood or laminate over a wet slab usually has to come up.
How long does slab leak water damage take to dry?
Concrete dries slowly, so five to ten days is common, longer when water sat for weeks. Equipment stays until readings sit within 2 to 4 points of a dry reference.
Does insurance cover slab leak water damage?
Many policies cover the resulting water damage and access to the pipe but not the pipe itself. Check your own policy; the claim file holds the moisture map, daily logs and photos.
