A pinhole leak under a concrete slab can wick water upward for days before anyone notices soft flooring or a stain. Local crews extract the water, dehumidify, and coordinate the slab-leak repair.
Thermal imaging and acoustic listening equipment locate the leaking line under the slab without breaking concrete prematurely.
Submersible pumps and specialized equipment remove standing water from under the slab, basements, crawlspaces, and affected flooring.
Dehumidifiers run for 10 to 21 days to pull residual moisture out of concrete, soil, subflooring, and structural materials beneath the slab.
A plumber repairs or replaces the damaged supply line and tests the system, and flooring or concrete work follows once the space is fully dry.
While help is on the way, these first steps, done only where it is safe, limit the damage and protect the insurance claim.
Shut the supply off at the source, or close the home's main valve if the source is not obvious. Stopping the flow limits the damage more than anything else.
Switch off electricity to the affected area, but only if the breaker can be reached without standing in or touching the water.
Get a crew dispatched right away. The sooner extraction and drying begin, the more flooring, drywall, and belongings can be saved.
Take photos and a short video of the water and the affected rooms before anything is moved, so the insurance claim starts strong.
Slab leak water damage restoration typically runs $2,000 to $7,000, depending on the size of the leak, how long it ran before detection, how many areas of flooring were affected, and whether the supply line can be repaired or has to be replaced outright. The plumbing repair itself is billed separately from the water damage cleanup. Insurance may cover water damage from a sudden pipe failure but typically does not cover the cost of the line repair itself.

Signs include soft spots in carpet or flooring, water stains on floors or walls, a musty smell, tile cracking in a line, a water bill that jumps for no clear reason, or water pooling on a basement floor with no rain or plumbing backup involved.
Sometimes. A plumber can often reroute the supply line above the slab instead of cutting into the concrete, or repair the line by boring horizontally under it. The right approach depends on the specific layout and is something a plumber assesses on site.
It depends on how long the leak ran and how much water sat under the slab. Flooring caught and dried early can sometimes be saved. Water sitting under the slab for more than about 72 hours usually means replacement is the safer call.
Initial extraction usually takes one to two days. Fully drying concrete, soil, and subfloor can take 14 to 21 days depending on slab size and how saturated the area is. Plumbing repair happens alongside the drying, not after it.
Most homeowners policies cover water damage from a sudden, accidental pipe failure under a slab, though they typically don't cover the plumbing repair itself. Some policies exclude coverage when the slab isn't part of the home's main structure, such as a garage slab, so it's worth reviewing the specific policy.
