The full picture

Slab Leak Water Damage: what to know

In a home built on a concrete slab, the water pipe travels under or through the concrete. A pinhole there can push water into the flooring and toward the baseboards for weeks with no stain to give it away, so the job begins with a meter and a moisture map rather than demolition.

Clues that point to the slab

  • A meter dial that turns while every tap is closed
  • A floor patch that feels warm where a hot-water pipe is leaking
  • Carpet that stays damp, vinyl that lifts or tile that cracks for no clear reason
  • A sudden jump in the water bill

A plumber's leak detection then pins down the exact spot.

Getting concrete back to dry

Concrete holds water deep and lets it go slowly, which puts it in the hardest drying class. After the break is repaired, flooring over the wet zone is lifted and the baseboards are pulled. Desiccant or LGR units and air movers aimed low then work on the slab and the base of the walls, and surface readings say when it is ready for new flooring. More on the equipment is on the structural drying page.

Who handles which part

The plumber owns the pipe: locating the break, then repairing it or running a new route. The restoration crew owns the water: extraction, removing wet flooring, drying and keeping the moisture log an adjuster asks to see. If water is pooling on the surface first, water extraction comes before drying. A home meter test and a call to the insurer settle most early questions.

Before the crew arrives

Shut the water off at the fixture valve or the main, keep clear of wet outlets and cords, and take photos before anything is moved or thrown out.

(888) 578-6508 (888) 578-6508Have the slab moisture mapped
How is a slab leak found?

The first hint is a meter that moves while nothing is running. A plumber narrows it down with electronic leak detection, and a moisture map shows how far the water spread.

Why is one part of the floor warm?

Hot water escaping from a pipe under the slab heats the concrete over it. A warm spot close to a kitchen or bath often marks the leak.

Does every floor in the room have to come up?

No. Only flooring sitting on damp concrete, or flooring that has absorbed water, gets lifted. The readings outline the wet zone so the rest can stay put.

Why does concrete take so long to dry?

A slab is thick and tight, so water inside it moves out slowly. Desiccant or LGR dehumidification over several extra days is common compared with walls or carpet.

Does homeowners insurance pay for a slab leak?

Policies often pay for the water damage and for opening the floor to reach the pipe, but not the pipe repair. Confirm the terms with your insurer.

Is it safe to wait a few days?

Waiting lets the leak keep feeding water into the slab, flooring and lower walls. Close the main if the meter keeps moving.
