Water from a slab leak comes up through concrete instead of down from a ceiling, which is why it goes unnoticed. Floors differ from house to house here, so the crew first confirms what is under the finish: a lower-level slab, a garage or addition slab, or a heated floor with tubing in it.
Clues that point under the floor
- Carpet or flooring that feels damp or warm in one area
- A meter dial that moves while nothing is running
- A boiler for a heated floor that keeps dropping pressure
- Lifting tile or a musty odor along one wall
The city Utility Division reads water meters. A bill that climbs while use stays the same is reason enough to watch the meter with every fixture shut.
How the slab is dried
Concrete is a Class 4 material: it holds water deep and releases it slowly. Once a plumber has fixed or rerouted the pipe, readings set the wet boundary, the flooring and pad over it are pulled, and desiccant or LGR dehumidifiers work with air movers on the concrete. Drywall and framing at the base of nearby walls get checked too, because water climbs into them.

Slab and Under-Floor Leak Water Damage questions in Woodbury, MN
How many days does a slab need to dry after a leak?
Four to ten days is typical. Concrete lets go of water slowly, so a leak that ran for weeks needs longer than one found early.
Must all the flooring come up for a slab leak?
No. The carpet and pad over the wet zone usually come up, but tile or vinyl can stay when readings show the slab drying through or around it.
Who locates a slab leak under the floor?
A plumber pinpoints and fixes the pipe, often by acoustic or pressure testing. The restoration team then maps the moisture, pulls what is wet and dries the concrete.
Does insurance pay for slab leak water damage?
Sudden water damage is often included, while the pipe repair itself and slow leaks may be handled differently. Check your policy and keep the plumber's written findings.
Can a heated floor leak like a slab leak?
It can. Tubing in a heated concrete floor can fail, and a boiler that keeps losing pressure is the usual clue. A heating contractor fixes the loop, then drying begins.
How much does slab leak water damage cost here?
Typically $2,000 to $9,500 for removal and drying, depending on how long it leaked and the flooring removed.
