Not every leak announces itself. When a supply pipe fails in or beneath a slab, water can spread under flooring and up into the bottom of walls, and the first clues are often subtle: a damp spot, lifting laminate, a musty smell or a household water use number that keeps climbing.
Clues that point to a slab leak
- A warm or damp patch on the floor
- Laminate, tile or wood lifting without a spill
- Baseboards swelling or drywall staining low on walls
- A musty smell that returns after cleaning
- Water use that climbs when nothing in the home has changed
Floors feel damp or the water bill keeps climbing. Describe what you see and the moisture search can begin from there.

The City offers EyeOnWater, which uses automated meter reading so customers can track household water use. A steady climb with no visible cause is worth a plumber's attention, and a plumber, not the restoration team, finds and repairs the pipe. Drying starts once the pipe is stopped.
Drying a wet slab and what sits on it
Concrete holds moisture for a long time, so flooring over a wet slab is lifted and the slab is dried with dehumidifiers and air movers rather than left to evaporate. Structural drying explains the equipment, and readings confirm when the slab is ready for new flooring.
Water from a leak under the slab can also reach walls and cabinets, and any standing water is handled under water extraction before the drying equipment is set.
Slab Leak Water Damage in short
Floors and walls wet by a slab leak are mapped with moisture meters, opened where needed and dried, so the damage is found and handled before it spreads further.
