A leak below a concrete floor is slow and easy to miss. The first clue is often a damp patch on carpet, a lifting plank or a baseboard that stays wet, not a puddle. Moisture can rise through a floor for a long time before anything shows, so a damp patch deserves a meter reading before it deserves a guess.
What the first visit looks for
- A moisture meter walks the floor to find the wettest spot.
- Flooring is lifted at the edge to see the surface underneath.
- Baseboards and the base of the drywall are checked.
- A plumber confirms whether the leak is in a supply pipe.
The leak is repaired by a plumber. Drying follows only after the source is closed.
Drying a concrete floor
Concrete holds water and releases it slowly. Dehumidifiers and air movers are placed to pull moisture out of the slab surface and the air above it, and readings are repeated until the floor stops giving up water. Finished flooring on top cannot be put back until those readings settle.
Neighboring spaces
When water travels to nearby rooms, water extraction clears the surface and structural drying covers walls and subfloor.
