Solid wood is a sponge with a finish on top. Water gets in at the seams and the underside, the boards swell against each other, and within days the edges lift into cups or the whole floor buckles upward.
Dried in place or taken up
When the water was clean and the boards have only begun to cup, floor drying mats and panels pull moisture up through the wood while dehumidifiers remove it from the air. When boards have buckled, or when contaminated water soaked them, the flooring is removed in sections so the subfloor underneath can dry.
Moisture trapped under the finish is the hidden problem. A floor can look flat and still be wet underneath, which is why meters, not eyes, make the call.
What the readings decide
Moisture meters check the boards, the subfloor and the edges at every visit:
- Board moisture compared with a dry reference floor
- Subfloor readings below the wood
- Baseboards and cabinet edges
- Cupping measured so changes show up
Refinishing waits for dry readings
Those numbers are written down so the flooring contractor and the insurer can see the same story the crew sees. Sanding and refinishing too early traps moisture and can make the floor cup again. A floor dried to a verified dry goal can often be sanded and refinished, and the readings give the flooring contractor the proof.
If the water came from a pipe in the wall, burst pipe water damage covers the wall side, and standing water on the boards starts with water extraction.
