Houses in this part of the metro shipped with carpet and vinyl, so the wood underfoot now is nearly always a later remodel laid over the original slab. There are three ways that gets done and they behave nothing alike once water gets under them. Glued straight to the concrete, the adhesive line is what lets go, and the boards release in patches. Floated over a foam pad, the water spreads under the entire field and the pad holds it against the slab. Nailed to a plywood subfloor built up over the concrete, there is now a layer of wet plywood under your floor that no fan in the room will ever reach.
So the first thing we do on a hardwood floor water damage call is find out what we are standing on. A floor register, a length of shoe molding, or a threshold at a doorway shows us the plank edge and the underside, which tells us solid or engineered and what it was laid over. Everything after that follows from the answer. Solid wood that has cupped can usually be dried and sanded flat. An engineered veneer that has started to lift off its core is finished, and no amount of equipment brings it back.
Drying wood that sits on concrete
A slab-laid floor wants to dry upward through its own finish, which is the slowest possible direction, so we force it. Drying mats seal to the surface and pull moisture up through the boards under vacuum while a dehumidifier holds the room dry, and on a glue-down we work the perimeter to get air moving under the field. It is deliberately slow. Push wood too hard and it crowns and checks, which turns a floor you could have saved into a floor you have to replace. Readings come daily, and we stop at the moisture content of the same floor in a room that never got wet.
- Construction identified at a register or threshold before any plan is made
- Vacuum drying mats pulling water up through the boards, not fans blowing across them
- Drying paced slowly on purpose so the boards do not crown or check
- A straight answer on what will not come back, before the equipment bill grows

The honest version of this service is that speed decides most of it. A floor we get mats onto the same day often flattens back out. The same floor after a long weekend is usually a replacement, and we will say so instead of running equipment on it for a week. Call (512) 271-5099 as soon as you find it, even if you have already mopped up.
