We bought this house last year. They had recently (just before we bought it) installed hard wood flooring from the entry through the kitchen. Earlier this week the floor got wet for a few hours. Now, it appears the long side edges of each board is starting to lift up. I can feel the transition from one board to another in this area, where it isn’t apparent in other areas of the flooring (that didn’t get wet). A few boards are also showing signs or problems where two boards butt up to each other. This flooring was installed using staples through the subfloor, which is evident in the basement below.

Will the wood dry out and be fine? Is there anything I can do? I really don’t want to rip out this section and replace it, as I’d have to start in the area of the entry which isn’t showing signs of problems….

Staples through the subfloor? Ok… First thought past a weird installation is – is it that laminate flooring? That stuff can’t handle getting wet and will not return to normal. NOW – if it is the laminate ‘barfboard’ and it is in writing the kitchen was HARDWOOD floor – you can force the real estate agent to replace the floor. It is called specific performance and I would get an estimate from a professional for the whole job and if offered half of that grab it and run instead of paying a lawyer.

Not much you can do once the cheap fake wood flooring gets moister in it your done (good that you can see the staples pound them out from the bottom

This is not fake wood flooring, it’s real hardwood. I know the difference and I can spot it. I have a few extra pieces left in the garage and I’ve examined it. Although I appreciate the suggestion with the real estate agent, this doesn’t apply, since it was billed as, and is, real hardwood flooring.

Real wood – put some concrete blocks on it while it dries – or something heavy to hold it in place. Possibly, add a little wood glue squirted under with a syringe? If needed – pre drill and use small head trim screws to flatten it out and you can putty in with a matching or darker putty (think wood knot)

Don’t try to patch it with cinder blocks and glue, you won’t be happy with it. as I said in my post from early this morning— have no idea where my posts go for about ten hours but anyway Get a dehumidifier, and run it for a few days in the room with the problem, you may get lucky. One of 3 things will happen, 1.you get lucky and the boards go back where they belong and you can reseal the floor with “poly” to try to seal the edges between the boards, 2. the boards go back down but the edges still feel raised and you have to sand and refinish the floor, or 3. the boards cup so badly that you need to replace a number of them, then refinish the floor. Most folks that lay a pre-finished hardwood floor, do not put any kind of finish over the floor once it is laid, I mean it looks good so they don’t. We always put 2 coats of a good “poly” over any pre-finished floor that we lay, it gets down and fills the cracks between the boards and makes it less likely that a spill will get into the wood.

Give it time to see if it settles down. If you refinish it, and it settles back down, it will look like crap again. i have a similar situation with my wood floor, except water came in via a window while I was out of town. I am running a dehumidifier all the time, and it does seem to be getting better, but I am going to wait until next spring to see what it looks like then before doing anything about it.

If I read you right, the flooring is not coming up, but has swelled at the edges and so the floor is “wavy” with high spots at the edge of the boards and low in the middle part of each board. Probably won’t go completely away when it dries, but you don’t have to replace, just sand and refinish.

This is what happens when hard wood floors get wet…they cup like you are experiencing. If you are very lucky, the edges will smooth a bit but I doubt they will every return to the native level. When this happened to me, I had to sand the cupped edges level and refinish.

Thanks so much for all the replies. I will wait for it to try out and attempt to sand and refinish. I’ll also put a couple of coats of poly on the entire floor when I’m done. Since this hardwood carries into the kitchen, I’m sure to have the same problem in the future if I don’t do something about it now. Suggestions on which brand of poly to use?
