that's not a foundation issue.... it could be the quality of the strips of wood... but I think it's the humidity causing swelling and if the bundles of strips are not left in the home for a few days to adjust to the humidity in the home, they will cup after the installation.... each strip is tapped into place with a rubber mallet and when they swell that's the photo....

Yes. Usually a sign of moisture issues. Not typically a problem in Central Oregon unless there has been a plumbing leak

Definitely a moisture problem. Just moved out of a condomnium that had a flood. The floors are seriously cupped and will be replaced.

Sometimes flooring isn't cured. I wonder if that could have been an issue?

    Cupping usually gets blamed on moisture coming through either off-grade subfloor, or moisture coming through an unsealed slab. 

    This is the first Inspection letter I've seen where it is blamed on poor installation!

It could be a little bit of both but I would suspect the floor first before going nuts. Install is the #1 problem or thing that I would investigate first.

He's saying the floor is installed upside down. With pre-finished flooring how can that be?

It is the wood, not foundation. Humidity will do this as well as wet mopping frequently which some actually do

Two things typically cause that issue here, Fred:

1. The wood needs to sit inside, climate-controlled space to acclimate to the temperatures for, I believe, at least 4 days. Some builders are pushing their deadlines and skip this step. 

2. The majority of issues here are in older homes with moist crawl spaces or basements. When the moisture issues are resolved, in a few weeks, the cupping goes away.

Sounds like an installation issue; wood swells, installers need to allow for that.

I had a leak from the water line in the refrigerator, and caused the cupping.  It took 6 months, but the wood finally dried out (we are dry here in CO), and eventually went away.

Cupping happens here in Georgia either due to moisture in the slab or the slab was not prepped properly prior to installation of the flooring.

Yes, I see often...too often.


Looks like a moisture/water/humidity issue.  the question is the source.


Is it solid or engineered? (kind of looks like engineered)  How installed?  What's below it?  How was it installed?  Nailed or glued?  (doesn't look like floating)


It could be due to many things.  It could in fact be from foundation, if foundation wasn't sealed, or due to hydrostatic pressure - if ground is very saturated with water.


could be due to not acclimating long enough and/or not a proper temp and that humidity readings weren't done before installing.


Could be due to water leak somewhere.


could be due to humidity levels in room/home are too high


I have seen all of these issues and more.


I don't understand inspector's note.  that makes no sense to me.  But then again, what do I know, LOL.

Glued underneath. Need floating type....

Buckling -membrance bends and give way under pressure or strain.

You have to have the wood acclimate for at least a week or 2. Also the home has to be ventilated well. Bamboo/pergo is the best for Florida but Tile is the safest.

That I've not seen.  Of course we always let it sit for a week or so in the house to get used to the weather in the house and install it with a small gap under the baseboards to allow for expansion.

I agree with the inspector if it were our neck of the woods.  Poor installation causes this as flooring has to have room to move.  It has to acclimate as well for at least 24 hours.  

Could be from Moisture but not always.

Seen it before.

Bad/untimely installation can do it.  I've seen it.  When hardwoods are delievered they should be unwrapped and sit in the space for a time before installation.  When people skip that wait period and install immediately this can be the exact outcome.
