I'm told I have a cupping problem with the new wood floor I had installed a year ago.
It's 21/4 wide. with 15# felt.
Wood floor cupping is not necessarily an outcome from moisture in a crawl space but could be a combination of items.
You should investigate these possible causes:
- Relative humidity in the home;
- Grade and species of wood floor;
- Moisture content of wood floor;
- Improper installation and fastening;
- Possible water infiltration.
