Hi Rob, sorry the video didn't go deeper into fixing cupping, honestly the only other option if the suggestions we've made in this video don't fix the issue, is to refinish the floors and that would be a different video all together. Thank you for the comment and we're here to answer any additional questions you may have.
It sounds more difficult than it actually is. Very easy if you are a windows shut with A/C or heating on kind of family. If you're a windows open all the time type family it can get trickier. That said, this is what we've found to be solid flooring's safe zone. Also, 99% of cupping issues are either due to wet mopping or moisture coming from a concrete slab, humidity is actually a very small contributor. Thanks for watching and the comment!
Long story short, you have a moisture issue. Fix the moisture issue and then you have to wait and see if the planks will uncup on their own. If there is no change after a month or two, you'll either have to sand and refinish or replace the floor.
Just bought this new house with a cupping issue. I tried asking a sanding professional to come in and sand my cupping floor. But they said it's not possible since it may damage the floor further and will make everything loose. Is he correct?
@@barryliu3325 Flooring refinishers (unlike some installers) tend to know what they're talking about. Maybe the cupping is too far gone or maybe the floors have been refinished several times already? Either way cupping is usually a result of improper cleaning (wet mopping) or there is an underlying moisture issue. Before you replace the flooring you'll want to have your subfloor inspected and tested for moisture. The quick fix (which is often cheaper than refinishing) is to put down an underlayment and lay vinyl plank right over the top, assuming the cupping isn't too severe.
6 mil plastic in crawl spaces up the wall overlap and tape preferably Rock under it open and close vents depending on season check your downspouts caulk around sliding doors windows but most important of all when installing new make sure test hardwood and floor for proper moisture content and use Mulligan moisture mat if you use wide boards glue assist boards
Hi Bill, if you have successfully identified your source of moisture and have remedied it and after 3 months your floors haven't returned to a normal state, your last option is to have the floors sanded flat and refinished by a professional floor refinisher.
@@CaliFloors I have cupping at one plank intersection from a spill. Is there anything I can do besides waiting to safely speed up the drying process? Thank you!
We have a slightly cupped floor. We leave the windows open in the summer. If we sand and refinish the floor will it crown come winter when the humidity goes away?
If you don't identify what caused the cupping in the first place there will likely be more issues in store for you. Are you wet mopping? What is the subfloor?
Hi Roger, if the suggestions in this video don't resolve your issue then the only thing left to do is sand and refinish. Refinishing should only be performed if you are certain the source of moisture issue has been addressed, otherwise it will cup again.
Video should have been titled why wood gets wet and how to do absolutely nothing
There is almost NO help on techniques used to resolve cupping in wood planks. Please delete "Fixing" in the title of this video.

Wood acetilation, or simply heat treated wood?
Yes there are ways to fix cupping, you're obviously an amateur.
Keeping humidity within a 20% range? What the heck? Unless you live in AZ, no one has that range very often

We've never wet mopped our wood floors, yet it happens every summer here in Florida.

Joe knows!
Nothing about fixing, only preventing...

This is a big problem with wooden floors
Would like more information on how to treat DIY. Calling a professional is a cop out of a fix.
Have you identified the source of the moisture? Are you wet mopping the floors?
