I had some water damage a couple years back and my floor was completely replaced after drying the sub floor. Both the people who dried it and the new floor guy said it was dry enough to put new floor on.
But since then I heard a popping sound once in a while which started at my feet and spanned the replaced area. It happened for a month every time the temperature was changing (spring / fall). I'm in New England.
Just now I heard the popping and noticed that the floor had popped up like a mountain range. It's getting colder now and I'd imagine the dry air would make the wood shrink. It's red oak. The closet which had been popping is popping less now that the floor erupted.
What is the cause? Should I fix this myself? If my entire walk-in closet is popping, should it all be replaced as well?
