I was wondering if anybody could help me out
My flooring is has a small hump in it and when you walk on it it flatens out. The sub floor looks like it is well supported don see any sagging. Any thoughts
This assumes that is once was OK, and all the boards are correctly snapped together. When the floor was installed there was suppoed to be a space of about 1/4 all around to allow for expansion. If that space is not there, the floor will bulge if it cannot expand.
