My dad and I just installed a bamboo hardwood click floating floor. We have one piece to go and realized that there is a 5' by 5' foot area (the total room is only 105 sq ft) that moves up and down when you walk on it.If you press on one board you can see 2 or 3 boards attached to it move.
It's a newer house and we thought the floor was level all around. I'm not sure if the problem is the floor or if it's possible that a couple of the click floor boards were somewhat warped. Any advice on the easiest way to fix this problem?
