Buckling

This is the most extreme reaction to moisture in a hardwood floor. This occurs when the wood flooring actually pulls up from the subfloor, lifting several inches in one or more places. Fortunately, this is not a common occurrence. Buckling happens most often after a floor has been flooded for an extended period of time. If caught early, spot repair and replacement may be possible. Once the standing water is removed, several boards can be taken up from the floor so that the air can circulate across and below the floor. Once the floor has dried to a more stable moisture level, repairs can usually be made.
