Cupping refers to the edges of a board rising above its center. Humidity, spilled water or leaks rising up from the basement cause swelling, resulting in warped edges. You can reverse cupping by reducing humidity, stopping leaks and letting the wood dry out on its own or using fans to help. In more severe cases, you may have to refinish the floor. Our Tulsa Floor Care experts want to catch this problem before it gets worse.
