Movement in the Flooring is a normal occurrence with seasonal changes. In summer, when the humidity is higher, the floor will expand. This can cause cupping and crowning. In the winter, when humidity is lower, the floor will contract. This normal expansion and contraction is not a defect. To maintain the best performance of your wood floors, use humidification to maintain humidity at 45% to 55%
