Damaged wood floors can occur due to several factors, such as moisture, scratches, dents, or wear and tear. Moisture can cause the wood to warp or buckle, while scratches and dents can result from heavy furniture or sharp objects. Wear and tear over time can also lead to the dulling of the wood’s finish and the appearance of scratches and dents. Repairing damaged wood floors may involve sanding, refinishing, or replacing damaged planks, with the specific approach depending on the severity and type of damage.
