How to patch hardwood floors

Part of the charm of hardwood floors is their imperfections. Slight variations in grain and color, as well as the minor spots and specs in the wood help provide an aged-to-perfection look for your floors. However, you may encounter a cracked plank or damage to a section of your floor that doesn't look quite so attractive.
Never fear. Single planks or small sections of floor can be replaced. In a few short hours you can restore the charm of your floor with little to no evidence of any prior damage. Before you begin, make sure you can get new wood planks that are the same thickness and type (usually oak or pine).
