How do I know if my wood floors need to be refinished?

Q: How do I know if my wood floors need to be refinished?

A: If the finish is worn off and the wood has become grayed and discolored, they will need to be fully sanded. If for some reason, a polyurethane coating is peeling off, it will need sanding. If you have a large dog who has left many deep nail impressions in the wood, the floor will need to be sanded if you want to get rid of them.
