Wow thats a tough one. I would maybe try replacing the boards that are damaged or chipping.To replace boards that are situated close to walls or moldings, follow these steps:
1. Start by removing the baseboard or molding. Be sure to do this carefully as not to damage the molding, as it is replaced in the final step.
2. Remove the boards starting from the molding until the damaged board is accessible.
3. Replace the damaged board and then the rest of the boards you removed, by clicking them back in place.
4. Replace the molding.
