There are many different types of repair that wood floors might need over time. Scratches can be fixed by a light screening or sanding. Wood can sometimes buckle because of water or environmental damage. In extreme cases wood floors may be ruined due to structural damage and have to be completely replaced. Often times most wood repairs can be fixed with patching the bad areas with new wood and blending in the old with the new using a new finish.
Our experience will matter in these types of scenarios.
