Here is a sequence showing board replacement in an old fir floor that needed refinishing:
This is a sequence showing a water-damaged portion of floor that needed replacement. In this case, the new floor boards needed to be “laced” into the undamaged portion of floor. After sanding and finishing the floor, the replacement is nearly impossible to detect.
We have been involved in remodeling projects that have beautiful old oak floors, but walls have been moved, fireplaces re-located, heat vents and cold air returns abandoned and re-located else-where in the floor, new areas of hardwood added, etc. — in short, very extensive repair work. When the floors were done, it all looked new and fresh. This is something possible with hardwood floors that is either difficult or impossible to do with other types of flooring material. American made hard-wood flooring has been manufactured to the same exacting dimensions for over 100 years, so it is usually possible to make repairs to an old floor with brand new material.
