I’m am doing an extensive first floor remodel of a 1970s two story home. Part of that remodel included updating the homes staircase.
Originally the stairs were painted white. The customer wanted the threads returned to a natural finish. When we sanded the wood it was discovered that there was quite a bit of old damage. In particular the areas where the old spindles attached to the threads were unsightly.
The owner did not want to spend the additional thousands of dollars necessary to replace the staircase so I came up with a partial solution. I routed out the old damaged areas and replaced them with new wood. When the stairs were sanded and stained they looked considerably better.
Are my patches invisible? No. However, the staircase looks significantly better.
