The original floors were badly damaged by insects in some areas so in order to save them, we needed to have the most badly affected ones removed and replaced. The lesser damaged boards could have the damaged bits dug out and then were puttied. All floors then received a final sanding, then a stain prior to final coats of varnish in order to help balance the color contrast.
Here is our carpenter Fred (real name Patrice) replacing boards that had been severely damaged by insects. These floors had been covered by carpet, so the damage was not visible when the house was inspected. Had the damage been determined to have been termite, the cost for repair would have fallen under the insurance binder of the house inspector.
