Our solid red oak hardwood floors were refinished this week after a water damage incident. We used a contractor on our insurance company’s preferred contractor list. They sanded and stained the floors and applied two coats of polyurethane. When I looked at the floors there were a few areas that didn’t seem to take the stain, puddling of polyurethane in a few areas, tons of sander or edger marks (some the shape of rainbows and others resemble fish scales if that makes sense) especially near the walls in closets and pantry, areas where there were little bubbles in the poly and some circular marks in the polyurethane. I met with the contractor and he had the crew do a screen and coat. They also tried putting tinted polyurethane on the light patches which did not help. The pool of polyurethane was a bit better but was still there so the did another screen and coat on that area (it was a landing on the stairs so it was a small area). The bubbles and circular marks are better. I had asked that we have 3 coats of polyurethane so he did agree to that. Problem is, after all of this we are still left with the sander/edger marks and a few light patches. Our insurance company guarantees the work for 5 years. I am scared though to keep letting these people have another chance at my floors! These floors have already been sanded and refinished twice so now 3 times....how many times can you sand floors? May be I am being too picky and should just live with it? We have moved back in and not had our final walk through and I don’t want to be nitpicky but at the same time I don’t want to settle for substandard workmanship. I will try to attach photos below. Thanks!

You could call another local floor contractor to get an estimate. My aunt had problems and her floor was sanded again by the same company. The insurance company had to replace the floor because it was sanded too thin the second time. A stained floor should not have sanding marks that are pronounced as viewed from a standing position. This problem should have been taken care of before the first coat of finish.
