Chosen because they advertised "99% dust free" work, and they delivered. Also did a very nice job of refinishing the floors. All their people were professional and courtious. The only issue is that I was told the "quarter round" did not need to be removed and there would only be minimal damage to it. I was rather sceptical & with good reason. The quarter round around the entire perimiter of the room needs refinishing. It is not a big issue for us since we were planning to paint anyway. Overall, we were quite satisfied with the work.
