The home I'm renting for my business was originally built in 1937 with hardwood floors. When I turned the home into a business, I gutted walls, I removed walls, and I also removed the bottom-plates that were nailed to the hardwood floor. B & G sanded and put a finish coat on the floors and it looks 99 percent better. It looks fine, and they did it within a couple of days of my original phone call. The price was reasonable too.
