I attempted to sand down the hardwood floors in the dining room, living room, and hallway in a home I had just purchased, using rental equipment. I was unable to completely remove the old finish, so I brought in Mike to take a look. He gave me a quote of $625. Later, he called and said he had an opening, and that he could do the job starting that day for $50 less, and we hired him. Him and an assistant went to work. He didn't finish that day, but before he left, he walked the floors with me to find places where holes/dents needed to be filled. His assistant finished the next day. He said the old finish was tough, and it took him more paper than normal to get the job done. When he was done, the finish was all gone and the floors were ready to refinish. He offered to do the staining as well, but I told him I wanted to do that myself. Nevertheless, he offered staining advice and answered a few questions I had.
