Century HW floors has refinished and repaired three rooms in our house so far. All of the refinishing was done on original 1955 HW floors. They have also done a couple other houses on our block which was how they were recommended and we were able to see their work in person. In two rooms, we also had some repairs needed (moved walls, water damage) and they did a great blending job by replacing the affected slats. We can't tell where the repairs were made, it's that attention to detail which impressed us. Pricing is very reasonable especially in our case with our odd slat width (2", they had to cut each slat individually down from 2 -1/4" oak stock). My only issue with them is that it's hard to get them to commit to a day to quote and do the work. But when you do get them there, they are very pleasant and completed each room in about a day and a half. (sanding, prepping cleaning and varnish drying time). They also install new hardwood floors according to their business card.
