Our 1920's semi still has the original floors, and they have been sanded down and refinished so much that there isn't enough wood left to sand them down again. They were getting stained and worn, but we're not ready to replace them, so I called TipTop for a consultation.
Andrei came by the house to have a look, and he said they could clean off the old finish and put on a new coat of polyurethane without sanding down the wood at all.
He also said it would be possible to only refinish the high-traffic areas, and not worry about the floors which are covered with rugs or heavy furniture which we never move. That made me happy because I didn't want to have to move all my furniture to who-knows-where for a day! We just shifted stuff from the floor onto the carpets for the day.
The day of the refinishing, Andrei and the guys helped move some of the bigger furniture before we left. Andrei texted me to let me know when they were finished, and what time it would be safe to come home the next day.
When we got home the floors looked fantastic - clean and even and shiny. There was hardly any dust, and it didn't smell too much. There's a bit of a new-house smell, but I'm still kind of enjoying it. (Better than old-house smell!) The only drawback is I've turned into one of those "take your shoes off!" moms.
I'm still really happy with the floors. I've started walking around in bare feet so I can enjoy my beautiful floors with all my senses!
