I am in the process of purchasing an older home built around 1950. There are hardwood floors under carpeting that I believe are original, but when looking at the home, I could only check a little of it (couldn’t pull someone else’s carpet up) so I don’t know lot about them.

My question buy medicine online is, how do I know if they have previously been finished? Also, how do I know if I need to do the full blown refinish of the floors with the large floor sanders or just need to refurbish the floors? I have read and heard from different people that doing the floors yourself is difficult – is this true?

And, the room I am thinking of doing is about 225 sq feet – approx how much would it cost for a professional to come out and do a room that size for either refinishing or refurbishing. And, would it be worth it for a professional to do it?

Thank you!
