Mine are pretty worn out and need to be redone bad. I want to sell my house and if the floors were done that's one less thing a possible new owner wouldn't have to have done. And I'm a little unsure if I could do them and not mess them up..
I have known people who have refinished hardwood floors before. They said it was not worth the effort to do it yourself. It is tough time consuming work.
I saw the room that my cousin refinished himself and it looks alright but the rest of the house that was professionally done looks 100% better.
One thing to consider, if the floors mainly look dirty and there isn't alot of scratches you can try getting a good wood cleaner.
There is one particular brand I am thinking of that I used while I worked at a furntiture store, it would clean the worst wood and make it look brand new. I can't think of the name off the top of my head but it was part Mineral Spirits and part wood conditioner of some sort. I was a milky white color.
You have to make sure you wipe it all off becuase the Mineral Spirits will eat through the finish if left on to long.
But basically its just a spray on and wipe off product. I think it cost about $50 for a gallon or so, and that gallon would go a really long ways possibly could do the entire house.
It might be worth a shot, could save you alot of money and just make the floors look a little newer if there aren't a ton of scratches.
Yeah, I should be able to give you some info later today. I know one guy who owns a company called Straight on Hardwood Floors. His name is Pat Ledwein, I will look for his number for you. Straight on Hardwood Floors 651-470-8056
