Let me make that great wood floor beautiful again. I will come to your home, seal off the area to be work in, remove the offending previous mess of a paint job/stain/vinyl floor/bad taste that the previous owner left on your hardwood floor, bag it up in hefty garbage bags, and remove it. That's step one.
Then for step two, I will complete the removal of the said nastiness from your soon-to-be-lovely floors using the tools at my disposal. Note: I do not use bad chemicals on your floors or in your home. I never use them in mine; why would I use them in yours? If I use paint removal compounds, they are strictly "green" and government approved to be so.
Next, my favorite part - sanding. This is where my sealing off the work area really pays off for your home. It is also where I don the ventilator mask and eye safety protection mask that my kids tell me makes me look like a bug. But sanding is the first real step, to me, to seeing the character and warmth in your floors that new floors and laminates just can't hope to duplicate. Ahh, I love my work. The wood gets four coats of sandings - coarse, medium, fine, and steel lamb's wool - before I even think about staining. After I stain, the floor gets another rubdown with steel lamb's wool, just to make it silky to the touch, and if it needs a touch-up with the stain, it gets one.
Next stop, staining. Lots of people with pine floors don't want to stain, which leads the wood to get a nice, warm, reddish glow over the years. It does, however, make the floor harder to keep clean [natch] over the years. My floors are pine (my house is over a hundred years old), and my husband preferred an oak stain. I scratched my head, but I went for it. I have to admit that it looks great. So, score one for the husband.
There's a lot of debate currently on whether or not to seal wood floors. I will do this if you want me to, but personally, I'm against it. Floors that are sealed up are, I've found to my sorrow, floors that dry up and can crack. You are much better off not sealing the floor, but brooming the dust off of it weekly, or swiffling it weekly. Once a year, rub it down with (brace yourselves) olive oil. Yep, good old-fashioned olive oil, with maybe some lemon oil mixed in for fragrance, will do your wood good. Forget the expensive, fancy-schmancy stuff you can buy online. Olive oil - that's the ticket.
I go for the natural treatments of wood, and of other things, as much as possible, not only because it's the best for the living things in the household, but because it works best.
I don't give price estimates online, because I like to see what I'm working with first. What I do is refinish a free twenty-by-twenty-inch area of your floor for free. Gratis. Nada. You pay nothing. Ever. I like to see what I'm buying, and I like to treat the customer like I'd want to be treated.
That is my way to giving an estimate. If you like what I do, I'll finish the floor. If you don't, we part friends.
I hope to hear from you soon. Let's get that floor of yours looking good and feeling great under your bare toes.
