Ok so going a step further. Here's a little tutorial of mine for you.
Say you want to go buy some hardwood. That would come from a store like ours.
I do not believe that a Home Depot type store would handle any hardwood planking for flooring. There are a lot of discount type places such as "Lumber Liquidators" that handle it also, but you run a very high risk of getting twisted and warped, nasty bad wood from places like those. So to be sure, you should go to a quality flooring supply store.
First you need to get under the house with a moisture meter and be sure there is no moisture coming up from under the house that will cause your wood to pop up or warp. We won't touch a house that hasn't been mosture tested first. If the meter is reading moisture, that problem has to be solved first.
Back to the wood
You'd probably want oak. Red or white, not that much difference. Anyhow, it comes in grades.
The best would be Select ( also called #1) which has no knots (the most expensive)
Then the next lower would be #2 which has a few knots (less expensive)
And then you would have Cabin Grade which has lots of knots and veins. Cabin grade is your least expensive and a lot of people like that because some people feel it shows the integrity of the wood. Sells good here because there are so many log cabin type homes built. I like it because for an old mountain home like this it would look appropriate.
Then it has to sit in the house and acclumate for a little while. It will expand and shink a bit with the weather changes. Once it is down, it gets refinished and that means lots of sanding. We have a ton tied up in our sanding equipment. It's the best on the market and as we sand, it is sucked up so not that much dust, but some. If you rent the equipment, most likely it's crappy cheap equipment and you run a good chance of making "digs" in your wood with it, wrecking it. After the refinishing, then there is the stain or color you choose and you must evacuate the house because the smell will get you sick usually, if the stuff is of good high quality. And then afterwards the poly.....we usually use three coats. One coat a day as long as it's drying nicely in a day's time, we can add another the following day.
And that is what it takes to put down a ruff floor if you go with real hardwood.
There you go!
I'm pretty good at this huh?
I'm so good that is why the store is named after me too! hehe
