Old home hardwoods directly onto joists

I have a 125 year old house in mo and found on the third floor there is 1 inch thick x 3 and 1/4 tongue and groove (oak???) under the carpet that I removed in one room. I assume this runs throughout the third floor under the carpet. The floor runs the opposite way as the joists and is nailed directly into the joists with old square head long nails. I have to replace a couple broken boards but otherwise the flooring would look good after a sanding.

Since its on the third floor and I don't have the moisture or temp issues, am I ok with refinishing it or could it just be an old subfloor?j

Welcome to the forums!

It's probably the sub floor. A friend of mine had an old house that had an oak sub floor with oak flooring on top of it. They had a heck of time cutting thru it when the HVAC system was installed.

While it might be feasible to finish the sub floor, how do you intend to replace the bad boards? not sure where you would buy T&G boards of that dimension. You might also find that the boards aren't as tight as you'd like for a finish floor. You'll know more after the carpet is removed.

Update

Carpet removed. There are a couple of spots with a 1/8 of inch or so spacers between slats. I planned on trying some salvage places for the replacements. I would hate to cover up such nice looking wood if I could avoid it. Anything that could be put in the spaces between the boards prior to sanding? The website seems like a great reaource!

Do you mean 1/8" gap or actual spacers between some boards? if the latter, what are the spacers made of? There are oak fillers that can be used to fill gaps although 1/8" with no backing behind it would be marginal at best.

Size:  42.0 KB let me know what you think. I would hate too cover it up if it would work but don't want to waste my time if it's not a good idea. I have a small concern that it will make it much colder in the house by removing all of the carpet also.

My concerns are similar to Marksr's in that finding matching wood would be problematic. The floor will probably sand down nicely, but your repairs may show up pretty radically, since you won't be finding 125 year old wood to make the replacement with. Of course the new boards will have to be face nailed and the tongues and/or grooves modified to make installation easier.

Nice modification on the saw cord, too Just for safety's sake replace it.
