It appears to be reclaimed softwood (barn boards or beams re-milled into floorboards). No way to tell what kind of softwood, but it is so light in color that I'd take heart pine/yellow pine off the table. Which leaves spruce, white pine, light fir, larch, etc. Casey

Yep, definitely oil finish. Can't see any scrapes, though. Reclaimed boards from a previous project? Seems like it.

Thanks Henley. My sister-in-law has the same floors in her beach house, too, although she mixed chestnut in with hers. My husband's company made them for us (Chestnut Specialists Inc.) They run about $12 sf for that width, not including installation and finishing. You can find new oak for about $5, so it's definitely a bigger expense. I like the look of the oil poly we used, but there are more durable finishes out there. Our dog doesn't mark up the floors just walking around if we keep his nails trimmed, but running around corners when the nails get long has caused some scratches. The distressed nature of the floors helps hide them though. And he's just toooo cute when he gets running, LOL.

If this is an upstairs room, it could easily be pine, downstairs would normally have white or red oak, as my 1908 house does in Ohio. Type of wood depends very much on what is local the older the house is; my suster's current house (a farm built around 1850 or so) has joists in the oldest parts that are half-trunks and a rubble foundation. She just told me that a previous owner had all the walnut woodwork removed some time ago, but here is the big surprise: the attic rafters and beams are all walnut! So are all the 12" or larger sheathing boards for the roof! Apparently that was the type of trees growing in the area at that time northeast of Columbus.
