I am replacing the floors in our 1873 home. Currently we have wide plank pine that is original to the house. I had planned on just covering them, but it's making me very sad to do so. There is no subfloor, so they would need to be pulled out and replaced with 3/4 plywood. The planks vary in width from 4 to 6 inches, and lengths are up to 12 feet. Around 600 square feet in the front two rooms, and another 200+ hiding under the stick down linoleum in the kitchen.
The floor was quite nice when we moved in, but has not stood up to our dogs nails (three 50 pound dogs.) It's just too soft. If you have small dogs or no pets I'm sure it could be beautiful again.
It has been refinished (as evidenced by the groove at the bottom of the baseboards), but has a lot of life left in it. If someone is interested in doing the work to get it pulled out, please contact me and we may be able to work something out. I am in the Rochester, NY area.
