What Kind of Hardwood Flooring Do I Have - Chicago Home Mid50's
What you have appears to be a red oak 2 1/4" strip floor. It will be 3/4" thick. The plywood you see will perhaps be 5/8" thick, and hopefully on a subfloor as well as the red oak. You will need to confirm all this, and can be easily done if you have an unfinished basement. Looking up from the basement on a 1950's era home you should see diagonal subfloor with the nails holding the finished floor poking through. If you see the underside of the oak flooring, then there is no subfloor and the task of replacing the floor gets a lot more dicey since the joists will be the only thing to walk on after the tile and plywood is pulled up. The subfloor should be there, if this was on the second floor, there would certainly be a bigger chance of no subfloor.
