My mother's house was built in the 1930s and underneath long suffering carpets lay some sort of wood floor. The subfloor (at least I think it is) sits on top of the joists at a diagonal and the mystery floor boards lay on top. Perhaps glued or nailed, I'm really not sure.
I need to know what kind of floor it is. My Dad said it was some kind of pine but not the 'good kind'; he seemed to think it was cheap floor and it could never work on its own and needed to be carpeted. Something about it being "soft wood." I'd ask my Dad about it but he passed away and know nothing about wood floors. I really don't have anyone else to ask about this issue. And while he was close to perfect in nearly every respect in my eyes, he could have been wrong about the flooring and it's unsuitability. Are there any tests I could do or something? Can you tell just by looking?
There are problems with the floor anyway that need to be attended to but knowing what kind of wood it is would really help me make a plan.
