I have a massive 1890 historic home project that i'm undertaking, and
one of the core issues is that the floors slope dramatically, and not
in any one particular direction. We're going to be removing the
majority of the existing finish floor (no historic value), and putting
in a new subfloor. Couple questions:
1. What is the appropriate thickness of plywood to use as a subfloor
for hardwood?
2. Should it be glued and screwed, or just screwed?
3. If an outside contractor is performing this work, what is a
reasonable average price per sft for demo of existing floor and
installation of a new sub-floor, assuming that there's at least 3500
sft?
Any help is mcuh appreciated.

I would suggest getting a handle on the cause & remedy of the floor
sloping.....this sort of thing usually points to foundation issues.
Active or dormant? recent / ongoing / old?
This need to be done before you worry about R&R of the subfloor.
btw what's your joist spacing? previous subfloor sizing?
What's wrong with the subfloor that you're thinking about replacing
it?
cheers
