another unlevel floor problem

(sorry if this is a duplicate post)

We want to install hardwood floors in two rooms of our 1920's craftsman house.

Problem is there is a bow in the floor because two floor joists at the wall are in a different plane. If I lay a straightedge on the floor I see that the floor dips 3/4" in 32".

Leveling compound is out because our whole house is not level and we don't have the time or desire to lift the entire house and install a new foundation. The existing floor is also 13/16" x 8" with 1/4" gaps between them so the leveling compound would end up in the crawlspace.

Here is my plan to fix it, please comment:

- cut out the 32" section the length of the room just to the inside of the floor joists (so the old floor still has support)
- sister in some 2x6's or 2x8's to the joists, setting them higher so they are in the same plane as the rest of the floor
- screw and glue down 3/4" plywood

Sounds like a good plan to me, keep in mind though that when you do this it may create issues with the transition to adjoining rooms/floors. Best of luck to you and oh yeah welcome to the forums!
