    Hi, I have a 1920's home with narrow (1.5 in.) Hardwood floors. In places I'm getting lots of flexing and creaking, and I expect that its due to the narrower boards, too many end joints too close, and some failure of the underlayment. My plan is to come from below with 3/4 plywood cut to fit snugly between the joists and cleat that in place with 2-by pieces standing on end. Thoughts or suggestions? Liquid nails as well? Thanks! MM

    Not a bad idea. You could just glue and screw it up to the sub floor if you think the subfloor is thick enough.
    Not sure you need it but you could add a 2x2 on each side screwed to the joist on an angle so it pulls up to the floor tight.

    Since you seem to have access from below, have someone walk around upstairs while you are watching from below. I would be looking to see if the joists are flexing.
