Question DetailsAsked on 1/20/2020

Do I need to remove flooring to replace a rotted joist in a crawl space

I just bought a house in New Jersey - 1960 split level. There are 4 rotted joists that need to be addressed in the crawl space that is beneath the mid level. It looks like dry rot based on what I found on line. I am planning on cutting out the rotted section( plus some) of the old joists (original) and replace or sister them with new ones. So:

1. Should I completely replace the joists? Or Cut out the rotten parts, replace and sister? Both sides of each joist? Is dimensional ok? Or should I use a laminated I beam?

2. Can I do this all from below? My father in law brought up the concern that the new joists would not be attached to the sub flooring by anything more than construction glue - the flooring above may warp, cup, etc. He is suggesting that I rip up the flooring (1 inch wide oak that admittedly needs to be refinished anyway) to expose the subfloor (TnG 3" wide hardwood) so the sub can be nailed to the new joists. Overkill?

Other Thoughts?
