I need to remove and replace part of a subfloor that is glued to the floor joists. What is the best way to do this? Can I simply cut the plywood flush with the edge of each joist, sister in new joists, and then attach the cut out subfloor sections to these new sisters? If not, then is there a good method to remove the sections glued to the floor joists so I can attach new pieces of plywood?

Thanks,
John
