I'm working on a house that has no sub flooring 4x8x3/4 it only has hardwood flooring down and then the walls where built and a house was produced. The outside deck is screened in and it is rotting now. I've inspected the 2x8 floor beams and it appears that 5 of the 2x8 beams are rotted and need replaced and the hardwood flooring is gone as well. (What would you suggest seeing that the HWFloor runs all the way across the house from left to right, front to back. I'm needing some opinions on how to start my project. HOTROD
