Remodeling my 1st floor powder room. Gutted everything. The floor is 3/8" plywood subfloor. Wall plates etc built on top of that. Then there is a layer of 3/4" particle board. On top of that was 1/4" plywood underlayment that had the vinyl flooring on. I pulled the underlayment off easily. When cutting out the 3/4" particle board with my sawzall, I cut into the 3/8" plywood in a small area. The cut is between and parallel to the floor joists (16" oc). Do I need to worry about this since I will be putting down 3/4" plywood over top of it anyways? My guess is that the 3/8" plywood subfloor is simply a "spacer" to help the vinyl flooring match up to adjoining hardwood floors?
