I seem to be allergic to something in my bedroom floor (possibly mold)l I want to rip everything out, down to the joists, and start over. What's involved in putting down new plywood over the joists? Is this totally out of the league of a beginner? Liz

I gotta do that to my bathroom and kitchen floors too. I may even need to replace parts of the joists. I won't know until I rip it all up.

Someone I hired long ago to fix my bathroom floor replaced the subfloor around the toilet with pressboard! I told him I didn't think that seemed like the thing to do. Well, it's all yukky again because it wasn't firm enough to keep the potty from rocking.

Is this something a do-it-yourselfer can do?

the moment you start pulling up your subfloor you are removing a structural element of your home. Non-load bearing and also loadbearing walls may be plated on top of your subfloor.

First answer, it depends (can a first timer diy'er do this themselves). Some areas that require building permits and code inspections for work within the home even certain projects done by homeowner, do require a building permit for this project.

Second answer, I don't recommend your ripping out/replacing subfloor yourself without guidance/advice from a bona-fide expert who has examined your situation. and if doing I'd go one area at a time, remove one sheet, replace a sheet, move to adjacent area, remove/replace.

This much I know for sure, if you have wall framing on top of the subfloor you mustn't cut it up to that point and just replace/abut the subfloor to this area.

The sub floor acts like a web between those joists distributing sheer forces, torque, twist, load, and the like. Being an important structural aspect of your home its on the same level as like a header, a load bearing wall, etc.

i'm gutting the entire second level of a dormered cape, and need to remove the existing rotted subfloor. although small sections still seem ok, i just figured i'd replace all of it. because all of the interior walls were non-load bearing, i've removed them. so i basically have one large open space stretching from gable to gable.

i don't quite understand why i can't leave the existing subfloor underneath the exterior wall's sole plates (these portions of subfloor are still good, not to mention impossible to easily remove), and lay/abut new subfloor up to this point. even if the subfloor does act like a web between joints, wouldn't the new subfloor provide the same structural support once it's screwed down?
