Hi all. I've got a corner room in my basement that currently has an old vinyl/linoleum over wood floor. That is on top of concrete. I'd like to put a new floor down right on top of it -- something like DMX and then cork or something else. The basement is musty but never floods. The floor is a pretty sound surface at present but God only knows how long it's been there and I'm a bit concerned by the old wood top, along with the sleepers they sit on. As that wood continues to decompose, is that going to create a permanent mold situation? Tearing up the old floor would be a colossal project that I'm really not relishing at the moment. Thanks for any advice.
