Here's a couple dumb questions. I have neglected my showerhead for a while and the hard water ended up clogging a few streams and now my baseboard near my bath tub is rotting. I am assuming the wall is also molding but I am too retard to rip it off and check it. Should I just nail the shit down or buy some new sheet rock and attempt to patch the area before installing a new baseboard? Other q probably a bunch of qs but some of my ducts are blowing a lot of dark dust/dirt and there is some build…
