Is this discoloration a problem?
(lemmy.world)
Renovating the bathroom and found these dark patches in the joists and roof lumber surrounding the old vent pipe. The PVC part is new.
Anything bad here? Anything we need to address?
Uhh.. is it legit to just cut thru beams to put in piping? Over half of those beams are cut thru. I'd ask about that as well. I can't tell where this is, but if the plumber cut thru load bearing beams to put in plumbing that might be an expensive fix.
