House built in 1982, got water behind the tiles in the bathroom which were adhered directly to drywall. I ripped the tiles and moldy drywall out, and am trying to determine if I need to replace the insulation as well. Attached photos show what the insulation behind looks like.
My initial thought was that it is moldy, but after reading around a bit I guess it’s somewhat normal for insulation to end up like this because of dust/air moving through the insulation. Any idea which I’m dealing with here, or how I can determine for sure?
It’s an exterior wall if that makes a difference, and there is a window on that wall. The wood looks fine to me, just a bit of black which you can see in one photo (the other darker black is tar I think?). So I’m thinking the moisture never made it through the vapor barrier which I’m hoping is a good sign.
