Mold needs water to thrive. If there was a water issue in past, the dormant spores could be visible.

Only way to remove is warm soapy water and elbow grease. Bleach just shocks them into dormant state but could come back with more water/humidity. Mold doesn't always smell.

I would add one of those humidity checkers to the area and check how it compares to.other part of the house. If it's damp in there probably still leaking. GL

Makes sense. I wonder how far up the chimney it runs though. Also it doesn't seem to be spreading, if that means anything. It's been like a this for a few months now

Hygrometer on Amazon. I think they are two for $12.

leave one in there and pay attention to the humidity level during rainy days and in humid summer.

Maybe scrub off what you can reach with soap.

If you are worried about it still. Either spray bleach water in there from the top down and hope to shock the mold.spores that could float around the house. Or get ozone blasted in there to kill the spores. Unless you have a cooky friend with an ozone machine like me you probably need a pro for that.

There's also one non chemical option . It's called benefect and it's mostly essential oils. I hired a pro to apply it in a clients house once. Way safer than the hard stuff. GL
