What I have here is an interior closet. We got stuff growing our joints connecting to this system. It's actually worse up here on the floor piece. I went up here and if you look at how they did this, you can see when they installed the unit.

You have your ductwork coming out of the attic and then this gap right here. It's just tape and then solid. Don't worry, you have a good four inches just tape and it's a ring all the way around that will get really cold and cold enough. That any moisture in here it's gon na condensate on that surface, any dust it's gon na hit that and you're gon na start growing.

So it's a clothes closet where that moisture and dust is coming from. We need to be found as well Matt right here straight up into the attic behind both of these. We got warm dusty human attic, air, meaning a really cold surface and condensation and growth. So the solution is going to be to replace this four piece of here and then seal off any any gap to the attic.
