A short instructional monologue by Derek Cole explaining that wet duct insulation is typically caused by moisture from the crawl space. The speaker warns against temporary "band-aid" fixes, notes that wet insulation cannot be reliably dried or restored, and recommends sealing the crawl space, replacing wet insulation and affected duct sections, and installing a sealed duct system to prevent recurrence.
People try to put band aids on the problem and don't try to fix the problem. Right? I mean, I go to the doctor. I want to be healed of the sickness. I don't want a medicine to mask over the symptoms of the sickness. Does that make sense? So I want to. I want to cure. I don't want the band aid. I want to stop bleeding. I want to cover it up. So we need to figure out why the water is getting in the duct. To start with, it's probably because the crawl space is getting moisture coming from the ground and it's getting wet that way. But once that happens, that needs to be replaced. Once you get insulation wet, there is no drying. I mean, you can try to dry it, but it's not going to be completely the way it was. So you need to go back with a new duct system, a sealed duct system. And you need to handle the problem of actually the ductwork getting wet. So seal the crawl space, and then you need to replace that piece that is wet. Because wet insulation, first of all, stinks, and second of all, you don't know what is in the insulation. You can't completely dry that.
