Condensation running down my range vent into my microwave in cold weather? (And cracks in ceiling)

8. Thank you. :^) We are definitely going to try to wrap the parts we can reach, and I want to

remove the older loose insulation around the pipe, the greasy stuff, with a new bag of fluffier stuff. Hopefully those two things will help.

Interestingly the only thing that came up about humidity from the builder/seller was that we need to run our bathroom fans at least 20 minutes after each shower, otherwise we would run the risk of mildew and mold due to moisture being kept in. (Younger son has literally made it rain down the walls a few times when he has taken hot showers in a cold bathroom.)

I often have condensation on the windows in the house during the spring and fall when the temps change faster than the humidity drops. Do not have this problem in summer or winter.

I have a hygrometer that I move around the house to check on things. My bathroom is often between 60 and 70%, which I think is too high. Lately, it is at 55% or less. We have a new pellet stove, which is drying the air out. The great room has been under 50% a few times when I have checked it lately. It will be interesting to see where it lands once we get into the deep of winter when the air is at its driest. I may have to do something about a humidifier then, or at least put something on the pellet stove to keep things a little less dry.

Still, the wetness of the insulation in the attic between the two boards that make up the beam concerns me. When I noticed the problem last spring, instead of being like this || they were more like this )(.
