Cold spot on interior wall
 
In my master bedroom, I have a spot on the lower portion of a exterior facing wall that is exremely cold during our cold Alaskan winters. I can feel around the area, and notice very distinctly where the cold spot is, and where it ends (it's about 1 foot diameter area). It is close to the floor, so how far below the floor itself, I do not know.

I discovered it last year, when running a humidifier and found ice built up on the wall. Removal of the humidifier stopped the ice. I soon forgot about it.

What alerted me about it again, this time, wasn't ice, but mold along the baseboard in that area. I had some clothing and a box sitting on the floor in that spot, so air circulation to that part of the wall was restricted and obviously moisture collected.

I'm kinda torn on how to best take care of this. The home is 20 years old, it has stained wood siding on the outside (typical in AK). I imagine that removing the siding and placing insulation must happen, but what about the inside? Would anyone see the presence of moisture/ice/mold as an indicator that damage has been done inside the wall, and I should replace the drywall as well?

I would start with the drywall. Lets you see whats up the quickest and you get to work inside:thumbsup:

I agree. Remove the drywall and the insulation and inspect what your issues may be. Post some pictures. You are a free air flow that needs to be sealed. Just find it.

Hmmm.

If there's ice, then there's a lot of cold air coming in from outside. I'd start outside and see if I could find how the cold air is getting in.

You'll probably end up needing to pull out the drywall, but I'd still look outside first.

Thanks for the advice. I'll definitely take some photos when I do it.
