Hello, I just recently bought a condo in downtown Chicago. The south side of our unit has a great view of the city i.e. a big sliding glass door that is surrounded by more window. Since the temperature has dropped, I've been noticing a fair amount of condensation forming on the inside of our unit. I expected some of that because of the hugh temperature gradient. However, there is literally ice forming on the inside framing of the sliding glass door. I've have to put towels at the base of the windows and sliding glass door because the condensation has been dripping and ruining my hardwood floor adjacent to the window. I spoke with my building supervisor who said that there is probably a leak and that I have to caulk the outside of the window frame. However, since it's so cold that the caulk will not adhere. That being said, they said that I have to basically deal with the towel solution until it gets warm enough to do something about it. Is this true? Is there something that I can do? Thank you.
