It happened. The chimney is through the ceiling. Tomorrow they plan to take it through the "attic" and up through the roof.
I don't know. NOAA predicts the high at MINUS SEVEN. They can't really work from below. That means that they have to work up on the roof. No real sun either. That's what saved us today. Solar gain.
I hid out in the basement sewing most of the day. That's my plan for tomorrow. Otherwise I will be fretting about frost bite and wind chill.
