I have a small cape in Maine with bulkhead door for basement access. Have been thinking about adding an interior door to help keep cold air out of basement, but was told that doing so would cause the stairway or bulkhead walls to crack because of the temperature extremes. Can that be true? Any suggestions are appreciated.
I am by no means an expert - far from it. I have a small ranch with wooden bulhead doors to the basement, 4 steps down to inner door (again wood) with glass pains (this is an old door and by no means as insulating as new doors). I can't imagine not having this door - keeps the basement much warmer.. I've been in this house for 13 years and the doors were there before I got here. I see no problems - however I do have cinderblock and not solid concrete so maybe that makes a difference.
