I have a 1920's Victorian house that seems to "develope" new cracks when it goes from hot to cold in a short amount of time. In the South, that is a few times a month sometimes. Is the dramatic temp change causing it? The foundation and all look good and no noticable sloping. The ceiling started cracking around a old painted over attic door. The wall cracks seem to follow straight lines where different parts of the wall meet.
thanks for any help.
