My house is located in Bergen county, NJ its a bi-level with crawlspace type. My first floor is crack free, my second floor has cracks from the corners of interior door jams going diagonal. Also it appears the ceiling cracks are at sheetrock joints. The house is 20 years old. We have been living in it 10 years and the crack Ihave tried to fill over the years but they keep coming back worst in the winter.
