What could cause a home's floor to sag?
Nov 27, 2015 1:00 AM - Q. The house we are buying has a sagging floor in the living room and dining room. When we asked the Realtor about this, she said that settlement is common in homes that are this old (built in 1944). This doesn't sound right to us because our current home, built in 1904, has no such flaws. The rest of the house we're buying seems to be level, and there are no foundation cracks in the basement. So what could be causing the sagging floor?
