I just moved into my boyfriend’s house that he bought in late 2022. Noticing all kinds of cracks in the ceilings and walls, plus lots of uneven floors. This one is the most concerning to me - it’s in the living room ceiling, which is below our bedroom. I believe the crack is along where the previous owners put on an addition to the house, as in there was an exterior wall here in the past. I also noticed the floor above seems to dip at the same place. I’ve been nervous about sleeping above it or hanging out in the living room, but my boyfriend insists it’s nothing to worry about. Is it an urgent concern or is he right?
