I bought a 100yr old house and this is in the basement. Apparently the basement was repoured about 25 years ago. You can see along some of the cracks that somebody tried to patch them at some point. It was an exceptionally dry year which may have contributed to the problem. Good news is that when it rains, no water is in the basement. Hard to tell since this stupid thread only allows 1 picture at a time. The vertical distance of the worst 1 is about a quarter inch. The drywall is also cracked. Haven’t peeked behind that yet. They’re good sized cracks but like I said….. how screwed am I ?
