The back side of our living room is sagging. The lr is typical front to back. The front is fine, but if you stand at the front of the room and look back, the back molding/ceiling sags in the middle. The master br directly above this room does the same. Below the lr is the basement and it does not appear to have the same problem.
We have called a couple of contractors in and neither instilled much confidence in their opinion. They both want to rip out the entire lr ceiling and replace joists, but neither seems sure of what it will take to fix the problem. It seems to me ( just using common sense and I have no expertise) that the lr would have to be slowly jacked up and the braced when it got level. We are resigned to the fact that the upstairs master bath will probably be wrecked when the ceramic tiles start popping.
Has anyone been through this?
