Inspector Paul inspected a 122 year old home recently. He discovered bowing walls of more than an inch and the wall is actually moving out. There are a number of temporary support posts. These temporary posts are meant to be put in place before permanent posts and beams can go in.
There are temporary posts they don’t sit on footings, and you can see that these posts have pressure on them that they’re even cracking the concrete. In one case there’s so much pressure that it’s actually pushing in and settling. There’s a large crack in the joists so that is one of the reasons why the floor is sagging upstairs.
Paul will recommend a structural engineer review the basement for further evaluation.
