My wife and I are currently looking at purchasing an older home (1928) from within our extended family. One of the issues we'll be facing is a leaning garage. It looks like when it was originally built, the only concrete used was just under the walls to build a foundation, and I imagine it had a dirt floor to begin with. At some point, someone filled in the area between with concrete. Well, it appears that water must have gotten between the poured slap and the wall foundations and caused the wall foundations to "tilt" outwards due to expansion in the winter, causing the garage to tilt. It has gotten to the point where the garage doors are very difficult for the opener to open due to the tension. Is there a way to pull the wall foundations back plumb? Otherwise I don't imagine the garage standing up in 5-10 years. I currently am five hours away from the property and do not have images of the issue. I can draw up something in photoshop if there is confusion as to what I am dealing with. Thanks!
