Walls damaged from foundation problems

[Nick Smith]

Hey all,

I recently bought a single family property that in the past had foundation problems.  Those problems have all been taken care of, but the cosmetic damage to the walls is still present.  At some places the cracks are a quarter inch thick.  There is also one wall that has separated.

In your experience, is it best to put up completely new sheetrock where the back cracks are, or to just patch everything?

Also, the foundation problems damaged the garage door to the point where it won't work.  Does anyone have experience with this?  How hard of a fix is it?
