I have a 140 year old house with a mortared stone foundation - some walls are stone right up to the sills and some are stone below grade and brick above grade. One side of the house has settled 4" over the last century - we suspect undermining from roof runoff. (We plan to improve drainage this year.)
Setting aside the concerns about DIY house jacking for now...
Is it possible to level a foundation by jacking the low sides to just above level, and using lumber and/or mortar to fill the tapered void that my jacking created below the sills. I'm guessing that with a house this old, there is nothing other than the old mortar holding the sills onto the foundation. If that's the case, it doesn't seem that my "shimming" would make things any worse.
I don't think I want to bring the house up more than 2" - that seems like enough trauma to do to the house, even if I go slow - I don't feel like refitting any windows.
