I have two vertical house jacks from the local tool library, which I've used to support framing during extensive dry rot and termite repair:
I'm into a section where the house jacks won't work. I need to support, and then slightly jack up, a load bearing double stud to the left of a window. The entire bottom plate is unusable for bearing due to termites, and access is needed to the double stud to complete the work.
Notes: The window corner bears no load (it's empty). All the cripple wall is mostly new with vintage lumber. And yes, that's electrical behind the kitchen cabinets which were built into the framing. A Realtor(tm) arranged for that lovely work.
What kind of jacking techniques are used in situations like this?
