Yes. A lot a variables. What sort of piers in what type of soil. In stable circumstances it can be as simple as shims, but some types of houses need more "gentle" treatment. One needs to know exacty *why* it's unlevel first.I'm specifically interested in the "means and methods" typically used in the "jacking" process, rather than the finished product.
For instance, how do they set up to make sure you're not shifting the load onto the floor or some other part of the structure unduly? I've seen a very messy example of this and need to figure out what SHOULD have been done in that particular case.
