Beam And Pier Foundation Settling In Two Corners

[Michael Campbell]

Hey Guys,

I just picked up a new 1920's Craftsman and after noticing some slopes in two different corners of the house, I decided to take a closer look under the house. Interestingly, out of all of the inspectors we had come through the house, none really took the effort. Anyway on the one side I investigated I confirmed that the concrete footing is cracked in the middle, and it slopes out to the corner. It looks like someone actually poured concrete on to the crack, but I can't seem to figure out how that would have helped.

Here's the crack:

I'm assuming there is something similar occurring on the other side of the house.

I spoke to someone who can jack the house up and he gave two options - 1. Jack from under the concrete and 2. Jack the house free from the concrete. The second one is much cheaper but I'm not clear what implications I should be considering. Thoughts?
