Welcome back Jeremy. Your thread last week ended with David offering to help you out. He is a contractor and has experience in structural problems. To recap, you have a brick foundation in a 50 year old Chicago unit that has severely deteriorated. Previous owners installed a frame wall under the house along the foundation, and the settling is causing that frame to be buckled. I responded that you may actually have some legal recourse. You were also informed of some possible low interest Federal loans.
Now, what are the contractors telling you needs to be done. Their findings will help us to advise you.
