Your experience with foundation issues?

[Ashley Benning]

I'm looking at an REO property that is a pretty cosmetic flip except for one thing: HUGE cracks in all the cement under the flooring. Apparently this is common in this area as the builder was a crook and did not put rebar in the foundations when the houses were built in the 1960s. I'm going to bring in a specialist to quote the repair work, but before I do that I'd be interested to hear some worst-case scenarios you have experienced. Am I looking at a $20,000 job, or a $100,000 job? Single level slab foundation, 1300 sq ft house

In my area, it's not a question of if, it's a question of when. 

I am in Oklahoma, so things will probably be cheaper. I am getting about 500/pier and depends on the sqft for foam injection. Depending on how bad the cracking is, it may be better to re-pour.

I would get an engineer's report and then ask any foundation company to quote on that report. You may be letting the fox into the hen's house.
