Thank you for the responses. Do you know what type of lawyer I should look for? My lawyer is a finance guy and charges obscene rates and i'm assuming a local lawyer could handle this.

I also can tell you that the pool company has a number of jobs and doesn't appear to be going out of business at all. Amazingly they did a number of pools i've seen and they didn't have the same problems. I also know they all went with cartridge (other than 1 who went with DE and the pool company did the same thing with them on switching it after inspections and telling them cartridge was better, cancer stuff, etc), didn't have a lot of concrete and they all had more typical black soil.....
