First of all document all conversations and if the contractor has an email account, start doing all you can on email with follow up emails restating what you had verbal discussions about. Then you'll have the record of your part & his part of conversations. Sending a registered letter with return receipt is a good idea also followed up with an email. I'm not really up on liens, but I think I remember that suppliers and subcontractors can place a lien on your property if the contractor doesn't pay them. If there is a clear delineation between the good part and the bad - example: one half good, the other half bad, maybe they can tear up the bad part, put in an expansion joint, and replace that part. Sticky stuff when you get into situations like this. Do all you can to protect yourself. Also, any paper work, invoices, receipts, etc. you should have copies of from the suppliers, contractor, etc., make sure you get those.
