Our contractor was supposed to be done in Nov.it is now Jan. and is not half way complete.

Sounds like you need to start pushing this fellow.  Ask for a sit down and for a specific schedule that gets you to completion.  Bring your insurance company into the conversation -- they may be able to offer some suggestions.  Review the contract for the work.  does it comply with the home improvement consumer protection act?  if not, that might give you some leverage with the contractor.  if those things fail, you could file a complaint with the attorney general, better business bureau or fire the contractor and bring in another to get the job done.
