Just call the insurance company that you were insured with before. They can just reopen the claim. Whoever handled the claim the first time didn't do their job. There is a statute of limitations for property damage in Colorado, but I don't remember off the top of my head what it is. Did they just send you a bill, or were there pictures with an itemized list of damages?

Also, underwriters only speak with people in the insurance industry, they don't talk to the public. 10mm-man meant your claims adjuster.
