It sounds to me like the contractor violated the Home Improvement Consumer Protection Act by failing to give you a signed agreement that contains all of the provisions required by the Act. The fact that he violated HICPA probably gives you some good negotiating leverage. One consequence of violating HICPA is that you can void the contract. A solid letter from an attorney identifying his obligations under HICPA, where he violated the law and the consequences of those violations would probably help you get to a resolution of this matter.
I recommend that you seek out a local attorney for a more in depth discussion of the matter. I do not recommend that you take any action steps without such a consult. Act quickly because by waiting, you may lose certain rights and remedies available to you.
