@Gail W. I feel your pain. I custom built my house and even after having an air tight contract, I had to fight with them (and give in a bit) to get a contract release so that I could convert my construction loan to a permanent loan.
Would need to understand your situation and chronology to understand where you stand.
- Did you have a direct contract with each contractor? or Just with the main contractor?
- When you replace the cabinet contractor with this guy, did you give him the insurance paperwork? For insurance work the contractor has to agree to completing the work for the approved amount, or you have to agree to cover the overage. If you did and he went over then you can hold his feet to the fire. If you did not share this then you might have to pay, but not always.
- Did he give you pricing? What type of approval did you give him?
- Did you check his contractor license?
These are a few questions I can think of quickly. I can come up with more if I know more. The point is depending on what was done and when, you could have a strong case or a weak case. If you have a descent case, then you can file a complaint with your counties consumer protection board. If might already know about this guy. If they agree with your case, then they will help mediate the issue. If it does not get resolved then, they will take him to court.
The good thing is that you are in your house.
Feel free to respond here or PM to discuss further.
Good luck,
