Our house was hit by a drunk driver. We hired a general contractor for the restoration but after the initial work we found their work to be shoddy. We paid them for the work they did and added the 20% profit and overhead that was allowed in the insurance settlement. They are now coming back to us saying that we owe them the profit and overhead for the work they didn't do. Is this legal? they have already sic'd their attorneys on us and are threatening court. What can we do?
