In Idaho a electrical contractor gave me a verbal bid of 2800. He tried to bill me for twice as much and still had not completed the job. Then I had to hire someone else to finish it because he was demanding I pay another 2000 before he finished and discovered he did it wrong ...he had electrical plan and there shouldn’t have been any ?’s. Have proof of emails before work etc. He held up progress of the job and lost me a lot of money overall. He never said there was going to be a change order in cost. Walls closed and painted and he then he was exposed that he did it wrong. Now he’s putting a lien on my house after I’ve already paid him 3/4 of the project fees in progress payments. I have to pay at least 2500 to get it done to code. What do I do?
