Under contract, my Contractor has failed to complete the job not only in a timely manner, but at all. He told me it would be completed by last Thanksgiving, 2021. Any correspondence results in a 2-3 week lapse in any further responses, always initiated by myself. Now my Homeowners Insurance is threatening to cancel for incomplete work. He has basically abandoned the project and the work that has been completed is shoddy at best. I was told by my insurance agent that I could put a lien on my contractors business. Is this correct and if so, where would I start?
