A contract for upgrade of impact windows signed on April 2018. The Contractor didn't finished the job within the contractual agreement; now have passed already 1 year and six months and the windows where finaly installed but the permit from the city of Aventura was partialy approved because the exterior caulking and adjust frame need to be corrected. The contractor is refusing to do that job and he said that he is going to put a lien in the porperty. As a consumer what are my rights?
