The contractors that did work on my home did extremely bad work. About halfway into the work they were doing (completely tearing down and redoing my back porch) I realized they had not obtained any permits from the city. When I asked them about it, they told me they didn't need permits - which is untrue. After they realized I demanded permits for them to continue, they left, never came back and never responded to any of my calls, emails or letters. Shortly after, they put a lien on my home. But now, they are no longer in business. Can the lien be removed?
