A plumber did some work in a bathroom. The new marble counter was scratched when his worker installed a faucet. The plumber left a bill. I had told him about the scratches and I was in the process of finding someone reputable to fix the marred surface. He left a message on my phone telling me that if he was not paid by Friday that he would put a lien on my home. Can he do this or will he have to go to court? What else can happen?
