I am a flooring company that installed, sanded and coated a 3,000 sq ft house. New construction, first contract was for install, second was for sanding and finishing the wood. I was paid full for first and only half for second contract. Work is completed, and homeowners want more finished coats. They were told once they pay the rest of contract I will then buy more poly and do how ever many coats they want. Not putting any more of my own money into a job that I haven't been paid for. (When theres been many issues with money along the way. ) My question is, If I put a lien on the house/owners does that stop them from being able to move in until I am paid fully for completed contract? If not then what are my options this house isn't going to be sold probably past my days. Its just about finished built for Owners I am doing work for.
