Hello. A company is threatening to file a mechanics lien against my home. They were contracted through our home insurance provider. The home insurance representative has sent the company an email disputing their work, double charges on some items, and inaccurate measurements/charges. The company is not responding to the home insurance and is insisting that I pay the amount dictated or they will file the lien. Can they do this even though there are apparent errors/fraudulent charges in the bill they are asking me to pay?
