We often receive calls from homeowners who are surprised to learn of mechanic's liens placed on their homes by people or businesses the homeowner has never heard of. These liens usually are asserted by those who have supplied the contractor with goods or services incorporated into the work. One of our clients was shocked to learn a lumber supplier was asserting a lien and threatening to foreclose on her home. She had paid the contractor (more than the contractor had a right to collect) but the contractor failed to pay the supplier. We sued the contractor and within two months collected a refund sufficient to resolve the mechanic's liens and recoup fees and costs of litigation. Incidentally, before signing any home improvement contract, it is good idea to obtain legal advice. It is much more cost effective to consult with a lawyer at the beginning of a construction project than the end.
