Hello, My husband and I recieved a notice of intent to lien from the plumber who subcontracted on our new home. The amount is roughly $3,300. There is no mortgage on the house. We paid him $19,000 already. This is a disputed balance since the final bill was 50% higher than he bid ($15,500). In addition, he did not bill regularly throughout the project and was in fact the last subcontractor to submit a bill. Our general contractor disputed the bill with him and requested details about the $3,300 in extra labor and we have invited them both to sit down to discuss, but the plumber hasn't responded. He specifically told my husband (who requested that he discuss with it with our contractor, "I'm not going to beg for my money." His crew also did some shoddy work that had to be redone by another subcontractor. We are more than willing to pay justifiable overages, but he appears unwilling to provide detail. What are our options as property owners?
