I wanted my driveway expanded. I hired contractor a. He came out the first week of may, laid the forms and rebard. As may went on the concrete was never laid, I kept getting execuses why. By june 15 my money was refunded in full. I ended up going with another contractor to complete the job. Earlier this week contractor a shows up to my house with concrete, without a word to me, and is angry because the job is done. He calls me and says that I owe him for the forms and rebarb...even though he has refunded my money, and if we cant come to an agreement he is placing a lien on my house. Can he do this? And what happens if he does? Will i be notified legally if he does?
