I signed a contract for 1,300. With a brick contractor to tuck point 4 sides of brick rails on the front of my home. He covered the 100 year old face brick with excessive mortar destroying the face of my home. I stopped payment on his check. I have no confidence he can correct this without causing more damage, and prefer to secure another contractor. He threatened a lien on my home. What recourse do I have? To fix this job will require acid wash and more cost to me. Please advise.
