Hired a Restoration Company, has general B Contractor License in California. His contract has only $1.00 with no description of work or its cost. With tbd for completion dates. They also have done damage to our home, with improperly hanging of 11 doors, they painted latex over enamel with no prep or primer. Had a cslb expert out that determined their work does not meet Construction standards. This contractor put a lien on our home after I exited his $1.00 contract. What is our option in court with his lien? Does he have a vaild lien if he doesn't have a vaild contract?
