A Burbank plumbing company stated I needed a new sewer line based on video findings of line. He contracted another company to do the work since lost permitting rights for city work. The sub discovered my line could not be replaced using closed ditch due to concrete over line. Original plumber told him to do just saddle and did not consult with me until this was done. Now they want payment and I never got a new sewer line. Can't use the new saddle for open ditch line. If I had been called I would not have approved the saddle work but put my money towards a new line via open ditch. Am I responsible for subcontractors cost? Can he file a lien on my property?
