Cal from Master plumbing did great work at our house! He was here for a multiple-day job, worked very hard, and was very courteous and professional. We had an old cast iron drain backed up, cracked and leaking that needed to be replaced. All of the old plumbing was removed along with much jackhammering and digging to remove the old drain pipe. A new drain was installed quickly, which was a relief, as it allowed us to use our kitchen sink and dishwasher again! New rebar was installed and new cement was poured. The work is high quality and should function for many years to come. Master plumbing worked efficiently with our insurance company and was pretty good about staying in communication with us. Cal is a very skilled and experienced plumber, and was great at answering our questions. He went above and beyond by minding our gates to keep our dogs from getting out, and made sure to clean up after all the work. We are very happy with Cal and Master Plumbing and Leak Detection!
