What I really liked about my recent experience with the guys over at Preferred Plumbing & Drain was that they were very informational. These guys were really good at explaining what they were doing, what caused the problem, and how to prevent the problem from returning. They came right on time which I loved because promptness is very important to me. They did great work and my problem has not come back thanks to their work as well as the advice they gave me. Will definitely use these guys again, they are great!
