Our pipes froze the morning of christmas eve. Mark was the only plumber who called me back and walked me through the issue. We are in a new house, and unfamiliar with frozen pipes! Mark was ill, but stayed in touch over the holiday with a plan to come out Monday morning. His advice seemed to work and the water flowed again Chrismas night. For someone to respond over the holiday, while under the weather, speaks volumes. Mark will be my "go to" plumber as long as I live in Philadelphia - -great guy, very knowledgable! 10 STARS.
