Charlie was highly recommended by my renovator, Rob to install the Thermann instantaneous hot water system and change all the gas piping. Firstly, he fixed the plumbing pipe that was broken in my bathroom while renovating. Not long after that, my hot water system broke down. He sent his staff, Chase who did a very good job, very professional, friendly and knowledgeable. They worked from early morning till evening making sure all the hot water is working. Job well done. Thanks to Charlie, Chase and his team.
