Mark has helped us yet again. This time he replaced our water heater. The process was seamless and extremely quick. Mark is extremely professional and easy to work with he leaves everything clean and will do whatever it takes to make sure you are happy! He has helped us with many plumbing fixes and continues to do great work I would recommend mark for any plumbing jobs you have!
Mark Canty is the best! Friendly, competent, communicative, creative, highly skilled, prompt - a consummate professional in every way! And C4 operates with a great customer-facing system.
Mark and his colleague were so friendly and helpful! They helped me get our water heater running again and gave advice on how I can check on it in the future. Thank you so much for the help and for doing it so quickly and compassionately!
Mark was incredibly professional and did great work. We needed a new water shutoff valve and fridge water line. I had received very high quotes from several other vendors. Mark was reasonably priced and was able to get it done quick. He even fixed our seized garbage disposal for free. I plan on recommending Mark and C4 plumbing to anyone in the area that is in need of work.
As a real estate broker, Mark never lets my clients down when work is needed. He always does things in a timely and professional manner, which I greatly appreciate. But I knew this would be the case when I recommended him because he did an Awesome job on my own house, taking out the polybutylene pipes and replacing with copper throughout.
