Family owned and operated since 1939, we are the first registered plumbers (License #1) in the First State. We are a customer centric plumber, with 70+ years experience. Certified in the latest "green solution" in on-demand water heaters , our expertise is in older homes, focusing on updating or repairing custom work done by craftsmen. 1st Class Service! Timely, Appropriate, Reasonable Price. I have had my many things done by Dauphin's (Furnace replaced, water heater replaced, and various other plumbing repair). I would recommend A.J. Dauphin & Son to anyone that might need a plumber. A.J. Dauphin had been recommended to us when we needed plumbing services. That was nine years ago. We were delighted with the quality of work performed and we have continued to rely on them ever since. Customer service, particularly responsiveness, is critical to us. Whenever we have a problem, we know we will have it dealt with promptly and effectively. They are respectful of the fact that modern life is busy and they work hard to accommodate us.

We recently had to go through an unexpected kitchen reno due to mold. With very little warning, the kitchen was down to studs and we discovered we needed our whole house replumbed. The first company I consulted quoted me about $1,300 more than AJ Dauphin & Son and the two techs that came out were kind of alarmist. Whereas Dauphin sent out Newt, who was calm and walked me through the situation and his plan to do the job. I went with Dauphin and I couldn't have been happier. Newt and John were fantastic - total professionals who clearly take pride in their work. Everything was meticulous and they left the work areas impeccable. Newt came back two separate times after the initial replumb - once to lengthen the lines through two base cabinets and again to hook up the sink/faucet/dishwasher/water filtration system. The second time, no charge. The third time, parts only. The company's owner, Dan, could not have been nicer and was always willing to talk things through with me on the phone. I will never use another plumber again, and I highly recommend these guys to anyone who believes in quality work at fair prices. Thank you to the full team for making this one part of the harrowing process a dream more than a nightmare.
