"I had a tankless water heater installed. I gave 4-1/2 stars for overall rating because the worker who came was the lone installer and had no one to help. I could not use water for almost sever hours an inconvenience since job was estimated to be "about 4 hours". I think he took a deserved lunch break for about an hour. He was on time and was courteous and pleasant. Would have been nice if he had a helper."

"Excellent work, very professional. Logan made sure everything was in perfect working order and cleaned up very well after he was completed. 12/10 will hire again if need anything down the road. He installed and replimbed my hot water heater, whole home filtration system, water softener, and multiple fixtures throughout my home!"

"My old hot water heater died, and a friend installed a new small 40 gal tank. But I never had hot water after that. I also had a leaking lead pipe. Patrick came and had to be a sleuth to try to determine the cause of the missing hot water. The tank was too small and not functioning, but the real problem was a crossed pipe somewhere in my 1890 house. He found the pipe location in the basement and put in a shut off valve, which gave most of the house hot water. He also put in a high quality 50 gallon tank, and repaired the leaking lead main. To completely fix the hot water, it will mean opening walls, so we left a small 1/2 bath sink and attic sink to be fixed at a later time (or not....).. This was all around Easter, but he put in long days to get it all done."

"I could not ask for a better experience from a plumbing contractor. The technician, Tony, was prompt, courteous, extremely quick in assessing the problem and getting my old water heater replaced. Valerie, who was the phone representative that took my initial call, was so helpful and kind to me. Not to mention, their pricing was very reasonable and more than competitive in our market. I will certainly be using Young Plumbing again for my home and I am going to spread the word to my neighbors and friends if they need a great plumber. Just a very satisfying experience on every aspect of their service."

"I contacted them and they were able to schedule an appointment for the removal of the old tank heater and install the new tankless heater the next day. They contacted me with an arrival time, Dean was very professional and kept me up to date on the progress. He was very professional and did a nice job on the project, we are very happy with the new tankless heater."
