"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!"

"Patrick, the owner made the service call to my house in about 1/2 hour. I was alone, babysitting for my two grandchildren and very worried. I explained my problem, he told me what to look for (a water shut off valve) and asked if I could turn the water off. I told him I would try. I was frantic because with the babies, then not finding any shut off valve, water coming up from the floor, and clearing way for what I thought would be a wall tear down - Patrick and his "manager" (?) arrived. (Mind you, my family also came to help, but did not locate the shut off valve). The water pipe happened to run under my bedroom floor! Needless to say, WITHIN MINUTES the rushing water stopped. I still have water for daily household use as the problem was a broken pipe to the exterior spigot.  Patrick was soaked, yet took the time to explain to me why exactly this had happened. He encouraged me to wait until the Spring when the weather is warmer to make any changes and repairs. Patrick is professional, knowledgeable, and quite a gentleman, (despite being waterlogged) and I felt that he gave me all options for this future repair.

"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."

"These guys are great and were definitely the best value. Very knowledgeable and up on the latest technology and research in home comfort. We discussed some possible upgrades to improve efficiency and comfort and I was very confident in my decisions. Installers were professional and hard-working. The owner, Tim, is a really nice guy and I didn't feel rushed or pressured as we were talking through the options. Office staff was on the ball with gentle (not aggressive) follow ups. Also, TDH Mechanical guarantees the system for 12 YEARS parts AND labor!!! So if something, anything goes wrong with the system (other than you bashing it with a hammer or like your basement flooding) they come out and fix it at NO charge. That sealed the deal for me. It was refreshing to see somebody stand by the product and workmanship like that. I give them the highest marks."
