"My 12-year-old water heater was on its way out, and it was finally time to replace it. Iâ ve always wanted to go tankless, so after many hours of research and finding reputable local plumbers in my area, I reached out to the Water Heater Company to analyze my current situation and come up with a replacement solution. Again, my goal was to go tankless; however, after Tanner from The Water Heather company surveyed my property and went over all my options, it was determined the configuration of my main gas line and proper placement of the unit would not be conducive to install a tankless unit as there were many obstacles, hours of labor, and resorting back to a tank heater would be the best option for me. Tanner suggested I go with a company called Bradford White, which has fantastic reviews and a unit that will give me some longevity. I decided to have Tanner install the unit, which included all-new copper fittings and much more. This company knows water heaters, and I appreciate his honesty that he could install a tankless heater, but financially, the layout of my house would not be in my best interest. Therefore, I felt comfortable working with The Water Heater Company to install my new Bradford White gas tank water heater. Tanner was highly professional, cleaned up after the job, and went through everything he did installing my new tank. I highly recommend anybody looking for a tankless or tank water heater contact the Water Heater Company, and if youâ re lucky enough, Tanner will be your technician."

"Excellent job! Good Guy Plumbing fixed my leaking water heater quickly and thoroughly for a fair price. Spoke with Robert over the phone and David came out to do the repair. Both were professional, knowledgeable and kind. I recently bought a new townhome and will be doing business with them for any future plumbing needs. Many thanks to David, Robert and Good Guy Plumbing. It’s such a relief knowing there are good, honest plumbers I can count on."

"I was very pleased with the super job they did for me. They got right out to my house, had the parts to fix my leaking hot water heater, and did so right away. I mentioned the hot water shutout valve didn't seem to shut off the water. They also had a better shutoff and installed it at my request. They were very friendly and polite. Before leaving they recomended a way to get the mildew that had started growing on my wall next to the water heater. "I AM A VERY HAPPY CUSTOMER" !"

"Stop looking for a plumber! Sam is the man for you job. I can’t say enough about him and his team. He worked within our budget, did top notch service, and even offered free advice for our other bathroom. Sam installed a tankless hot water heater, ran plumbing out to a brand new Adu, and helped us complete a perfect compact bathroom. Sam is a master of his craft and priced well. Thanks again Sam!!!"

"I set an appointment with Albano's Plumbing & Drain for Friday which made it easy for me and the guy was right on time, pulled the trap apart and fixed it. They were really good. They answered the phone and they were very professional, they told me when they could be there and when they couldn't, they gave me a choice of when they could come, the guy who came over was nice and clean and he did a really good job. I was very happy. He removed the sink, fixed it, put everything back, cleaned up and he was done."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Mike and his team were amazing. They quickly responded to my call about my leaking water heater on a Friday night, showed up 9am the next day, and had a new one up and running within two hours. He was upfront with the costs and even had us send him photos so he could give recommendations and transparent advice over the phone before we had confirmed we were moving forward with him. Mike also ensured that he secured the permits we needed from the city and provided consistent updates throughout the entire process. We've saved Mike's number as our go-to plumber and we'll be recommending him to anyone who needs similar services."

"I stared to look for a plumber after I found water under my water heater. I jumped on Angi and posted my issue. With in minutes....Art messaged me and said he can be her 1st thing in the morning. BTW. This was 10pm at night. His quick response was a plus for me. I had one other respond but he over extended himself to my need. He came at 7amd and said....you need a new water heater. I can got get one and install it now. I was a bit reluctant and he said call me when your ready and left. My wife said his prices looked fair and he seemed like a good plumber. I called him back and said lets dance. He was back at my home in a hour and 1/2...and started the work. He protected my carpet and placed plastic on it. He warned my that maybe the cost might go up due to the age of the pipes and valves. He had the old one out and the new one in an an hour or so. He was quick, clean and polite. I paid him and shuck his hand. I recommend Art for your household plumbing needs. He was excellent."
