Get matched with top tankless water heater installers in Waterbury, CT

"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"We decided not to go tankless but E&R did a great job installing a new 50 gal Rheem heater. Very quick and clean install. I will use them again in the future."

"Very knowledgeable plumber. Willing to do beyond what is needed to accomplish task ( removal of water softening system) Very fair pricing."

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"The installation of the new boiler was excellent! They were quick and cleaned up everything when they were done. We were so impressed with their workmanship that we had them install â mini splitsâ for cooling. Extremely satisfied and happy with their work. I would highly recommend them."

"Mike was excellent. He came in was very polite and professional. He quickly provided the quote and in less than an hour had removed the old leaky faucet and installed the new one. It worked perfectly and looks amazing in the kitchen. Mike removed all the old parts and new faucet packaging. He even gave me pointers on diy checking water pressure to make sure there is not too much pressure coming in. Also, reminded me to register my Delta faucet which I did shortly after. Thank you Mike!! Price seemed a bit high, but it was done right away on a Saturday! With 6 month warranty on the plumbing work."

"Total Mechanical Systems went the extra mile. In one week they fixed my water heater and the igniter on my furnace. They were prompt and did exactly what they said. Their service techs are knowledgeable, and when the tech who came to my house couldn't diagnose the problem, he called in a more seasoned tech. They both worked on it for some time but only charged me the $99 diagnostic fee. Well done!"
