Get matched with top tankless water heater repair pros in Ansonia, 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."

"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."

"Mike and Todd worked quickly and installed a new water heater for a great rate. Was easy to communicate with during the entire process. Definitely recommend."

"Jason was first hired to come to repair a job that was not done properly by a prior plumber. We then needed him to re-vamp our bathroom tub/shower - new controls/tile work. Then another bathroom sink job. then a kitchen sink. We only trust Jason for our plumbing needs. He is licensed, and extremely knowledgeable."

"Kenny did an excellent job and I give him 5 stars. I was told by the office staff that the installation of the new water heater (under lifetime warranty but only five years old when it needed replacing) would take up to six hours. The actual work time was closer to two and a half hours, most of the time was taken up waiting for the delivery of the new heater as well as half-way through Kenny left for another two hours, maybe even longer, to pick up an expansion tank. I had been quoted a price of $950 for the installation . After the installation the office called to ask how I wanted to pay I challenged this amount and ended up paying $850 instead. - I very much appreciated that Quinns were able and did install the hot water heater so quickly but felt I was taken advantage of financially."

"He was very knowledgeable and gave me some advice on how to avoid future problems. He was also on time and the service was done fairly quickly. He took the time to make sure all repair needed was done correctly and assured me if any problems were to occur he would be back to fix."
