Get matched with top tankless water heater installers in North Branford, 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."

"I received a call back promptly. Tom couldn t have been more helpful to me from walking me through shutting the water and the electricity to my water heater off. He gave me a fair deal on a new water heater made me the first appointment of the day because of having my son in the house and came promptly on time and finished the job very quickly. I really appreciate everything he did for my family and would recommend him to anyone."

"Great. They called to make appointment. Called to let me know they would be there in 15 minutes, Were on time, professional, efficient. Due to house and plumbing being 50+ years old, they did have to find a part at the supply store but came right back and finished the job. They advised us to get the lower shut off valve fixed in the future and sent us an estimate. Very pleased and would recommend them to my friends.$199"
