Get matched with top tankless water heater installers in Plympton, MA

"Jordan and his crew responded quickly and discussed various options. We decided to replace the old conventional water heater with a modern tankless system. I could not be more happy with the same day service, honesty, craftsmanship and professionalism of the team. Thanks for the reference."

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"Amazing experience all around. Easy to schedule and to work with, good deal and amazing work installing a tankless water heater. I will definitely call for any future needs."

"Outstanding. From the original estimate of services to be performed by Eric A to the install work, which was NOT an easy job, performed by Gil, Luis & Chris it was excellent job well done! Gil kept in contact with me throughout the job and provided his cell phone in case I had any other questions. As a small business owner I pay attention to details and know how important customer service is and this team from Cotti-Johnson were top notch. I cannot recommend them highly enough."

"Not only did Nick replace the hot water heater but also installed a whole house water filter system. Top notch installation very clean and professional. He will be our plumber from now on!"

"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."

"Showed up at promised time with all they needed to replace the water heater and completed the work in under an hour. Not my usual experience with plumbers. Price was the lowest of three I contacted."
