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

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"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."

"Had oil heat system replaced to tankless, after converting to gas. Job was done perfectly, finally have unlimited hot water supply, and we have since used blue bear for other small plumbing jobs as they come up."
