Get matched with top boiler installation pros in Fairhaven, MA

"The installers came out on time at 8:30 am and completed the installation later that evening. Explained everything, labeled all the pipes, and were careful to put everything back in place and clean up before they left. Overall very professional and polite. Would definitely recommend this company."

"I recently asked Nick to remove an old cast iron boiler from my basement, and I couldn’t be more impressed with his service. From start to finish, he was professional, efficient, and extremely knowledgeable. The job wasn’t easy, cast iron boilers are bulky and difficult to maneuver—but they handled everything with great care and precision. They showed up on time, worked diligently, and made sure to keep the area clean throughout the process. The crew also took the time to explain what they were doing and answered all my questions clearly. What really stood out was their attention to detail and respect for my home. They protected my floors, cleaned up thoroughly afterward, and ensured everything was in great shape before leaving. I highly recommend Nicholas Gouveia Plumbing and Heating to anyone looking for reliable, skilled plumbing services. I’ll definitely be using them again for any future work!"

"Excellent response time, installation and knowledge base!"

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

"The sales team and installers were professional and responsive. I had contacted other companies for quotes. Peter and team came right away and were considerate of my home and health. The others were not. When looking at my home they gave me the options needed for our unusual configuration and home history. They wore PPE and were meticulous . So happy to have a climate controlled home!!! If that is what you want call Majic!"
