Get matched with top boiler installation pros in Fairhaven, MA

"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!"

"Jordan did a great job installing a hot water heater in my condo. I was able to him photos of the existing setup and the worn out boiler. So that helped to speed up the process. The following day Jordan was back with a helper and they were finished in a little over two hours. And the best thing....Jordan pricing was very fair."
