“In June 2025 I contracted with Bob Gagnon Plumbing & Heating Lowell, MA to install a new high efficiency boiler and water heater. I am impressed with the level of craftsmanship and high quality of the materials. Bob did the work himself, soldering all the pipes and connections. He also partners with a trusted electrician (Tessier Electric), and they coordinated the work so there were no delays or downtime for either of them.

I highly recommend Bob Gagnon for quality repairs or replacement systems. He will keep you informed at every step and lets you know what to expect as he goes. This job exceeded my expectations.“

He was punctual, professional, and took the time to explain the work clearly before getting started. The job was completed efficiently, with great attention to detail, and everything is working perfectly. It gave us real peace of mind knowing the propane system was handled by someone so knowledgeable.

We highly recommend David to anyone in need of plumbing work—reliable, skilled, and a pleasure to work with!“
