“Alberto and Giovanni were excellent. They installed a new water tank system and serviced our boiler. The team was professional, thorough and communicated throughout the process. They also were mindful of moving large tanks through our house and left the area spotless. We highly recommend Flow Master Plumbing. Especially Alberto and Giovanni.”

“Hats off to Connor for his conscientious work during our recent heating project. He was with us every step of the way being available, responsive, and particularly sensitive to our needs. We also want to compliment his perseverance and creativity when faced with surprises and challenges. We would highly recommend the entire Flowmaster team who worked on our behalf to anyone considering a heating or plumbing project in the future.”
- Richard C.
“They show up when they say they’re going to show up. I sent out a job for bid and Flow Masters Plumbing came in with well-qualified bid, not just on price but also in terms of professionalism. They are on time and on budget, and the crew is well trained in their specialties.”
Barbara S.
“Up to date with the latest technology in radiant heating, fire, and domestic plumbing. Sometimes I need all three of those, in one project. Other plumbing companies have sent staff whose qualifications I doubted. Not Flow Masters. All the people they send seem well qualified. And, they’re responsive. Always get back to me by EOD.”
“Highly recommend! We needed a full replacement of all kitchen cold water lines and drains for our 12-unit condominium building. Flow Masters did such a great job we hired them again for our personal kitchen remodel and multiple jobs at a rental property.”
“They helped make my home eco-friendly! My home, built in 2002, wasn’t a smart home. Flow Masters helped us make it energy efficient by installing radiant heating. And, they did everything that has to do with water — tubs, showers, sink, faucets.”
