What our customer’s are saying about Dunphy Plumbing & Heating

Bill did an outstanding job

“I called Bill because I was looking to replace a vanity and toilet in my new condo. This is my first renovation experience as I am a first time home owner. Bill did an outstanding job; he arrived on time, was friendly and personable, worked quickly and efficiently, and his work spoke for itself. I am extremely happy with how it all turned out. I have since reached out to Bill again to help us with a shower renovation as well. Thanks Bill!”

Kendra - Hyannis, MA

He’s One Of The Best.

I’ve used many contractors having added a huge addition to my home, and would rate Bill as one of the best I’ve worked with. He replaced a tankless water heater that was at the end of its life with a unit he recommended, got us hot water within a day, and completed the project within two days, with everything cleaned and inspected. His professionalism, knowledge and expertise are explicit and his work ethic is beyond reproach. I would and will recommend Bill in a heartbeat. Based on my experience, he’s one of the best.

Scott from Franklin

Bill did a quality job at a competitive price

“Owner Bill Dunphy is very responsive and professional, and really takes pride in his work. We had two Navien high-efficiency condensing units (gas heating and tankless hot water) installed by Dunphy Plumbing and Heating for our 2-family in Boston about 6 months ago, in the time and price quoted. Bill did a quality job at a competitive price, and stands behind his work, promptly answering my phone calls (even on Sundays). Top quality service and professionalism makes Bill from Dunphy Plumbing and Heating, the only plumber I will ever call.”


“They did a very thorough job at a reasonable price.”

This Team Rocks

Using Google, I called this company and received a call back within 15 minutes – shocking. A polite young man assisted me in troubeshooting the problem with my washer. Guess what? It worked. My washer now has a load of clothes – I had been going to the laundromat for a couple weeks. The technician said, “Miss, I’d rather try and help you over the phone before coming out and charging you.” As Oprah would say, we love a company who is honest and knows their craft.  Thank you, thank you, thank you.

Shirley from Stoughton


After having multiple issues with my heating system and calling numerous companies, Bill from Dunphy Plumbing and Heating came right out and fixed the problem. Very friendly, affordable, and reliable. Would definitely use him again and recommend him to friends.‎


A Smart Choice

Bill replaced my 40 gallon HW heater and suggested the implementation of auto shut-off valve technology to prevent any mishaps in my finished basement. His pricing was very competitive and I was able to get multiple items accomplished in what another plumber quoted me for just a HW tank installation. He came recommended and I certainly would recommend him to others, as he does fantastic work and is very responsive.


Very happy with Bill

Coil went on water heater. Made numerous phone calls, Bill was quick to answer and quote price. Extremely competitive. Job very well done – within the day. Worked clean, answered all questions. Will use Bill again, and have referred him to friends and co-workers.


A plumber who does things right the first…

Bill was on time, gave great advice, chose the right products, and gave a fair estimate. Work was done on time and to the estimate. Courteous, fair, timely, easy to talk to. Replaced bath and kitchen pipes and fixtures. When work was done, everything was neat and clean. Thanks Bill ! I will call again! Dunphy Plumbing and Heating…


Dun-RIGHT and price right

I called Bill at Dunphy Plumbing and Heating to install a hot water tank.  He showed up on time and did a great job.  His price beat Home Depot and Lowes. I will use Dunphy Plumbing and Heating again.

A plumber with INTEGRITY

Hi, my name is Sharon, and I called Dunphy Plumbing and Heating. Bill Dunphy Owner showed up on time and was friendly and courteous. My plumbing problem was a backed-up bathroom sink. Bill snaked the drain and made my problem go away, and my kids were no longer fighting over one sink in the morning. Thanks Bill.
