Gramman Plumbing & Heating

I have known for a long time that Gramman does excellent work. Now I want to add honesty to the review. I had a problem after hours with my shower. When I called, Joe talked me through how to fix it. I’m an older woman and if he had come over and fixed it-and charged me the emergency fees-I would never have known I could do it myself. Wow! What an honest company. Great work and honesty. You can’t beat that!

Tom was very professional & knowledgeable. If ever needed, we wouldn't hesitate to call Gramman Plumbing again. Overall, extremely satisfied with the work and we are very happy to have our hot water back!

Bobby and his entire team are dedicated professionals! As a first time home owners getting into oil to gas conversion was nerve wrecking. We met various teams but Gramman stood out extensively. They answered every questions and concerns we had and finished the whole project in an organized timely manner. We highly recommend them to everyone in need of quality work. Many thanks!

Great emergency response and attention to detail by Bobby and his dedicated team. Had the unfortunate experience of walking into a flooded basement over the weekend due to my old water heater which had outlived its life. I spoke to Dan on a Saturday night who walked me through what to do to stop the water from flooding through the hot water heater - He was fantastic. By Monday morning they were ready to replace my unit. Customer service, responsiveness and professionalism; 10 out of 10.

Gramman has helped us with several projects and smaller repairs over the years. This review is about the choice and installation of a "smart home" water leak detection and shutoff system. Gramman provided the information we needed to make an informed decision about choice of systems and installation. We decided on the Moen Flo, and then chose a setup with a bypass valve so that, in the event of a failure of the Flo system, we could bypass that equipment and continue getting water until the automated system was fixed. Gramman installed this somewhat involved setup flawlessly. Based on all of our experiences with these experts, we think Gramman is tops.

We have neen using Gramman plumbing for years. They are the most professional, most knowledgeable, polite and accomodating.Their service is neat and clean, and always prompt in keeping appointments

Gramman Plumbing is our "go to" for all of our plumbing needs. Today, Sébastien came to our house to change our bathroom faucet & replaced our p-trap. He did an outstanding job, clean, neat & efficient!

I did an oil to gas conversion after my oil boiler gave out. Grumman's plumber Rob and Nick were very punctual and clean and friendly. The installation of the new gas boiler and indirect water heater was very professional and neat and orderly. It took three day for them to complete the project and we are thrilled with the outcome. I would highly recommend them for any plumbing related work.

Called about a hot water issue yesterday (Monday), and all fixed by today midday (Tuesday). Tech was clean and professional, came on time, explained everything, and fixed it all. It is nice have a contractor you can trust!

Gramman Plumbing and Heating just completed an oil to gas conversion of our home heating system.
Our home is almost 100 years old, so this was not an easy operation.
Thanks to Joe and the entire Gramman staff, the project went smoothly and quickly.
I recommend Gramman Plumbing and Heating highly to any family that is considering any heating system upgrade or repair.

Gramman Plumbing has been a trusted name for decades . They are my go to plumbing company from emergencies to regular plumbing projects. I have hired them for all sorts of work, from replacing a leaking hot water tank in the middle of winter to legalizing old plumbing in the basement. Their knowledge about town codes and reputation sets them apart from others and they ensure to do things right the first time.

Overall, I truly like their workmanship and professionalism. I find them honest, punctual, and trustworthy, and a bit pricey but it is expected with that level of service. I know that they will get the work done right the first time and if there are any issues they will be there when I call them.

Bobby, JoAnna, Kevin and many more thank you so much for all your help and hard work on my recent project!

Gramman Plumbing is very responsive and professional. ... always pointing out your options before you commit to anything. Honest and reliable. We use them for our boiler service and any plumbing issues we have due to living in an old home. We also used them for our Oil to Gas coversion and they left our basement immaculate. Always giving you a very detailed written estimate so you can think things through. Great company with amazing friendly plumbers.

Jackie was amazing helping with staying in touch with my management office which was no easy task. But most of all the quality of service and repairs are best in class. Thank you so much Gramman.
