24/7 Emergency Plumbers in New England

Very professional and the work was done in time.

Excellent , professional and quick service! 👍

Chris disconnected plumbing for the kitchen sink. He was fast and friendly.

Doug was respectful, thorough and determined to fix a complex problem we had in our 10-year old furnace and duct system. It took some significant investigating, a couple of trips out here, but he did it! Much appreciated! He has also taken our overall heating/cooling and reviewed, cleaned out and educated us on maintenance items.

Eric and Steven are great! So professional and very nice guys! Love them! I will always request them for everything we need or want done here! Love them! Thank you guys 💙

I called for an estimate and service and got an appointment promptly. Jacob came in and looked at the work needed and gave an estimate on site and was back within 1 week to do the job. Jacob was very courteous and he explained what was needed, in a manner that I could understand. He was very professional. I am very pleased with his work. I will definitely call upon Gem in the future if I need services. Thank you Jacob. Job well done.

Excellent service! The guys who installed were awesome. Very happy customer!

Review for David Salvatore from Gem Plumbing and Heating

I recently had the pleasure of working with David Salvatore from Gem Plumbing and Heating on March 31, 2026, when he performed maintenance on my air conditioning systems. The service he provided was exceptional and very thorough. David demonstrated great professionalism, expertise, and efficiency throughout the process.

My overall experience with David was great, and I would highly recommend his services to anyone in need of HVAC maintenance and repairs. Thank you, David, for your excellent work!

Main water shut off valve needed to be replaced
GEM was fast efficient and extremely courteous
I highly recommend them

Nathan Campbell did a great job !

Great experience. On time, pleasant and performed work efficiently.

Nicole was incredibly knowledgeable, honest, and efficient! I was so thankful that she was able to get here quickly on a Saturday when we had an unknown alarm blaring in our basement. It turned out to be something in our AC unit that was luckily replaceable same day.

I joined the membership. I'm disabled and the membership will help with any future issues.

Very professional and communicative. Really appreciated David's work.

Professional, courteous, knowledgeable to answer all my questions. The work was done in a neat and timely manner

Brody and his associate were outstanding from start to finish. They came in kind, knowledgeable, and got the job done quickly! Exactly what you want! GEM is the real deal. Highly recommend!

Aaron came for a 2nd successful visit. This time to figure out the cause of low/no water pressure in some of our H&C setups for 5 bathroom sinks. He left with 3 sinks H&C flowing freely & demonstrated the need for 2 new faucet installations so Hot H2O could be restored to the remaining sinks. Much appreciated as others had immediately started talking about replacing pipes without investigating less complicated solutions. As before, Aaron was a professional pleasure to have in our home & pricing will be the only holdup for us to continue with the faucet installations. Due to him, I have high hopes for the GEM electrician arriving next week & the HVAC maintenance later this month.

Joseph H did a great job for us . After hours
He fixed our boiler so quick he was polite & very efficient . Thankful for him

The folks at Carmine's always do a great job👍 Tim is a great plumber, explains things, and provides options.

Very professional service. They came the same day and solved the problem quickly and completely. I would definitely use Gem again if I needed plumbing work.

I called GEM because I wanted my ductless AC’s checked to see if they needed any service. Christopher Cennamo came and examined both units and said they were functioning properly but needed a cleaning to remove mold and dirt. The large unit is at the top of a stairwell so access requires a tall ladder. Christopher made the appointment to return to do the cleaning and also to determine why the larger unit was tilting off the wall. He returned today and determined that the larger unit’s mounting bracket was only attached to drywall and not a wooden stud. He and Brody Lott secured the mounting bracket to a stud, ensuring the unit is now securely on the wall. A thorough cleaning of both units was completed including removal of a mouse nest. Christopher told me how to use steel wool in the outside pipe cover to prevent mice from entering which I promptly did. Christopher Cennamo was very professional, thorough, knowledgeable and explained everything. The cleaning was expensive but worth it. Plus he didn’t charge extra to repair the faulty mounting issue because GEM had done the initial install and not done it properly. I highly recommend Christopher Cennamo for any of your heating and cooling jobs.
