Electrical Upgrades in Rhode Island and Massachusetts

Fast, efficient, neat, timely. Couldn't ask for more!

The two gentlemen William and Mark did a professional job unplugging my kitchen sink and the pipes all the way to the septic system. They showed great respect for property. They worked deliberately to get to the problem. They cleaned up and closed up so you couldn’t even tell they were here!!

Great service!

Chris did a fantastic job. It works great thank you so much.

Excellent response, with a comprehensive explanation of repair options Area was left spotless

The men who put this together were working very hard. They got this done in terrific two days. Great work guys!!!

Caio worked tirelessly. He has excellent teaching skills as well as skills re AC installment. He very patiently and expertly reviewed for my full understanding the functioning of the wall monitor.

Very polite and efficient

Great crew. Explained all details of work. Kept all work areas clean. Professional and courteous. Would highly recommend. A+++++

Had a Kohler kitchen and Bathroom faucet installed with a vanity. Eric and Gem Plumbing did a fantastic job and kept us updated as they went along. Extremely knowledgeable, knew what they were doing, and gave us some information before they left. They explained their warranty and said “we’re around 24/7 if you need us”. I am not a plumber but train others in customer service. And Gem Plumbing gets an A++

Great tutorial and help. Fixed what I needed.

Both technicians were knowledgeable, professional, and extremely neat.

Colin was excellent. Very professional and thorough. Identified the problem, easy fix.

GEM showed up on time and worked cleanly.

Edgar was prompt, efficient and did a wonderful job.was pleasant and knowledgeable

As has consistently been the case with Gem, the service man was professional, the work was done right, and everything was clear and above board. But also, as always, it was not cheap. Still, it was an emergency and Gem was the only outfit to actually answer their phone (as opposed to leaving a message or filling out an online form that might be responded to the next day) and schedule an appointment quickly and appropriate to fixing the emergency.

Expansion tank removed and upgraded with new gauge and hardware

Joe is always a 5 star guy thank you mike thiel

Colin was quick, knowledgeable & thorough!

Brandon and Max showed up the day after I called for a cracked pipe/ stuck well water filter. They were super knowledgeable and explained the issues in easy to understand detail. Very responsive, fairly priced

5/5 Stars — Outstanding Service from GEM! I recently had GEM install a new radiator, and I couldn't be happier with the entire experience. From the moment they arrived, the technician , Roselio, was professional, knowledgeable, and extremely respectful of my home. The installation was done efficiently and with incredible attention to detail. They took the time to answer all my questions, made sure everything was running perfectly before they left, and left the work area spotless. It’s rare to find a company that combines such high-level craftsmanship with genuinely friendly customer service. If you need any heating or plumbing work done, I wholeheartedly recommend calling GEM. They truly delivered top-notch results!

A difficult challenge and yet the service was excellent, professional, knowledgeable and perceived to completion

Very good. Technician determined fluids were empty. Was able to fill with dye and rescheduled future appt to search for leaks Has already identified leak in condenser at pipe connection. Hopefully will resolve in future visit. System is operational at this time. Very professional and pleasant person. Thank you, A ———————- For Friday. Aug. 21, 2026 by John Excellent!!

Today we had our AC systems installed on the roof of our condo’s. The team from GEM were amazing. They were very professional, communicated every step of what they were doing which gave me great peace. The team, Omar who was the lead, John, Louis, Michael, Mike the electrician were phenomenal. Nick with the crane crew was very nice. I hope I didn’t miss anyone. It was so assuring watching them work so well together. Their respect for each other was present and refreshing. This job was done simultaneously between my neighbors condo and my condo which was huge. The team truly worked AMAZINGLY well together. Their checklist & cleanup was A PLUS PLUS. I would highly recommend GEM and their teams. Anthony Goris was very professional and expertly explained what was happening with my very old AC unit. He was very patient and kind with his time relieving my anxiety of a huge purchase. Edgar Pollino was also very professional and expertly explained my options. He was very knowledgeable explaining everything and very patient & kind answering all my questions. I would highly recommend GEM.

Professional informative knowledgeable and completely competent. Can’t thank you enough for a job diagnosing and fixing my HVAC system to 100%. Kudos to Arnold.
