About GEM


Our mission is to delight homeowners with trusted expertise and next-level service


A family company serving millions of neighbors

GEM Plumbing and Heating was founded on the principles of family, community, and courtesy. Larry Sr. and Gloria Gemma started up the business in 1949 with those values in mind, and brothers Larry, Lenny, and Eddy Gemma continue to lead the company with the same principles, delivering a range of services to homeowners, commercial clients, and mechanical projects throughout Rhode Island and into Massachusetts and Connecticut. 

With over 350 employees, 165 trucks (and counting), and three regional offices, GEM has grown into one of the largest service companies in the United States today. Our 70 years of experience in the plumbing, electrical, and heating and cooling trades helps us deliver superior service no matter the issue, and our reach allows us to be there when you need us most!


Areas we Serve

Different regions have different regulations, restrictions, and requirements when it comes to installations, repairs, and maintenance. That’s why the GEM experts at each of our local offices have a deep understanding of local code and the level of service your home needs. 

We have three offices that serve dozens of cities and counties in southern New England. Check out our locations below for more information on our service areas and our offerings.

An Eye on Innovation

Our goal is to stay true to our roots while we work to improve our service. We’ve joined with HomeX to offer Remote Assist service: Connect to an expert tech over the phone, and they’ll help diagnose and even solve your issue right then and there (no need to open your front door). Curious how it works? Learn more about Remote Assist. 

We also offer tailored memberships to help you save time and money on routine maintenance and repairs, installations, and upgrades. Our aim is to make it as easy as possible for you to take care of your home — find the Home Advocate membership that suits you.
