GEM Home and Commercial Services

About the company

Founded in 1949 by Larry Sr. and Gloria Gemma, Gem Plumbing & Heating is a family owned business that is run today by Larry, Lenny and Eddy Gemma. Gem has been in business for nearly 70 years and we are dedicated to upholding the quality and timely service that our company was founded upon.

Today, Gem Plumbing & Heating has over 300 hard working employees, with over 165 trucks, making it one of the largest plumbing, heating and cooling companies in the United States. Our size allows us to be there when you need us the most! Despite our size, we are still committed to serving the local community with excellent service, as well as with the good works of the Gloria Gemma Breast Cancer Resource Foundation, established in 2004 in loving memory of Gloria Gemma.

In 2008, the Foundation opened its Resource and Wellness Center, and Gloria’s eldest daughter, Maria Gemma-Corcelli, was named the Executive Director. Through the tireless efforts of Maria and her dedicated staff, the Foundation has developed and implemented numerous programs and services for people living with breast cancer. Gem is also a proud supporter of McAuley Ministries, local technical schools and colleges and many other worthwhile organizations in our community.
