What Our Customers Are Saying
100% Satisfaction Guarantee
We found roots growing in an old, 2-foot, cast-iron section of my main drainage pipe.
He used a blade attachment and cleared the obstruction to the best of his ability. Then left me with a quote to have the 2-foot section of cast iron replaced with PVC—which is only a small section that penetrated the foundation of my home.
I was very happy with the service, and most importantly the transparent approach which allowed me to make informed decisions.
Nate’s customer service skills were out of this world. I advise GEM Plumbing to invest in this young man.
I had two whole house central AC units replaced (19 yrs old) and their team and other parts of the company (Plumbling, electrical, etc.) worked together to do an unbelieable installation in very hot conditions. My hats off to your company and we are so impressed that I contracted GEM to install a whole house 25kw generator.

Maintaining your home can be stressful. Let us help.
Preserve your home’s value, extend your equipment’s life span, and ease your worries with our membership plans.
Well-maintained systems run better, last longer, and save you money on energy bills. Regular care prevents breakdowns, extends equipment life, and keeps your home comfortable year-round. When it’s time to sell, buyers notice homes with documented maintenance history.
Cambridge properties do not fail on a schedule, and in a city where Victorian buildings house multiple families and century-old systems serve modern demands, after-hours problems require immediate expertise. That is why our technicians are on call day and night, responding to emergencies in Harvard Square, Cambridgeport, Inman Square, Porter Square, and every neighborhood in the city.
We understand what a boiler failure means when multiple units depend on one system, how to work around original woodwork and period details, and why an electrical issue in an older building requires someone who has seen it before. We know Cambridge’s housing stock, from the grand Victorians near the Common to the dense triple-deckers along Mass Ave.
Whether a winter storm stresses an aging steam system, summer humidity overwhelms an undersized cooling unit, or a plumbing emergency threatens a finished space, you have a team that understands the common issues in Cambridge homes. When something goes wrong, you’re not left waiting.
With us, you can spend less money to take better care of your home.
Membership plans pay for themselves. You get discounted rates on service, priority scheduling when problems happen, and regular maintenance that prevents expensive emergency repairs. Efficient systems cost less to run, and catching issues early saves you from major expenses down the road.
Keep all parts of your home operating at peak efficiency with regular maintenance tune-ups.
Your HVAC, plumbing, and electrical systems work together to keep your home running. Regular tune-ups ensure everything operates efficiently, safely, and reliably. We inspect, clean, and adjust systems before problems start, so you avoid breakdowns when you need your systems most.
