The technician arrived. He came in and diagnosed the problem with my ductless system. He was able to get my system functioning, even though he didn’t have the pot needed to be replaced so temporarily we can run the system as it is he did he did his job by diagnosing the issue and doing a temporary fix?
I called GEM for a weekend, short notice pipe repair, and everyone was great from Hendry who I spoke to on the phone, to the two technicians Alec and Danny. They worked quickly, communicated clearly, and worked with me to come up with a solution I was happy with the price and result of. I would definitely call them in the future when things pop up.
Can’t say enough good things about Gem Plumbing and Thomas in particular. I easily got a came day appointment, Thomas the tech was here in the agreed upon window, provided 2 alternative estimates and once we selected, he completed the job right away – no need to make another appointment and come back another day. Great work, and even better service!
Chris A diagnosed my tankless water heater problem and repaired it quickly and efficiently. He answered all my questions with clear answers and was very helpful in alleviating any of my concerns. He gave excellent service!
Fast and knowledgeable service technicians.
William and Mark were excellent! They explained everything that they were doing and included us through the whole process. Would recommend them highly.
Very prompt and professional service!
The service provided by Mark and his partner was incredible. They took the time to explain all details of the situation and even helped make a call to a remediation company. They cleaned up after themselves and were very easy to discuss the repair process with.
Always a pleasure, professional expert service. Solving any problem simple or difficult!
Came even late at night to make sure we had working air conditioning
The team that installed the unit (Luis Herrera Mezquita Et al) was very professional and explained things thoroughly. I would highly recommend them.
Great customer service and understanding with us, and answered all our questions.
Knowledgeable technician attended to services thoroughly and had answers to all questions. Also helped with moving some furniture to ensure he could have enough working space. Very well done!
Fast service, clean work and AWESOME service guys!!!
My toilet stopped working this morning. I called Gem Plumbing at around 12:30pm and with an hour or so Nicole Tradd Technician was at my door. She did a fabulous job removing and replacing my toilet. She was very pleasant and friendly from start to finish! Great customer service all around!
Ricky from GEM was awesome. Second time he has taken care of something for us over the years !!!
Outstanding service!

. GEM came for heat pump ac semi annual maintenance
As always very pleased to have GEM for all of my plumbing and electrical needs!
Thank you GEM
Was very impressed with Gems
Tech who was able to repair our AC units during our first real heat wave.
Hope to do business with Gem at our new home soon
Thomas from GEM came out today for my annual air-conditioning service, and I couldn’t be more impressed. He performed a thorough inspection, topped off all the necessary fluids, checked and adjusted my filters, and made sure everything was running smoothly and efficiently.

What really went above and beyond was that he noticed a hornets’ nest growing next to my air-conditioning unit and took care of it for me on the spot. That was something I hadn’t even realized needed attention, and it saved me from a potentially unpleasant surprise later on!

Thomas was professional, knowledgeable, and incredibly helpful throughout the entire visit. It’s rare to find someone who pays such close attention to the details and takes such pride in their work. GEM is fortunate to have him on their team. Thank you, Thomas, for the outstanding service!
Technicians were highly qualified. Very knowledgeable and professional. Respectful towards me and my home. Completed installation with in timeframe and cleaned up the areas they worked in. My issue is with whoever issued the system’s equipment. After 6 hours of working the technicians discovered they had been given the wrong system until! Resulting in them having to return for another 6 hour work day! This resulted in an additional day of inconvenience for myself and my family. No one from the Gem administration/management team has contacted me to apologize or offer reconciliation. I am happy with the product and the performance of the technical staff. But not with the treatment from management.
We had a tree branch fall and take out all of our electric equipment. GEM answered immediately and got someone out quickly. Mike Alberto got the job done quickly and explained everything as he went along. Great job!
I would recommend Corey Mayo for his expertise and would love to take his service again when needed


How to Know When You Need a New Water Heater Installed

Watch for these signs that your water heater needs replacing.

Watch for these indicators in your Wellesley home. When they appear, GEM provides honest advice about your options.

Water heaters don’t last forever. Once yours reaches 10 to 12 years, components wear out and efficiency drops. Replacing before failure lets you plan the upgrade instead of reacting to an emergency.

Water or dampness around your water heater signals trouble. Even small leaks indicate tank corrosion that will only worsen. Catching this early and scheduling replacement prevents water damage to your home.

If your household used to have plenty of hot water but now runs out quickly, the tank is losing capacity. Sediment buildup and aging components reduce how much hot water your system can deliver. New water heater installation in Wellesley restores the supply you need.

An aging water heater works harder to heat the same amount of water, using more energy in the process. If your bills have increased without other explanation, your water heater may be the reason. A new, efficient system brings those costs down.

Your home’s hot water needs depend on your family size, daily routines, and available space. GEM helps you find the right fit.

Tank water heater installation in Wellesley is the tried-and-true choice for most households. These units store 40-80 gallons of heated water, ready whenever you need it. Tank models work with gas or electric power, install affordably, and deliver dependable performance for families running showers, laundry, and dishes throughout the day.

These compact units heat water on demand as it passes through, so you never run out mid-shower. Tankless systems mount on walls, freeing up floor space in tight basements or utility closets.

Water Heater Installation FAQs

What happens to my old water heater when you install the new one?

We take it with us. GEM handles complete removal and disposal as part of every water heater installation in Wellesley. Our technicians disconnect the old unit, drain any remaining water, remove it from your home, and ensure proper disposal. You don’t need to worry about getting rid of a heavy, bulky appliance yourself.

Does Mass Save offer incentives for water heater replacement?

They do, for qualifying high-efficiency models. The program offers rebates that can make upgrading to efficient equipment more affordable for Wellesley homeowners. GEM helps you navigate the options and choose equipment that qualifies for maximum savings. We’re familiar with the current programs and can guide you through the application process.

My water heater is having problems. Should I repair or replace it?

That depends on what’s wrong and how old the unit is. A relatively new water heater with a failed heating element or faulty thermostat is usually worth repairing. But if your system is approaching 10 years old and showing multiple symptoms like inconsistent temperatures, strange noises, and rust in the water, replacement is typically the smarter investment. GEM serves Wellesley with honest recommendations, not upsells. We’ll tell you what we’d do if it were our own home.

Can I get same-day water heater installation?

In most cases, yes. GEM maintains a large fleet of service trucks throughout the Greater Boston area, and we stock common water heater sizes so we can respond to emergencies quickly. If your water heater fails in the morning, we can often have a new one installed by afternoon. Call us and we’ll let you know what’s available for your Wellesley location that day.

What if my water heater fails on a weekend or holiday?

GEM offers emergency service 7 days a week. Water heater failures don’t wait for convenient times, and neither do we. If your Wellesley home loses hot water on a Saturday night or holiday morning, call us. We’ll respond to restore your comfort.
