Responsive and committed… our needs are met and the work is professional. As good as it comes… note: I’m writing this in a cool, comfortable setting now. 😁
I am very pleased with ALex's service. He is knowledgeable and polite.
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!
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.


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.

We Install All Types of Water Heaters in Wellesley

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

Here’s a look at the types of water heaters we install in Wellesley:

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. For consistent hot water without surprises, a properly sized tank water heater gets the job done.

Tankless water heater installation in Wellesley appeals to homeowners who want endless hot water and energy savings. 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. GEM installs tankless water heaters in Wellesley homes looking for efficiency and long-term value.

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.
