Nate came out first thing in the morning to help with my clogged sewer main. He was very professional and kind. He explained everything with no difficulty and offered multiple cost-tiered options. Mainly whether we would utilize a camera in the process of snaking the main. I appreciated being offered the option. We went with the camera process. So we could fully diagnose the issue, and determine if this would be a recurring problem.
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 PVCโ€”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.
Nateโ€™s customer service skills were out of this world. I advise GEM Plumbing to invest in this young man.

Incredible company.
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.

I was able to schedule an appointment for the next day. The technician was great. Chris went over everything that needed to be done and explained it clearly. Very professional. He was also able to offer a discount and waived the fee for the service call. When I reviewed the bill that night, there was an error and the fee hadnโ€™t been waived. When I called Gem the next day, they saw the error and immediately corrected it. Said the refund would be put on my credit card. Very happy with the service.

I am very happy with my well water pump service. David Chapman and his associate were professional, friendly and respectful. David showed me how to change my filter for which I am truly grateful.
It was super easy booking online The next day the dispatcher, (unfortunately I donโ€™t know her name) called to offer an earlier appointment. She was very polite and kind.
My whole transaction was smooth and pleasant from start to finish!


How to Know When You Need a New Water Heater Installed

Your water heater is telling you something.

Our plumbers help East Dennis homeowners recognize when their water heater is failing. Look for these indicators.

Water heaters typically last 8 to 12 years before needing replacement. If yours is at the older end of this range or beyond it, the system is likely losing efficiency and could fail at any time. Replacing it now helps you avoid unexpected breakdowns.

Water pooling near your water heater means the tank is corroding from inside. Once leaking starts, it cannot be fixed. New water heater installation in East Dennis should happen quickly to prevent damage to your home.

When your water heater takes longer to heat water or never reaches the temperature you set, internal components are failing. Sediment and worn parts reduce heating capacity. Replacement restores proper performance.

Loud sounds from your water heater indicate sediment has hardened at the tank bottom. This buildup reduces efficiency and stresses the system. If flushing doesn’t eliminate the noise, water heater replacement in East Dennis is the next step.

We Install All Types of Water Heaters in East Dennis

Choosing the right water heater means matching capacity to your household’s needs. GEM guides you to the best solution.

Tank water heater installation in East Dennis 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 East Dennis 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 East Dennis homes looking for efficiency and long-term value.

Water Heater Installation FAQs

Can GEM handle water heater emergencies in East Dennis?

Yes. We provide 24/7 emergency service throughout East Dennis and the Cape Cod area. If your water heater fails unexpectedly, leaks, or poses a safety concern, call us immediately. Our technicians can respond quickly to assess the situation and get your hot water restored as soon as possible.

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 East Dennis 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.

Will you haul away my existing water heater?

Absolutely. Removal and disposal are standard parts of our service for East Dennis customers. We disconnect your old water heater, carefully remove it from your home to avoid damage to floors or walls, and take it for proper disposal. Your installation price includes everything from removal to cleanup.

When does it make more sense to replace my water heater instead of repairing it?

Three situations typically point toward replacement: age over 10 years, a leaking tank, or repair costs exceeding half the price of new equipment. In East Dennis’s historic sea captains homes and beach cottages, we often see water heaters that have been patched multiple times but keep developing new problems. At that point, you’re throwing money at a system that’s fundamentally failing. GEM can help you weigh the costs and make the decision that’s right for your situation.

Do I need a permit for water heater installation?

In most cases, yes. Water heater installation typically requires a permit to ensure the work meets local codes. GEM handles permitting as part of our standard service for East Dennis customers. We pull the necessary permits and schedule inspections so you don’t have to navigate that process yourself.
