The short version

A water heater company you can actually trust

A failing water heater has a way of picking the worst possible morning to quit. When it does, you don’t want a sales pitch or a mystery bill. You want a licensed local plumber who shows up, tells you straight whether it needs a repair or a replacement, and gives you one clear price before touching anything.

That is exactly how CleanTap works. Sean, Luiz, and the team have replaced water heaters in hundreds of Massachusetts homes, from tight attic closets in older Boston-area houses to spacious utility rooms in newer South Shore builds. We stock the most common tank and tankless units, so most replacements happen the same day you call. And because we are a water company first, we test your water while we are there at no cost, so you know exactly what is feeding your brand-new heater.

What we install

Every type of water heater, one accountable team

🔥

Gas & electric tanks

The dependable standard. Fast recovery, straightforward install, and the lowest upfront cost. We carry 40 and 50-gallon units for same-day swaps.

Tankless (gas & electric)

Endless hot water and a smaller footprint. Great for busy households and anyone tired of running out mid-shower. See tankless options.

🌿

Heat-pump / hybrid

The most efficient choice, with the lowest running cost and Mass Save rebate eligibility. A smart pick if you want to cut energy bills long term.

🔧

Repairs

Not every problem needs a new tank. We fix thermostats, elements, thermocouples, valves, and pilot issues when a repair is the honest call.

💧

Expansion tanks & code work

Many older MA homes need an expansion tank, updated venting, or a new shutoff to meet current code. We handle it and pull the permit.

🏠

Whole-home upgrades

Replacing the heater and rethinking your hot water setup? We size it right for your household instead of overselling capacity you won’t use.

What it costs

Repair or replace?

Signs it’s time for a new water heater

A standard tank lasts about 8 to 12 years, and a tankless unit can go 20 or more with maintenance. If yours is getting up there and showing any of these signs, it is worth planning a replacement before it fails on its own schedule instead of yours:

Rusty or discolored hot water

Rust inside the tank means corrosion. Once it starts, it only goes one way.

Rumbling or popping noises

Sediment has built up on the bottom, making the unit work harder and fail sooner.

Water pooling at the base

A leaking tank is the one that can’t wait. Call us before it floods the space.

Not enough hot water

Running out faster than you used to often means the tank is failing or undersized.

Age past ten years

Near the end of its life, a big repair rarely pays off versus a new, efficient unit.

Rising energy bills

An aging heater loses efficiency. A modern unit can quietly lower your monthly cost.

Our rule of thumb is simple. If a repair costs more than half the price of a new unit and the tank is already near the end of its life, replacing it saves you money and a second service call. When we come out, we tell you plainly which side of that line you are on. Sometimes the honest answer is a small fix, and we will say so.

How it works

From your call to hot water, same day

1

Tell us what’s happening

Call or send a quick note. We ask a few questions and, on most replacements, get you scheduled the same day.

2

Fixed price up front

We confirm the right unit and size for your home and give you one clear price. You approve it before any work begins.

3

Clean, code install

Our licensed plumber removes the old unit, installs the new one to code, hauls the old one away, and leaves the space clean.

4

Free water test

Before we go, we test your water at no cost, so you know what’s feeding your new heater.

Local knowledge

Water heaters in Massachusetts homes

Massachusetts homes come with their own quirks, and a water heater install is where they show up. Older homes around Boston, the South Shore, and the SouthCoast often have tight mechanical closets, aging shutoffs, and venting that predates current code. Newer construction is more forgiving, but sizing still matters when a household runs several showers, a dishwasher, and laundry in the same morning.

State law requires a licensed plumber and a permit for a water heater replacement, and that protects you. It means the work is inspected, the venting and expansion tank are correct, and the install won’t come back to bite you when you sell the home. We handle the permit, the code details, and the cleanup as part of the job, not as surprise add-ons. It is the difference between a heater that was swapped and one that was installed properly.

Questions

Water heater installation FAQs

How much does water heater installation cost in Massachusetts?

Most installed replacements run about $650 to $1,150 for an electric tank, $700 to $1,250 for a gas tank, $1,300 to $2,500 for a gas tankless, and $1,600 to $2,700 for a heat-pump unit. A permit adds $50 to $150, and older homes sometimes need code work. Our cost guide breaks it all down, and we give you a fixed price before we start.

Can you replace my water heater the same day?

Usually, yes. We stock the most common tank and tankless units and can often complete a replacement the same day you call. Tankless conversions that need new venting or a gas-line change may take a little longer, and we will tell you exactly what to expect.

Do I need a permit to replace a water heater in MA?

Yes. Massachusetts requires a licensed plumber and a permit for a water heater replacement, typically $50 to $150. If a company offers to skip it to save money, that is a red flag and it can cause problems when you sell your home. We always pull the permit.

Should I switch to a tankless water heater?

It depends on your home and how you use hot water. Tankless units cost more up front but last longer, save space, and never run out. For a large or busy household, the extra cost often pays off. For a smaller home on a budget, a quality tank is still a smart buy. We will give you an honest recommendation, not a sales pitch.

Is a heat-pump water heater worth it?

If low running cost matters to you, yes. Heat-pump (hybrid) units have the highest sticker price but the lowest operating cost, and they qualify for Mass Save rebates that standard units do not. We will walk you through the current rebate math before you decide.

How long does the installation take?

A straightforward tank swap usually takes 2 to 4 hours. A tankless install runs 4 to 8 hours because of the venting and gas work involved. We give you a clear timeline with your quote.

What size water heater do I need?

It comes down to your household size and hot-water habits. A 40-gallon tank suits many smaller homes, while larger families or multi-bathroom homes do better with a 50 to 75-gallon tank or a high-output tankless. We size it to your actual usage so you are not paying for capacity you will never use.

Do you offer financing?

Yes. We offer $0-down financing with simple monthly payments, which is a popular choice when a heater fails unexpectedly. Ask us and we will lay out the options with no pressure.

What areas do you serve?

We install water heaters across Greater Boston, the South Shore, and much of Eastern Massachusetts, from our Braintree and Mansfield bases. If you are nearby, there is a good chance we can be out the same day.

Do you remove the old water heater?

Always. Removing and responsibly disposing of your old unit, and cleaning up the space, is part of the job, never a surprise add-on.
