Whether it's a sudden leak or a planned upgrade to tankless, we've got you covered with an accurate diagnosis, clean, code-minded installs, and friendly, on-time service.
Hot water is one of those things nobody notices until it's gone. When yours disappears, our local technicians get there fast, find the failed part, and fix it right the first time.
Not every water heater can be saved, and not every home has the right one. These are the two ways we put a better heater in place.
Installing a water heater is part plumbing, part gas or electrical work, and part code compliance. Our technicians handle all three, so the heater runs safely and efficiently from day one. Every install starts with a site visit and a clear quote, with no surprise add-ons.
Tank water heaters typically last 8 to 12 years. When the tank itself starts leaking or the hot water turns rusty, no repair will save it, and the right move is a new heater sized to your household. The price is settled before the old tank is drained, and the new one goes in with the permits and code items your jurisdiction requires.
For most Newton homeowners, a water heater repair usually comes in somewhere between $150 and $600. Small parts like thermocouples, elements, and drain valves sit at the low end, while a gas control valve costs more. Newton Water Heater diagnoses the problem first and gives you a clear price before any work starts.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Heating element or thermostat (electric)No hot water, or a short and lukewarm supply | $150–$350 | Most common electric repair, usually same visit |
| Thermocouple or flame sensor (gas)Pilot lights but will not stay lit | $150–$300 | Pilot lights but will not stay lit |
| Gas control valveLargest common repair; compare to replacement past 10 years | $300–$700 | Valve will not open or regulate; weigh it against replacement on older tanks |
| Anode rod replacementRotten-egg odor or a rod worn down to bare wire | $150–$350 | Extends tank life when caught early |
| T&P relief valveWorn valve replaced with the correct rating | $150–$300 | Worn valve replaced with the correct rating |
| Dip tube replacementCracked tube mixing cold water into the hot supply | $150–$300 | Hot water runs out fast, plastic bits in aerators |
| Drain valve replacementDrip at the bottom valve, often plastic on older tanks | $100–$250 | Leaking or stuck valve at the base of the tank |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.

Call (617) 209-6516Water heater trouble shows up in many ways. If you're seeing any of these problems, don't wait to call for prompt help.
No hot water usually traces to a pilot that won't stay lit, a worn thermocouple, or a burned-out element, all fixable, and all diagnosable in one visit.
Same-day repair detailsWater on the floor can come from a loose fitting, a weeping drain valve, or a relief valve doing its job. Each one means something different, and we sort out which you have.
Water heater leak repairRusty hot water can mean the anode rod is spent and the tank is starting to corrode. Catching it early can add years to the heater.
Maintenance & flushingWe size replacements by household demand and first-hour rating, not a guess, so the new heater keeps up with your busiest mornings from day one.
Water heater replacementAn error code on a tankless unit is the heater telling you what it doesn't like, often scale buildup, an ignition fault, or a flow sensor problem.
Tankless repairWe size and install tankless units carefully, with the right gas line, venting, and a descaling setup, so they deliver steady hot water for years.
Go tanklessExperience is what separates a lasting fix from a temporary one. Our technicians know how these heaters fail (combustion, controls, sediment, corrosion) and match the repair to the actual cause.
A water heater never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
We treat your budget like our own: fix what's fixable, replace what isn't, and size every new heater to your household instead of the biggest tank on the truck.
We don't just swap the failed part. We check what killed it (high water pressure, sediment, a bad vent draft, a loose wire) and correct that too, so the same failure doesn't come back.
Water heaters are our specialty, not a side job. Because we work on them every day, we've learned how local water, local construction, and local codes affect the way they age, and we bring that knowledge to every visit, from a simple element swap to a full replacement.
Knowing the area is half the job. We've learned which neighborhoods have hard water, which older homes need their venting brought up to code, and what inspectors here look for on permits, and we put that knowledge to work so each job is done right the first time.
One call connects you with a nearby technician who can size up the problem and get you a quote.
Our 4-step process is designed for accuracy, speed, and zero surprises on the invoice.
Call (617) 209-6516 and we'll get you a price quote, often within a day. A few quick questions (gas or electric, tank or tankless, what it's doing, how old it is) and we'll book a time that works for you.
We don't guess. The diagnostic covers the full system, including the supply lines and venting, and turns into a plain recommendation with the cost spelled out up front.
Whether it's a quick thermocouple swap or a full tank changeout, the work is done carefully, tested thoroughly, and left cleaner than we found it.
The job isn't done until hot water is flowing and verified at a safe temperature. We'll also show you the simple habits, and offer the maintenance schedule, that add years to the heater's life.
Same-day appointments · Honest, upfront quotes
There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime, like closing the water valve above the tank.
Our experienced technician arrives at your property with diagnostic tools and the common replacement parts ready to get started right away. Thermocouples, elements, thermostats, and valves are already on board.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the heater is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for heaters in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"When our electric tank died we decided to try a heat pump water heater. They walked us through the space and airflow it needs, pointed us toward the utility rebate information, and installed it in a day. We noticed the savings on the very first bill."
"We run a small restaurant and lost hot water in the middle of the lunch rush. Their team got someone out that afternoon and had our commercial unit running again before dinner service. They understood what downtime costs a Newton business, and they came back to service our second unit the following week."
"Our tankless unit kept flashing an error code and shutting off mid-shower. They descaled the heat exchanger, cleaned the inlet filter, and replaced a failing flow sensor. It has run perfectly since, and now we know to have it descaled regularly."
Your household runs on hot water every single day. Here's why local families choose Newton Water Heater.
We don't wait for failures to profit from them. Every maintenance visit is built around your heater's age and condition. For hard-working heaters, a new anode rod at the right time can add years to the tank. Simple as that.
Real experience is a requirement, not a bonus. It means every technician reads combustion and electrical faults correctly, works clean and safe, and explains the work in plain language at a level most companies don't reach.
Effective doesn't have to mean oversold. We size heaters honestly and install them to code with quality fittings and clean workmanship, so you get reliable hot water with minimal disruption to your household.
