Most no-hot-water calls in New Jersey are fixed for $495 to $900 — a thermocouple, an igniter, a tripped breaker, a failed thermostat or a reset switch. Call (201) 676-3099 or book a free estimate.
Most no-hot-water calls in New Jersey are fixed for $495 to $900 — a thermocouple, an igniter, a tripped breaker, a failed thermostat or a reset switch. A leaking tank is different: that one gets replaced, and a 40 to 50 gallon gas heater installed here runs $2,200 to $3,200 in 2026. Before you call anybody, run the six checks below. Two of them cost nothing and fix the problem about a third of the time.
Is it leaking? Do this right now
There is a valve on the cold water pipe entering the top of the tank — usually a lever or a round handle. Turn it off. If it is seized or you cannot find it, shut the main water valve where the water line enters the house, normally on the front basement wall near the meter.
On a gas heater, turn the dial on the gas control valve to OFF, and if the leak is bad, close the gas shutoff on the pipe feeding the heater — the handle sits across the pipe when it is closed. On an electric heater, shut the double breaker at the panel. Never leave an electric element powered in a tank that is draining.
Fifty gallons goes a long way across a basement floor. Get boxes, rugs and anything electrical up off the ground, put towels at the edges, and photograph everything before you clean up. Then call — a real person answers 24/7, and in Bergen, Passaic, Hudson, Essex and Morris we are often there within the hour.
No hot water? Do these 6 things first
Electric heaters run on a 30 amp double-pole breaker. If it is tripped, reset it once. If it trips again, stop — that is a failed element or a short. Almost every heater in New Jersey also has a light-switch-looking service switch near it, and people bump those doing laundry more often than you would believe.
Pop the upper access panel and look for a small red button on the thermostat. That is the high-limit reset, called the ECO. Press it once. If it trips again in a day, the thermostat or the element is failing and the heater is telling you so.
Modern gas heaters have a small LED near the gas valve that blinks a fault code, and the legend is printed on the label right there on the tank. No blink at all usually means a dead thermopile or no power to the control. Photograph the label and the blinking light and text it to us — that alone often tells us the part to bring.
Older heaters have a standing pilot. Follow the printed steps exactly, wait the full purge time, and if it will not hold after the second try, stop. A pilot that lights and dies is a thermocouple or thermopile — a $495 to $700 fix, not something to keep fighting. If you smell gas at any point, leave the house and call the gas emergency number on your bill.
Someone may have turned the dial down, or a new thermostatic mixing valve on top of the tank may have drifted. Set the tank to about 120 degrees — hot enough to be useful, cool enough not to scald a kid. If only one fixture has no hot water, the problem is that fixture's cartridge or shutoff, not the heater.
Gas heaters in a closed closet need combustion air. A blocked vent, a bird nest in the chimney or a new door that sealed the closet will trip the safety switch. Soot around the draft hood or a scorched label means combustion is spilling into the room — stop and call us.
What do the noises mean?
- Rumbling or popping when it fires — sediment on the tank bottom. Flush it, or if it is over eight years old, plan the replacement.
- A hiss or sizzle — water dripping onto the burner. That means the tank is leaking from above. Shut it down.
- Water running when nobody is using any — a stuck relief valve or a failed mixing valve dumping hot water into the drain.
Repair or replace? The age math
Find the age on the label: the first four digits of the serial number are usually the month and year it was built. If it says 2013, you are on borrowed time. A replacement also needs a plumbing permit under the New Jersey Uniform Construction Code, and we pull it.
| Age of the tank | What we do |
|---|---|
| Under 6 years, part failure (thermocouple, igniter, element, thermostat, gas valve) | Repair — $495 to $900 |
| 6 to 9 years, part failure | Repair if it is a cheap part; replace if it is the gas valve or a second failure |
| 10 years or older, any failure | Replace — $2.2K to $3.2K for a 40–50 gal gas tank installed |
| Any age, leaking from the tank body | Replace. A rusted-through tank cannot be repaired |
| Any age, leaking from a fitting or the relief valve | Repair — often under $700 |
What does it cost to have somebody come out?
Our minimum visit is $495 and it covers up to two hours of a licensed plumber plus common parts on the truck — not a trip fee on top of the repair. After hours, weekends and holidays, the emergency minimum is $695 for the same two hours. No surcharge appears on the invoice later.
Across the rest of New Jersey, expect a $75 to $200 service call fee, $100 to $250 an hour, and $300 to $650 for the first hour after hours. Always ask whether the diagnostic fee comes off the repair price.
When is it a real emergency?
- Water is actively running out of the tank or the fittings — shut it down and call now
- You smell gas anywhere near the heater — leave the house first, then call the gas emergency number on your PSE&G, New Jersey Natural Gas or Elizabethtown Gas bill, then call us
- Soot, scorching, or a carbon monoxide alarm going off — get everyone out and call 911
- The relief valve is discharging hot water or steam — that is a pressure or temperature fault, not a drip
- No hot water in a house with an infant, an elderly parent or anyone who needs it medically — call, we will get there today
Where these numbers come from
Repair and replacement ranges come from 2026 price pages published by New Jersey plumbing companies, national cost guides including HomeGuide, Angi and Fixr, and our own 2026 quotes and invoices across North Jersey. The diagnostic and after-hours figures are the published New Jersey market, not national averages. Our own minimums are set by us: $495 for a standard visit, $695 for an emergency, both covering up to two hours.
Questions people ask next
Why do I only get lukewarm water?
On a gas tank it is usually a failing dip tube, sediment stealing capacity, or the thermostat set too low. On an electric tank it is almost always a dead lower element — the upper one still heats the top, so you get a few lukewarm minutes and then cold. That is a repair, not a replacement.
The pilot keeps going out. Can I just keep relighting it?
You can, and it will keep going out. A pilot that will not hold means the thermocouple or thermopile is no longer keeping the safety valve open, or the pilot orifice is dirty. It is an inexpensive fix, and ignoring it means a cold shower on the coldest morning of the year.
How long can a leaking water heater wait?
A drip from a fitting can wait hours. A tank weeping rust-colored water is failing and can let go all at once. Shut the water to it, shut the gas or breaker, and call the same day. In a finished basement that is the difference between a $2,800 replacement and a $10,000 event.
Do you charge more at night or on the weekend?
The emergency minimum is $695 and it covers up to two hours, nights, weekends and holidays included. You approve the number before we start. There is no separate after-hours fee that appears on the bill later.
Should I flush my water heater every year?
Yes, especially where the water is hard. Twenty minutes of draining sediment off the tank bottom buys years of life. If your tank has never been flushed and it is over eight years old, leave it alone and plan the replacement — flushing an old tank sometimes finds the hole.
