Should You Repair or Replace Your Water Heater?
Not every water heater problem means you need a new unit — many issues are simple, affordable repairs. But a few signs usually mean replacement is the smarter long-term choice: the tank itself is leaking or rusted through (not just a loose fitting), the unit is 10+ years old, you've had repeat breakdowns, or repair costs are creeping close to the price of a new one. If you're not sure which situation you're in, we'll take a look and give you a straight answer — no pressure either way.
My Water Heater Is Leaking — What Should I Do?
A leaking water heater is one of the few plumbing problems worth acting on right away. Water pooling at the base can mean a loose drain valve or fitting (often a simple, low-cost fix), or it can mean the tank itself has corroded and is failing internally — in which case repair isn't an option and replacement is the only permanent fix. Either way, don't wait: even a small leak can damage flooring, drywall, and nearby belongings the longer it runs. If you can safely reach the cold water supply valve on top of the unit, turning it off will stop water from continuing to feed the tank while you wait for help.
Puddles or moisture around the base of the tank
Rust-colored water or visible corrosion on the tank
A hissing, dripping, or "weeping" sound from the tank
Water around the base only when the tank is heating (often a pressure relief valve issue)
The tank is 10+ years old and has started leaking for the first time
No Hot Water? Here's What's Usually Going On
If your water heater isn't keeping up, the cause usually falls into one of a few categories. On a gas unit, a pilot light that won't stay lit or a failing thermocouple/igniter is a common culprit. On an electric unit, a burned-out heating element is the most frequent cause of lukewarm or cold water. Sediment buildup at the bottom of the tank can also insulate the water from the heat source, especially in an older unit that's never been flushed — this often shows up as hot water that runs out much faster than it used to. And if the unit is simply undersized for your household's demand, running multiple showers or appliances back-to-back can outpace what it can recover. Most of these are straightforward repairs; we'll diagnose the actual cause before recommending anything.
Emergency Water Heater Shutdown & Safety
If you're dealing with a water heater emergency, here's what you can safely do while you wait for help — and when to call in a professional instead.
Shut off the cold water supply valve on top of the water heater (turn clockwise) to stop feeding a leaking tank
If safely accessible, switch off the breaker for an electric water heater, or turn the gas control valve to "off" for a gas unit
Call a plumber for a leaking, corroded, or malfunctioning water heater once the water and power/gas are shut off
Call your local water utility if the main shutoff valve itself has failed or you can't stop an active leak at the source
If you smell gas, leave the area immediately and call the gas company or 911 from outside — do not attempt to locate the leak yourself
Need a New Water Heater? Here's What to Expect
Sometimes replacement really is the right call — and when it is, we make the process straightforward. We repair all major brands, but when it's time for a new water heater, we recommend and install Bradford White units for their reliability and strong warranty support. We'll walk you through your options (including tank vs. tankless if that's a fit for your home), give you a clear, upfront price before any work begins, and handle the full installation — old unit removed, new one installed and tested, done right the first time.
How Much Does Water Heater Replacement Cost?
Every home and every water heater is different, so we don't quote a one-size-fits-all price over the phone. What you pay depends on a few key factors: the size and type of unit you need (a standard 40-50 gallon tank vs. a larger tank vs. tankless), whether it's gas or electric, whether any code-required upgrades are needed (venting, straps, expansion tank, etc.), and how accessible the installation location is. We provide a free, honest estimate before any work begins — you'll know the exact price and what's included before you decide anything.
Tank vs. Tankless: Which Is Right for Your Home?
Both options do the same basic job — keep hot water flowing — but they get there differently, and each has real trade-offs worth understanding before you decide:
Tank water heaters cost less upfront and are quicker and simpler to install
Tankless units heat water on demand, so they never run out — a real plus for larger households
Tankless units are more energy-efficient long-term but cost more upfront to purchase and install
Tank units are simple to service; tankless units need periodic descaling, especially with hard water
If your home's gas line, venting, or electrical setup supports tankless, it can be a great upgrade — we'll tell you honestly if it's a fit for your house
Water Heater Maintenance & Lifespan
A little maintenance goes a long way toward avoiding an unexpected breakdown — or an unexpected replacement. Most water heaters last 8-12 years, and a few simple habits can help you get the most out of yours:
Flush the tank once a year to clear out sediment buildup and help it run efficiently
Test the pressure relief valve periodically to make sure it isn't stuck or leaking
Check the anode rod every couple of years — a worn-out rod lets the tank itself start corroding
Keep the area around the unit clear so it has proper airflow and is easy to access
Once your unit hits the 10-year mark, keep an eye out for the early warning signs above — catching a failing unit early gives you options instead of an emergency

Can a leaking water heater be repaired?
Sometimes. It depends on where the leak is coming from. A leak at a fitting, connection, or valve can often be repaired. A leak from the tank body itself usually means the tank has failed internally and needs to be replaced. A technician can identify the source and give you an honest recommendation.
Does a leaking water heater always need replacement?
No. Not every leak means the tank has failed — leaks from the T&P relief valve, drain valve, or plumbing connections can often be fixed without replacing the unit. We'll always confirm the cause before recommending replacement.
How long do residential water heaters last?
Most tank water heaters last 8-12 years with normal use and maintenance, though this varies with water quality, usage, and how well the unit has been maintained. Sediment buildup and lack of anode rod maintenance tend to shorten a tank's lifespan.
How much does water heater replacement cost?
Cost depends on the size and type of unit, whether it's gas or electric, the installation location, and whether any code upgrades (venting, gas piping, electrical, expansion tank, drain pan) are needed. We provide a free estimate and confirm the price before any work begins — no surprises.
Is no hot water usually repairable?
In many cases, yes. Common causes — a bad thermocouple or pilot issue on gas units, a failed heating element on electric units, sediment buildup, or an undersized unit for household demand — are often repairable without a full replacement.
Should I repair or replace an old water heater?
It depends on the unit's age, the type of problem, and its repair history. An older unit with a tank leak, frequent breakdowns, or heavy corrosion is usually a better candidate for replacement, while a single, isolated issue on a newer unit is often worth repairing. We'll walk you through the tradeoffs in person.
How quickly can a water heater be replaced?
Once we've evaluated your unit and confirmed pricing, most standard tank replacements can be completed in a single visit. More involved jobs — like a tankless conversion or one that needs code upgrades — may take longer. We'll give you a clear timeline before starting.
What size water heater do I need?
The right size depends on your household's hot water demand — the number of bathrooms, appliances, and people in the home. A technician can evaluate your household's usage and recommend an appropriately sized tank or tankless unit.
Tank or tankless — which is right for me?
It depends on your household's hot-water demand, available space, budget, and how your home is set up for gas or electric service. Tank units typically cost less upfront and are simpler to install; tankless units take up less space and supply hot water on demand. We can walk you through which fits your home.
Can I replace a 40-gallon heater with a 50-gallon heater?
Often, yes, as long as the installation space, venting, and gas or electrical supply can accommodate the larger unit. We'll evaluate your specific setup during the estimate to confirm what will fit and what, if anything, needs to be upgraded.
What causes a water heater to leak?
Leaks can come from several places: the tank body itself (usually corrosion or internal failure), the top water connections, the drain valve, the T&P relief valve, or nearby plumbing connections. Where the leak is coming from determines whether it can be repaired or the unit needs to be replaced.
Is a leaking water heater an emergency?
It depends on how much water is leaking and how quickly. A slow drip is usually not an emergency but should be looked at soon. Active flooding or a leak you can't stop at the unit's shutoff valve is more urgent — shut off the water supply if it's safe to do so and call us right away.
How do I know if my water heater tank has failed?
Signs include water pooling at the base of the tank, rust-colored water, popping or rumbling noises from sediment buildup, and a tank that's approaching or past its typical 8-12 year lifespan. A technician can confirm whether the tank itself has failed.
Is it worth repairing an older water heater?
Sometimes. A minor, isolated issue can be worth repairing even on an older unit. But if the tank itself is leaking, heavily corroded, or has needed repeat repairs, replacement is usually the more practical long-term option. We'll give you an honest assessment either way.
What should I do in a water heater emergency?
If it's safe to do so, shut off the cold water supply valve at the top of the unit and switch off the breaker (electric) or gas shutoff valve (gas) if accessible. If you smell gas, leave the area immediately and call the gas company or 911 from outside. If an active leak can't be stopped at the unit, call your local water utility to shut off water at the meter. Otherwise, give us a call and we'll get a technician out to you.
