How much does water heater replacement cost in North Metro Atlanta? Water heater replacement from JMJ Plumbing typically runs $2,200 to $2,600, including the unit, code-compliant installation and haul-away of the old heater. These are our own completed-job ranges across North Metro Atlanta, not national averages. Your final price depends on the specifics of the job, and we confirm it with you before any work begins.
JMJ Plumbing provides professional water heater repair and replacement services to restore reliable hot water to your home. No hot water, rusty water, leaks, or popping and rumbling sounds are often signs that a water heater needs immediate attention—whether that means a critical repair or full replacement. We diagnose problems quickly, perform repairs when they make financial sense, and replace failing units with properly sized systems designed to meet your household’s needs. Every installation includes the correct code-compliant connections, along with attention to expansion tanks, shutoff valves, and other essential safety components. The result is dependable hot water, improved efficiency, and peace of mind that the job was done right.
Signs Your Water Heater Needs Repair or Replacement
Most water heaters give warning before they fail completely. Call a licensed plumber if you notice any of the following:
- No hot water or not enough hot water — often a failed heating element, thermostat, or pilot/igniter problem.
- Rusty or discolored hot water — usually a sign the anode rod is spent and the tank is corroding from the inside.
- Popping, rumbling, or banging sounds — sediment has hardened on the bottom of the tank, which reduces efficiency and stresses the steel.
- Water pooling around the base — a leaking tank cannot be repaired and needs replacement.
- Age past 10–12 years — a standard tank water heater typically lasts 8–12 years.
- A sharp rise in your gas or power bill with no change in usage.
Repair or Replace? How We Decide
We recommend repair when the tank itself is sound and the failure is in a serviceable part — a thermostat, heating element, thermocouple, gas control valve, or T&P relief valve. We recommend replacement when the tank is leaking, when the unit is near or past its expected lifespan, or when the cost of the repair approaches a meaningful share of a new, more efficient unit. We will always tell you which situation you are in before any work begins.
What Our Water Heater Service Includes
- Diagnosis. We test the unit, check the gas or electrical supply, inspect the venting, and identify the actual point of failure.
- Options. You get a clear explanation of repair versus replacement, including correct sizing for your household if replacement makes sense.
- Correct sizing. Tank capacity and first-hour rating are matched to the number of bathrooms and people in the home, not just swapped like for like.
- Code-compliant installation. Proper connections, expansion tank, shutoff valve, drain pan, T&P discharge piping, and venting to current Georgia code.
- Haul-away. We remove and dispose of the old unit.

Water Heater FAQs
How long does a water heater last?
A standard tank water heater typically lasts 8–12 years. A tankless unit typically lasts 15–20 years. Annual flushing extends the life of both, and water hardness in your area is the single biggest factor in how quickly sediment builds up.
How long does it take to replace a water heater?
A straightforward like-for-like tank replacement is usually a same-day job taking a few hours. Converting from tank to tankless takes longer because it often requires new gas line sizing, new venting, and electrical work.
Why is my water heater making a popping or rumbling noise?
That sound is water boiling underneath a layer of hardened sediment on the bottom of the tank. It means the unit is working harder than it should and losing efficiency. A flush can help early on; if the sediment has hardened, replacement is usually the better value.
Can you replace a water heater the same day?
In most cases yes, for standard tank replacements. JMJ Plumbing offers 24/7 emergency service, so a failed or leaking water heater does not have to wait for business hours.
Do I need an expansion tank?
If your home has a pressure-reducing valve or a backflow preventer, it is a closed system and Georgia code requires thermal expansion control. We check for this on every installation rather than assuming.
Is a leaking water heater an emergency?
Yes. A leaking tank will not repair itself and can fail suddenly, releasing 40–80 gallons of water into your home. Shut off the water supply and the gas or breaker to the unit, and call us right away.
Do you service both gas and electric water heaters?
Yes. Our Master Plumbers service and install gas, electric, and tankless water heaters for both residential and commercial properties.
