Water Heater Repair & Replacement in Madison, AL
No hot water, rusty water, popping noises, or a puddle under the tank: these are the calls Madison plumbers get most. Many Madison homes are still on their original water heaters, and most tank units last about 8–15 years, so replacement season arrives for whole neighborhoods at once.
Repair or Replace?
Repair usually makes sense when the heater is under about 8 years old and the problem is a part: a thermostat, heating element, thermocouple, gas valve, or pilot assembly.
Replacement usually makes sense when the tank itself is leaking, the unit is past 10 years old, the water is rusty, or repair costs approach half the price of a new heater.
Warning Signs
- Water pooling around the base of the tank
- Rusty or discolored hot water
- Rumbling or popping (sediment buildup)
- Hot water running out faster than it used to
- Pilot light that will not stay lit (gas units)
- Tripping breaker (electric units)
Tank vs. Tankless
Tank heaters cost less upfront and are simple to replace like-for-like. Tankless heaters cost more to install but deliver endless hot water, take up less space, and often last 20 years. Read the full comparison: tank vs. tankless water heaters.
Water Heater Cost in Madison
- Repair (part replacement): typically $100–$600

Inside Madison city limits, water heater replacement requires a permit from the City of Madison Building Department. Expansion tanks, drain pans, and code updates may add to the price; ask for an itemized quote.
Make Your Water Heater Last

- Test the temperature and pressure (T&P) relief valve annually
- Check the anode rod every few years
- Keep the thermostat around 120°F
Common Questions
Why is my water heater leaking?
A leak from a fitting or the relief valve can often be repaired. A leak from the tank body means the tank has corroded through and needs replacement. Shut off the water supply and power or gas to the heater until it is checked.
How long does replacement take?
A like-for-like tank swap usually takes 2–4 hours. Tankless conversions can take a full day.
