Water heater repair costs $150–$600 depending on the component. Thermostat replacement runs $150–$300. Heating element replacement is $200–$400. Pressure relief valve replacement costs $100–$200. If repair cost exceeds 50% of replacement value on a unit over 8 years old, replacement is usually more cost-effective.

Why is my water heater not producing hot water?

No hot water is most commonly caused by a failed heating element (electric) or a faulty thermocouple or pilot light (gas). Both are repairable. A licensed plumber can diagnose and fix either issue in a single visit.

How long does water heater repair take?

Most water heater repairs take 1–2 hours. Heating element replacement on an electric unit takes about 90 minutes. Gas component repairs typically take 1–2 hours including safety testing.

Is a leaking water heater worth repairing?

A leak from a fitting or pressure relief valve is usually repairable. A leak from the tank itself means the tank has corroded internally — replacement is the only option at that point.
