Repair or Replace? We'll Give You the Straight Answer
Water heaters typically last 10-15 years for traditional tanks and 20+ years for tankless. If the tank itself is leaking (not just a valve or supply line) and it's over 10 years old, it's time to replace. Rusted-through tanks can't be patched. But most failures are repairable: a failed heating element on an electric unit, a thermocouple on a gas unit, a clogged burner assembly. We diagnose first, then lay out repair vs. replacement costs honestly so you can make the right call for your home.

Water Heater Repair FAQ
No hot water. What should I check first?
Gas units: check the pilot light (follow the relight instructions on the label) and verify the gas valve is on. Electric units: check the breaker hasn't tripped and the high-limit reset button isn't in. If that doesn't work, call us.
My water heater is leaking. How urgent?
Very urgent if leaking from the tank body. The tank will eventually rupture. Leaks from the T&P valve, drain valve, or supply lines can often be repaired without urgency. Either way, shut off the water supply and fuel/power to the unit and call us.
How much does water heater repair cost?
Element or thermostat replacement on an electric unit: typically $300-500. Thermocouple or gas control valve on a gas unit: $250-500. Tankless descaling service: $300-400. We quote before starting.
How long should a water heater last?
Tank-style water heaters: 10-15 years with typical water conditions. Tankless: 20+ years with annual descaling. Heat pump water heaters: 12-15 years. Regular maintenance extends lifespan significantly.
