Know Whether the Water Heater Is Worth Repairing
Loss of hot water can come from an element, thermostat, ignition component, control, sensor, valve, or maintenance problem. Those issues may be repairable. A storage tank that has rusted through is not. We identify the source, consider the age and condition of the equipment, and explain the repair cost. If replacement is also reasonable, we compare the choices based on household demand and installation requirements rather than pushing one answer.

Water Heater Repair FAQ
No hot water. What should I check first?
Check the circuit breaker on an electric water heater. On a gas unit, check the status light or pilot according to the manufacturer's instructions. If you smell gas, leave the area and call the gas utility or 911. Do not remove electrical access panels. Call us if these basic checks do not restore hot water.
My water heater is leaking. How urgent?
A leak from the tank body needs prompt attention because the tank cannot be repaired once it has rusted through. A leak at a fitting, drain valve, or temperature and pressure relief valve may be repairable, but it should still be inspected promptly. Shut off the water and energy source if it is safe to do so, then 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 provide the repair price before work begins.
How long should a water heater last?
A traditional tank water heater often lasts about 10 to 15 years. A tankless unit may last about 20 years with proper maintenance. Actual service life depends on the model, water quality, installation, use, and maintenance history.
