Tank Leaks and Pressure Problems in Janesville
Even gas water heaters can develop tank leaks, often due to corrosion from hard water or high water pressure. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. While some leaks may call for a replacement, minor leaks or pressure relief valve issues can often be repaired. Our team checks the extent of the damage, inspects the anode rod and addresses pressure imbalances to prevent further complications in your Janesville home.

Commercial Gas Water Heater Repair in Janesville, WI
Businesses in Janesville, WI depend on a constant supply of hot water for their operations. Our team is equipped to handle the larger, more complex gas water heater systems found in commercial settings. We understand the need for minimal downtime and provide efficient, durable repairs to keep your business running without interruption.
Gas Control Valve Replacement in Janesville, WI
The gas control valve regulates temperature and shuts off gas if the pilot goes out. Newer valves from Honeywell and White-Rodgers use status lights that blink codes when something goes wrong. If the valve itself has failed, we replace it with an exact match or approved universal model. We leak test and confirm temperature control afterward.
Propane Water Heater Repair in Janesville
Rural properties often run water heaters on propane rather than natural gas. Propane units use different orifices and regulator pressures, and incorrect conversions cause sooting and poor performance. We confirm the correct parts are installed and repair pilots, valves and burners. We also check tank regulators for proper pressure.
Water Heater Tank Leaks and Pressure Issues in Janesville, WI
While gas water heaters are robust, tank leaks or pressure problems can occur. We can often fix small fitting leaks or replace relief valves if pressure is too high. If the tank itself is compromised due to rust or old age, a replacement might be the more sensible long-term solution. We will provide an honest assessment of the repair options for your Janesville, WI home.
Gas Water Heater Repair Cost in Janesville, WI
Thermocouple and pilot repairs usually cost $150 to $350. Gas control valve replacement often runs $350 to $700, and power vent blower repairs can range from $400 to $800. A new gas tank installed usually costs $1,600 to $3,000 depending on size and venting. We help you decide based on tank age and condition.

Frequently Asked Questions About Gas Water Heater Repair in Janesville
The cost of gas water heater repair in Janesville, WI can vary widely depending on the issue. Minor repairs like a thermocouple replacement might range from $150 to $350, while more complex issues such as a gas valve replacement could be $400 to $800 or more. We always provide a detailed, upfront estimate once we diagnose the problem.
A thermocouple is a safety device in a gas water heater that senses if the pilot light is lit. If it doesn't detect heat, it shuts off the gas supply to prevent gas leaks. A faulty thermocouple is a very common reason for a pilot light not staying lit and is a vital safety component.
Most common gas water heater repairs can be completed within 1 to 3 hours. More complex issues, or cases where special parts need to be ordered, could extend the timeline. We aim for efficiency without compromising safety or quality.
While some minor issues might seem DIY friendly, working with gas appliances carries serious safety risks, including gas leaks and carbon monoxide poisoning. It is always best to call a licensed professional for gas water heater repair to ensure safety and proper function, and to stay within local codes.
