The cost of disconnecting and capping the wires of a hardwired stove can vary depending on several factors, such as the location, local labor rates, and the complexity of the job. However, in most cases, $500 seems significantly high for a simple stove disconnection and capping of wires.
The process of disconnecting a stove usually involves turning off the power, disconnecting the electrical wiring from the power source, and capping the live wires safely to prevent any potential hazards. This is typically not a time-consuming or complex task for a qualified electrician.
To get an accurate estimate, it's best to contact a few licensed electricians in your area and ask for quotes specifically for disconnecting and capping the wires of a hardwired stove. By comparing multiple quotes, you can get a better idea of the average cost for this service in your location.
Keep in mind that electrical work should always be performed by a licensed professional to ensure safety and compliance with local electrical codes and regulations. Trying to do this type of work yourself or hiring unqualified individuals could lead to serious safety risks and potential damage to your electrical system.
