Why Replace Knob and Tube Wiring?

Knob and tube wiring should be replaced for several important reasons. One major issue is that it does not have grounding. Grounding safely directs excess electricity, which lowers the risk of electrical shocks or fires. Without grounding, your home's wiring is more likely to suffer from dangerous surges. The insulation that is used around knob and tube wiring can also wear out after some time. This can expose wires, creating a risk of them touching other materials, which may cause overheating or fires. These older systems also can't keep up with the electrical needs of modern homes. They were not designed to support air conditioners, refrigerators, dishwashers, or the many electronic devices we use every day. If you notice flickering lights, breakers that trip often, or discolored outlets, your home might still have this old wiring. If you haven't had a wiring inspection in many years, it's time to think about replacing it.

What Does Knob and Tube Replacement Involve?

Rewiring a home to remove knob and tube wiring begins with a thorough inspection. An electrician from our team will look at your current system, identify where old wiring is still active, and create a plan for replacement. This plan often includes removing visible old wiring, installing modern electrical wire with proper insulation and grounding, and ensuring all connections are secure. Once the new wiring is in place, we perform detailed testing to ensure everything is working correctly and safely. The replacement process also includes updating other parts of your electrical system, such as outlets and light switches. Mr. Electric of Tucson completes all rewiring work so that it is up to safety standards and building codes.

How Long Does Knob and Tube Rewiring Take?

The timeline for a rewiring project varies based on the size of your home and how accessible the existing wiring is. Smaller homes with good access to wiring pathways may be completed in several days, while larger or more complex homes could take over a week. Factors like wall structure, attic space, and whether drywall needs to be removed all impact the duration of the project. We strive to minimize disruption throughout the process, keeping the work areas clean and coordinating closely with homeowners to ensure a smooth experience.

What Is Knob and Tube Wiring?

Knob and tube is a wiring system that was installed in houses built in the early 20th century. It consists of individual wires that are strung through ceramic knobs for support and fed through ceramic tubes when passing through framing. It was considered an effective solution for its time, offering basic electrical functionality in an era before modern appliances became widespread.
Today, knob and tube wiring is no longer compliant with modern electrical codes due to several safety and capacity concerns. It lacks grounding, has minimal insulation, and is not designed to handle the number of devices or the level of power required by today’s households. Because of this, insurance companies generally will not cover homes with this outdated system until it has been fully replaced.
