What should a homeowner do if their home has knob and tube wiring?

A homeowner with knob and tube wiring should consider having it inspected and possibly replaced because knob and tube wiring can pose several safety risks. This type of electrical system, commonly used in homes built before the 1940s, was not designed to handle modern electrical loads and lacks grounding. As a result, it can lead to overheating, electrical shorts, and even fires if overloaded.

Having a professional inspection allows a qualified electrician to evaluate the condition of the wiring, identify any hazards, and assess whether it needs to be replaced. If the wiring is found to be in poor condition or if significant renovations are planned that require updated electrical systems, replacement is often recommended to ensure safety and compliance with current building codes. Therefore, this approach prioritizes safety and informed decision-making over simply leaving potentially hazardous wiring in place or conducting a replacement without professional evaluation.
