Knob-and-tube (K&T) wiring was the standard electrical wiring method used in homes built from the 1880s through the 1940s. While it was adequate for the minimal electrical demands of that era, knob-and-tube wiring is completely inadequate and potentially dangerous for modern electrical loads. The insulation on K&T wiring is typically rubber or cloth that becomes brittle and crumbles after decades, exposing bare conductors. The system lacks a ground wire, cannot support modern three-prong outlets, and was never designed for the amperage demands of today's appliances. Most critically, K&T wiring becomes a serious fire hazard when it contacts insulation -- a common problem in homes where blown-in or batt insulation has been added over the wiring. AJ Long Electric provides professional knob-and-tube wiring replacement throughout Northern Virginia, particularly in older homes in Arlington, Alexandria, Falls Church, and Fairfax City. Our electricians systematically replace K&T wiring with modern Romex copper wiring, adding proper grounding, AFCI protection, and sufficient circuits for modern electrical demands.
