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. We work carefully through attics, walls, and basements to remove old wiring with minimal disruption to your home's plaster walls and historic character. Every project includes full permitting, inspection, and detailed documentation for your insurance company.
