Professional Knob & Tube Replacement for Rosslyn Homes

Rosslyn homeowners trust AJ Long Electric for professional knob & tube replacement services. With over 30 years serving Arlington County, we understand the unique electrical needs of high-rise condo, apartment, townhome homes throughout this neighborhood.

Many Rosslyn homes experience 1960s-1970s high-rise buildings with outdated electrical distribution systems, which can affect knob & tube replacement projects. Our licensed electricians are familiar with local construction styles and know how to address common challenges efficiently.

Knob-and-tube wiring can remain concealed across attics, basements, walls, and ceilings, often alongside later wiring changes. AJ Long Electric starts by tracing accessible active circuits, documenting conductor and insulation condition, identifying splices and overcurrent protection, and separating active wiring from abandoned material where that can be verified. The replacement plan is based on the circuits and areas actually identified, the loads the home now needs, panel capacity, grounding, required protection, and practical access routes. Fishing new cable through cavities may reduce openings, but historic plaster, trim, fire blocks, additions, and inaccessible junctions can require selective access. Electrical work, wall openings, finish restoration, insulation, and other-trade work are described as separate boundaries so the homeowner knows what is and is not included.

Every knob & tube replacement project we complete in Rosslyn receives the same attention to detail and commitment to safety that has earned us over 1,400 five-star reviews. We handle all Arlington County permits and inspections, ensuring your project meets current electrical codes.
