Knob & Tube Wiring Replacement in Asheville
Licensed Residential Rewiring for Buncombe, Henderson & Transylvania Counties
Knob and tube wiring was the standard residential electrical system in American homes from the 1880s through roughly the 1940s. If your Asheville home was built before 1950, there’s a real chance this wiring is still active behind your walls. Neighborhoods like Montford, Kenilworth, and Chestnut Hill have a high concentration of these older homes. At iFix Electric & Plumbing, our licensed electricians handle knob and tube wiring replacement for residential properties throughout Buncombe, Henderson, and Transylvania Counties.

Why Knob & Tube Wiring Is a Problem in Older Homes
The insulation on knob and tube wiring is cloth and rubber. After 70 or more years, that material becomes brittle and cracks, exposing live conductors inside walls and attic spaces. That degradation alone is a serious fire and shock hazard.
But deteriorating insulation isn’t the only issue. Knob and tube wiring has no ground conductor, which means grounded appliances, surge protectors, and GFCI outlets can’t function as intended on these circuits. The system also wasn’t designed for the electrical load of a modern household. Every time a homeowner runs extension cords to compensate or plugs in high-draw appliances, the original circuits absorb more than they were built to handle. When attic insulation is added over exposed knob and tube runs, it traps the heat the wiring depends on open air to release, creating an immediate fire risk.
Our Knob & Tube Replacement Process
Every project starts with a thorough assessment. We map existing circuits, identify active knob and tube runs, and determine the full project scope before any work begins. From there, we pull the required permits through the City of Asheville Development Services. Permitted, inspected rewiring is standard for every major project we complete.
In homes with plaster-and-lath walls, common throughout older Asheville neighborhoods, we route new wiring through attics, basements, and crawl spaces where possible. This approach limits the need to open finished surfaces, though we’re upfront about where access points may be unavoidable. We organize work by zone so most of the home retains power while active sections are being rewired, and we coordinate the schedule around what works for you.
Older panels from the knob and tube era often lack the capacity for new copper wiring and modern appliance loads. During the assessment phase, we evaluate whether a panel upgrade makes sense alongside the rewiring work. Once all work is complete, a City of Asheville electrical inspector signs off on the project, giving you documented confirmation that the work meets current code. Every rewiring project is backed by our lifetime workmanship warranty.
