Knob-and-Tube Wiring Replacement across Arkansas

Knob-and-Tube Wiring Replacement in Little Rock, AR

The Quapaw Quarter holds some of Little Rock's oldest homes, Victorians and early-1900s houses that sometimes still have knob-and-tube wiring, and Hillcrest and the Heights add 1910s to 1930s bungalows where it also turns up. Insurers often ask about it.

Knob-and-Tube Wiring Replacement in Fayetteville, AR

The Washington-Willow historic district and the streets around Wilson Park and Mount Sequoyah hold Fayetteville's oldest homes, built from the 1880s to the 1920s, and knob-and-tube wiring still runs through some of their attics and crawl spaces. Student rentals near Dickson Street often have old circuits extended piecemeal by many owners.

Older homes near downtown can have original or patched wiring and small services, and many houses near campus are rentals. Rapid growth brings steady demand for new circuits, EV chargers and panel upgrades.

What knob-and-tube wiring replacement involves

Knob-and-tube wiring was designed to release heat into open air. Over a century, its insulation becomes brittle, connections are often modified by later owners, and it has no ground conductor for modern three-prong outlets or GFCI-friendly appliances.

The biggest practical issue is insulation: blowing insulation into walls or attics around active knob-and-tube traps heat, so many insulation programs and contractors require it to be assessed or replaced first. Insurers also frequently ask about it.

Signs to look for

  • Ceramic knobs and tubes visible in the attic or basement
  • Two-prong outlets throughout the house
  • An insulation contractor or energy program requiring an assessment
  • An insurer asking about wiring type
  • Fuses or a small service alongside old wiring

What moves the price

  • How much knob-and-tube is still active
  • Plaster versus drywall walls
  • Attic and basement access
  • Number of floors
  • Panel upgrade at the same time
  • Wall patching and painting
