Why Knob-and-Tube Removal Cost Varies in Duluth

Knob-and-tube removal cost in Duluth depends overwhelmingly on access. Pulling the old wire is only half the work — we have to route a new circuit in its place. In a room with an unfinished basement below and an unfinished attic above, that's straightforward: about $700-$1,000. In a second-floor bedroom with plaster walls and a finished space above and below, every junction needs an access cut, and the new wire has to be fished through original framing, lath, and old insulation. That can push a single room to $1,800-$2,000. If the attic has loose blown-in insulation that was added after the original knob-and-tube was installed, NEC 394.12 prohibits leaving it — it must be removed during demo and reinstalled, which adds cost.

What Drives the Price

  • Plaster vs drywall walls
  • Number of circuits in the room
