We Replace Knob and Tube Wiring in Seattle Homes

Why Knob and Tube Has to Go

Seattle has one of the highest concentrations of knob and tube wiring of any major American city, simply because so much of the housing stock went up between 1900 and 1945 and was never fully modernised. Pull back the attic insulation in a Ballard or Beacon Hill bungalow and there is a good chance you will find ceramic knobs, ceramic tubes and cloth-covered conductors still carrying current.

Knob and tube was competent engineering for its era. The problem is that the era assumed a few light fixtures and no grounding conductor, and it relied on the wires running through open air to shed heat. A century later the cloth insulation is brittle, the system has usually been extended with unsafe splices by previous owners, and — critically — the code prohibits burying it in insulation because that traps the heat it was designed to release.

That last point is what catches most homeowners. You cannot properly insulate an attic that still has active knob and tube, which means you are stuck choosing between an energy-efficient home and a legal one. Replacement resolves both problems at once, and right now a knob and tube rewire comes with $2,100 off.
