Pockets of older Vaughan, especially original homes in Thornhill village, Kleinburg, and parts of Woodbridge, can still contain knob-and-tube wiring. This ungrounded early wiring is a safety and insurance concern. We assess what's left, plan a phased replacement, and rewire with modern grounded circuits to current Ontario Electrical Safety Code.
Knob & Tube Wiring in Vaughan: local know-how
Knob-and-tube wiring was standard before the 1950s and survives in some of Vaughan's oldest properties around Thornhill and Kleinburg. It has no ground conductor, its insulation becomes brittle with age, and it was never designed for today's loads or for being buried under blown-in attic insulation, which traps heat. Many insurers in Ontario now refuse coverage or charge more when active knob-and-tube is present. We inspect attics, basements, and accessible walls to map what remains, then replace it with grounded copper wiring, new boxes, and modern receptacles. We work in phases to manage cost and disruption, pull the required ESA permit, and provide inspection documentation your insurer can accept.
