Pockets of older Richmond Hill housing, especially the century homes around Mill Pond, can still have knob-and-tube wiring. This ungrounded system creates safety and insurance headaches. As an electrician in Richmond Hill we replace knob-and-tube with modern grounded wiring and coordinate the ESA permit and inspection.
Knob & Tube Wiring in Richmond Hill: local know-how
Knob-and-tube wiring is the original early-1900s system found in some of Richmond Hill's oldest homes. It has no ground, the insulation becomes brittle with age, and it was never designed for today's appliance and electronics loads, or for the modern insulation often packed around it. Many insurers now refuse coverage or charge more when knob-and-tube is present. We trace the active circuits, replace the old wiring with grounded cabling, install proper junction boxes and grounded receptacles, and remove the abandoned runs. Rewiring requires an ESA permit and inspection, which we arrange so you have documentation to show your insurer.
