Many of Scarborough's oldest homes, particularly pre-war and early post-war houses in Birch Cliff and Cliffside, still contain knob-and-tube wiring. This ungrounded system can cause insurance headaches and safety concerns. As an electrician in Scarborough, we replace knob-and-tube with modern grounded wiring.

Knob & Tube Wiring in Scarborough: local know-how

Knob-and-tube wiring lacks a ground conductor and was never designed for today's loads or for contact with the blown-in insulation found in many renovated Scarborough attics. Insurers increasingly refuse coverage or demand replacement when they find it. We trace the active knob-and-tube circuits in your home, plan a replacement route that minimizes wall damage, and rewire with grounded cable, new boxes and properly rated devices. In occupied Scarborough homes we phase the work room by room to keep power on where possible. Where required, we coordinate ESA inspection so you have documentation to provide your insurance company once the old wiring is removed.

Frequently asked questions

My Scarborough insurer flagged knob-and-tube wiring. What are my options?
Most insurers require active knob-and-tube to be replaced with grounded wiring. We can inspect what's still live, give you a replacement plan, and provide ESA-inspected documentation afterward so you can confirm removal to your insurance provider.
Can knob-and-tube be replaced without gutting my house?
Often, yes. In Scarborough homes we fish new wiring through accessible cavities, attics and basements to limit drywall removal. Some patching is usually unavoidable, but we plan routes to keep it minimal and walk you through where access is needed.
Will my insurance company really require this?
Many GTA insurers either decline coverage or charge more for homes with active knob-and-tube. We can provide the documentation insurers commonly ask for once the wiring is replaced.
Do you have to tear open all my walls?
Not necessarily. Experienced rewiring is done with minimal openings — fishing wire through existing cavities where possible. We aim to limit drywall damage and will set expectations before starting.
