Kingsway homeowners are increasingly being asked by insurers to replace active knob & tube wiring. Book a free assessment today
Knob & Tube Wiring Replacement Kingsway
Kingsway is known for mature tree-lined streets, detached family homes, and many older properties built before the 1960s near Old Mill, Bloor Street West, and the Humber corridor. Those character homes often still hide original knob and tube in attics, basement ceilings, and wall cavities. Our ESA-licensed electricians replace outdated wiring with modern, code-compliant systems so your Kingsway home is safer, easier to insure, and ready for today’s electrical load.

Why Knob & Tube Wiring Must Be Replaced
Across Kingsway, Old Mill, and Sunnylea, older homes can still contain active wiring systems that were designed for a very different era. They were never intended to support modern kitchens, HVAC equipment, home offices, or the electrical demand of today’s family homes.
No Ground Wire
This wiring method only carries hot and neutral conductors, so modern appliances and receptacles do not get the grounding protection expected in a current code-compliant system.
Deteriorating Insulation
After decades in walls and ceilings, the old rubber and cloth wrapping often dries out and flakes apart, leaving conductors vulnerable around wood framing and hidden junction points.
Overloaded Circuits
Many older circuits were sized long before microwaves, induction ranges, air conditioning, EV charging, and multiple entertainment systems became part of everyday life.
Insurance Cancellation
Active knob and tube is frequently flagged during renewals, purchases, and renovations, and many homeowners are told to replace it before coverage can continue without issue.
Buried by Insulation
This system was meant to dissipate heat in open air. When later attic insulation surrounds active runs, heat buildup becomes a much bigger concern and the installation no longer meets modern expectations.
Reduced Home Value
Buyers, inspectors, and lenders often treat old active wiring as a major deficiency, which can complicate negotiations, delay closings, and weaken resale appeal.

Our Knob & Tube Rewiring Services
From full-home rewires in Kingsway to focused upgrades in Old Mill and Humber Valley Village, we handle the entire scope of replacing unsafe legacy wiring with a clean, permit-ready installation.
Full Home Rewire
We remove active knob and tube throughout the property and install new NMD-90 wiring, outlets, switches, and properly organized circuits with as little disruption as possible.
Partial Rewire & Targeted Circuits
If only part of the house still contains old wiring, we can isolate those sections, rewire them properly, and integrate the work with your existing modern electrical system.
Panel Upgrade
Many older homes still have undersized or outdated panels. We often pair rewiring with a 200A service or panel upgrade so the house can safely support today’s electrical needs.
ESA Permit & Inspection
All replacement work is performed under permit. We arrange the ESA process, coordinate inspection, and provide the paperwork needed for your records and insurer.
Insurance Assessment Letter
If an insurer needs confirmation quickly, we can inspect the wiring conditions and provide a written assessment that clearly outlines what remains active and what should be replaced.
GFCI & AFCI Upgrades
As part of the modernized installation, we add the protection required for kitchens, bathrooms, exterior circuits, bedrooms, and other locations governed by current code rules.
Attic Insulation Clearance
When active knob and tube is buried in attic insulation, we remove the wiring first so insulation upgrades can move ahead without leaving unsafe legacy conductors in place.
Pre-Sale Rewire
Planning to sell? We can complete the work before listing or closing so buyers, inspectors, and lenders are not stalled by an outdated electrical system.
