Knob & Tube Wiring Replacement Etobicoke
Etobicoke has a wide range of housing, from detached family homes and post-war bungalows to townhouses, semis, and waterfront condo communities near Lake Ontario. Many of the older houses across the district still hide original knob and tube wiring in attics, basement ceilings, and finished wall cavities. Our ESA-licensed electricians replace that outdated wiring with a modern code-compliant system so your Etobicoke home is safer, easier to insure, and better prepared for today’s electrical demand.

Why Knob & Tube Wiring Must Be Replaced
Across Etobicoke, especially in Mimico and The Kingsway, many older houses still rely on electrical systems that were installed long before modern kitchens, cooling equipment, home offices, and everyday electronic loads became standard.
No Ground Wire
This older wiring method only carries hot and neutral conductors, so modern outlets and appliances do not get the grounding protection expected in a current electrical system.
Deteriorating Insulation
The original cloth and rubber covering often dries out, splits, and crumbles with age, leaving energized conductors more exposed inside hidden framing cavities.
Overloaded Circuits
These circuits were never designed for the combined demand of modern appliances, chargers, portable cooling, computers, and the number of devices now common in family homes.
Insurance Cancellation
Active knob and tube often becomes a problem during policy renewals, refinancing, or resale, and owners are frequently told to replace it before full coverage continues.
Buried by Insulation
Knob and tube relies on open air around the conductors, so once attic insulation surrounds active runs, heat can build up in a way the system was never meant to handle.
Reduced Home Value
Home inspectors, buyers, and lenders often treat active knob and tube as a major deficiency, which can delay negotiations and complicate financing or closing.

Our Knob & Tube Rewiring Services
From full rewires in Alderwood to targeted upgrades around Islington-City Centre West and Humber Bay Shores, we handle the complete scope of replacing unsafe legacy wiring in older Etobicoke homes.
Full Home Rewire
We remove active knob and tube throughout the house and install a complete new wiring system designed for present-day lighting, receptacles, appliances, and household demand.
Partial Rewire & Targeted Circuits
If only specific areas still contain active legacy wiring, we can isolate those sections and replace the circuits that still require correction.
Panel Upgrade
Many older homes need panel improvements at the same time so the new wiring has proper capacity, circuit protection, and cleaner organization.
ESA Permit & Inspection
We manage the ESA permit and inspection process so the finished work has the documentation buyers, lenders, and insurers commonly ask for.
Insurance Assessment Letter
If your insurer needs confirmation quickly, we can inspect the property and provide a written assessment explaining what remains active and what must be replaced.
GFCI & AFCI Upgrades
We install the protective devices required for kitchens, bathrooms, bedrooms, exterior outlets, and other areas covered by current code rules.
Attic Insulation Clearance
Where insulation is covering active knob and tube, we complete the electrical replacement first so the attic can be upgraded safely afterward.
Pre-Sale Rewire
We help sellers remove a major electrical concern before listing or closing so the transaction is less likely to stall over outdated wiring issues.
