Knob & Tube Wiring Replacement High Park
High Park features a large concentration of older west-end housing, including Edwardian and Victorian detached homes, brick semis, tree-lined character houses near High Park North, and long-held properties around Bloor Street West, Parkside Drive, and the streets connecting toward Roncesvalles and Swansea. Many of these homes still hide active knob and tube wiring behind plaster walls, above finished ceilings, and inside basements or attics altered over decades of renovations. Our ESA licensed electricians replace outdated wiring in High Park homes with modern, code-compliant systems built for today’s electrical demand, safety standards, and insurance expectations.

Why Knob & Tube Wiring Must Be Replaced
Many High Park homes were built in an era before electric heating loads, home offices, large kitchen appliance circuits, and the heavier day-to-day demand created by renovated family homes.
No Ground Wire
These early electrical systems were installed without a grounding path, leaving less protection when faults occur and providing fewer safeguards for today’s plugged-in equipment.
Deteriorating Insulation
Over time, the original insulation can harden, crack, and fall away, exposing energized conductors inside wall cavities, ceilings, and structural framing.
Overloaded Circuits
Older branch circuits in High Park homes are frequently expected to serve renovated kitchens, added receptacles, laundry equipment, and other loads they were never sized to support.
Insurance Cancellation
Insurers often treat active knob and tube as a major concern, which can result in strict deadlines, limited terms, or refusal to continue standard coverage.
Buried by Insulation
When attic insulation covers active knob and tube conductors, the old open-air cooling design no longer works properly, which creates a dangerous overheating condition.
Reduced Home Value
Active legacy wiring can slow down a sale, create concerns during buyer inspections, and make financing or insurance more difficult for the next owner.
⚠️ Is Your Insurer Threatening Cancellation?
We can inspect your High Park property, document what wiring is still active, and help move the rewiring project forward quickly so you have the records your insurer may request.

Our Knob & Tube Rewiring Services
From full-house rewires in High Park to focused upgrades near Roncesvalles and Bloor West Village, we handle older-home electrical replacement from start to finish.
Full Home Rewire
We replace active knob and tube wiring throughout the home and install a modern electrical system better suited to current code and everyday use.
Partial Rewire & Targeted Circuits
When only certain parts of the property still depend on active old wiring, we can isolate and replace those circuits without enlarging the job unnecessarily.
Panel Upgrade
Many older High Park homes also need a panel upgrade so the finished electrical system has proper capacity, safer protection, and clearer circuit organization.
ESA Permit & Inspection
We handle the permit process, complete the work to code, and coordinate inspection so the project closes with proper approval documentation.
Insurance Assessment Letter
If your insurer needs documented findings on active legacy wiring, we can inspect the property and provide written information to support your file.
GFCI & AFCI Upgrades
As part of the overall electrical upgrade, we add modern protective devices needed for safer operation and better alignment with current code requirements.
Attic Insulation Clearance
Where knob and tube conductors have been buried beneath insulation, we remove the unsafe wiring first so the attic can be handled correctly afterward.
Pre-Sale Rewire
Replacing active knob and tube before listing can reduce buyer concerns, improve insurability, and help keep a future sale from stalling over electrical issues.

Why Homeowners Choose Kolji Bros
High Park homes often combine original construction, plaster finishes, finished basements, additions, and difficult wiring routes that require careful planning during a rewire.
Older Home Experience
We work in aging west-end properties where plaster walls, attic constraints, partial past rewires, and finished interiors all affect how the project should be carried out.

Clean, Planned Work
We stage the work carefully, protect occupied areas, and reduce unnecessary disruption so the home remains more manageable while rewiring is underway.
Clear Communication
We explain what remains active, what should be prioritized, and how access, panel work, and existing finishes shape the timeline and scope.
Code-Compliant Upgrades
We do more than remove old conductors; we upgrade the affected system with proper protection, permit coverage, organization, and inspection-backed completion.
Trusted Local Reputation
Homeowners call us when they want licensed electricians who understand older wiring risks and finish the job carefully rather than rushing through shortcuts.

Recent clients in High Park, Roncesvalles, and Swansea called us when aging wiring began affecting renovations, insurance deadlines, and everyday electrical reliability.
