Why Knob & Tube Wiring Must Be Replaced

Older Davenport houses were built for a different era of electrical use, long before today’s kitchens, home offices, air conditioning, and high-demand appliances became standard.

No Ground Wire

Knob and tube systems were installed without a dedicated grounding path, so the electrical protection expected by modern outlets, devices, and appliances simply is not there.

Deteriorating Insulation

As the original cloth and rubber coverings age, they become dry, fragile, and prone to breaking apart, which can leave live conductors exposed inside concealed spaces.

Overloaded Circuits

These circuits were never meant to support the demands of current-day living, so even a modestly updated home can end up pushing them well past their safe capacity.

Insurance Cancellation

Many insurers treat active knob and tube as a serious underwriting issue, which can complicate renewals, delay purchases, or trigger requests for urgent upgrades.

Buried by Insulation

Because knob and tube relies on open air around the conductors, covering it with insulation traps heat and creates a condition that should not be left in service.

Reduced Home Value

Outdated wiring can become a major issue in real estate negotiations because buyers, inspectors, and lenders see it as a hidden cost that must be resolved.

Our Knob & Tube Rewiring Services

From full-home rewires in older Davenport houses to targeted upgrades where only part of the wiring remains original, we handle the complete scope of replacement work.

Full Home Rewire

We replace active knob and tube throughout the property and install modern cable systems using routing methods designed to reduce unnecessary wall and ceiling damage.

Partial Rewire & Targeted Circuits

If only certain rooms or branches still contain obsolete wiring, we can rewire those areas and integrate them correctly with the home’s newer electrical work.

Panel Upgrade

Many homes with knob and tube still rely on undersized services, so we often pair rewiring with a panel upgrade that better fits modern electrical demand.

ESA Permit & Inspection

All replacement work requires an ESA permit. We handle the application, coordinate inspection, and provide the certificate needed for your records and insurer.

Insurance Assessment Letter

If you need documentation quickly, we can inspect the property and provide written findings that explain the scope and condition of the active knob and tube wiring.

GFCI & AFCI Upgrades

As part of the rewire, we install the protection devices required for kitchens, bathrooms, living areas, and other spaces under the current electrical code.

Attic Insulation Clearance

If insulation is covering active knob and tube in the attic, we remove the obsolete wiring first so insulation work can move ahead safely and legally.

Pre-Sale Rewire

A completed rewire with ESA certification removes one of the biggest concerns raised by buyers, inspectors, and lenders during a home sale.

What Davenport Homeowners Say

Real feedback from rewiring projects in older homes around Davenport and nearby neighbourhoods.

“Our insurer wanted proof that the old wiring in our Regal Heights semi was being replaced. Kolji Bros moved fast, handled the permit, rewired the house, and got us the ESA paperwork we needed without any drama.”

“We bought an older house near Corso Italia and discovered active knob and tube in the attic and basement after closing. They rewired it, upgraded the panel, and kept the patching surprisingly limited.”

DP
Daniel P.Homeowner, Corso Italia

“Our triplex near Dovercourt Village had a mix of old wiring and messy additions from previous renovations. Kolji Bros sorted it out, cleaned up the panel layout, and explained every stage clearly.”

Knob & Tube Wiring FAQ Davenport

Answers to the questions we hear most from homeowners dealing with older wiring in Davenport homes.

It can be dangerous when it remains energized in an older house. The original insulation often dries out and breaks down, conductors may be exposed near framing, and the system has no grounding conductor for modern safety expectations. In older Davenport homes, hidden runs in attics and wall cavities are a common concern.
If your home dates from the early 1900s, there is a reasonable chance some original wiring is still present. Check unfinished basement ceilings, attics, and open framing for ceramic knobs, ceramic tubes, and cloth-covered two-wire conductors. A licensed electrician can determine whether the wiring is active, partially disconnected, or mixed with newer circuits.
The final cost depends on layout, square footage, access, finish materials, and whether the electrical panel also needs upgrading. Smaller homes may fall near the lower end of the range, while larger multi-storey properties with tight access or plaster walls cost more. For a full breakdown, visit our knob and tube rewiring cost guide.
Yes. A legal knob and tube replacement requires an ESA permit and inspection under the Ontario Electrical Safety Code. We handle the permit application and coordinate the inspection process so the paperwork is completed properly.
Insurance companies generally want proof that the work was completed under permit and passed inspection. Once the project is signed off, you receive an official ESA certificate that can be provided to your insurer.
In many cases, yes. We usually phase the work so much of the home stays usable, although there will be scheduled periods when certain circuits are off. On panel replacement day, the home normally experiences a longer temporary outage.
Many older homes can be completed in roughly 3 to 7 working days, depending on size and complexity. Smaller houses move faster, while taller homes and more intricate layouts take longer. We provide a realistic schedule in the written quote.
If active knob and tube is buried under attic insulation, that issue needs to be addressed before more insulation work proceeds. We remove the obsolete wiring first, then insulation upgrades can continue once the rewiring is complete and inspected.
