Why is Knob & Tube Wiring Considered Dangerous?
Age of wiring
Knob & tube wiring was used up until the 1940s. Today’s modern appliances and electronics consume more electricity and if you still have outdated knob and tube wiring, you are running the risk of overloading the wiring which can cause an electrical fire.
Insulation
Insulation was typically installed over the knob & tube wiring which increases the risk of fire. This extra layer of rubber cloth insulation has minimal space to disperse heat that builds up as current flows through the wires.
Alterations & Repairs
We see quite a few issues with knob & tube wiring that were due to DIY fixes or untrained handymen. These old systems are challenging to find parts for which often leads to band-aid solutions and improper alterations.
Absence of Ground Wire
Knob & tube wiring does not have a ground wire (two-pronged outlet) which makes it unsafe for modern three-pronged appliances and electronics.
Moisture
Aluminum knob & tube wiring is not suitable for moist environments. Areas that have been exposed to moisture can be dangerous and a shocking hazard.
Knob and Tube Wiring: A Brief Overview
Knob and tube wiring, a pioneering electrical installation method, was prevalent in North America from the late 1880s to the early 1940s. This system, characterized by its distinct separation of electrical conductors and its reliance on porcelain insulators (knobs) for running wires through open air and tubes to protect wires passing through wood framing, was the standard in residential electrical wiring for several decades.
Today, in Victoria, BC, knob and tube wiring is often encountered during the renovation of historical homes. While it was considered highly advanced for its time, modern electrical standards and safety requirements have evolved, rendering knob and tube systems outdated. Homeowners and electricians in Victoria face unique challenges when dealing with knob and tube wiring, such as ensuring compatibility with modern appliances, meeting current electrical codes, and addressing potential insurance and safety concerns. Electing to upgrade to contemporary wiring systems not only enhances electrical safety but also supports the functionality of modern electronic devices and home automation systems, making it a crucial consideration for preserving Victoria’s rich architectural heritage while ensuring the safety and convenience of its residents.

What Victoria Homeowners Ask About Knob & Tube Wiring
Is knob and tube wiring actually dangerous, or only a problem if something goes wrong?
Knob and tube wiring is genuinely dangerous, not just a risk in worst-case scenarios. It has no ground wire, so electrical faults have no safe path and modern appliances are incompatible. The cloth insulation deteriorates with age, and packing insulation around it traps heat directly against the wires.
Will having knob and tube wiring affect my home insurance in BC?
Yes, having knob and tube wiring will affect your home insurance in BC. Most insurers will either decline to cover a home with active knob and tube wiring or require its replacement before they will issue or renew a policy. Homeowners who do find coverage with it in place typically pay significantly higher premiums until the rewiring is complete.
Does rewiring a home with knob and tube mean opening up all the walls and ceilings?
Not with the right contractor. Lenius & Osborn have performed hundreds of knob and tube rewires across Victoria using remote cameras and specialized tools that allow new wiring to be run without cutting open walls or ceilings in most cases. The entire team is trained in non-destructive techniques, and most jobs finish without any painting or patching.
Do I need a permit to replace knob and tube wiring in Victoria?
Yes, a permit is required and it is pulled through Technical Safety BC. All electrical work in BC must be performed by a licensed electrician, and the completed work is inspected before sign-off. Lenius & Osborn handle the permit process as part of the job, so you do not need to navigate that separately.
Can I add insulation to my walls if the house still has knob and tube wiring?
No, and this is one of the more serious risks with knob and tube wiring. The system was designed to dissipate heat into open air, so packing insulation around it traps heat against the wires and significantly increases the fire risk. Rewiring needs to be completed before any insulation work goes ahead.
Can I sell a house in Victoria that still has knob and tube wiring?
You can sell a house in Victoria with knob and tube wiring still in place, but it creates real obstacles for buyers. Most BC insurers will not cover a home with active knob and tube, and without insurance a buyer cannot secure a mortgage, which removes a significant portion of the market. Many Victoria sellers choose to complete the rewire before listing because it eliminates the single biggest barrier to a straightforward sale.
What drives the cost of a knob and tube rewire?
The main factors are the size of the home, how much of the wiring is still active, the accessibility of walls and ceilings, and whether a panel upgrade is needed at the same time. Permit and inspection fees through Technical Safety BC are also part of the total. Lenius & Osborn provide free quotes and will give you a clear picture of what your specific home requires before any work begins.
Is it safe to keep knob and tube wiring if it hasn't caused any problems yet?
Knob and tube wiring is not safe simply because it has not caused visible problems yet. It degrades over time regardless, and the risks compound with age, past DIY modifications, and the demands of modern electrical loads the system was never designed to handle. Most BC insurers treat active knob and tube as a liability regardless of its apparent condition.
How long has Lenius & Osborn been doing knob and tube rewiring in Victoria, and why does that matter?
Lenius & Osborn have been specializing in knob and tube rewiring since the early 1990s, and the team carries over 80 years of combined experience in this specific type of work. That depth matters in Victoria because pre-1945 character homes present challenges that generalist electricians encounter infrequently. The non-destructive techniques the team uses have been refined across hundreds of local rewires, which is why the majority of their jobs finish without wall or ceiling damage.
Do you handle knob and tube rewiring in Oak Bay, Saanich, and the surrounding areas?
Yes, Greater Victoria is the core of what Lenius & Osborn do, and that includes Oak Bay, Saanich, and the surrounding municipalities. Given the concentration of pre-1945 character homes across these neighbourhoods, knob and tube rewiring makes up a significant part of the work they do throughout the region.
