Understanding Knob and Tube Wiring: History and Function
What is Knob and Tube Wiring?
Knob and tube wiring is an early form of electrical wiring found in many heritage homes across Oakville and Canada. Installed from the late 1800s through the 1950s, this system utilizes porcelain knobs for guiding wires and tubes for insulation as wiring passes through joists. Wires are spaced apart, allowing heat to dissipate freely—a method considered safe at the time, but inadequate for modern homes. While the historical charm may add character to older residences, the knob and tube system lacks grounding and cannot safely accommodate today’s appliance loads, smart home devices, or increased demand on electrical wiring. Over time, insulation deteriorates, exposing wires and creating serious electrical safety hazards including fire or shock risk.
Where You’ll Find Knob and Tube in Oakville Homes
Owners of character homes should know how to spot knob and tube wiring. Typical signs include: two-prong, ungrounded outlets; visible ceramic or porcelain knobs and tubes in unfinished basements or attics; and older fuse boxes, sometimes adjacent to a modern electrical panel. Unlike today’s bundled, insulated modern wiring, tube wiring is usually single-strand and covered in cloth insulation, which becomes brittle over decades. It’s commonly found in areas less likely to be renovated—behind plaster walls, in attic crawlspaces, and beside original light fixtures. If your home’s wiring hasn’t been replaced since the mid-20th century, it’s crucial to have your property inspected by a certified electrician experienced in residential electrical upgrades.

Why Knob and Tube Replacement Oakville Is Critical
The Hidden Dangers: Fire & Safety Risks
The primary hazard with knob and tube wiring is its inability to safely handle today’s modern electrical demands. Overloaded circuits, deteriorated insulation, and amateur modifications yield a high fire risk. With no ground wire, the system can’t safely divert power surges, making shock and equipment damage more likely. In addition, porcelain knob or ceramic components may have become loose over time, further compromising electrical safety. Insurance statistics show that homes with outdated tube wiring systems see a markedly higher rate of electrical fires—a risk no homeowner wants to accept. The National Fire Protection Association recommends that homes with knob and tube wiring be fully rewired to meet current safety standards, ensuring the system is properly insulated, grounded, and compliant.
Insurance and Legal Barriers in Ontario
In Ontario, having knob and tube wiring often results in limited or denied home insurance coverage. Most insurers require full replacement of tube wiring prior to policy renewal or sale of the home. Electrical safety codes have changed significantly, and current Canadian standards prohibit installation of new tube wiring systems in residential or commercial properties. If you have a claim and your home contains knob and tube, reimbursement may be denied due to “known risks.” This makes knob and tube replacement not just a safety upgrade but a legal and financial necessity. Work with a licensed electrician to ensure the new system is installed to code, and receive proper documentation to share with your insurance provider and future buyers.
