Knob and tube wiring (K&T) was the standard electrical system installed in North American homes from the 1900s to the 1950s. It used porcelain knobs and tubes to run wires through walls and ceilings. While it was effective for its time, it’s now considered unsafe and obsolete for modern electrical demands.
Knob and tube wiring lacks a ground wire, can’t handle today’s electrical loads, and its insulation becomes brittle over time — increasing the risk of short circuits, shocks, and fire hazards.
If your home still has knob and tube wiring, replacing it isn’t just a suggestion — it’s a safety necessity.
Here’s why homeowners across Toronto trust Pioneer Electrics for professional replacement:
Old insulation and ungrounded wires can overheat easily, leading to electrical fires. Replacing the wiring ensures your system is stable and protected against overcurrent.
Many insurance companies refuse coverage or charge higher premiums for homes with knob and tube wiring. After replacement, you’ll receive proper ESA certification to confirm your system meets modern safety standards.
Modern homes use significantly more power — from air conditioners to smart appliances. Old knob and tube systems were never designed for this. Rewiring allows for safe operation of all your devices without tripping breakers.
Updating your electrical wiring not only keeps your family safe but also increases your home’s resale value and marketability.
At Pioneer Electrics, we provide complete end-to-end knob and tube replacement solutions for residential and heritage properties throughout Toronto.
