What Is Knob-and-Tube Wiring and Why Replace It?

Knob-and-tube (K&T) was the standard residential wiring method from the 1880s to the early 1950s. It consists of single-insulated copper conductors run through ceramic knobs (in walls) and tubes (through joists), with no grounding wire.

While K&T was safe when new, it is now considered a serious hazard because:

• No ground wire → unsafe for modern three-prong appliances and electronics
• Insulation degrades and becomes brittle over decades → risk of arcing and fire
• Cannot support today’s electrical loads (air conditioning, computers, EV chargers, etc.)
• Most insurance companies now restrict or deny coverage on homes with active K&T wiring
• Prevents installation of modern safety devices like AFCI breakers and whole-home surge protection

In older Oshawa and Whitby neighbourhoods especially, active knob-and-tube is one of the top reasons homes fail insurance inspections or home sales.

Our Knob-and-Tube Replacement Services

Beetham Electric offers full-service, minimally invasive knob-and-tube removal and modern rewiring:

• Complete house re-wire – Replacing all active K&T with new NM-B (Romex) copper wiring and grounding
• Partial rewiring – Targeting specific areas (e.g., kitchen, second floor, basement) while safely abandoning remaining K&T
• Panel upgrade – Almost always required (100-amp to 200-amp service) during full re-wires
• New grounding system – Essential for safety and modern appliance use
• AFCI & GFCI protection – Added throughout the home per current Ontario Electrical Safety Code
• Integration with other upgrades – Pot lights, EV charger circuits, smart home wiring, surge protection, smoke/CO alarms

We work carefully to minimize drywall damage, protect your hardwood floors and heritage trim, and leave your home cleaner than we found it.

Signs Your Durham Home May Still Have Active Knob-and-Tube

• Built before 1955 (common in downtown Oshawa, older Whitby, Ajax, and Pickering)

Durham Region Knob-and-Tube Tips

• Never add new wiring to an active K&T system — it’s against code and extremely dangerous
• Get a professional assessment before buying or insuring an older home
• Combine K&T removal with insulation upgrades (many homes lose the blown-in insulation benefit when K&T is abandoned)
• Take advantage of off-peak hydro rates once your home can safely handle modern loads
