How to recognize the Knob and Tube?
During the first half of the XX-th century, the Knob and Tube wiring system was King in today's Toronto, Etobicoke, Mississauga and the GTA. Knob and Tube is a whole house network of single wire conductors supported on a large number of small ceramic tiles (tubes) and many small cylindrical insulators (knobs). When entering an electrical outlet or device box each wire has its own separate opening. Generally, an electrical conductor is insulated with a cotton insulation and there are additional semi rigid cotton tubes pulled over some parts of the conductor.

Why is the Knob and Tube unsafe?

Cotton insulation on the Knob and Tube installations has never been great and after many decades of exposure to significant environmental deterioration, sometimes it is simply non existent. A bonding conductor (grounding in popular terms) never existed in the Knob and Tube system and Knob and Tube is inherently unsafe. Add to the above list of facts, over many decades of use the loads applied to the household system grew over and over again, topping the system capacity. This would be the perfect setup for starting an electrical fire hidden somewhere in the wall or in the ceiling.

Do I need to get rid of the Knob and Tube?

The simple answer is YES! Your family's safety requires an update of your houses' electrical system to today's standards. Your home insurance company will force you to recognize it sooner or later. Home insurance companies have a really good reason to make sure houses have no active Knob and Tube wiring. They pay out millions of dollars to the owners of burned down houses. The Green Electrician can certify how much of your home electrical installation is Knob and Tube, if any. Please note, that not every outdated, old looking electrical installation is technically Knob and Tube. Some of the installations dated from 1940-ties and later could be grounded and good enough to today's home insurance standards.

Can The Green Electrician rewire the Knob and Tube?

The Green Electrician removed Knob and Tube from dozens of houses in Toronto, Etobicoke, Mississauga and the GTA, and has extensive experience. There are tens of thousands of homes in Toronto, Etobicoke, Mississauga nad the GTA waiting for the Knob and Tube to be removed and many electrical companies already removing Knob and Tube. The Green Electrician may not be the cheapest around, but is experienced and reliable. We will move in for a week or two, depending on the project size and during that period of time some parts of the house could become messy. In the process of pulling the new wiring we are going to cut several small holes in the house walls and ceilings. The Green Electrician will close those access cutouts, but generally a visit from your favorite plasterer and painter will be required afterwards.
