Knob & Tube Wiring Removal

What Is Knob and Tube and Why You Need to Replace It?

Knob and tube, also known as open wires or K&T. This wiring method considered not safe to the point where many insurance companies will not insure the property. In fact, if you are planning to make any additions in your house, this type of house wiring is a violation of electrical building codes. A major concern here is missing grounding wire. This makes impossible to install GFCI outlets and prevent potential electrical shock. Also, this means outdated layout of plugs, switches, etc.

Most of the homes that were built in the 1900s to the late 1940s have a knob wiring. It is estimated that approximately 350,000 homes were built in Ontario with knob & tube wiring. If the K&T remains unchanged or has been carefully maintained by licensed electricians, this wiring method could still be in good condition. But unfortunately, this is rarely the case. While the wiring ages and deteriorates, porcelain knobs and tubes can break up. Old wires sag and fray, and the sheathing falls off, exposing the live wires. Despite the damage done by aging, most problems with K&T are caused by alterations made by handymen or inexperienced homeowner.
