Knob and tube wiring was used in Vancouver and Lower Mainland houses between 1900 and 1949. With the age of this wiring, and its deterioration over time, wire and tube is considered and can be problematic. Most insurance companies will not insure homes that have knob and tube wiring present.
By itself, knob and tube wiring is not a problem. If left undisturbed, it should function as designed. However, many of today’s homes (with our many appliances and devices) exceed the electrical load limitations of knob and tube wiring. Home renovators may add lights and circuits, meaning the wires now have to handle more current and more heat. Renovators adding insulation, homeowners doing installations and performing poor do-it-yourself fixes, and/or having mice eat the knob and tube fabric wrapping can leave hot, exposed wires in a wood-framed house. The knobs and tubes themselves are ceramic insulators, but, the reality of insulation, dust, and wood framing close to them is where danger lies.
Most insurance companies consider wire and tube a fire hazard, and will not insure a home that has wire and tube inside.
To know if you home has knob and tube wiring present, you need to look or have an electrician or home inspector look for you. Often, you can see knob and tube wiring if you look in your home’s attic.
If you own or are buying a home with knob and tube wiring present, contact Nightingale Electrical Service to remove it. Our certified electricians are experts in handling knob and tube removal projects. During the removal, the old wiring will be replaced with new copper wiring which will meet electrical safety regulations. Nightingale also assures proper grounding of the wiring. While the electrician is working in your home, you can also get them to look into important items like wired surge protection, electrical panel upgrades, and proper counts, function and location of wired carbon monoxide and smoke detectors. It’s more efficient to do these things during the same renovation project, to save time, labour and wall and ceiling repair costs.
