Knob-and-Tube Wiring in Vancouver Homes: Should You Replace It?
Character homes from Kitsilano to Burnaby Heights are beautiful. The wiring behind their plaster walls is often 90 years old. Here is what to do about it.
How to spot knob-and-tube in your home
Knob-and-tube (K&T) wiring was standard in Vancouver homes built between roughly 1900 and 1945. In the attic you will see individual black cloth-covered conductors run through white porcelain tubes and knobs. Under the house, you will see the same pattern between the joists. There is no ground wire, and the insulation degrades badly where it has been buried under blown-in attic insulation.
If your home has two-prong outlets, screw-in fuses in the basement, or push-button switches, there is a strong chance active K&T is still in the walls even if some circuits have been updated.
The insurance problem
Most major Canadian insurers will not write a new policy on a home with active knob-and-tube, and many will non-renew existing policies at inspection. Some will offer coverage only after a licensed electrician certifies the K&T is de-energized or removed, with photos and permit paperwork.
That certification is not a form we hand out - it is the outcome of a proper inspection, disconnection at the panel, and where required, a full or partial rewire pulled under permit and closed out by Technical Safety BC.
Full rewire vs staged remediation
A full rewire replaces every branch circuit with modern NMD90 cable, installs grounded outlets, adds AFCI and GFCI protection where the CEC requires it, and finishes with a new 200 amp panel. This is the cleanest outcome and the strongest position for insurance and resale.
Staged remediation is often the better choice during a phased renovation - rewire the kitchen and main bath now, the upstairs bedrooms when you refinish them, and the basement when you develop it. We plan the sequence so nothing gets buried twice.
Working in Vancouver character homes
Fishing new wiring through plaster walls, T&G ceilings, and shiplap without tearing up finished rooms is a craft. Our rewire crews specialize in East Vancouver, Kitsilano, Mount Pleasant, New Westminster, and North Burnaby heritage stock. We work with drywallers and painters we trust so patchwork disappears when the job is done.
