How long does it take to replace knob-and-tube wiring in an older Vancouver house?

Replacing knob-and-tube wiring in a typical Vancouver character home takes 3-7 days for the electrical work itself, but the total project timeline is usually 2-4 weeks when you factor in permits, inspections, and any necessary drywall repairs.

The actual rewiring timeline depends heavily on your home's size, layout, and accessibility. A 1,200 sq ft Craftsman bungalow in Kitsilano with an accessible basement and attic might be completed in 3-4 days, while a 2,000 sq ft Vancouver Special with limited access could take a full week. Two-storey character homes built in the 1920s-1940s often fall somewhere in the middle at 4-6 days of electrical work.

Access is the biggest factor affecting timeline in Vancouver's older homes. Many East Vancouver and Commercial Drive character houses have knob-and-tube running through finished walls and ceilings, requiring strategic opening of drywall to fish new cables. Homes with unfinished basements and accessible attics are much faster to rewire. Your electrician will need to install a new electrical panel (usually upgrading from 60-100 amp to 200 amp service), run new circuits throughout the house, and ensure everything meets current BCBC 2024 electrical code requirements.

In British Columbia, all electrical work must be performed by a licensed electrician registered with Technical Safety BC (TSBC) — not ESA like in Ontario. The electrician will pull the electrical permit and arrange for TSBC inspections at rough-in and final stages. Permit approval typically adds 1-2 weeks to your timeline, and you'll need to coordinate the rough-in inspection before any walls are closed up.

Expect some drywall and paint touch-ups after the electrical work is complete. Most electricians work with drywall contractors to minimize wall damage, but some patching is inevitable. Budget an extra 3-5 days for drywall repairs and painting to bring everything back to finished condition.

Professional guidance is essential here — knob-and-tube replacement isn't a DIY project. Insurance companies often require full replacement before renewing policies on homes with knob-and-tube wiring, and it's a safety priority given the fire risks of 80-100 year old wiring systems.

Your next step is getting quotes from licensed electricians who specialize in heritage home rewiring. They'll assess your specific home's layout and provide a realistic timeline based on accessibility and scope. Most Vancouver electricians are booking 2-4 weeks out for major rewiring projects, so plan accordingly if you're facing an insurance deadline.
