How much for a knob-and-tube insurance compliance fix in NB?

Knob-and-tube wiring insurance compliance work in New Brunswick typically runs $3,000–$8,000+ for a full remediation, though costs vary significantly depending on how much of the original wiring remains active in your home.

Insurance companies in New Brunswick have become increasingly strict about knob-and-tube (K&T) wiring. Most major insurers — including Co-operators, Intact, and Aviva — will either refuse to cover homes with active K&T or charge significantly higher premiums. The key word is active: if K&T is still carrying current, it needs to go. Abandoned (disconnected) K&T is generally less of a concern, but your insurer will want documentation.

What Drives the Cost

The price range is wide because every home is different. A 1920s Fredericton home with K&T throughout every room is a very different job than a 1950s Moncton bungalow where K&T only remains in one or two circuits. Electricians will assess how many circuits are still active K&T, how accessible your walls and attic are, and whether your panel needs upgrading at the same time.

Rough cost breakdown for New Brunswick:

• Per-circuit K&T removal and replacement: $400–$800 per circuit
• Partial remediation (a few circuits): $2,000–$5,000
• Whole-home rewire (1,500 sq ft): $8,000–$15,000
• Panel upgrade (often required alongside rewiring): add $2,000–$3,500

One important NB-specific issue: K&T wiring covered by insulation is a serious fire hazard. K&T is designed to dissipate heat through open air. When blown-in insulation was added to older NB homes (very common in energy retrofit programs), it trapped that heat. If your attic has been insulated over K&T, this is an urgent safety issue — not just an insurance paperwork problem.

TSANB Permit Requirements

Any rewiring work in New Brunswick requires a TSANB permit. Your licensed electrician pulls the permit before work begins, completes the rewiring to Canadian Electrical Code standards, and a TSANB inspector signs off with a Certificate of Compliance. That certificate is exactly what your insurance company wants to see — it's your proof the work was done properly.

Don't let anyone offer to do this work without pulling a permit. Unpermitted electrical work voids your insurance coverage and creates serious liability if there's ever a fire.

What to Do Next

Start by calling your insurance company to get their specific requirements in writing — some want full remediation, others accept partial updates with documentation. Then get 2–3 quotes from licensed NB electricians who can assess exactly how much active K&T remains and what it will take to satisfy your insurer.
