Knob & Tube Wiring Replacement in Calgary
FuseSmart Electric provides professional knob and tube (K&T) wiring replacement across Calgary and nearby communities, including Cochrane, Airdrie, and Okotoks. Outdated wiring can overheat, cause fires, and prevent insurance approval. Our licensed electricians replace old K&T wiring with safe, code-compliant copper systems, handling permits, inspections, and insurance documentation — plus 3-year warranty to back it up.
Why is Knob and Tube Wiring a Problem?
Knob and tube wiring was common in homes and businesses built before the 1950s. It uses single copper wires held by ceramic knobs and runs through ceramic tubes, often without grounding. While innovative at the time, it’s unsafe for modern electrical demands. Key issues include:
No Grounding: risk of shocks, fires, and appliance damage
Limited Capacity: frequent power issues and overheating
Aging Insulation: can rust, crack, or break, especially with moisture
Insurance Issues: replacement often required for coverage
Renovation Restrictions: permits typically require K&T removal
At FuseSmart Electric, we do not repair Knob & Tube Wiring - instead, we provide full rewiring with modern copper systems, protecting your property and ensuring compliance with city codes and insurance requirements.

-
While knob and tube wiring isn't technically illegal in Calgary, most insurers and home inspectors consider it unsafe and outdated. It lacks grounding, isn’t rated for modern electrical loads, and poses a higher fire risk, especially as insulation degrades over time. Replacing it with modern copper wiring is the safest long-term solution and is often required for insurance or renovations.
-
Knob and tube systems are most common in homes built before 1950. Check unfinished areas like basements or attics for ceramic knobs securing single wires along wood framing. Outlets without grounding (two-prong plugs) may also be a sign. The only way to know for sure is to book a licensed electrician for an inspection. FuseSmart offers free, no-pressure assessments to confirm what’s in your walls.

Replacing knob and tube wiring in Calgary typically costs $5,000 to $15,000, depending on the size of your home, accessibility of the wiring, and whether a panel upgrade is also needed. FuseSmart provides a free in-home assessment and detailed quote with no hidden fees so you know exactly what to expect before work begins.

Most full rewires take 2 to 5 days, depending on your home's layout, age, and how easily we can access the existing wiring. We’ll walk you through the full timeline during your free assessment. Our electricians work cleanly and efficiently to keep disruption to a minimum.
-
No. In Calgary, replacing knob and tube wiring must be done by a licensed electrician and typically requires a City of Calgary electrical permit (learn more). DIY rewiring is not only dangerous, it can void your insurance and fail inspections. At FuseSmart, we handle the entire process professionally and safely, from permits to inspection documentation.
-
In most cases, no. If you’re selling, renovating, or insuring your home, knob and tube wiring will often need to be fully replaced before passing inspection. Most inspectors and insurers flag it as high risk due to the lack of grounding, outdated materials, and increased fire hazard. FuseSmart provides full rewiring services and certified documentation to ensure your home is safe, compliant, and insurable.
