Aluminum, knob-and-tube and ungrounded wiring fixed in Edmonton

Older Edmonton homes rewired or remediated to the current code, with the documentation your insurer, lender or buyer is asking for.

The right fix for the wiring your house actually has

Houses built in Edmonton before the mid-1970s often have one of three things behind the walls: aluminum branch wiring (roughly 1965 to 1976), knob-and-tube (pre-1950s) or two-wire ungrounded cable. Each has a correct, code-accepted remedy, and none of them is ‘rip out every wall’. MNR Electric inspects first, tells you what you have, and prices the remediation that satisfies the Canadian Electrical Code and your insurer, from approved connectors on aluminum to a full rewire where that is the honest answer.

Rewiring and remediation

Aluminum wiring remediation

CSA-approved AlumiConn or COPALUM-style connections at every device and junction, or replacement where runs are damaged. Insurer-ready report included.

Knob-and-tube replacement

Live knob-and-tube removed and replaced with modern cable, room by room or whole house, with minimal drywall disturbance.

Ungrounded circuits

Two-prong circuits grounded, or protected with GFCI as the code allows, so outlets are safe and labelled correctly.

Renovation wiring

Kitchens, bathrooms, basements and additions wired to today's code: dedicated circuits, AFCI and GFCI, lighting layouts.

Basement suites

Secondary suite wiring to City of Edmonton requirements, including interconnected smoke alarms and a separate panel where needed.

Documentation

Permit, inspection record and a letter describing the work, for insurers, lenders and real estate closings.

Rewiring questions

Usually not. Most insurers accept remediation of the connections with CSA-approved connectors by a licensed electrician, with a permit and a letter. A full rewire is only recommended when the cable itself is damaged or the house is being opened up anyway. We inspect first and tell you which applies.

Existing knob-and-tube is not illegal, but it cannot be extended, it must not be buried in insulation, and most insurers will not cover it or will charge heavily for it. Replacement is the usual answer and it is less disruptive than people expect.

Far less than you might think. Our electricians fish new cable through finished walls and ceilings and keep openings small and in places that are easy to patch. We tell you where before we start.

Yes, always. Rewiring is permitted work under the Safety Codes Act. We pull the permit under our master electrician, book the City inspection and give you the passed record.
