If your home went up or was rewired between the mid-1960s and the late 1970s, there is a good chance it runs on aluminum branch wiring. It was common across Winnipeg and the suburbs that were growing in that era, and it was code-legal at the time. The problem is not the aluminum itself. It is what happens at the connections, where aluminum expands and contracts more than copper, works itself loose over the years, and can overheat at outlets, switches, and panel terminations. That is where the fire risk lives, and it is why insurers ask about it.
We assess, repair, and replace aluminum wiring on homes across Winnipeg and the Interlake. The right fix depends on the condition of the wiring and how it was installed, and a big part of our job is telling you honestly which one your home actually needs rather than selling you the most expensive option.
The first step is finding out what you have and what condition it is in. Not every aluminum system needs a full rewire. In many homes the wiring itself is sound and the risk is concentrated at the connections, which can be fixed without replacing the runs. We open and inspect a representative sample of devices and the panel, look for the signs of overheating like discoloured terminals or warm cover plates, and tell you what the wiring needs.
There are two honest paths, and we walk you through which fits your home. Remediation keeps the existing aluminum runs and fixes the connections, where the danger is. We pigtail a short length of copper onto the aluminum at each device and panel termination using connectors approved for the job, so every outlet, switch, and breaker lands on copper. A full replacement means running new grounded copper throughout, and it makes sense when the wiring is damaged, has been worked on badly over the years, or when a renovation already has the walls open.

Aluminum work also pairs naturally with an electrical panel upgrade, since homes of this era are often on a service that is now undersized for how they are used.
Aluminum branch wiring is one of the most common reasons a Manitoba home gets flagged at a policy renewal or a sale. Many insurers will not write a policy until it has been inspected and remediated by a licensed electrician, and others charge a higher premium for it. We do the work to the current Manitoba electrical code and provide the permit and inspection records your insurer or a future buyer will ask for. The original knob and tube found in older Winnipeg homes is a separate issue with its own fix.
Aluminum work is exactly the kind of job where an honest assessment matters, because the gap between fixing the connections and rewiring the whole house is large, and not every home needs the bigger job. We have worked on these homes across Winnipeg and Selkirk since 2016.
The clearest sign is in the panel or at the cable jacket, where aluminum is a dull silver and is usually stamped aluminum or AL on the sheathing. Warm outlet covers, flickering lights, or discoloured switches can also point to loose aluminum connections. If your home was built between about 1965 and 1978, it is worth having checked.
Usually not. In many homes the wiring is sound and only the connections need fixing, which we do by pigtailing copper at each device with approved connectors. A full rewire is reserved for wiring that is damaged or for homes already opened up for a renovation. We tell you which your home needs after we look.
In most cases, yes. Properly remediated or replaced aluminum wiring, permitted and inspected, is what insurers are looking for, and we provide the documentation to prove it was done right. Confirm the specifics with your insurer, since requirements vary between companies.
