Aluminum wiring · Greater Montreal
Aluminum wiring in Montreal homes
Many Montreal homes wired between the mid 1960s and the mid 1970s carry aluminum wiring. It is a known problem with known corrections. We assess it, explain your options plainly, and correct it to code, with documentation your insurer can read.

What the work includes
Correct the connections or rewire in copper
The assessment comes first. Every project starts by finding out what is actually behind your walls and inside your panel. From there, two honest paths: correct every connection with certified connectors, or replace the aluminum with copper. We price both and tell you which one your house actually needs.
Aluminum wiring assessment
Accessible connections checked at outlets, switches, fixtures and the panel. You get a written picture of what is there and what state it is in.
Connection correction (pigtailing)
Each aluminum end is joined to a copper conductor with a connector certified for aluminum to copper joints. Devices that stay on aluminum are replaced with CO/ALR rated ones.
Full copper rewiring
The definitive fix, planned circuit by circuit to limit opened walls. Replacing aluminum wiring with copper makes the question go away for good.
Panel and fuse box replacement
Insurers flag fuse boxes in the same letter as aluminum wiring. If yours is due, both are handled as one project.
Panel upgrades →Grounding verification
Missing grounding is the third item Quebec insurers refuse. We verify ground protection circuits and correct what is absent.
Documentation for your insurer
Work performed under RBQ licence 8351-6120-43, with an invoice that describes the correction. Something concrete for your insurer, your broker or your buyer.
The physics, plainly
Why aluminum wiring fails at the connections
In the late 1960s the price of copper climbed and builders across Canada switched to aluminum for branch wiring. Montreal grew fast in those years, so the island and its suburbs are full of homes that still carry it. The wire itself, sized correctly, conducts safely.
The weak point is every place the wire ends. Aluminum expands and contracts with heat more than copper, so each cycle works screw terminals a little looser. It oxidizes, and unlike copper oxide, aluminum oxide barely conducts. Aluminum is also softer: it slowly deforms under the pressure of a screw and the clamp loses its grip. A loose, oxidized connection resists current, resistance makes heat, and heat loosens it further.
That is why correction happens at the connections, not in the middle of walls, and why a correct assessment matters more than a dramatic one. It is the same discipline we bring to everything we do across Greater Montreal.
Signs a connection is failing now
- Breakers that trip repeatedly
- Lights that flicker or dim
- Sizzling or buzzing sounds
- A burning smell
- Outlets discoloured or hot to the touch
- Sparking outlets
A burning smell right now: cut power at the panel and call (514) 909-3773. The emergency line is answered 24/7. One sign on its own can have other causes: our electrical repairs page covers the usual suspects.
Why it matters
Faulty wiring is the number one cause of electrical fires. In Montreal, 22% of residential fires are attributed to electrical malfunction (source: SPQ). Insurers pay attention to aluminum wiring for a reason. So do we.
Two ways this starts
Buying a house, or renewing your insurance
Almost every aluminum wiring call begins with one of these letters. Both have a clean way through.
Buying a house with aluminum wiring
The pre-purchase inspection flags aluminum wiring and the deal suddenly feels fragile. It does not have to be. We assess the wiring and give you a firm correction price you can bring to the negotiation. Sellers can do the reverse: correct first, and hand buyers documentation instead of a discount. Brokers call us for exactly this.
Call (514) 909-3773Home insurance and aluminum wiring
Quebec insurers refuse renewals and new policies when aluminum wiring, fuse boxes or missing grounding are present. If the letter has arrived, ask your insurer exactly what they require, then call. We correct to that requirement and document the work under RBQ licence 8351-6120-43.

Straight answers
Aluminum wiring questions
How do I know if my home has aluminum wiring?
Start with the age: homes built or renovated between the mid 1960s and the mid 1970s are the usual candidates. At the panel, cable jackets marked AL, ALUM or ALUMINUM and silver coloured conductors are the giveaway, copper looks reddish. Do not open outlets to check, that is live equipment. An assessment answers the question safely and in writing.
Do I have to replace all the wiring with copper?
Not always. There are two recognized corrections: a full copper rewire, or correcting every connection with certified aluminum to copper connectors and CO/ALR rated devices. Which one makes sense depends on the state of the wiring, your insurer's requirements and your plans for the house. We price both and tell you plainly which one we would choose.
Will my insurer accept a connection correction, or do they want copper?
It varies by company. Quebec insurers have refused new policies and renewals over aluminum wiring, fuse boxes and missing grounding, but what each one accepts as a correction differs. Ask your insurer in writing what they require before choosing the scope. Whatever they answer, the work is done under RBQ licence 8351-6120-43 and documented so you have something to show them.
We are buying a house with aluminum wiring. Should we walk away?
No. It is a known condition with known corrections. Get the wiring assessed before you finalize the price, so the correction is a number on the table instead of a fear. Brokers and inspectors flag aluminum wiring, which is their job. Ours is telling you exactly what it takes to make it right.
