Aluminum Wiring Remediation in Calgary: Safe, Code-Compliant, Insurer-Friendly

Aluminum branch wiring showed up in many Calgary homes in the late 1960s and 1970s. It isn’t illegal, and it isn’t automatically “bad.” The risk is at the connections over time: oxidation, loosened terminations, and heat. The fix is proper assessment, approved remediation methods, and clear documentation. Start with our photo-based Online Estimate or explore all Residential services.

What “safe remediation” actually means

Safe remediation brings existing aluminum circuits up to a reliable standard without shortcuts. That typically includes approved connectors (AlumiConn or COPALUM where available), device upgrades rated for the application, corrected terminations, and verification of required protection (GFCI/AFCI). We also confirm box fill, label the panel, and leave work that’s serviceable for future techs. See how we operate on Why Crew.

When remediation is right vs. rewiring

If the conductors are in good condition and access is limited, remediation at devices and terminations is often the smart move. If we find widespread heat damage, brittle insulation, or you’re planning larger upgrades, partial or full copper rewiring may be recommended. When capacity is tight, pairing remediation with a Panel Upgrade can future-proof the system for additions like EV charging.

Insurance considerations

Many insurers request inspection, remediation, or upgrades for homes with aluminum branch circuits. Crew Electrical Services documents findings and changes so you can provide a straightforward record during policy renewal. If you’re in the due-diligence stage after an electrical issue, our Troubleshooting & Repairs page explains how we isolate root causes before we remediate.

Our process (simple and predictable)

Initial assessment. We identify aluminum runs, open a sample of devices, and check terminations, box fill, and conductor condition.
Clear recommendations. You get a plain-English plan: remediation at terminations, targeted device upgrades, protection updates, and whether any areas warrant partial rewiring.
Professional remediation or upgrade. Licensed electricians complete the work using approved connectors and methods, then correct labeling and documentation.
Final testing and documentation. We test protection, verify torque, label the panel, and provide written records for your files and insurer.

FAQ: Aluminum Wiring in Calgary Homes

Is aluminum wiring dangerous?
Not by default. The risk is at the connections. Proper remediation at devices and terminations significantly reduces overheating potential.

How do I know if my home has aluminum wiring?
Look for “AL” or “ALUMINUM” on cable jackets in unfinished areas, or “AL” on conductor insulation. If you’re unsure, we can confirm during an Online Estimate review and site visit.

What are AlumiConn and COPALUM?
Both are listed, approved methods for joining aluminum to copper safely. AlumiConn uses a multi-port set-screw connector; COPALUM is a cold-weld crimp installed with a specific tool set. We specify based on availability and site conditions.

Can I just replace the outlets and be done?
Replacing devices without addressing aluminum terminations isn’t a solution. Devices must be compatible and connected with approved methods. When in doubt, book Troubleshooting & Repairs so we can verify the cause.

Will remediation stop warm outlets and flicker?
If heat or flicker came from loose aluminum terminations or incompatible devices, remediation typically fixes it. We verify with testing before we leave.

Do I need GFCI or AFCI with aluminum wiring?
Protection requirements depend on location and current code. We confirm what applies during the assessment and test that protection functions correctly after remediation.

Will I need to open walls?
Usually, no. Most remediation happens at accessible devices and the panel. If we find damaged conductors inside a wall, we’ll explain options, which may include targeted rewiring.

How long does remediation take?
Many homes are one to two working days, depending on size and device count. Larger homes or added upgrades take longer. You’ll have a schedule up front.

Is full copper rewiring better for resale?
Buyers and insurers like clean documentation either way. If your aluminum is sound and remediated correctly, that’s often enough. During renovations, partial or full copper rewiring can make sense; we’ll outline both paths.

What will you leave me with when it’s done?
A labeled panel, tested protection, upgraded devices where needed, corrected terminations, and written documentation of what changed.
