Aluminum Wiring: Why It’s a Hazard and How SureTek Electric Can Help
Aluminum was commonly used in homes built between 1965 and 1978, but it has since been recognized as a significant fire hazard. While it was initially seen as a cost-effective alternative to copper, aluminum wiring poses serious safety risks due to its tendency to overheat, loosen over time, and cause electrical fires if not properly maintained.
At SureTek Electric, we specialize in aluminum wiring inspections, repairs, and full replacements, ensuring your home meets modern electrical safety standards. If your home contains aluminum wiring, taking action now can prevent electrical failures, insurance complications, and potential fire hazards.

Why Aluminum Wiring is a Serious Safety Concern
Homes with aluminum are at a much higher risk of electrical fires than those with copper wiring. This is due to aluminum’s physical properties, which make it more prone to overheating, corrosion, and loose connections over time.
Overheating and Electrical Fire Risks
Aluminum has higher electrical resistance than copper, meaning it generates more heat when electricity flows through it. This heat can cause wiring connections to loosen, degrade insulation, and spark electrical fires.
Common warning signs of overheating include:
- Discolored or scorched outlets and switch plates
- Frequent flickering lights or circuit breaker trips
- A burning smell near electrical outlets or switches
- Outlets that feel warm or hot to the touch
If you notice any of these signs, get an inspection immediately.
Loose Connections and Oxidation
Aluminum expands and contracts with temperature changes, which can loosen wiring over time. Loose wires may spark, arc, or fail entirely.
Aluminum also oxidizes when exposed to air. This increases resistance and heat at connection points, further raising fire risk.
Wiring Repair: What Are Your Options?
If your home has aluminum wiring, you don’t necessarily need a full rewiring. SureTek Electric offers code-compliant solutions to reduce fire risks and keep your home safe.
Pig-Tailing with Copper Connectors
This process attaches short copper wires to aluminum using AL/CU-rated connectors. It improves conductivity and safety — but must be installed by a licensed electrician. The wrong connectors can make things worse.
Replacing Outlets and Switches
Many homes still have standard outlets not rated for aluminum. We replace these with CO/ALR-rated devices to ensure a solid, safe connection between aluminum wires and your outlets.
Full Aluminum Wiring Replacement
The most permanent and safest solution. Rewiring your home with copper eliminates fire risks, improves insurance eligibility, and raises resale value — especially if you’re planning major renovations.
How SureTek Electric Can Help
We specialize in complete aluminum wiring repair and replacement. Our process includes:
- Thorough aluminum inspections — Checking for overheating, loose connections, and arcing

How Much Does Wiring Repair Cost?
Cost depends on home size, wire condition, and chosen solution. Here are rough estimates:
- Pig-tailing repairs: $50–$60 per outlet/switch
- CO/ALR outlet replacements: $80–$100 per device
- Full rewiring: $8,000–$15,000 depending on home size
Some insurance companies may require upgrades before issuing or renewing coverage.
