Aluminum Wiring
Aluminum wiring was at one point widely accepted as safe for use, but while it isn't necessarily dangerous, it certainly can be. Not only is there a potential for a safety hazard, but insurance companies often won't write a policy for homes with aluminum wiring. On top of that, aluminum wiring is one of the most inefficient forms of wiring that you can have.

Request ServiceWhat Makes Aluminum Wiring Unsafe?
- While aluminum wiring itself is not unsafe, aluminum has a tendency to oxidize very quickly. Because of that, it can start to rust and deteriorate in as little as one day. That deterioration, in turn, leads to overheating, which can lead to a house fire.
- Aluminum wiring is also softer and more malleable than copper wiring, which makes it more susceptible to damage.
- As aluminum wiring heats up, it expands. This thermal expansion means that the wiring can change shape at the terminal screws, which can cause it to come loose and/or disconnect.
In the 60s and 70s, aluminum wiring was very widely used. However, by the late 70s, many homes were already making the transition to copper. Most likely, if there's aluminum wiring in your home, you need to have at least parts of your wiring replaced. Our Baton Rouge electricians can inspect your home's wiring and help ensure that it's as safe and effective and possible.

Aluminum Wiring Inspections
Even if you have aluminum wiring in your home, you don't necessarily need to have it completely replaced. Our electricians can inspect your Baton Rouge home's electrical system and its wiring to help you determine whether you need any, all, or part of it replaced. Aluminum wiring fails at connection points more frequently than copper wiring does, but it is mostly safe for distribution, even in newer homes.
Aluminum wiring isn't a major safety hazard until it's used for branch circuit wiring. Branch circuit wires are the wires that feed into your switches, plugs, and lighting fixtures. Aluminum wiring is still commonly used for larger feeders that provide energy to things like air conditioners. Our electrical safety inspection will help you determine whether your aluminum wiring is problematic.
Frequently Asked Aluminum Wiring Questions
Aluminum wiring itself isn't automatically dangerous, but it can become a serious fire risk over time if it wasn't installed correctly or has aged poorly. The main issue is that aluminum expands and contracts more than copper, which can loosen connections and create heat buildup. A licensed electrician can inspect your system, identify any hazards, and recommend safe corrective solutions, such as rewiring or approved repair methods.
Most homes with aluminum wiring were built or wired during the 1960s and 1970s. You might notice "AL" markings on the cable jacket or see silver-colored wiring instead of copper when looking at outlets or panels. That said, you shouldn't rely on visual checks alone-professional testing is the safest way to confirm your wiring type and condition without risking damage or exposure to live circuits.
No-this is not a safe DIY project. Replacing or retrofitting aluminum wiring involves complex electrical load calculations, code compliance, and fire-safety considerations. Mistakes can lead to overheated connections, electrical fires, or failed inspections. A licensed electrician ensures proper transition methods, such as approved connectors or full rewiring where necessary, keeping your home compliant and safe.
Warm outlets, flickering lights, or discoloration around switches are common warning signs of failing aluminum wiring connections. These symptoms usually indicate loose terminations or oxidation buildup, both of which increase resistance and heat. A professional electrician can diagnose the exact cause and repair or replace affected circuits before they become a serious safety hazard.
You typically have a few safe options: approved repair methods (such as COPALUM or AlumiConn connectors, where applicable), targeted circuit replacement, or full home rewiring, depending on the system's condition and age. A qualified electrician will evaluate your home and recommend the most cost-effective and safest long-term solution rather than a temporary fix.
Aluminum wiring issues aren't just minor electrical repairs-they involve fire safety risks and strict electrical code requirements. Professional electricians have the tools, training, and certification to safely handle aluminum wiring systems and ensure long-term reliability. DIY attempts often miss hidden connection failures that can lead to serious hazards later, making professional service the only truly safe option.
