What You're Actually Dealing With Here

Between 1965 and the mid-1970s, builders across North Carolina installed aluminum wiring in roughly two million homes because copper prices shot through the roof. It made sense at the time. But aluminum behaves differently than copper—it expands and contracts more when electricity flows through it, which loosens connections at outlets, switches, and junction boxes over the years.

Those loose connections create resistance. Resistance creates heat. Heat damages insulation, melts wire jackets, and in worst-case scenarios, starts fires inside your walls. The U.S. Consumer Product Safety Commission found that homes with aluminum wiring are 55 times more likely to reach fire hazard conditions than homes wired with copper.

If you’re buying a home built during that era, or you already own one and just found out it has aluminum wiring, you’re probably wondering what to do next. The good news is that you don’t necessarily need to rewire your entire house. There are proven, permanent remediation methods that eliminate the hazard at every connection point—and that’s exactly what we specialize in.

Why Aluminum Wiring Becomes Dangerous Over Time

Aluminum isn’t inherently unsafe—utility companies still use it for power transmission lines. The problem is what happens at the connections inside your home, and it’s a combination of physics and chemistry working against you.

When electricity flows through aluminum wire, the wire heats up and expands. When the load drops, it cools and contracts. Copper does this too, but aluminum’s expansion rate is significantly higher. Over thousands of heating and cooling cycles—which happen every single day in your home—the wire literally creeps out from under the terminal screws at your outlets and switches. That creates gaps, and gaps create resistance.

Then there’s oxidation. Aluminum forms an oxide layer when exposed to air, and unlike copper oxide (which still conducts electricity), aluminum oxide is an insulator. It increases resistance even more. More resistance means more heat. More heat means faster deterioration of the connection, more oxidation, looser screws, and the cycle accelerates.

Add in the fact that aluminum is softer than copper and gets nicked more easily during installation, and you’ve got a wiring system that degrades faster and fails more dramatically than anyone expected back in the 1960s. The connections don’t just stop working they overheat to the point where they can ignite the materials around them. That’s why the Consumer Product Safety Commission and insurance companies take this so seriously.

What's Included in a Proper Aluminum Wiring Remediation

A real remediation isn’t just replacing a few outlets with CO/ALR-rated devices and calling it done. That’s a band-aid, and it’s not what the Consumer Product Safety Commission recommends for a permanent fix.

The right approach involves pigtailing every single aluminum wire connection in your home—outlets, switches, light fixtures, junction boxes, appliances, everything. We attach a short section of copper wire to the end of each aluminum wire using specialized connectors (COPALUM or AlumiConn) that are specifically engineered for aluminum-to-copper transitions. The copper pigtail then connects to your device, which eliminates the problem at the exact point where failures happen.

COPALUM connectors use a special crimping system that creates what’s essentially a cold weld between the aluminum and copper. It’s the gold standard, but it requires specialized tools and training. AlumiConn connectors are lug-style connectors that any licensed electrician can install with the proper torque screwdriver—they’re the next best alternative and what we use most often for residential work in the Triangle area.

ESP Electrical Service Providers also inspects your electrical panel for mixed aluminum and copper connections, double-tapped lugs, burnt terminals, and other issues that commonly show up in homes from this era. If your panel needs work, we address it. If your circuits would benefit from arc fault protection, we recommend it. The goal is a complete, permanent solution that you won’t have to worry about again.

FAQ

Frequently Asked Questions

How do I know if my home has aluminum wiring?

If your home was built or had electrical work done between 1965 and 1978, there’s a good chance you have aluminum wiring somewhere in the system. The easiest way to check is to look at the cables in your attic, basement, or electrical panel where the wire jacket is visible. Aluminum wiring is usually marked with “AL” or “ALUMINUM” printed on the plastic sheathing every few feet. The wire itself has a dull silver color, different from the orange-copper color of copper wire. You can also check outlets and switches—if they’re marked “CO/ALR” or “AL/CU,” that’s a sign they were installed specifically for aluminum wiring. But don’t remove cover plates or touch any wires yourself. If you’re not certain, have a licensed electrician inspect your panel and accessible wiring. We do these assessments regularly for homeowners in Alamance, Durham, Chatham, and Orange Counties, and we can tell you definitively what you’re dealing with and what needs to be done about it.

Do I really need to fix aluminum wiring or can I just leave it alone?

Technically, aluminum wiring that’s been properly maintained and hasn’t shown signs of failure can continue operating. But here’s the reality: the deterioration is cumulative and often happens inside walls where you can’t see it until there’s smoke or sparks. The Consumer Product Safety Commission found that homes with pre-1972 aluminum wiring are 55 times more likely to have connections reach fire hazard conditions compared to copper-wired homes. That’s not a small difference. Beyond the safety issue, you’ll likely run into problems with homeowners insurance—many carriers won’t write or renew policies on homes with aluminum wiring unless it’s been professionally remediated. If you’re selling, buyers will either demand remediation or walk away when the inspection report flags it. So while you can technically leave it alone in the short term, you’re accepting a significantly higher fire risk and you’ll eventually be forced to deal with it anyway when you sell or your insurance comes up for renewal. The smart move is to address it now with a permanent CPSC-approved solution rather than waiting for it to become an emergency or a deal-killer.

What's the difference between pigtailing and completely rewiring my house?

Pigtailing means we attach short sections of copper wire to the ends of your existing aluminum wires at every connection point—outlets, switches, light fixtures, junction boxes, everything. We use specialized connectors (COPALUM or AlumiConn) that are specifically engineered for safe aluminum-to-copper transitions. The copper pigtail then connects to your device, which eliminates the hazard where it actually occurs: at the termination points. This is a CPSC-approved permanent repair that addresses the root problem without tearing into your walls. Complete rewiring means removing all the aluminum wire and replacing it with copper throughout your entire house. That’s the most comprehensive solution, but it’s also significantly more expensive and disruptive—you’re looking at opening walls, ceilings, and potentially dealing with drywall repair and repainting throughout your home. For most homeowners, proper pigtailing with approved connectors gives you the same safety outcome at a fraction of the cost and disruption. We can do either one depending on your situation, but pigtailing is usually the smarter choice unless you’re already doing a major renovation that involves opening walls anyway.

Will fixing my aluminum wiring help me get homeowners insurance?

In most cases, yes. Many insurance companies either deny coverage outright for homes with aluminum wiring or charge significantly higher premiums because of the documented fire risk. Some will write a policy but require you to have the wiring remediated within a certain timeframe, and they’ll want documentation from a licensed electrician confirming the work was done using approved methods. When we complete an aluminum wiring remediation, we provide detailed documentation that shows every connection was addressed using CPSC-approved COPALUM or AlumiConn connectors. That’s usually enough to satisfy insurance underwriters, though you should check with your specific carrier about their requirements before starting the work. Some insurers want to see CO/ALR-rated devices at every outlet and switch. Others are fine with pigtailing using approved connectors. A few still won’t cover homes with any aluminum wiring regardless of remediation, in which case you’ll need to shop for a different carrier or consider complete rewiring. But for the vast majority of homeowners we work with in the Triangle area, proper remediation opens the door to standard insurance coverage at normal rates.

How much does aluminum wiring remediation typically cost?

The honest answer is it depends on the size of your home and how many connection points need to be addressed. A typical single-family home might have anywhere from 30 to 100+ connection points depending on square footage and how the circuits were originally run. Pigtailing with AlumiConn connectors generally runs significantly less than complete rewiring—often a fraction of the cost—because we’re not tearing into walls or replacing hundreds of feet of cable. Complete rewiring can run into tens of thousands of dollars for a full house, while proper pigtailing usually costs considerably less and can be completed in one to three days depending on the scope. We use flat-rate pricing, so you’ll know exactly what you’re paying before we start any work. No hourly billing, no surprise charges when the job takes longer than estimated. The best approach is to have us come out and assess your specific situation. We’ll inspect your panel, check accessible wiring, and give you a detailed quote that covers everything that needs to be done to make your system safe and satisfy insurance requirements. That initial assessment gives you the real numbers you need to make an informed decision.

Can I just replace outlets and switches with CO/ALR-rated devices instead of pigtailing?

CO/ALR-rated outlets and switches are designed to work with aluminum wire, and they’re better than standard devices that were never meant for aluminum connections. But here’s the problem: replacing devices only addresses the outlets and switches. It doesn’t fix the connections at light fixtures, junction boxes, appliances, or inside your electrical panel—and those connections fail just as often as the ones at your outlets. The Consumer Product Safety Commission doesn’t consider CO/ALR devices alone to be a complete or permanent repair for exactly that reason. They’re a partial solution at best. If you want a real fix that eliminates the hazard throughout your entire electrical system, you need pigtailing with approved connectors at every aluminum wire termination, not just the visible outlets. That’s what we do, and that’s what actually solves the problem long-term. CO/ALR devices can be part of the solution in certain situations, but they’re not a substitute for comprehensive remediation using COPALUM or AlumiConn connectors at every connection point in your home.
