If your home was built between the mid-1960s and late 1970s, there’s a real chance your walls are hiding a problem that most homeowners don’t discover until something goes wrong. Aluminum wiring — once a popular, cost-effective alternative to copper — is now recognized by fire safety experts and insurance carriers as a serious hazard when left unaddressed. At FHR Electric, we specialize in Aluminum Wiring Replacement Home Electrical Services for homeowners across Scottsdale, North Scottsdale, Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills. We serve all of Maricopa County, AZ, and our mission is simple: give you total confidence in what’s inside your walls — not just a patch job, but a real, lasting solution. If you’ve ever lain awake wondering whether your home is a fire waiting to happen, this page is for you.
Why Aluminum Wiring Is a Problem You Can’t Afford to Ignore
Aluminum expands and contracts more than copper with normal temperature changes. Over decades, that constant movement loosens connections at outlets, switches, and breaker terminals. Loose connections arc. Arcing starts fires. According to the documented history of aluminum wiring safety research, homes wired with aluminum are significantly more likely to experience fire-related electrical failures than copper-wired homes of the same era. That’s not fearmongering — it’s a fact that’s driven changes in building codes across the country, including right here in Arizona.
Here in the Scottsdale, AZ market, we also see a compounding problem: high heat wiring degradation. Our summers regularly push past 110°F in attic spaces where wiring runs. That extreme heat accelerates oxidation on aluminum conductors, making an already vulnerable system even more unstable. If your breaker keeps tripping, your outlets feel warm to the touch, or you’ve noticed flickering lights that no one can explain, aluminum wiring is very likely part of the story.
And if you’re thinking about selling — in a competitive Scottsdale real estate market, aluminum wiring is a red flag that will show up on any home inspection report, spook buyers, kill your deal, or force you into a last-minute price concession. Addressing it proactively is one of the smartest investments you can make in your property.
Our Aluminum Wiring Replacement Services
We don’t offer a one-size-fits-all approach, because your home isn’t one-size-fits-all. After a thorough inspection, we’ll walk you through exactly what we find and exactly what we recommend — no surprises, no inflated scope, and no work you don’t need. Here’s what our aluminum wiring replacement work typically includes:
Full Copper Rewire
The gold standard. We remove the aluminum conductors throughout your home and replace them with properly sized copper wiring, bringing your entire electrical system up to current NEC code. This is the most thorough solution and the one that delivers the highest peace of mind — and the strongest story at resale. Every circuit is tested before we close the walls, and we pull all required permits so your work is fully documented and inspected.
COPALUM Crimp Connector Remediation
In some homes — particularly larger properties where a full rewire would be significantly disruptive — a COPALUM crimp connector repair is a recognized, code-compliant remediation method. This process involves splicing a short copper pigtail onto each aluminum wire termination point using a special bi-metal crimp connector and a tool that creates a cold-weld bond. When done correctly by a trained electrician, this method is approved by the U.S. Consumer Product Safety Commission. We perform this work to the letter — every outlet, every switch, every fixture connection.
AlumiConn Connector Remediation
AlumiConn multi-port connectors are another CPSC-accepted remediation for aluminum wiring and offer a practical alternative in situations where the COPALUM tool isn’t accessible. Each connector is rated for the connection of aluminum-to-copper conductors at every termination point in the home. We treat this as a professional, whole-home solution — not a spot-fix.
Panel Inspection and Upgrade Coordination
Aluminum wiring jobs are rarely just about the wire. Many homes of that era also have aging panels with limited capacity — sometimes 100 amps or less — that can’t support modern loads: a new HVAC system, a home office, an EV charger, or a kitchen remodel. We assess your panel at the same time and can coordinate a new circuit installation or full panel upgrade so you’re not solving one problem while leaving another. If you’re wondering whether your panel is big enough for an EV charger, or thinking about a 200 amp to 400 amp upgrade, we’ll give you an honest answer backed by a real load calculation.
Arc-Fault and GFCI Protection Upgrades
During an aluminum wiring remediation, it’s the ideal time to add arc-fault circuit interrupter (AFCI) protection to your bedroom and living area circuits and GFCI protection in kitchens, bathrooms, and outdoor areas. These devices add a critical second layer of defense. We can handle your GFCI outlet installation and repairs and your arc-fault protection installation as part of the same project so you’re not scheduling multiple visits.
Permit Pulling, Inspection Coordination, and Documentation
Every aluminum wiring remediation we complete is properly permitted through the applicable city or county jurisdiction — whether that’s Scottsdale, Phoenix, Chandler, Mesa, or anywhere else in Maricopa County. We coordinate the inspection, and when the work is done, you have documentation you can hand to your insurance carrier, your real estate agent, or your buyer. If you’ve got an open or unpermitted electrical project from a previous contractor, we can address that too. Closing an open permit before a sale is a common request we handle regularly.
“We don’t just fix what we can see. We trace the problem to its source, do the work right, pull the permit, and make sure you have paper in hand when we leave. That’s how we’d want our own home treated.”

Why This Matters for Your Specific Situation
For Homeowners Concerned About Safety and Resale
The Scottsdale real estate market rewards well-maintained, properly documented homes. Buyers and their inspectors are sophisticated, and aluminum wiring is one of the first things a good inspector flags. Addressing it before you list — or simply because you want your family to be safe — is a decision that pays off both financially and emotionally. You stop wondering. You stop worrying. You flip the breaker and you know.
For Homeowners Planning a Major Remodel
A kitchen remodel, master bath renovation, or whole-home renovation is the perfect time to address aluminum wiring because the walls are already open. If you’re working with a general contractor or design-build firm, we work directly alongside your team. We understand electrical scope for remodel projects and can sequence our work so we never hold up your timeline. If your contractor doesn’t have an electrical division in-house, we’re the licensed specialists they call.
For Business Owners Who Cannot Afford Downtime
If you operate a medical or dental office, a restaurant, or any business where a power failure has immediate financial and liability consequences, aging or aluminum wiring is not a theoretical risk — it’s a ticking clock. We work with business owners throughout Maricopa County who understand that zero downtime is non-negotiable. For our dental and medical clients, we’re familiar with the specific demands of medical and dental office electrical services, including dedicated circuits, isolated ground requirements, and the power quality standards that sensitive equipment demands. For restaurant clients, we understand the stakes and the tight operating windows — our restaurant electrical services team knows how to get in, get it done, and get you back to full capacity.
