Casselberry Alert: Is Your Aluminum Wiring an Insurance Risk?
If you're searching for Electricians in Casselberry, Florida, it’s crucial to understand the hidden risks sitting inside walls built between 1965 and 1973. During the Vietnam War era, the price of copper skyrocketed, leading builders to use single-strand aluminum wiring in approximately 2 million homes across the United States. While this saved money at the time, we now know that aluminum wiring connections are 55 times more likely to reach "fire hazard conditions" than their copper counterparts.
For homeowners in neighborhoods like Secret Lake or Deer Run, this isn't just a history lesson—it's a current safety and financial concern. Spectrum Electric helps residents navigate this issue every week, turning potential hazards into safe, insurable homes. Whether you are buying a new property or have lived here for decades, knowing the status of your wiring is the first step toward protecting your family.
Why Is Aluminum Wiring Dangerous?
Aluminum wiring isn't dangerous in the middle of the wire itself, but rather at the connection points where it meets switches, outlets, and light fixtures. Because aluminum is softer and expands much more than copper when heated, it creates a unique problem called "cold creep." Over time, the cycle of heating (when you use electricity) and cooling causes the wire to wriggle loose from the screws holding it in place.
Once that connection loosens, two things happen. First, the exposed aluminum begins to oxidize. Unlike copper rust, which is conductive, aluminum oxide acts as an insulator. This increases resistance and heat. Second, the loose connection allows electricity to arc—essentially jumping through the air between the wire and the terminal. This arcing can reach temperatures exceeding 10,000 degrees Fahrenheit, easily igniting insulation, wallpaper, or wood studs inside your walls.
According to the U.S. Consumer Product Safety Commission (CPSC), homes wired with aluminum before 1972 are significantly more prone to fire hazards [1]. It’s a silent risk because the outlets usually work fine right up until they start to smolder. You typically won't know there is a problem until you smell burning plastic or see scorch marks on your outlet covers.
Will Aluminum Wiring Affect My Insurance?
Getting standard homeowners insurance with unmodified aluminum wiring is becoming nearly impossible in Seminole County. Most insurance carriers now require a 4-Point Inspection for any home over 30 years old. If the inspector ticks the box for "single-strand aluminum wiring" and does not see proof of approved remediation, the insurer will likely deny the application or issue a non-renewal notice for existing policies.
Insurers deal in risk, and the data regarding aluminum wiring fires is too high for them to ignore. Industry reports suggest that nearly 70% of standard carriers will refuse to write a new policy on a home with untreated aluminum wiring [2]. We have seen this happen frequently here in Casselberry. A family falls in love with a mid-century home near Red Bug Lake Park, gets under contract, and then scrambles at the last minute because they can't secure insurance coverage to close the loan.
If you do find a carrier willing to insure untreated aluminum, you will pay for it. Premiums can be 20% to 50% higher than a comparable home with copper wiring. You might also face a high deductible specifically for fire damage. It makes financial sense to fix the wiring not just for safety, but to unlock cheaper, standard insurance rates from major Florida carriers.
What Are the Safe Solutions for Aluminum Wiring?
You generally have three options to fix this issue: pigtailing with approved connectors, crimping with the COPALUM method, or a complete home rewire. Most Casselberry homeowners opt for pigtailing because it makes the home safe and insurable without the massive expense and mess of tearing open every wall to remove the old wire.
The Pigtailing Method
This is the most common and cost-effective solution we provide at Spectrum Electric. We don't rip out the aluminum wire. Instead, we attach a short piece of copper wire to the end of the aluminum wire using a specialized connector, usually the AlumiConn lug.
This connector keeps the aluminum and copper separate so they don't corrode against each other. It also maintains a constant spring pressure to prevent the wire from loosening when it expands and contracts. The new copper "pigtail" is what connects to your outlet or switch. This satisfies insurance requirements and removes the fire risk at the connection point.
The COPALUM Crimp Method
The COPALUM method uses a high-pressure crimping tool to cold-weld the aluminum and copper wires together into a solid metal lug. While effective, it is extremely expensive. The tool is leased only to certified electricians, and the rental costs alone drive the price up significantly. Because AlumiConn connectors are equally accepted by insurance companies and much more affordable, COPALUM has become rare in residential retrofits.
Complete Home Rewiring
This is the "Gold Standard," but it is invasive. We remove the old aluminum cables and pull brand new copper Romex through your attic and walls. While this completely modernizes your electrical system, it requires cutting drywall, repainting, and potentially moving furniture. We typically recommend this only if you are already doing a full renovation down to the studs.

How Much Does Aluminum Wiring Remediation Cost?
In Central Florida, expect to pay between $1,800 and $3,500 for a comprehensive pigtail remediation on a standard 1,500-square-foot home. A complete rewire is significantly more expensive, typically ranging from $15,000 to $25,000 depending on accessibility. Remediation usually takes our team 1-2 days, while a rewire can take a week or more.
The price variance for pigtailing depends on the number of devices in your home. We have to open every single switch, outlet, light fixture, and junction box. If your home in the Golf View/Howell Branch area has 40 devices, it costs less than a sprawling home in Deer Run with 90 devices.
When you compare the $2,500 average cost of remediation against the potential $500-$800 annual savings on insurance premiums—plus the invaluable peace of mind—the investment typically pays for itself within a few years.
A Local Case Study: Fixing a Fire Hazard in Deer Run
We recently received a call from a homeowner in the Deer Run neighborhood of Casselberry. They had lived in their 1980s home for years without issues, but they noticed the lights in the master bathroom would flicker when they ran a hair dryer. Then, they heard a faint buzzing sound coming from a hallway outlet.
When our Spectrum Electric team arrived, we removed the hallway outlet plate. The insulation on the neutral aluminum wire had completely melted away, and the plastic box behind the drywall was scorched black. It was mere moments of usage away from a structure fire.
The homeowner was terrified that they would need to tear their house apart to rewire it. Instead, we performed a whole-home remediation using AlumiConn connectors. We went through every room, ensuring each connection was secure and torque-tested to manufacturer specifications.
The result:
- The buzzing and flickering stopped immediately.
- The home passed a new 4-Point Inspection the following week.
- The homeowner successfully switched insurance carriers, saving $600 a year on their premium.
