Aluminum Wiring Repair & Remediation in Florida

Homes built between 1965 and the mid-1970s often have single-strand aluminum branch wiring. The CPSC found these homes are 55 times more likely than copper-wired homes to reach fire hazard conditions at connections.

CPSC Safety Finding

The U.S. Consumer Product Safety Commission found that pre-1972 aluminum-wired homes are 55 times more likely than copper-wired homes to reach "fire hazard conditions" at connections. Aluminum wiring is the leading electrical cause of house fires in homes of this era.

Why Aluminum Wiring Is a Problem

During the mid-1960s, copper prices spiked and builders switched to aluminum for branch circuit wiring (the wiring that runs from your panel to outlets, switches, and fixtures). Aluminum was cheaper and conducted electricity well, but it has physical properties that make it problematic at connections.

The core problem is thermal expansion and contraction. Aluminum expands and contracts more than copper when current flows through it. Over years of heating and cooling cycles, this causes connections to loosen at every device in your home. Loose connections arc, and arcing generates intense heat that can ignite insulation, wood framing, and other combustibles, often inside walls where it goes undetected.

Aluminum also oxidizes more readily than copper. Aluminum oxide is a poor conductor, so oxidized connections have higher resistance, which generates even more heat.

The CPSC estimates that approximately 2 million homes in the United States still have single-strand aluminum branch wiring. Many are in Florida, where the building boom of the 1960s and 1970s coincided exactly with the aluminum wiring era.

Does Your Home Have Aluminum Wiring?

Single-strand aluminum branch wiring was used primarily from 1965 to the mid-1970s. If your home was built during this period, there's a significant chance it has aluminum wiring.

  • Wire insulation in your panel or attic is silver-colored (copper is orange/red)
  • Wire jacket is labeled 'AL' or 'ALUMINUM'
  • Home was built between 1965 and 1975
  • Outlets or switches feel warm to the touch
  • Lights flicker or dim intermittently
  • Burning smell near outlets or switches
  • Outlets or switches are discolored or have scorch marks

Important: Aluminum wiring in the service entrance (the large wires coming from the utility to your meter and panel) is normal and not a concern. The problem is single-strand aluminum branch circuit wiring. the smaller wires running to outlets, switches, and fixtures.

CPSC-Accepted Remediation Methods

The CPSC recognizes two methods for aluminum wiring remediation. Both involve adding a short copper "pigtail" at each connection point so that the final connection to every device is copper-to-copper. We offer both methods and will recommend the right one for your home and insurance carrier.

COPALUM

CPSC Gold Standard

A special crimping tool permanently joins a short copper pigtail to each aluminum wire end, creating a gas-tight connection. Accepted by all Florida insurance carriers.

Permanent, no maintenance required
Accepted by all Florida carriers
Gas-tight crimp eliminates oxidation
CPSC recommended method
Requires specialized AMP COPALUM tool
Slightly higher cost than AlumiConn

AlumiConn

CPSC Accepted

A multi-port connector filled with anti-oxidant compound joins aluminum and copper wires at each device location. Faster and less expensive than COPALUM.

CPSC accepted method
Accepted by most Florida carriers
Faster installation
Lower cost
Requires anti-oxidant compound maintenance over time
Not accepted by all carriers (verify with yours)

Note: Complete rewiring (replacing all aluminum with copper) is also an option but is significantly more expensive and disruptive. COPALUM and AlumiConn are the practical solutions for most homeowners.

Aluminum Wiring & Florida Homeowners Insurance

Most Florida insurance carriers will not write or renew a policy on a home with unremediated single-strand aluminum branch wiring. It is one of the most common reasons for policy non-renewal in older Florida homes.

After COPALUM or AlumiConn remediation, most carriers will accept the home. We provide a signed letter documenting the completed work, the method used, and the scope of remediation. Your insurance agent can submit this to bind or reinstate your policy.

If you also have a problematic panel brand (Federal Pacific, Zinsco, Challenger, or Pushmatic), we recommend addressing both at the same time. We coordinate the utility disconnect, permits, and inspection for both jobs together, which is more efficient and cost-effective.

Frequently Asked Questions

Single-strand aluminum wiring expands and contracts more than copper when current flows through it. Over years, this causes connections to loosen at outlets, switches, and fixtures. Loose connections arc and generate heat, which can ignite surrounding materials. The CPSC found that pre-1972 aluminum-wired homes are 55 times more likely than copper-wired homes to reach 'fire hazard conditions' at connections.
Homes built between 1965 and the mid-1970s are most likely to have single-strand aluminum branch wiring. You can check by looking at the wire insulation in your panel or attic, aluminum wiring is silver-colored (copper is orange/red). The wire jacket may also be labeled 'AL' or 'ALUMINUM'. A licensed electrician can confirm during an inspection.
COPALUM is a CPSC-accepted aluminum wiring remediation method developed by AMP Inc. (now TE Connectivity). It uses a special crimping tool to permanently join a short copper pigtail to each aluminum wire end. The crimp creates a gas-tight connection that eliminates the oxidation and loosening problems. COPALUM is the gold standard fix and is accepted by all Florida insurance carriers.
AlumiConn is a CPSC-accepted alternative to COPALUM. It uses a small multi-port connector filled with anti-oxidant compound to join aluminum and copper wires at each device location. AlumiConn is faster and less expensive than COPALUM and is accepted by most Florida insurance carriers.
Standard outlets and switches are rated for copper only. You can use CO/ALR-rated devices (rated for aluminum), but this only addresses the device connections, not the connections at junction boxes, fixtures, and the panel. COPALUM or AlumiConn remediation addresses all connection points and is the only fix accepted by Florida insurance carriers.
Most Florida carriers will not write or renew a policy on a home with unremediated aluminum wiring. After COPALUM or AlumiConn remediation, most carriers will accept the home. We provide the signed documentation your agent needs.
The timeline depends on the number of circuits and devices. A typical 3-bedroom home takes 1–2 days. We provide a detailed scope of work and timeline in the written quote.
Yes, if you have both aluminum wiring and a problematic panel brand, doing both at the same time is more efficient and cost-effective. We coordinate the utility disconnect, permits, and inspection for both jobs together.
Yes. Aluminum wiring remediation is electrical work that requires a permit and inspection in Florida. We pull the permit and meet the inspector.
