Aluminum Wiring in Florida Homes: What Buyers Must Know

If you are buying or selling a home in Orlando or Central Florida, aluminum wiring is one of those hidden issues that can derail a deal — or worse, create a genuine fire hazard. Homes built between 1965 and 1973 frequently used aluminum wiring instead of copper, and many of those properties are still on the market today throughout Orange, Osceola, Lake, and Seminole counties. Understanding what aluminum wiring means for your inspection and your insurance is critical before you close.

Why Aluminum Wiring Is a Safety Concern in Florida Homes

Aluminum wiring was widely used during the mid-1960s and early 1970s because copper prices spiked and aluminum was a cheaper alternative. The problem is that aluminum expands and contracts more than copper when electricity flows through it. Over time, this movement loosens connections at outlets, switches, and panel terminals — creating heat buildup and increasing the risk of arcing and house fires.

The U.S. Consumer Product Safety Commission found that homes with aluminum wiring are 55 times more likely to have fire hazard conditions than homes with copper wiring. In Florida's heat and humidity, those expansion cycles happen more aggressively, which makes the risk even more real for homeowners in the Orlando area.

How to Identify Aluminum Wiring During a Home Inspection

A trained home inspector can identify aluminum wiring in several ways:

• Panel markings: Aluminum branch circuit wiring often has "AL" marked on the wire sheathing inside the electrical panel.
• Wire color: Aluminum wiring is silver-colored rather than the copper color of standard wiring.
• Panel and outlet labeling: Older panels and devices rated only for copper ("CU") connections are a red flag when aluminum is present.
• Warm outlets or switch plates: Heat at connection points is a warning sign that expansion and arcing may already be occurring.

At Simplispect, our inspectors are trained to look for aluminum wiring signs throughout the electrical system — not just at the panel — so buyers know exactly what they are buying.

What Happens If Aluminum Wiring Is Found?

Finding aluminum wiring during a home inspection in Central Florida is not necessarily a deal-breaker, but it does require action. There are three common remediation options:

• Complete rewire: Replacing all aluminum branch circuit wiring with copper is the most thorough fix. It is also the most expensive, often ranging from $8,000 to $20,000 or more depending on the size of the home.
• Pigtailing with CO/ALR devices: A licensed electrician can install approved copper pigtail connections at every outlet, switch, and junction box. This is a widely accepted, cost-effective solution when done properly with CO/ALR-rated devices.
• AlumiConn connectors: These UL-listed connectors join aluminum and copper wires at each connection point and are approved by the CPSC as a safe repair method.

Any remediation should be completed by a licensed Florida electrician and re-inspected for proper execution.

Aluminum Wiring and Florida Home Insurance

Here is something many buyers in the Orlando area discover only after their offer is accepted: many Florida insurance carriers will not write a new policy on a home with aluminum branch circuit wiring, or they will charge significantly higher premiums. Citizens Property Insurance and several private carriers require proof of remediation before insuring these homes.

This matters during the home buying process because your lender will require homeowners insurance before funding the loan. If the wiring is not disclosed or addressed, you could face a last-minute closing delay or be left scrambling for a specialty carrier willing to insure an unremediated home.

The good news: if a seller remediates the wiring before closing — or if the purchase price reflects the repair cost — the home can be a great value. The key is knowing about it upfront. That is exactly why a thorough home inspection in Central Florida is non-negotiable for any property built before 1975.
