Aluminum wiring in a 1970s Florida home: dangerous, or just a paperwork problem?
Your insurance renewal mentioned aluminum branch wiring. Here is what that actually means, what fixes it, and why you almost never need a full rewire.

Plenty of Central Florida houses built between roughly 1965 and 1975 were wired with aluminum branch circuits. Carriers now ask about it directly, and a letter from your insurer is usually how people find out.
The wire is not the problem. The connections are.
Aluminum expands and contracts more than copper. Over decades, the screw terminals on outlets and switches loosen, and loose terminals heat up. That is the risk — and it lives at the devices, not in the walls.
What actually fixes it
Device-level remediation: listed connectors at every outlet, switch and fixture
Panel terminations checked and corrected
A written report with photos you can hand to your carrier
That approach is what most Florida carriers accept, and it costs a fraction of replacing every circuit. We quote from a device count, not your square footage.
ALUMINUM WIRING REMEDIATION
$1,800 – $9,500
Device-level remediation is the low end. Full copper branch-circuit replacement is the top of the range.
Pull one outlet cover and look. Silver-colored wire, often stamped "AL", means aluminum. Copper-colored means you can stop worrying about this one.
⚠ DON’T DIY THIS
Twisting aluminum to copper with a regular wire nut is exactly how these connections fail. The connectors have to be listed for it, and installed to spec.
Quick answers
Do I have to rewire the whole house?+
Usually no. Remediation at every device is the standard fix and most carriers accept it with documentation.
How long does remediation take?+
One to two days for most homes, and you keep power in most of the house the whole time.
