Old Wiring in Jacksonville Homes: Aluminum, Knob-and-Tube & When to Worry

<h2>Does Your Jacksonville Home Have Dangerous Old Wiring?</h2> <p>If your Jacksonville home was built before 1980, there's a good chance you're living with outdated — and potentially dangerous — electrical wiring. From the historic homes of Riverside to 1970s ranch houses in Arlington, Northeast Florida is full of properties with wiring that wasn't designed for modern electrical loads.</p>

<p>Here's how to identify old wiring types, understand the risks, and know when it's time to call a professional.</p>
