As a commercial, residential, and industrial electrical contractor, Branham by Suburban Electrical Services has seen a significant rise in questions from homeowners and business owners about insurance coverage related to outdated electrical systems. Specifically, insurance companies are increasingly requiring the replacement of older wiring and panels—such as aluminum wiring, outdated circuit panels, and knob-and-tube wiring—or risk facing higher premiums or even denied coverage.
These changes are not just a matter of insurance policy adjustments—they’re driven by safety concerns and the growing awareness of potential fire hazards associated with outdated electrical systems. If your property has one of these older electrical systems, it’s important to understand the implications for your insurance and, most importantly, your safety.
Why Are Insurance Companies Concerned About Older Wiring?
Older electrical systems—like aluminum wiring, knob-and-tube wiring, and outdated circuit panels—pose several risks. These materials and designs were once standard, but over time, they’ve been found to be far more prone to issues such as overheating, short-circuiting, and even electrical fires. Here’s a breakdown of why insurance companies are raising concerns:
-
Aluminum Wiring: A Known Fire Hazard
Aluminum wiring was widely used in homes and buildings from the 1960s to the early 1970s. However, it was later discovered that aluminum wiring could corrode over time, causing loose connections that could easily lead to overheating and fires. The wiring itself doesn’t handle heat as well as copper, and when it oxidizes, it increases the risk of sparks or fire.
One of the most significant issues with aluminum wiring that we’ve encountered in the field is its expansion and contraction during normal use. Aluminum, being softer and more malleable than copper, reacts more dramatically to temperature fluctuations. As electrical current passes through the wire, it heats up, causing the metal to expand. When the current flow stops, the wire cools and contracts. Over time, this constant cycle of expansion and contraction puts pressure on the wire and its connections at terminals or splices, which can loosen or degrade.
Loose connections in aluminum wiring increase resistance and generate additional heat. The heat can then build up at the loose connection, creating a fire hazard. This is a common issue in older homes and buildings with aluminum wiring, especially if the connections were not properly tightened or maintained. The risk is compounded when the connections are subjected to frequent thermal cycling, leading to potential arcing or short-circuiting.
Insurance companies are particularly wary of these issues, as loose, heated connections may cause fire. Many insurers now either won’t insure homes or buildings with aluminum wiring without a full rewire, or will charge significantly higher premiums for coverage.
-
Knob-and-Tube Wiring: Outdated and Unsafe
Knob-and-tube wiring was a common method of electrical wiring from the late 1800s through the early 1900s. While it was once considered cutting-edge, knob-and-tube wiring has since been deemed unsafe due to its lack of grounding and its vulnerability to deterioration over time. The wiring can become brittle, cracked, or even unsafe if insulation breaks down. Additionally, knob-and-tube systems often don’t meet modern electrical load demands, which increases the risk of overloads and electrical fires.
Insurance providers view knob-and-tube wiring as a significant safety hazard and, as a result, will typically require homeowners to replace it if they wish to secure coverage. In some cases, the insurance policy may be revoked if the wiring is not upgraded.
-
Outdated Electrical Panels: A Hidden Danger
Older electrical panels, such as Federal Pacific or Zinsco panels, are also a major concern for insurance companies. These panels have been linked to an increased risk of failure, which can lead to electrical fires. In fact, many insurance carriers have blacklisted these older panel types. Even if your wiring is up to code, an outdated or faulty electrical panel may not be able to safely handle modern electrical loads, and this increases the likelihood of an electrical failure or fire.
If your building or home has an old panel, it may be time for an upgrade. Modern panels are designed to meet the electrical demands of today’s homes and businesses, and replacing an outdated panel can reduce your risk of fire and help you avoid trouble with your insurer.
The Growing Trend: Insurance Companies Pushing for Electrical Updates
Due to the increased risk of fire and potential liability, many insurance companies are becoming more stringent about the type of electrical systems they are willing to cover. The result is a growing trend where insurers are requiring homeowners and business owners to replace outdated electrical components—often as a condition of maintaining or renewing their insurance policy.
Some insurance companies are more proactive than others in enforcing these requirements, but it’s clear that replacing aluminum wiring, knob-and-tube wiring, and outdated electrical panels is becoming a more common stipulation for coverage.
What Does This Mean for Property Owners?
If you own a property with outdated wiring or an old panel, you could face several challenges. Here’s what you need to know:
-
Potential for Increased Premiums or Denial of Coverage
If your home or building has aluminum wiring, knob-and-tube wiring, or an outdated electrical panel, your insurance company may increase your premium, or worse, refuse to cover you altogether. Without the proper coverage, you could be left vulnerable in the event of an electrical fire or other accident.
-
Necessary Upgrades to Stay Insured
In many cases, replacing outdated electrical systems is a necessary step to maintain your insurance coverage. The good news is that these upgrades not only make your property safer but can also improve its overall value. By replacing hazardous wiring or panels, you’re investing in both the safety of your family or employees and the long-term integrity of your property.
