You may think your home or business is fire-safe, but fires are always a concern when it comes to old wiring. Even simply putting nails in a wall can easily put a hole in your electrical wiring, causing electrical issues you have to face later.

If you are looking to rewire your Minneapolis, Minnesota home or business, contact the electricians at Randy’s Electric online or give us a call at 612-470-0914.

Here are six ways that your old and outdated wiring could be a fire hazard for your home or business:


Older buildings and homes tend to have what is known as “knob and tube” wiring. Knob and tube wiring consists of copper conductors that run within the wall or ceiling, passing through drill holes via porcelain tubes and supported along their length with knob insulators. This design isn’t much of an issue until it’s compromised by a nail, chewed by a rodent, or even enveloped by building insulation. Then, it becomes one of the leading causes of electrical fires, according to insurance companies.

To get secure and trusted wiring in your home, trust the electricians at Randy’s Electric. Contact us online or give us a call at 612-470-0914.


In older buildings and homes, particularly those around 100 years old, it’s not uncommon for wiring to have been modified over the years by people who were trying to get a job done quickly with no proper electrical training. This can mean that you have faulty wiring in your home. Check for buzzing, flickering, or dimming lights and burn marks around outlets.


Appliances have come a long way since your old wiring was installed; we’re using many more appliances today than we ever have before. Older wiring can sometimes be rated for lower amps than is required by the appliances we use today. This can result in circuits being overloaded, which can cause a fire.

Upgrading your electrical service panel can be one solution to low amp wiring. If you are looking to upgrade your service panel, choose Randy’s Electric in Minneapolis, MN. Contact our team online or give us a call at 612-470-0914.


Insulation on older wiring will eventually deteriorate and become damaged. Over the years, it may have been chewed by mice, been damaged by nails being placed in walls, or simply disintegrated from old age. Without sufficient insulation on your wires, they’re left exposed, which can lead to sparks and a fire.


Wiring isn’t the only risk in older buildings. If your electrical panel is old, it’s possible that the switches and breakers that make up the circuits might be faulty. If they’re not working correctly, your electrical system won’t do what it is supposed to do, which can lead to expensive problems in the future.

If you are in need of breaker panel services, contact Randy’s Electric online or give us a call at 612-470-0914.


Poor electrical design is another major problem for older buildings. Electrical codes and standards have changed and improved over the years, meaning your home or business may not meet the current safety requirements. Even if your building was built in the 70s or earlier, there could be some electrical concerns hiding in your walls. If you’re not sure, then the best idea is to have an experienced electrical company come out for an inspection and make sure there aren’t any major fire risks.
