Most older homes offer space, style, and character that just can’t be achieved by newer homes. When well-maintained, older homes provide value, especially when combined with modern renovations. However, most homeowners focus on the roof, landscape, and other significant parts of the house and completely ignore the electrical wiring in the home. If you’re looking to purchase or sell an older home in Middletown, Miller Premier Services recommends having your outdated electrical system inspected by a professional electrician to prevent serious issues like fires in the future. Our skilled electricians are well-versed with the electrical needs of commercial and residential property and ensure your electrical system is up to code.

How Dangerous is Electrical Wiring in Your Old Middletown House?

Old electrical wiring that has not been inspected by an electrician for a long time (over ten years) is extremely risky and dangerous. Older systems like black rubber and VIR cables are prone to wear and damage, leading to fire hazards in the home.  That’s why we advise older homeowners to consider modern electrical upgrades in DE and schedule professional inspections every year to rule out any electrical issues. This is more critical if your home is older than 40 years.

Can You Keep Your Home’s Old Wiring in Middletown, DE?

Some homeowners prefer to keep older wiring and preserve the house’s original electrical system, and we usually don’t have a problem with this. However, it’s essential to know the type of existing wiring to determine whether it is safe to keep it or not. For instance, most older homes were installed with knob-and-tube wiring, which can remain in use, according to the National Electrical Code.  To add life and durability to the system, you can add extensions to the knob-and-tube systems. Historical homes are also permitted to conduct restoration work on their knob-and-tube systems provided the suitable materials and techniques are used.

Common Signs of Old Electrical Systems to Look Out For in an Older Home

The electrical system in an old house becomes dangerous when the insulation wears away during renovations, alterations or improper practices in the house that can cause the wiring to overheat and start a fire. Here are some common signs that indicate potential problems with your electrical system:

  •         The circuit breaker keeps tripping
  •         Unusual power draws and dimming or flickering lights
  •         You hear hissing sounds from various switches and outlets
  •         Dark-colored outlets that are warm to touch
  •         Unusual odors like plastic burning that you can’t find the source
  •         Your home is typically older than 40 years

Should You Change Your Old House’s Electrical System Even if it is Working Just Fine?

According to the US Consumer Product Safety Commission (CPSC), many older homes still have outdated wiring. However, having outdated wiring doesn’t mean you must change it, but you might want to for your family’s safety.  Most old electrical systems are not designed to handle the heavy electrical load of today’s modern appliances. We rely on electricity to perform almost every task at home. As a result, the system can overload and the outdated wiring can quickly overheat and burn down your home.
