Wiring Inspection

Wiring Inspection

Home wiring inspections have gotten complicated with all the testing methods, warning signs, and professional certifications flying around. As someone who has inspected wiring in homes from every era, I learned everything there is to know about what to look for and when to worry. Today, I will share it all with you.

What Lurks Behind Your Walls

Probably should have led with this section, honestly—your home’s wiring works invisibly until something goes wrong:

Regular inspections catch problems before they cause fires or equipment damage. Homes over 40 years old especially benefit from professional wiring evaluation.

Warning Signs You Can See

That’s what makes visual inspection endearing to us safety-conscious homeowners—some problems are obvious:

  • Discolored outlets suggest overheating
  • Warm switch plates indicate loose connections
  • Sparking when plugging in devices means wiring problems
  • Burning smells with no visible source often indicate overheating wires inside walls

Take these warnings seriously—they don’t go away on their own.

The Professional Inspection Process

Professional inspections examine your panel, test outlets for proper grounding and polarity, and evaluate visible wiring for damage. Thermal imaging can reveal hot spots in walls that indicate problems. Most inspections take 1-2 hours.

When to Schedule

  • Before buying a home
  • After any flooding or storm damage
  • When adding major appliances
  • Every few years for older homes

The small cost of inspection prevents expensive repairs and dangerous situations.
