When it comes to electrical safety, many homeowners focus on outlets, breakers, or visible wiring. However, during professional home inspections, we often spot small details that can cause big problems over time. One of these is the wrong type of screw inside an electrical box.


Why Screw Type Matters in Electrical Boxes

Electrical boxes are designed to protect wiring and electrical connections. Using the wrong screw—commonly sharp or self-tapping screws—can damage wires if installed incorrectly. Even minor contact with a wire can nick or compromise insulation, creating hidden electrical risks.

⚠️ Sharp screws can damage wiring insulation.
✅ Blunt-end, manufacturer-approved screws are designed to secure boxes safely without harming wiring.

This small detail is often overlooked but can prevent future electrical hazards.


Where This Problem Is Most Common

This issue is frequently found in:

  • Newly built homes in Edmonton and surrounding areas

  • Recently renovated properties

  • Homes with multiple trades working in tight spaces

Even when work is done carefully, small oversights like this can happen. That’s why professional inspections are essential.


How a Home Inspection Helps

Professional home inspectors look beyond the obvious. At Overview Property Inspection, we check for details like improper fasteners in electrical boxes to catch issues before they become costly or dangerous.

Early detection means homeowners can address concerns proactively, maintaining a safe and functional home.
