Why Electrical Inspections Matter

Electrical issues are one of the leading causes of property damage and preventable fires. Many problems start small:

• Loose wiring
• Overloaded circuits
• Improper grounding
• Outdated panels
• Faulty breakers

Over time, these issues can escalate into serious safety risks.

A professional inspection helps you:

• Identify hidden hazards before they become emergencies
• Ensure compliance with current electrical codes
• Prepare for property sales or renovations
• Confirm system capacity for EV chargers, HVAC upgrades, or new appliances
• Protect your family, tenants, employees, and equipment

What We Inspect

Our inspection process is detailed, methodical, and designed to catch both obvious and hidden issues.

1. Electrical Service & Main Panel

Your panel is the heart of your electrical system.

We inspect:

• Service entrance wiring
• Proper grounding and bonding
• Breaker sizing and condition
• Signs of overheating or corrosion
• Double-tapped breakers or improper wiring
• Accessibility and proper labeling

If your panel is outdated or undersized, we’ll let you know before it becomes a bigger issue.

2. Sub-Panels & Branch Circuits

We verify:

• Secure mounting
• Correct breaker sizing
• Proper grounding and bonding
• Wire insulation condition
• Junction box accessibility
• Conduit integrity

Improper connections in these areas are a common source of electrical failures and safety concerns.

3. Outlets, Switches & Fixtures

Loose outlets or faulty switches aren’t just annoying—they can be dangerous.

We test:

• Outlet functionality
• Grounding and polarity
• Cracked or damaged faceplates
• Sparking or unusual switch behavior
• Secure fixture installation
• Exposed wiring or loose connections

In older homes especially, grounding and wiring issues are common and often overlooked.

4. GFCI & AFCI Protection

Modern code requires special protection in key areas.

We inspect and test:

• GFCI outlets in kitchens, bathrooms, garages, and exterior spaces
• AFCI protection in living areas and bedrooms
• Proper operation of test and reset features

These devices are critical for preventing shock and fire hazards.

5. Grounding & Bonding

Proper grounding protects both people and equipment.

We confirm:

• Approved grounding methods
• Proper bonding of panels and metallic systems
• Correctly sized grounding conductors

Improper grounding is one of the most dangerous hidden electrical issues.

6. Surge Protection

We evaluate:

• Whole-house surge protection (if installed)
• Protection for sensitive equipment (computers, HVAC systems, appliances)

With modern homes and businesses relying heavily on electronics, surge protection is more important than ever.

7. Smoke & Carbon Monoxide Detectors

Safety devices only work if they’re installed and functioning properly.

We verify:

• Proper placement
• Functional testing
• Expiration dates

These small devices save lives—regular checks matter.

8. HVAC & Major Appliances

We inspect:

• Electrical connections to HVAC systems
• Breaker and fuse sizing
• Dedicated circuits for major appliances
• Proper grounding

Improper electrical connections can shorten equipment life and create fire risks.

9. Code Compliance & Permitting

We ensure:

• Work meets local and national electrical codes
• Proper permits and inspections (when applicable)
• Required safety markings are present

Whether it’s a residential home or a commercial property, compliance protects you from liability and future issues.
