Our Approach to Electrical Inspections

Every check is designed to be thorough, organized, and genuinely useful. We evaluate your entire electrical system, focusing on both current safety and long-term performance. Rather than just identifying code violations, we provide practical insight into how your system can operate more reliably and efficiently.

Here’s what our inspection typically includes:

• Panel and circuit assessment. We check breaker panels, fuses, and circuits for wear, corrosion, and overloading. A balanced panel helps prevent nuisance trips and protects your entire system.
• Wiring evaluation. Outdated or damaged wiring poses serious risks. We review visible wiring, grounding, and terminations to identify potential fire or performance concerns.
• Outlets, switches, and fixtures. Each outlet and switch is tested for proper wiring and grounding, including GFCI protection where required, especially in kitchens, bathrooms, and outdoor areas.
• Lighting systems. We inspect both interior and exterior lighting for safe operation, code compliance, and overall efficiency.
• Smoke and fire alarm systems. For homes and commercial properties, we confirm that detectors and alarm circuits are in proper working order.
• Specialty systems. Our team also reviews electric vehicle chargers, pool and spa connections, smart home setups, and low-voltage systems such as security or data networks.

Following the inspection, we provide a clear overview of your system’s condition, identifying any areas that need attention or could benefit from upgrades.
