Our Services: Commercial Electrical Maintenance & Diagnostics
Exterior Lighting & Repairs
Professional exterior Lighting Maintenance and repairs are essential for safety, security, and a polished first impression. Properly functioning pole lights and building-mounted fixtures deter theft, reduce trip-and-fall liability, and keep parking lots and walkways code-compliant. Because many exterior issues are out of reach, our team provides bucket-truck service (up to 50 feet) to quickly restore reliable lighting on taller poles and hard-to-access fixtures.

24/7 Emergency Response
We provide 24/7 emergency electrical response services across Southeastern Wisconsin. Our focus is rapid fault detection, system stabilization, and restoring critical power to reduce downtime and financial loss.
Energy Efficiency Lighting Upgrades
Energy Efficiency Lighting Upgrades often result in 30% to 75% savings on lighting-related energy consumption. We retrofit outdated fluorescent and HID fixtures with modern, high-efficiency LED systems, also reducing long-term maintenance costs.

Troubleshooting & Repair
Professional Troubleshooting & Repair involves expert diagnosis of complex electrical faults, such as intermittent tripping or short circuits. Our licensed technicians use advanced tools to pinpoint the root cause—not just the symptom—and implement a lasting solution quickly.
Arc Flash & Coordination Studies
An Arc Flash Study evaluates electrical systems to calculate fault energy levels, ensuring compliance with NFPA 70E and OSHA safety requirements. It defines safe work zones and PPE standards for worker protection.
Infrared Scanning
Infrared Scanning (thermal imaging) detects hidden electrical issues such as overloads, loose connections, and overheating components. This predictive maintenance tool helps prevent unexpected system failures and downtime.
Feasibility Studies
A Feasibility Study is an essential technical evaluation used to determine if your current electrical system can support future demands. You need one before major expansions, large equipment installation, or planning new infrastructure like EV Charging Stations.
EV Charging Stations
We provide end-to-end installation and maintenance of Commercial EV Charging Stations for fleets, employee amenities, and customer parking. This includes necessary electrical service upgrades and integration with your existing power infrastructure.
