Commercial Troubleshooting & Repairs
A tripped breaker or intermittent power drop during business hours isn't just inconvenient – it's revenue walking out the door. We diagnose fast, fix right, and document the repair so it doesn't come back.
Tenant Build-Outs & Tenant Improvement Electrical
Opening a new space or renovating an existing one? We handle the full electrical scope – from load calculations and commercial building wiring through permit management and final inspection – coordinated directly with your GC so electrical is never the bottleneck.
Panel & Sub-Panel Upgrades – Commercial Power Distribution
Adding new HVAC, kitchen equipment, or expanding your server room? Your panel may not be keeping up. We size and install commercial panel upgrades based on your actual load – not a generic estimate – and handle the permit from start to close.
Commercial Lighting Installation & LED Retrofits
A well-executed LED retrofit cuts lighting energy costs by 40–60% – with no major construction. We design and install energy-efficient commercial lighting for offices, warehouses, retail floors, and restaurants, including occupancy sensors and dimming controls.
Emergency & Exit Lighting
Illinois code requires emergency and exit lighting to work the moment power fails – not sometimes, always. We install, test, and service battery-backed fixtures and illuminated exit signs for all commercial occupancy types, with documentation for annual compliance.
Dedicated Circuits for Equipment
HVAC units, walk-in coolers, commercial kitchen lines, and server room UPS systems all need their own circuit. Sharing loads creates tripping, equipment damage, and real fire risk. We engineer dedicated circuits sized to your equipment's nameplate specs, with proper disconnects and permits. Common applications: restaurant kitchen circuits, refrigeration, HVAC hookups, dedicated circuits for server rooms, EV charger feeds.
Power for POS, IT & Workstations
One power interruption to your POS network means lost transactions and a manual close. We build the electrical backbone that keeps retail and hospitality systems stable – dedicated circuits, isolated grounds, conduit for structured cabling, and surge protection where it counts.
EV Charger Installation (Commercial)
EV charging is becoming a tenant amenity, an employee perk, and in some Illinois municipalities – a zoning requirement. We install Level 2 and DC Fast Charger infrastructure for parking lots, corporate campuses, and retail properties, including load analysis, wiring, and permit filing.
Exterior & Parking Lot Lighting
A poorly lit parking lot is a liability and a deterrent to after-hours business. We design and install LED area lighting, wall packs, pole-mounted fixtures, and photocell or timer controls for commercial properties – built for safety, security, and curb appeal.
Inspections, Code Violations & Compliance
A violation notice has a deadline. Whether it's outdated wiring, missing GFCI protection, or a failed inspection, we resolve code violations fast and document the correction for reinspection. We also offer proactive inspections for property acquisitions and pre-lease walkthroughs. Services: code violation correction, NEC compliance audits, pre-purchase inspections, AHJ reinspection support.
Surge Protection & Power Quality
One voltage spike can take out a POS system, a server, or precision equipment. We install commercial-grade Surge Protective Devices (SPDs) at the service entrance and individual panels – rated to UL 1449 standards and matched to your service voltage.
Equipment Disconnects & Electrical Hookups
New equipment, a machinery swap, or a facility reconfiguration all need a proper disconnect and hookup under NEC and local code. We handle commercial HVAC, rooftop units, compressors, and commercial kitchen equipment – permits and inspections included.
NEW CONSTRUCTION:
Electrical Solutions
We handle complete commercial electrical installation for new builds and additions – temporary power, underground conduit, rough-in, above-ceiling work, devices, and final trim. We read MEP drawings and coordinate with other trades to keep the schedule on track.
Ground-Up & Addition Electrical
The service entrance sets the capacity ceiling for the entire building. We design and install commercial-grade switchgear, main distribution panels, sub-panels, and metering – sized to current NEC standards and local utility requirements, with clean labeling from day one.
Service Entrance, Panels & Power Distribution
New construction is the right time to get lighting right. We install complete interior and exterior systems – office LED layouts, high-bay warehouse fixtures, retail track lighting, and parking lot lighting – integrated with occupancy sensors, daylight controls, and building automation hookups.
Interior & Exterior Lighting with Controls
Life safety systems must be code-compliant from the first inspection, not corrected after. We install emergency lighting and exit sign systems that meet IBC and local fire code, coordinated with the fire alarm contractor and documented for your Certificate of Occupancy.
Emergency & Exit Systems (Life Safety)
The last 5% of a project is where delays get expensive. Our punch list team closes open electrical items quickly, coordinates with inspectors, and gets the sign-off done so your client takes occupancy on schedule – under Illinois, Cook County, and Elk Grove Village permit requirements.
