Things to Consider When Getting Commercial Electrical Work Done

Before starting a new construction or renovation project, it’s critical to plan your electrical scope properly. Here’s what to keep in mind:

Permits & code compliance: Every project must meet Connecticut State Building Code and National Electrical Code (NEC) standards. We handle permitting and inspections for you.
Power capacity: Commercial facilities require higher electrical loads. We size panels and circuits to handle current and future demand.
Lighting design: Proper lighting enhances productivity, safety, and customer experience.
Data and communication systems: Integrating low-voltage wiring early avoids costly rework later.
Coordination with other trades: Our team works directly with your GC, HVAC, and plumbing contractors to ensure efficient scheduling.
Energy efficiency: Incorporating LEDs, sensors, and automated controls reduces long-term operating costs.

Our electricians bring technical precision and field experience to every project — ensuring your electrical system supports your business now and into the future.

Cost of Commercial Electrical Construction & Renovations in Connecticut

Every commercial project is unique, but a few factors affect the cost of electrical construction and renovation services:

Building size and type: Retail, office, industrial, and mixed-use buildings all have different power requirements.
Scope of work: Full wiring for new builds vs. partial renovations or retrofits.
Materials and fixtures: The quality of panels, conduit, lighting, and control systems.
Complexity: Specialty systems like fire alarms, backup power, and data cabling add to project scope.
