Our Service
Commercial Electrical Services for Projects, Properties, and Facilities
E-1 Electrical supports commercial buildings across Calgary with electrical construction, service work, equipment connections, lighting upgrades, troubleshooting, and maintenance. Our work is built for the realities of occupied spaces, tenant schedules, GC coordination, inspections, and long-term building operation. From tenant improvements and base building electrical to service calls, panel work, lighting, data cabling, and mechanical equipment connections, we focus on clean execution, practical communication, and electrical scopes that are easy to maintain after turnover.

Electrical rough-ins, fit-outs, lighting, power, and coordination for commercial tenant spaces.

Commercial LED Installation
Better Lighting for Storefronts, Workspaces, and Commercial Buildings
Lighting has a direct impact on how a commercial space looks, feels, and functions. E-1 Electrical helps Calgary businesses upgrade older fixtures with commercial LED lighting that can improve visibility, create a cleaner customer experience, reduce maintenance demands, and support safer, more usable work areas. From storefront lighting and office interiors to exterior wall packs, flat panels, highbays, and lighting controls, we plan LED installations around the space, the existing electrical conditions, and the way the building is used.
