Commercial Electrical & Mechanical Contractors in Green Bay, WI.

Contractors Serving Green Bay & Brown County

WIL-Surge Electric is a family-owned, third-generation commercial electrical contractor that has served Wisconsin since 1993. Green Bay businesses looking for a commercial electrician get more than 30 years of Wisconsin experience behind every job, delivered by in-house crews from our Butler headquarters.

We self-perform electrical, mechanical, and civil work under Wisconsin electrical contractor license #1103087-EC, so Green Bay owners and general contractors get one contract, one schedule, and one team accountable for the build.

Electrical Services

Our licensed master electricians lead the full commercial and industrial electrical scope for Green Bay projects:

• Power distribution
• High voltage systems
• Commercial and industrial lighting
• Low voltage systems
• Network & data cabling
• Design-build, preconstruction & BIM

Construction electrical, arc flash studies, and electrical service round out the work. See every service on our commercial electrical contractors page, or go deeper on our electrical contractors in Green Bay.

Mechanical & HVAC

For commercial HVAC in Green Bay, our crews handle HVAC installation and replacement, including rooftop units, chillers, boilers, VRF, and ventilation, along with building automation controls and planned maintenance agreements. We hold Wisconsin HVAC contractor license #1029-HVACCONT, EPA 608 certified technicians handle refrigerant, and the same company carries your electrical scope.

Industrial Market Strength

Green Bay runs on industry, and so does much of our work. We serve the region's paper mills, port facilities, and industrial plants with plant electrical, high voltage distribution, and maintenance-friendly infrastructure for operations that measure downtime in dollars.

We install the switchgear, switchboards, and distribution equipment that form the backbone of industrial facilities, with HVAC and mechanical work delivered alongside. Elsewhere in Wisconsin, the same crews are renovating the occupied Waukesha County Courthouse and delivered the 310,000+ ft² West Allis DPW campus and the Racine Unified Aquatic Facility. See our manufacturing and industrial work or our projects.

Planning a Project in Green Bay

Commercial and industrial projects in Green Bay go smoother when the electrical, mechanical, and civil scopes are defined together before bids go out. Owners and general contractors should have current drawings and specifications, a target schedule, and a clear list of what has to stay running during construction. For existing plants, record drawings, single-line diagrams, and equipment lists help an estimator understand the system before a site walk, and confirming the available utility service capacity early can prevent a costly redesign later.

Working Around Plant Shutdowns

Paper mills and industrial plants often concentrate major electrical and mechanical work into planned shutdowns, when production lines can be taken offline for a set window. That window leaves little room for surprises, so the preparation happens well before it opens: long-lead equipment such as switchgear and transformers ordered in advance, materials staged, and the sequence of disconnects, installation, testing, and re-energization mapped out step by step. Work that can be done safely ahead of time, such as conduit runs and equipment supports, shortens the outage itself. Arc flash labels and safety procedures should also reflect the system as it will exist after the change, not just before it.

Scheduling Around Green Bay Winters

Green Bay winters are long, and they shape construction schedules. Frozen ground complicates trenching and underground conduit, cold and wind make rooftop equipment setting harder to schedule, and heating systems carry the most risk when they are replaced in the middle of the season. The practical approach is to plan outdoor and rooftop scopes for warmer months, schedule boiler and heating work before cold weather arrives, and use winter for interior electrical and mechanical work where conditions allow. Because we carry electrical, mechanical, and civil work under one contract, those seasonal tradeoffs are planned on a single schedule instead of negotiated between separate subcontractors.

Choosing a Contractor for Green Bay Work

Before awarding electrical or mechanical work, find out who will actually be on site, whether crews are in-house or subcontracted, which Wisconsin licenses the company holds, and how its safety program is built. For industrial facilities, it is also worth understanding how a contractor plans outages and coordinates with plant maintenance staff. WIL-Surge brings in-house crews, Wisconsin electrical and HVAC contractor licenses, and a safety program built on NFPA 70E standards to every Green Bay project.

Licensed, Bonded & Safe

WIL-Surge has operated as a licensed, bonded, and insured Wisconsin electrical contractor since 1993, with DSPS-credentialed master electricians and journeymen. Our crews work under a safety-first program built on NFPA 70E standards, and prequalification documents, including licenses, bonding capacity, and insurance certificates, are available on request. Review our safety record and prequalification.
