Electrical Contractors in Madison, WI.

Commercial Electrical Services

Madison owners and general contractors need an electrical contractor they can hold accountable. Our licensed master electricians lead in-house crews through the full construction electrical scope: temporary power, rough-in, feeders, and device trim-out, from preconstruction to closeout documentation.

Our commercial electrical services in Madison include power distribution, with switchgear, transformers, panelboards, and feeder systems for offices, clinics, and public buildings, plus commercial lighting from LED retrofits to exterior and site lighting.

Industrial & Lab Facilities

Industrial facilities and labs can't afford unreliable power. As an industrial electrician for Dane County manufacturers, we deliver plant electrical, high voltage distribution, and maintenance-friendly infrastructure for facilities that measure downtime in dollars, and our crews build and maintain high voltage systems, including substations, transformers, and medium-voltage switchgear.

We also deliver electrical work for lab facilities, where power distribution, equipment circuits, and building systems have to be planned around the work happening inside.

Design-Build & Preconstruction

Good electrical work starts before the first conduit is set. Our preconstruction support and budgeting give Madison projects pricing to plan around, and our in-house BIM specialists model the electrical scope in Revit to catch clashes and review constructability before rough-in, so problems get solved on screen instead of in the field. Learn about our design-build, preconstruction & BIM services.

Low Voltage & Controls

Low voltage work in Madison runs through the same team as the power. We install fire alarm, security camera, access control, and building automation systems, all part of our low voltage systems, along with structured cabling for offices, clinics, and campus buildings through our network & data cabling crews.

Permitting & Inspections in Dane County

Madison-area projects move through local permitting and inspections, and the details can vary between the City of Madison and the surrounding Dane County communities. Our team is familiar with Dane County permitting, so inspection milestones are built into the electrical schedule during preconstruction rather than discovered at closeout. Rough-in inspections have to happen before walls and ceilings close, and final inspections need to line up with occupancy dates, so coordinating those steps with the general contractor keeps the rest of the trades moving. When a project also includes mechanical work, one contractor handling both scopes means one set of inspection dates to track instead of two.

Planning Electrical Work for Labs & Clinics

Labs and clinics place specific demands on an electrical system. Equipment lists should be settled early, because dedicated circuits, backup power needs, and equipment locations drive panel sizing and feeder routing. Owners should also identify which spaces must stay operational during construction, whether any equipment is sensitive to power quality, and how future equipment additions might affect capacity. Settling those answers during design costs far less than rerouting circuits after rough-in. Leaving spare panel space and conduit pathways for the next round of equipment is a small cost now that can save a disruptive retrofit later.

Preparing a Madison Project for Bid

Accurate electrical pricing depends on what the estimator can see. Before a Madison bid, gather current drawings and specifications, the delivery method, a target schedule, and any known site constraints such as occupied floors, restricted work hours, or limited laydown space. For existing buildings, share the service size, the age of major distribution equipment, and any recent arc flash study. Wisconsin winters matter too: exterior lighting, site work, and service upgrades that require an outage are easier to plan when the schedule accounts for cold weather and short days.

Madison Electrical Projects

Wisconsin History Center. Five stories and 100,000 square feet of museum-grade electrical, lighting, and low voltage systems, doubling exhibit space for the Wisconsin Historical Society. Our work, underway since 2025, will power classrooms, public galleries, rooftop terraces, and state-of-the-art tech systems.
