What Windemuller, Inc. does
Windemuller, Inc. is a privately held, family-owned electrical contracting and technical design-build firm headquartered in Grandville/Wayland, Michigan. Founded in 1954 by Edward Windemuller and Henry Feyen as Feyen & Windemuller, the company has grown from a two-person operation out of a chicken coop to approximately 250 employees and a reported ~$50M in annual revenue. It operates seven offices across Michigan — Grandville, Traverse City, Midland, Wayland, Big Rapids, Whitehall, Charlevoix, and Kalamazoo — and is led by fourth-generation president Steve Alles, who succeeded Dave Beemer in December 2021.
The company's core offering spans seven integrated service lines: Automation (HMI/SCADA programming, PLC design and programming, process controls, UL-listed panel design and construction), Electrical Services (design-build, engineering, lighting, fire alarms, generators, BIM, prefabrication), Communications Systems (access control, audio visual, fiber optics, structured cabling, video security), Information Technology (network services, virtualization, disaster planning, WiFi), Maintenance Partnerships (ARC flash studies, infrared inspection, PLC/HMI/SCADA maintenance, wind turbine maintenance), Outdoor Utilities (traffic signals, substations, street lighting, distribution), and Renewable Energy (utility-scale wind, PV solar, EV charging stations, interconnection substations). Strategic vendor relationships include Rockwell Automation Recognized System Integrator status, Corning Optical Communications NPI preferred installer status, and certified installer partnerships with ChargePoint, Blink, Leviton, EvoCharge, Xeal Energy, and Tritium for EV charging.
Windemuller earns revenue through professional services on a project-based, quote-driven model, sold through direct field sales to enterprise industrial, municipal, healthcare, commercial, and educational clients throughout Michigan. It serves named accounts including Dow Chemical, BorgWarner, Amazon, Spectrum Health, Munson Healthcare, Ascension Borgess, DeVos Place Convention Center, Great Wolf Lodge, and the City of Grand Rapids. Growth has historically come through inorganic means — three acquisitions since 1991 (Ennis Electric, Top Rail Electric, Hovey Electric) — combined with organic expansion into adjacent verticals like EV charging and renewable energy. A 24/7 service department, an average EMR safety rating of 0.86, and 2024 Best and Brightest Companies recognition underpin a brand reputation built over 70 years.
