Sobie Company

What Sobie Company does

Sobie Company is a privately held interior finishing construction subcontractor founded in the 1930s by Harold Sobie and headquartered at 3276 Hanna Lake Industrial Drive in Caledonia, Michigan. The company provides a comprehensive suite of interior finishing services for commercial and institutional construction projects across Western Michigan, including structural and light gauge framing, drywall hanging and finishing, acoustical wall and ceiling assemblies, flooring (wood, resilient/vinyl, terrazzo, fluid-applied, carpet, and access flooring), spray-on fireproofing, plaster and stucco systems, wall coverings, and tile installation. Sobie operates exclusively as a subcontractor to prime/general contractors rather than selling directly to end customers, generating project-based revenue through lump-sum bids and time-and-materials arrangements with pricing established per quote rather than via published rates.

The company maintains a portfolio spanning healthcare (Corewell Health, Spectrum Health), aerospace (GE Aerospace, with over $200,000 of work delivered on a single engagement), data centers (Switch), education (Michigan Career & Technical Institute, Calvin Theological Seminary, Portage Haverhill Elementary), hospitality (Hilton Garden Inn/Home2Suites, Canopy by Hilton), and government (Muskegon County Hall of Justice). Its go-to-market is sales-led and relationship-driven, with established partnerships across more than fifteen regional and national prime contractors including Skanska, CSM Group, Rockford Construction, Erhardt Construction, Miller Davis, Pioneer Construction, Wolverine Building Group, Lakewood Construction, Christman Company, Elzinga & Volkers, Owen Ames Kimball, and others. The internal organization is divided into specialized divisions covering Field Operations, Project Management, Preconstruction, LPDA (lead paint detection and abatement), Flooring, and Safety, supported by Vice Presidents, Directors, project managers, and a multi-person senior site supervisor team.

Ownership transitioned from the Austhof family (which held the company from 1965 until 2016) to Tony Vermaas in January 2016, with Jack Austhof remaining as Chairman of the Board. Sobie has been a member of the Associated Builders & Contractors (ABC) Western Michigan Chapter since 1985, winning the ABC Award of Excellence for Interior Finishing nearly every year since and being named Interior Finishing Contractor of the Year in both 2020 and 2022; in 2026 it was named to the ABC Top 250 Performers list as a top specialty contractor. Architectural Glass & Metals 2.0 (AGM) operates as a sister company to Sobie, together offering a combined building envelope solution encompassing glazing systems and exterior and interior finishing.
