VerHalen, Inc.

What VerHalen, Inc. does

VerHalen, Inc. is a 114-year-old, family-owned Wisconsin holding company operating two distinct divisions: Pella Windows & Doors of Wisconsin and VerHalen Construction (also branded VerHalen Commercial Interiors). The Pella division, in continuous partnership with Pella Corporation since 1925, distributes premium residential and commercial windows, sliding glass doors, French doors, skylights, and entrance doors through showrooms in De Pere, Brookfield, and Madison, selling to homebuilders, architects, homeowners, and general contractors. The construction division, originating in 1935 with acoustical ceilings, provides commercial interior subcontracting — metal framing, drywall, firestopping, insulation, acoustical ceilings and panels, specialty ceilings, baffles, and acoustical design/analysis — for general contractors and construction managers across Wisconsin, representing manufacturers such as Armstrong World Industries, USG, ClarkDietrich, National Gypsum, CertainTeed, Chicago Metallic, Georgia-Pacific, and Hilti.

Revenue is generated through two mechanics: (i) project-based commercial interior construction contracts bid directly to general contractors, construction managers, and owners, and (ii) hardware and installation sales of premium windows and doors through showrooms and direct field sales. Pricing is quote-based on both sides; the company does not publicly disclose pricing or revenue. Customer concentration is moderate, with construction revenue dependent on a recurring set of Wisconsin-based GCs (Miron, CD Smith, SMA, Mortenson, Ganther) and completed-project references spanning healthcare (Bellin Hospitals), hospitality (Potawatomi Casino, Hotel Northland), food and beverage (Sargento), sports (Titletown), and cultural/educational (Kohler Arts Center, NFDL Friendship Learning Center) end markets.

In 2023, John Calawerts and his wife Anne acquired 100% of the company; in 2025, the company opened a new 85,000-square-foot consolidated showroom, warehouse, and office in De Pere, WI. Headcount is 101–250, the operating geography is Wisconsin-only, and the business carries no disclosed AI/ML capabilities, no external funding, and no parent company.
