W. L. Hall

What W. L. Hall does

W. L. Hall Company is a privately held, family-owned specialty building systems contractor founded circa 1950 and headquartered in Minneapolis, Minnesota, with a secondary office in Hartford, Wisconsin. The company designs, furnishes, and installs exterior and interior building envelope systems — including glass and glazing, Kalwall translucent panels and skylights, custom canopy and trellis systems, specialty fire/smoke door systems, operable and retractable space management walls, raised access flooring, and architectural interior finishes — for commercial construction projects across the Upper Midwest (Minnesota, Wisconsin, North Dakota, South Dakota, and surrounding areas). Customers include architects, general contractors, developers, building owners, and institutional facility managers across healthcare, education, commercial, hospitality, government, and corporate real estate segments.\n\nThe business operates a sales-led, project-based model in which the company engages clients at the pre-construction design-assist phase (scope definition, thermal/daylight modeling, budgeting, specification development) and delivers turnkey installation using its own in-house union labor force. Revenue is generated through project-specific, quote-based contracts complemented by aftermarket service, repair, and NFPA-compliant fire door and smoke draft curtain inspection. W. L. Hall maintains distributor or installation partnerships with roughly 15 specialty product manufacturers, including Kalwall, Barrisol, Skyfold, Modernfold, McKeon Door, Smoke Guard, Tate Access Floors, Euro-Wall, ZONA, Oldcastle Building Envelope, Wausau, CEAS+, Marlite, EFCO, and INOVUES, giving it a multi-product install capability uncommon for a regional contractor.\n\nThe company is led by President Craig Hall, with leadership historically anchored by long-tenured operators; Project Manager Mark Maddox retired after 36 years of service. Notable projects include the Lakewood Cemetery Welcome Center (an AIA Minnesota Excellence in Design for Energy award-winning zero-net-carbon visitor center), the Four Seasons Hotel Minneapolis, the North Loop Green transit-oriented mixed-use development, the Minnesota State Office Building historic renovation, and the Landmark Tower Apartments historic rehabilitation (2025 Rethos award winner). The company has completed over 15,000 projects cumulatively across its 75-year history.
