Sizemore, an integrated facilities management company backed by Los Angeles-based private equity firm Inspirit Equity, has signed a definitive agreement to acquire Carlson Building Maintenance, a Minneapolis-based janitorial and facility services provider serving retail, grocery, and commercial customers across the Midwest. Financial terms were not disclosed.
Founded in 1959, Carlson has operated for more than 65 years and serves a blue-chip customer base across more than 250 locations in 10 states. The company’s operating model is built around a fully self-performing workforce — meaning it does not subcontract cleaning labor — and has developed long-tenured client relationships in the retail and grocery sectors. Current owners Nick Giese and Kaylee Brown will continue to lead the business and remain actively involved in operations following the close.
Carlson will operate as a dedicated retail-focused division within Sizemore, preserving its existing leadership team, workforce, and customer relationships rather than being absorbed into Sizemore’s broader structure. The transaction simultaneously expands Sizemore’s Midwest footprint and establishes a distinct retail vertical within the platform — a move Inspirit Equity described as foundational to its strategy of building a national facilities management provider through regional add-on acquisitions.
Inspirit Equity invests from a permanent capital base with a long-term ownership orientation, focusing on businesses with strong operational fundamentals and room for structured growth through infrastructure investment and acquisitions.
