Sizemore Inc., a portfolio company of Inspirit Equity, has agreed to acquire Carlson Building Maintenance, a Minneapolis‑based provider of janitorial and facility services to retail, grocery, and commercial customers across the Midwest.

Carlson, founded in 1959, will continue to operate under its existing owners, Nick Giese and Kaylee Brown, who will remain actively involved in day‑to‑day operations. The acquisition allows the company to expand its service footprint while maintaining its local leadership.

The deal brings together two firms with complementary strengths. Sizemore, headquartered in Augusta, Georgia, specializes in integrated facilities management, whereas Carlson’s focus on janitorial services positions it well to serve a broad customer base.

With the backing of Inspirit Equity, the combined entity will leverage shared resources and expertise to enhance service delivery across the Midwest. The continued involvement of Giese and Brown ensures continuity of customer relationships and operational stability. This strategic move also aligns with Inspirit Equity’s focus on growth opportunities within the facilities management sector.
