About the company
Probst Cleaning Service, Inc., a veteran-owned small business headquartered in Glasgow, Montana, provides janitorial and custodial services to federal agencies exclusively as a prime contractor under total small business set-asides. The vendor operates as a Subchapter S corporation and competes solely under the Total Small Business set-aside category across its federal footprint.
Probst's capability portfolio is narrowly focused on routine janitorial and facilities maintenance services. Recent representative work includes a $10,800 firm fixed-price purchase order from the National Oceanic and Atmospheric Administration (NOAA) awarded in August 2026 for standard janitorial services performed three times per week at the National Weather Service Weather Forecast Office in Glasgow, Montana, running through July 31, 2027; a $7,200 purchase order from NOAA in October 2024 covering routine janitorial services at the same Glasgow Weather Forecast Office for a nine-month base period; and a $39,780 purchase order from the Western Area Power Administration awarded in February 2022 for janitorial and custodial services at the Montana Maintenance Office in Fort Peck, Montana, with an ultimate completion date of March 1, 2027.
Customer concentration is bimodal by dollar value. The Department of Energy's Western Area Power Administration and the Department of Commerce's NOAA together account for 84% of combined potential value across all awards, though the two agencies rank differently: WAPA leads on dollars ($147 thousand across 3 awards) while NOAA leads on award count (8 awards, $124 thousand combined potential value). The vendor has served only these two agencies across a 17-award footprint spanning two decades of activity. Two awards totaling $51 thousand in combined potential value complete within the next twenty-four months and face recompete. Probst maintains no subcontract relationships and operates no parent vehicles or IDVs.
