Kleen-Tech Services

What Kleen-Tech Services does

Kleen-Tech Services, LLC is a national janitorial and facility services provider founded in 1993 in Denver, Colorado, and operating as of September 2025 under the ownership of Seattle-based private equity firm Rainier Partners. The company delivers recurring cleaning and facility maintenance services through three core verticals: Commercial (businesses, retail facilities, corporate organizations), Government (federal, state, and local facilities including public libraries, courthouses, and high-security federal sites), and Specialty (research labs, cleanrooms, airports, and other uniquely configured buildings). The portfolio also includes Kleen-Protect, a branded enhanced cleaning and disinfection offering, and the company's service operations are supported by a proprietary work order management and tracking system that documents task status for transparency and accountability.

The business runs a B2B sales-led model targeting commercial, government, and specialty facilities across more than 30 states, with a workforce of approximately 2,000 employees organized under nine distinct brands serving over 20 million square feet of customer facilities. Revenue is generated through recurring service contracts — the company reports customer partnerships spanning over two decades — with quote-based pricing and monthly billing. The company does not publicly disclose revenue or financial figures, and holds state-level operating credentials such as Arizona ROC #347099. Customer acquisition is driven by direct outreach, a website quote-request channel, and phone-based sales (1-866-385-0672), rather than broad digital marketing.

Kleen-Tech has executed two notable corporate events in recent years: the 2023 acquisition of IFS Group, Inc. (advised by Caber Hill Advisors) to expand into eastern U.S. markets, and the September 2025 acquisition by Rainier Partners, which has stated plans to pursue organic growth and additional strategic M&A. The company has received Best of Clean (BOC) industry awards across multiple years from 2016 through 2024, and its differentiation rests on long-tenured customer relationships, a multi-brand delivery footprint, and proprietary work order tracking rather than on technology-led or AI-driven productization.
