About One Source Denver
One Source Denver is a cleaning broker: rather than employing its own cleaning crews, it arranges and manages commercial cleaning that independent contractors from its vendor network perform. Its website lists recurring janitorial service, porter service, floor care, carpet and window cleaning and disinfection, for facilities including offices, medical spaces, industrial and warehouse sites, schools, restaurants, churches, apartment and HOA properties, gyms and car dealerships. City pages cover Denver, Westminster, Louisville, Littleton, Lakewood, Golden and other areas.
The website describes a client services portal for tracking visits, billing and requests, and offers a free walkthrough before quoting. Colorado Secretary of State records show the current entity, One Source Denver, Inc., registered in December 2025.
One Source Denver has a 5.0 rating from 8 Google reviews; of the 7 most recent, 3 mention reliability, 3 communication and 2 thoroughness. Because the cleaning is outsourced, ask who the actual cleaning vendor will be, how that vendor is screened and insured, and who is accountable when work is missed.
