About Flagship Facility Services
Flagship Facility Services is a large independent facility services company with a Denver presence. Beyond janitorial work, its website describes broader facility support. On the cleaning side it lists recurring janitorial service, post-construction cleanup, floor care, carpet and window cleaning and disinfection, for offices, industrial and warehouse sites, schools, retail, restaurants and kitchens, churches, government buildings, and labs and cleanrooms.
The website says cleaning is done by Flagship's own employees, describes a staff training program, and lists ISSA CIMS and GBAC STAR credentials. Evening and after-hours cleaning is available. The company's website also emphasizes data and reporting for facility managers.
On Google, Flagship's Denver listing has a 3.0 rating from only 4 reviews, so the rating says little about the company either way. Buyers with complex sites, such as campuses, labs or multi-building properties, should ask how Flagship's broader facility services could be combined with cleaning. Ask about the local team that would manage your account and request references from Denver-area clients.
