What distinguishes Service by Medallion is their investment in proprietary cleaning technology and dedicated divisions for complex assignments. The OPTIHEALTH system reflects their focus on indoor air quality and sanitization, while their Construction Clean Up Division handles post-build heavy-duty projects that overwhelm standard cleaning crews. During the COVID-19 pandemic, they developed enhanced protocols specifically addressing pathogen control in commercial spaces. Their facility services include temporary staffing, giving them capacity to scale crew size for large-scale or urgent projects.

Multiple reviewers specifically praise the professionalism and effectiveness of crew members, with one long-form review referencing their expertise as among the most educated cleaning professionals in the region. Negative feedback centers on isolated instances of communication breakdowns, though even critical reviewers acknowledge the technical competency of the cleaning work performed.
