Compare between DLL Cleaning and other vendors

DLL Cleaning Services is a New York–based commercial cleaning provider founded in 2013 and formally established under its current name in 2018. Headquartered in Manhattan, the company focuses on tailored cleaning solutions for offices, medical practices, multi-tenant buildings, and other professional environments. Their service model centers on walkthrough-based planning, allowing cleaning schedules and scopes to reflect how a space is actually used rather than relying on preset packages. Offerings include routine janitorial services, deeper cleaning for higher-demand situations, and optional disinfection, with flexibility built around client operating hours. Consistency plays a key role, as many clients work with assigned teams and benefit from company-provided equipment and supplies. Public feedback points to strong satisfaction with ongoing service quality once routines are established, alongside some notes about slower communication during onboarding. From an industry standpoint, the company holds an A+ rating with the Better Business Bureau, though it does not list additional third-party cleaning certifications.
