Case Study


Large fortune 500 company in an owner-occupied high-rise building



While NSG was a trusted partner since 1988 to the customer, the COVID-19 pandemic brought unprecedented challenges.  The customer quickly needed a new to the world janitorial cleaning program that was comprehensive, responsive, and still worked within their budget.


NSG listened to the customer and worked with them to develop a cleaning protocol that addressed their unique cleaning challenges.  The NSG janitorial team partnered with the customer every step of the way to deliver a program that included high touch disinfection for surfaces like elevators, conference rooms and door handles.  NSG also quickly recommended the addition of fine mist disinfection that included a 30-day germ barrier and the ability to test surfaces for germs before and after disinfection.


By reprioritizing cleaning to the daytime instead of night, the new recommended protocol was adopted, and costs were able to stay in budget.  The customer’s employees have returned to work and since June 2021, our disinfection data demonstrates an 78% decrease for weighted average Pre-Disinfection RLU’s across all locations which equates to a “hospital grade clean”.  Finally, to date, employee feedback indicates that they feel more comfortable being back at work with the new protocol and disinfection services.
