Disinfecting Services

Helping our clients provide the healthiest facilities possible for their employees, tenants, and guests

Break the chain of infection

Marsden’s Microbial Preventative and Remediation program is a standardized disinfecting program that helps break the chain of infection in a facility.

Our comprehensive program has been established through collaboration with the CDC, the WHO, and our disinfecting chemical suppliers to determine the appropriate response. As new diseases are identified and mutate, we work carefully with the CDC, WHO, and our suppliers to adjust our program accordingly as necessary.

Our Microbial Preventative and Remediation program helps break the chain of infection and reduce the likelihood of an infection in the facilities we service.

While no disinfecting program can ensure that no infections will occur in a workplace, research demonstrates that a thorough program for disinfecting microorganisms from surfaces can help break a chain of infection and mitigate the risk of infection.

Our goal is to help clients mitigate the impact of an epidemic in their facilities. Our program includes CDC-recommended competencies in addition to Marsden processes.

To best accommodate each client’s unique needs, we created different levels of our service that vary with the severity and prevalence of a disease.

  • Marsden uses EPA-registered, hospital grade disinfectants to disinfects all touchpoint surfaces as directed by the client. Common touchpoints we would disinfect include door handles, light switches, handrails, time clocks, keyboards/mouses, vending machines, faucets, phones and headsets, copier screens, and chair armrests.


  • Level 2 uses the same disinfectants and touchpoint sanitation as Level 1, but Level 2 includes a process for precleaning, disinfecting, and when necessary, electrostatic fogging. The entire area – or building – is vacated and everything below ceiling level is disinfected according to the following process: precleaning of all surfaces of building components and building personal property; disinfecting of all surfaces within the building/area and all personal property; deploying electrostatic fog disinfectant treatment of interior surfaces if necessary; utilizing ATP testing to confirm disinfection; and sending the ATP results to a hygienist, who prepares a clearance report.


  • Marsden’s Level 3 response is designed for facilities in which occupants cannot be removed, such as high traffic public facilities or hospitals. In Level 3, Marsden uses the same disinfectants and processes as Level 2 with the addition of setting up a containment area with negative pressure and providing an onsite hygienist to perform ATP testing and oversight.
