Customer Support

Nothing is more frustrating than calling the janitorial services company you are paying your money to, only to be treated like you are an annoyance that must be dealt with as briefly as possible. We never forget that it is our customers that keep us in operation, and we are truly grateful for your business. Please don’t hesitate to call with any questions or concerns that you may have.

Our Quality Control program enables us to satisfy your expectations in the most productive and cost-effective manner possible. We do this by involving our janitors in the process, measuring quality, and communicating results. Our program improves our janitors’ efforts and returns increased value to our customers. We do this by:

  • On-site communication log books
  • Quality control inspections
  • Complete janitor participation in the Quality Control process, customizing our program to fit your needs
