Why Us

The Interstate Difference

Interstate Commitment

The Interstate difference starts with commitment. Our commitment to work hard to ensure long-term satisfaction has made us a growing successful firm for over a quarter of a century.

We will develop a plan that works best for you, your site, and your budget. Every building is different, making it even more important to have a program designed to fit your specific needs. Our professional team will listen, access your needs and develop a customized plan.

Interstate’s team will provide ongoing communication with the goal of increasing your overall satisfaction. From day one, our management team will ensure a seamless transition with immediate noticeable improvements. We have dramatically helped our clients reduce their time and involvement in daily maintenance operations.

Interstate Quality Assurance Program

Our goal is to exceed your expectations, which is why we always provide a Quality Assurance Program. With this program, a representative will conduct periodic performance evaluations with the intent to improve service and reduce cost.

Interstate Team

Our uniformed staff is directly employed and trained by Interstate. We do not use subcontractors or temporary employees for any cleaning services (except high-rise window cleaning and 24/7 emergency restoration).

Our training program includes:

  • Hands on site training
  • Direct safety training programs
  • Distributor specialist training
  • DVD training program

For the protection of your employees, tenants and guest, Interstate employees follow OSHA requirements and are responsible for reporting any unsafe conditions to a building representative.

Interstate Products and Equipment

In our ongoing effort to help increase efficiency and reduce costs, we provide the following:

  • A regularly scheduled assessment program, including weekly equipment inspections and quarterly consumable assessments.
  • A janitorial closet organization program.
  • Our chemical dilution method and on-site Safety Data Sheets (SDS) which increase safety for your staff and visitors.
Professional, Passionate, Committed
Interstate Maintenance Corporation is “The Company That Cares”


“All in all, this is the best crew we’ve ever had and I would be very upset to see them leave. Interstate employees are good workers that want to do a good job, and THAT is very hard to find. And I don’t have to spend any of my time on cleaning issues, which has never been the case before.”
Laura D., Office Manager
