Quality Assurance Program

Modern Maintenance’s Quality Assurance System is a simplistic evaluation to assist management staff in determining one thing. Is the building clean? No complex tracking systems or elaborate reporting, just a tool to determine if the cleaning staff is meeting expectations.


It is the Account Manager, Account Supervisor or Lead Workers responsibility to evaluate sample areas on a daily basis. Quality Assurance Forms are customized to each site to insure ease of use and accuracy. These forms are filed in a three ring binder to enable easy review by District Managers.


District Managers evaluate each building thoroughly on a monthly basis. They perform their own Quality Assurance Survey and compare them to the survey of the on-site personnel to insure all areas are at or above standards.


It is the Account Manager, Account Supervisor or Lead Workers responsibility to evaluate each building thoroughly on a weekly basis. These forms are compared to the daily samplings to insure areas that required attention have been corrected.


On a quarterly basis our senior management staff meets with each client to review a wide array of topics. Cleaning standards, anticipated moves and extra project work are just of few of the items covered.

Quality Assurance System

The key for any efficient quality assurance program lies with the people monitoring it. All of the electronic systems, handheld devices and “state of the art” tracking software do no good unless the employees performing the tasks are qualified to be administering the program. At Modern Maintenance we involve several layers of our experienced management team in evaluating our program to make sure we are exceeding expectations. With a senior management team that averages over 20 years of industry experience we know what clean is and how to maintain it.


Our staffing approach is simple, get the best employees and support them any way we can. Our commitment is that we will give each employee the best tools, training, and opportunities in order to enable them to make a positive difference in the environments we are cleaning.


All Modern Maintenance employees must:

  • Pass a thorough background check prior to hire
  • Be eligible to work in the United States (E-Verify)
  • Be able to read and understand English
