How can our customers be sure of high quality results and efficiency? At Guam Cleaning Masters (GCM) we believe that we maintain a building for the health of its occupants. We are the building’s guardians and this is a task we take very seriously. 

We are more than just cleaners. We are healthcare providers! We hold ourselves to the highest possible levels of cleanliness. The only way to achieve this is to have a comprehensive quality control program in place. 

At GCM we achieve this by using the latest technologies in conjunction with visual and biological testing to ensure your building is being kept at the highest standards.

Take biological testing, for example:

Some areas may look clean but still carry huge amounts of infectious bacteria, which is why we have introduced ATP Testing as part of our quality control system. 

This process involves rapidly measuring actively growing microorganisms through the detection of adensosine triphosphate or ATP and shows the amount of microorganisms present on a surface.
