The Custodial Services' team keeps the university looking its best through their cleaning and sanitization.
McMaster currently employs more than 220 custodians across campus, including within Housing & Conference Services. We pride ourselves on our high standards for cleaning and our commitment to the health and well-being of our entire campus community.
The McMaster Period Equity Project aims to provide free menstrual products to students, staff, and faculty through bins and dispensers in select washrooms on McMaster’s main campus.
How often should you expect your office to be cleaned? Garbage removed from classrooms? Floors washed at building entrances? You can find your answers in our cleaning standards and frequencies page.
Our custodial teams contribute to a brighter world by keeping our spaces clean and comfortable, supporting the health and well-being of our overall community.
Our amazing custodians stepped up during the pandemic to enhance the cleaning standards of our spaces, supporting our ability to continue teaching and learning in a safe environment.
Spot something that needs cleaning? Submit a cleaning request for dirty surfaces, slippery floors, unclean washrooms and more.
