Building Maintenance Units FAQs
A BMU is a permanently installed access system used to safely carry out external building maintenance, window cleaning, and façade repairs on high-rise properties. BMUs can range from simple manual systems to fully automated telescopic units, tailored to each building’s design and access needs.
BMUs provide a safe and reliable way to access building exteriors for window cleaning, façade maintenance, and inspections. Without them, high-rise properties would face significant safety risks and higher long-term maintenance costs.
BMUs should be maintained according to a planned preventative maintenance schedule — typically at least twice a year, or more frequently depending on usage and manufacturer recommendations. Preventative servicing improves system reliability, reduces downtime, and extends equipment lifespan.
