Look up.
Go ahead – tilt your head back and really look. See those massive glass towers that shape the skyline? Ever wondered how all that glass stays clean? Not just the stuff you can see from the street – but right up there, 40, 50, even 80 storeys high.
It’s easy to forget. We walk by these buildings every day. We notice the shiny glass, the reflections, the way the clouds bounce off the windows… but we don’t think about the people whose job it is to keep that glass spotless.
This isn’t the kind of window cleaning that happens with a step ladder and a spray bottle. This is a different world — a world of ropes, harnesses, cradles, wind, heights… and a whole lot of trust in both skill and equipment.
Welcome to the world of professional commercial high rise window cleaning. Quiet, precise, often invisible — but absolutely essential. Here’s a peek behind the scenes at how it actually gets done.
The First Step — Planning Every Move
It all starts long before anyone even leaves the ground. Cleaning a commercial high-rise window is not a “grab a bucket and go” kind of job. It begins with site assessments — looking at building designs, anchor points, wind conditions, and access restrictions.
Every building is different. Some have built-in systems like BMUs (Building Maintenance Units) — the mechanical cradles you see gliding down the sides. Others rely on industrial rope access where cleaners literally rappel down the building like climbers.
Safety plans are drafted. Gear is checked. And only then does the team suit up.
Rope Access — The Art of Dangling With Purpose
For buildings without cradles, rope access is often the method of choice. Cleaners from a reliable window cleaning company wear full-body harnesses connected to industrial-strength ropes secured to certified anchor points on the rooftop.
It’s not as simple as lowering yourself down and scrubbing away. Each cleaner works with two ropes — a primary rope for working and a backup rope for safety. The setup allows them to control their descent, stop mid-air, and move sideways along the building’s surface.
This method is highly efficient and surprisingly gentle on the building facade since it doesn’t require heavy equipment. But it’s only for those who have serious training and a good head for heights.
The Cradle System — A Moving Balcony in the Sky
If you’ve seen platforms that look like mini scaffolds hanging on cables, that’s a cradle system. These are motorised units designed for high rises with more complex exteriors or larger surface areas.
Cradles offer a bit more comfort — workers can stand, move equipment around, and tackle wider sections at a time. But they also come with their own checks and balances. The system needs regular maintenance, inspections, and skilled operators to function safely.
Tools of the Trade — More Than a Squeegee
Sure, there’s the classic squeegee — still one of the most reliable tools out there. But high rise window cleaning also uses pure water systems (deionised water that leaves zero streaks), telescopic poles for lower levels, eco-friendly detergents, and specialised scrapers for removing stubborn grime or mineral deposits.
The goal isn’t just clean-looking glass — it’s about extending the life of the windows. Dirt, pollution, bird droppings, and salty air (especially in Sydney) can slowly degrade the surface if left too long.
The Invisible Challenges — Wind, Weather & Gravity
Even the most experienced cleaner can’t fight nature. Strong winds, sudden rain, or even extreme heat can halt a job midway. Winds at 40 metres can feel very different than what’s happening at street level. Safety always comes first — if conditions aren’t right, the job waits.
It’s Not Just About Aesthetics — It’s Building Care
Clean windows aren’t just about looking good (though they help!). They allow more natural light into offices, reduce long-term glass damage, and maintain the building’s professional appearance. For commercial tenants, that can even affect mood, productivity, and client impressions.
Final Thoughts
Commercial high rise window cleaning is a blend of precision, courage, and technical skill. Whether it’s a sleek corporate tower or a heritage building in the city, keeping those windows spotless takes a trained team that knows how to balance safety, efficiency, and care.
