How to Clean Glass Windows in High Rise Buildings

Cleaning glass windows in high rise buildings is a unique challenge due to height, safety and specialised equipment. Whether you’re a professional window cleaner or a building manager wanting to understand the process this guide will walk you through the techniques and safety measures.

Safety First: The Foundation of High Rise Window Cleaning

Before any cleaning starts safety protocols must be put in place:

• All personnel must be properly trained and certified to work at heights
• Weather conditions must be monitored (don’t clean during high winds or storms)
• Equipment inspection before each job
• Clear communication between ground teams and cleaning crews
• Proper permits and insurance in place

Equipment Essentials

The right tools make all the difference in high rise window cleaning:

• Suspended scaffolding or building maintenance units (BMUs)
• Fall protection systems (harnesses, anchors and lifelines)
• Extension poles with squeegees and washer sleeves
• Specialized cleaning solutions for glass
• Microfiber cloths and lint-free towels
• Water-fed pole systems for lower floors (up to 60 feet)
• Drones for inspection (increasingly common)

Professional Cleaning Methods

1. Traditional Suspended Scaffold Method

This old school approach involves workers on a suspended platform:

1. Position the scaffold at the top (usually top floor)
2. Apply cleaning solution to the glass
3. Remove dirt with the squeegee in overlapping S or Z patterns
4. Wipe edges with a cloth to prevent streaks
5. Work your way down the building façade

2. Rope Access Method

For buildings with complex architecture or limited anchor points:

1. Technicians rappel down the building with industrial ropes
2. Equipment is carried in specialized bags attached to the harness
3. The cleaning process is the same as the scaffold method but requires more skill
4. Minimal disruption to building occupants

3. Water-Fed Pole Systems

For lower floors or as a supplementary method:

1. Purified water is pumped through extendable poles
2. Brush attachments dislodge dirt
3. Pure water leaves no residue when it dries
4. Can reach up to 60 feet from ground level

Environmental Considerations

Modern high rise window cleaning is all about sustainability:

• Eco-friendly, biodegradable cleaning solutions* Water conservation techniques (recirculation systems)
• Clean during optimal weather to reduce energy use
• Use purified water to eliminate chemical runoff

Maintenance Schedule

Regular cleaning keeps the building looking good and windows last longer:

• Urban areas: Quarterly cleaning
• Suburban/rural: Semi-annual cleaning
• Coastal buildings (salt exposure): Bi-monthly cleaning
• Post-construction: Special intensive cleaning required

Challenges and Solutions

High rise window cleaning has its own set of challenges:

• Challenge: Water spotting on sunny days
  Solution: Clean early morning or cloudy days
  
• Challenge: Bird droppings and mineral deposits
  Solution: Special enzyme cleaners and scrapers for glass
  
• Challenge: Window gaskets and frame cleaning
  Solution: Separate cleaning pass with the right solutions

Professional vs. DIY

For high rise buildings professional services are highly recommended because:

• Safety requirements and liability
• Specialized equipment costs
• Training and certification
• Insurance
• Efficiency and results

Conclusion

Cleaning glass windows in high rise buildings requires specialized equipment, training and strict adherence to safety protocols. The investment in professional services means not only sparkly windows but building preservation and occupant safety. With proper planning and regular maintenance your building’s windows will remain a feature of the cityscape for years to come.
