The Basics of High-Rise Window Cleaning

Cleaning windows in highrise buildings is different from residential or low-rise building cleaning. 

The height of the building presents challenges such as working at elevated positions, dealing with weather conditions, and ensuring safety. 

Deep cleaning of high rise windows also involves removing deep stains and air pollution buildup requiring specialized methods and cleaning solutions to restore the glass to its clear pristine state.

Safety First: Ensure Proper Safety Measures

Before starting any window cleaning in a high-rise building, the safety of the workers is the top priority. 

Workers must be equipped with personal protective equipment (PPE) such as safety harnesses, helmets, gloves, and appropriate footwear. 

These protective measures help minimize the risks of accidents and injuries while working at great heights.

Assess the Equipment Needed

Cleaning windows in high rise buildings requires specific tools that are not typically used for regular window cleaning. Below is a list of essential equipment required to clean windows in such a setting:

Rope Access System

This allows window cleaners to access high windows safely. The rope system is anchored at the top of the building and allows workers to descend and ascend the building’s facade while remaining securely fastened.

Aerial Work Platforms (AWP)

Also known as cherry pickers or scaffolding, these platforms provide access to the windows of high rise buildings. The workers can be elevated to the desired height to clean the windows efficiently.

Water Fed Pole Systems

These systems are designed to clean windows from the ground up. The water fed pole system includes a long telescopic pole with water flowing through it, reaching high-rise windows without the need for ladders or scaffolding.

Squeegees and Scrubbers

A traditional cleaning tool, squeegees are used to wipe away cleaning solutions and water, while scrubbers are used to apply the cleaning solution onto the windows.

Specialized Cleaning Solutions

High-rise window cleaners often use professional-grade cleaning solutions that are tough on dirt but gentle on the glass, ensuring a streak-free finish.

Harness and Lanyard

For those using rope access, the harness and lanyard are essential safety equipment to secure the worker to the building structure.

Prepare the Cleaning Solution

The cleaning solution is one of the most important aspects of high rise window cleaning. A mixture of warm water and mild detergent is commonly used. 

Professionals may also use specialized window cleaning solutions that are formulated to remove tough dirt and grime without damaging the glass.

Start Cleaning from Top to Bottom

When cleaning high-rise windows, start at the top to avoid drips on clean windows. First scrub the window gently with a soft bristled brush to remove dirt. 

Then, use a squeegee to wipe off the cleaning solution in a top to bottom or side-to-side motion. After each swipe, clean the squeegee blade to prevent streaks.

Inspect the Window for Streaks or Residues

Once the initial cleaning process is done, it’s crucial to inspect the window for any missed spots or streaks. Streaks can often form due to soap residue or improper wiping techniques. If necessary, go over the window with a clean cloth or microfiber towel to ensure a spotless finish.

Safety Protocols During the Cleaning Process

Cleaning windows at heights means that safety is paramount at all times. For those using aerial work platforms or rope access systems, ensuring that all equipment is in good working condition and properly secured is essential. 

Additionally, all workers should have appropriate training to work at heights and use the equipment safely.

How Often Do High-Rise Windows Get Washed?

The frequency of high rise window cleaning depends on factors like location, climate, and aesthetic needs. Generally, windows should be cleaned every 2 to 3 months, but areas with high pollution or coastal air may require monthly cleaning. 

Interior windows are cleaned less often but are important for offices and commercial spaces. High profile buildings may need more frequent cleaning, while less exposed buildings can be cleaned every 3 to 6 months.

What Do Window Cleaners Use on High-Rise Buildings?

Window cleaners use specialized equipment designed for cleaning windows at great heights. Below is an overview of the essential tools:

Rope Access Systems

Rope access systems are often used by professional window cleaners working in tall buildings. 

This system involves anchoring ropes to a secure structure at the top of the building, allowing workers to descend safely and clean the windows from the outside. 

Rope access is commonly used for cleaning buildings with heights that do not accommodate aerial platforms.

Aerial Work Platforms

These platforms, including scaffolding and cherry pickers, allow workers to be elevated to the window level and clean from the platform. AWP systems are often used for buildings that are difficult to access via ropes.

Water Fed Pole Systems

These systems use telescoping poles to clean windows from the ground level. The poles are equipped with brushes and a water source that helps remove dirt and grime from the windows. Water fed poles are especially useful for cleaning windows on lower floors or where aerial platforms or ropes cannot be used.

Squeegees and Scrubbers

These are the traditional tools used for window cleaning. The scrubbers are used to apply the cleaning solution, and the squeegee is used to wipe off the excess water and cleaning solution, leaving the glass streak free.

Professional Cleaning Solutions

Professional grade window cleaning solutions are formulated to remove stubborn dirt stains and grime from windows without damaging the glass. These solutions are often concentrated and need to be mixed with water before use.

Conclusion

Cleaning windows in high rise buildings is a specialized job that requires a combination of skill equipment, and safety measures. 

The process involves using high quality tools like squeegees scrubbers, and water fed poles, as well as safety equipment such as harnesses and ropes. 

High rise windows should be cleaned regularly typically every 2 to 3 months, but more frequent cleaning may be needed based on the building’s location and purpose.

By following the proper techniques and using the right equipment window cleaners can ensure that high rise windows remain spotless contributing to the building’s overall aesthetic and maintaining a high standard of cleanliness.
