Introduction

Pressure washing windows may seem like a quick and effective method for cleaning glass, but it comes with significant risks that many businesses may overlook. While the high-pressure streams of water can remove dirt and grime from surfaces, they can also cause irreversible damage to windows, frames, and seals, leading to costly repairs and replacements. For businesses looking to maintain their premises in pristine condition, understanding the dangers of pressure washing windows is crucial. This article explores the potential hazards of pressure washing, why it is best left to professionals, and how businesses can ensure their windows are cleaned safely and effectively.

The Dangers of Pressure Washing Windows

Pressure washing is a widely-used cleaning technique for exterior surfaces such as driveways, patios, and building facades, primarily due to its speed and power. It involves the use of high-pressure water jets to blast away dirt, grime, algae, and other unwanted materials. However, when it comes to windows, using a pressure washer can be a hazardous approach. While the idea of using a pressure washer to clean windows might seem like an effective solution for businesses, the risks involved often outweigh the benefits. Below are the primary dangers of pressure washing windows:

1. Window Damage

The most apparent and immediate danger of pressure washing windows is the potential for physical damage to the glass itself. Windows, especially modern ones, are designed with a certain level of resilience, but they are still fragile and vulnerable to impact from high-pressure water streams.

When a pressure washer is directed at the window, the force of the water can cause cracks, chips, or even breakage, particularly if the nozzle is too close to the glass or the pressure is too high. Even small cracks can become larger over time, leading to compromised structural integrity of the window. This is especially true for older windows or those with existing hairline fractures that may go unnoticed until the pressure washing exacerbates the issue.

Furthermore, repeated pressure washing can weaken the glass over time. The impact of the water jets, while it may not cause immediate damage, can slowly degrade the surface of the glass, making it more prone to future cracking or shattering. Unlike surfaces such as brick or concrete, which can withstand pressure washing without major issues, windows are far more vulnerable to such treatment, making it a risky proposition for businesses.

2. Frame and Seal Damage

In addition to the potential harm to the glass itself, pressure washing windows can also cause significant damage to the frames and seals. Window frames are typically made from materials such as wood, aluminium, or vinyl, all of which are vulnerable to water infiltration when subjected to high-pressure jets. The water can seep into the frame, weakening the structure and causing it to warp or degrade over time.

Furthermore, the force of the pressure washer can dislodge or loosen the sealant around the window. The sealant serves to keep the window airtight and waterproof, protecting the building from drafts, moisture, and other environmental factors. If the sealant is compromised, water can seep through the window frame, causing leaks and resulting in further water damage to the surrounding building materials. Over time, this can lead to more significant problems, including mould growth, structural damage, and a reduction in the energy efficiency of the building.

For businesses that rely on maintaining a professional and secure environment, damaged seals and frames can result in an increased need for repairs, escalating maintenance costs, and a diminished aesthetic appearance of the property.

3. Risk of Water Intrusion

One of the most concerning dangers of pressure washing windows is the risk of water intrusion into the building itself. If the pressure washer is not carefully aimed or the window is not sealed properly, the water can be forced into the gaps between the window and the building’s exterior walls.

Water intrusion can lead to a range of problems, including dampness inside the building, the growth of mould and mildew, and even electrical hazards if the water comes into contact with wiring or sensitive equipment. For businesses with valuable machinery, inventory, or electronic systems, the consequences of water intrusion can be catastrophic. Mould, in particular, is not only harmful to the health of employees or clients but can also cause long-term damage to the interior structure of the building.

While businesses may attempt to mitigate these risks by applying sealants, there is always a chance that water will find its way in, especially if the pressure washing is done too aggressively. This makes pressure washing an unsuitable option for cleaning windows, particularly in commercial properties that house sensitive or irreplaceable equipment.

4. Safety Concerns

Pressure washing windows, especially those located on upper floors or hard-to-reach areas, presents significant safety risks for the person performing the task. The powerful jets of water can cause the operator to lose balance or footing, particularly if the surface beneath them is wet or slippery. This increases the risk of slips, trips, and falls, especially when working from a ladder or scaffolding.

For high-rise buildings or multi-story commercial properties, pressure washing windows can be especially dangerous without proper safety equipment such as harnesses or scaffolding. A lack of proper training can lead to injuries, which not only pose a threat to the safety of workers but can also result in costly insurance claims, liability issues, and potential legal ramifications for businesses. This is another reason why professional window cleaning services are preferred, as trained technicians use the proper safety equipment and techniques to mitigate these risks.

5. Ineffective Cleaning

Although pressure washing is often praised for its efficiency in cleaning, it is not always effective when it comes to windows. While high-pressure water jets may remove surface dirt and debris, they are less effective at addressing the more stubborn contaminants that often accumulate on windows, such as bird droppings, tree sap, or hard water stains.

Pressure washing also tends to spread dirt and debris around, potentially creating a bigger mess. The force of the water may drive dirt into hard-to-reach areas or even cause dirt to accumulate on surrounding surfaces, such as the building’s walls or landscaping, which now requires additional cleaning. Moreover, the method may not effectively remove smudges or fingerprints that accumulate on glass surfaces over time, leaving windows looking streaky or even dirtier after cleaning.

For businesses aiming to present a professional and polished image, the results of pressure washing windows may fall short. The goal should be a thorough, streak-free clean, which is far more effectively achieved through traditional cleaning methods or professional window cleaning services.

6. High Costs of Repairs

The potential for damage caused by pressure washing windows can lead to significant repair costs. If pressure washing causes a crack or chip in the glass, the only option may be to replace the entire window. This can be expensive, especially if multiple windows across the property are affected. Additionally, damage to window frames, seals, or other surrounding areas may require costly repairs or replacements, further escalating the financial burden on the business.

Furthermore, water intrusion resulting from sealant damage can lead to additional expenses. Water damage to the interior of the building, including walls, ceilings, and floors, can require expensive restoration work. Mould remediation is another costly process, particularly for businesses with valuable equipment or sensitive materials that may have been exposed to moisture.

The repair costs associated with pressure washing windows can quickly outweigh the initial savings of using a pressure washer as a cleaning method. Investing in professional window cleaning services not only ensures the safety of the windows but also prevents the need for expensive repairs.

7. Long-Term Building Maintenance Issues

The long-term effects of pressure washing on windows and the surrounding building materials can lead to premature wear and tear. The repetitive use of high-pressure water can degrade window seals, paint, and even the structure of the frames, causing them to deteriorate faster than they would under normal conditions. Over time, this can result in increased maintenance costs and a need for more frequent repairs.

In addition to the damage caused to the windows themselves, the impact of pressure washing on the building’s exterior can result in aesthetic issues. Pressure washing can strip away protective coatings on windows or even damage the paint on window frames, making the building look older and less well-maintained. For businesses aiming to create a positive impression on clients and customers, maintaining the property’s aesthetic appeal is vital. This is another reason why pressure washing should be avoided as a method for cleaning windows.
