What Is Pressure Washing?

Before we dive into the details of pressure washing windows, it’s essential to understand the technique itself. 

Put simply, pressure washing is a powerful cleaning method that utilises high-pressure water sprays to eliminate dirt, grime, and other debris from various surfaces. However, the exact method and pressure used can vary depending on the surface being cleaned and the level of grime or build-up present.

Pressure washing can be done using traditional pressure washing, which involves using high pressure and hot water, or a gentler approach known as soft washing. 

Soft washing uses a lower pressure setting and a specialised cleaning solution to clean delicate surfaces, such as roofs, stucco, and painted surfaces. This method is ideal for removing mildew, mould, and algae from surfaces without causing damage.

The Pros & Cons Of Pressure Washing Your Windows

Pressure washing windows can have both pros and cons, which are important to consider before deciding whether or not to use this method. Here are some of the key benefits and drawbacks of pressure-washing windows:

Benefits & Advantages

1. Quick & Effective Cleaning

 Pressure washing is an efficient and effective way to remove dirt, grime, and mould from windows. The high-powered water spray can quickly blast away even the toughest build-up, leaving your windows looking sparkling clean in no time.

2. Saves Time

Hand washing windows can be a time-consuming and labour-intensive task. Pressure washing, on the other hand, can be a much quicker and more efficient alternative, especially for larger properties with a lot of windows to clean.

3. Reach Hard To Reach areas

With the help of specialised attachments and wands, pressure washing can reach high areas that are difficult to access by hand. This makes it an ideal solution for tall buildings or multi-story homes.

4. Eco-friendly cleaning

Pressure washing does not require the use of harsh chemicals or cleaning agents for effective results, making it an environmentally friendly option for cleaning your windows.

5. Improves the Appearance of Your Property

Clean windows have a significant impact on the overall look of your property. Pressure washing your windows can ensure that they are always looking their best, boosting your home’s curb appeal and giving it a polished and well-maintained appearance!

Cons & Considerations

1. Can Cause Leaks

Improper use of a pressure washer can damage the window sealant and surrounding frame, leading to leaks and other issues. That’s why it’s essential to choose the appropriate pressure setting and use the right technique to avoid damaging the window structure.

2. Damage Glass

High-pressure water, if not used correctly, can cause cracks or chips in the glass or even break the glass entirely. To prevent this from happening, it’s important to avoid directing the water spray at a very close distance from the surface and use lower pressure settings for more delicate windows.

3. Not Suitable For All Window Types

Pressure washing is not suitable for all types of windows, such as older or more delicate windows. If your windows are not suitable for pressure washing, consider alternative cleaning methods, such as hand washing or soft washing.

When it comes to pressure washing windows, there are several tips that can help ensure clean and clear windows. Here are a few to keep in mind:

Assess The Condition of Your Windows

Before starting to pressure wash your windows, it is essential to assess their condition. If there any cracks, chips, or other damage, it may not be safe to pressure wash them. In such cases, it is better to use other cleaning methods or hand washing or repair the windows before cleaning. Using a pressure washer on damaged windows can cause more harm than good and potentially lead to costly repairs or replacements!

Prepare The Work Area

It is important to take a few steps to protect surrounding areas, before pressure washing can begin. Pressure washers are prone to spraying water and debris, so it’s a good idea to cover any nearby plants or objects with a tarp or plastic sheeting.

Additionally, it is important to clear the area of any furniture or obstacles that could be in the way during the cleaning process. This will help ensure that the pressure washer can be used safely and effectively without causing accidents or damage.

Start At The Top And Work Downwards

Starting at the top of the window and working downwards is an important technique to remember when pressure washing windows. This method ensures that any excess water and debris flows downward, preventing it from getting underneath the window or into the sealant. Similalrly, starting at the top allows you to clean any areas that may be particularly dirty or covered in grime first, which will save time and effort in the long run.

Avoid Direct Spray On The Edges Or Seals

Direct pressure on the edges or seals of the window can cause damage or leaks, so it’s important to avoid direct spray on these areas. Hand washing can be an effective way to clean edges and seals while avoiding damage.

Remove Excess Water From The Sills

It is essential to remove any remaining water from the sills and glass. This step will help prevent water from pooling and causing damage, promoting the growth of mould or mildew as well as prevent streaks and ensure a sparkling clean finish.
