Pressure washing is a popular method for cleaning various outdoor surfaces, such as driveways, decks, and siding. However, when it comes to cleaning windows, especially double-pane windows, concerns arise regarding the potential damage that might be caused by pressure washing. In this article, we will explore whether pressure washing can harm your double-pane windows and discuss some precautionary measures to protect them during cleaning.
Understanding Double-Pane Windows
Before delving into the effects of pressure washing on double-pane windows, it is essential to understand what they are and how they function. Double-pane windows consist of two panes of glass separated by a spacer, which creates an insulating air pocket. This design helps improve energy efficiency by reducing heat transfer and providing better soundproofing.
Potential Damage from Pressure Washing
While pressure washing is a highly effective technique for cleaning many surfaces, there are inherent risks when it comes to applying high-pressure water to delicate structures like double-pane windows. Some potential damages include:
- Cracked or Broken Glass: The excessive force applied during pressure washing can cause the glass panes to crack or even break, rendering the window ineffective and necessitating costly repairs or replacement.
- Damaged Weather Stripping: The strong water pressure from a pressure washer might dislodge or damage the weather stripping around the window frame. This can lead to compromised insulation and increased energy costs.
- Leaking Windows: Double-pane windows are designed to be airtight to achieve maximum energy efficiency. However, pressure washing can force water through small gaps or cracks in the window seals, leading to moisture buildup between the glass panes. This can result in foggy windows and decreased insulation properties.
Precautionary Measures
To avoid potential damage to your double-pane windows when pressure washing your home’s exterior, consider taking the following precautionary measures:
- Adjust the Pressure: Lower the pressure on your pressure washer to minimize the risk of causing damage. Using a lower pressure setting will reduce the force applied to the windows while still effectively cleaning the surrounding surfaces.
- Increase the Distance: Maintain a safe distance between the pressure washer nozzle and the window surface. This will help decrease the impact force and minimize the risk of cracks or breaks.
- Protect the Windows: Cover the windows with plastic or secure waterproof covers before pressure washing nearby areas. This will provide an added layer of protection and help prevent water from penetrating the window seals.
- Consult Professionals: When in doubt, it is best to consult professional window cleaners who have experience in pressure washing double-pane windows. They will have the necessary skills and equipment to perform the task effectively without causing damage.
While pressure washing can be an efficient cleaning method for many outdoor surfaces, it is essential to use caution when cleaning double-pane windows. The strong force of water from a pressure washer can potentially crack or break the glass, damage the weather stripping, or cause window seals to leak. By adjusting the pressure, increasing the distance, and protecting the windows, you can mitigate these risks and ensure that your double-pane windows remain in perfect condition. When in doubt, it is always wise to consult professionals who specialize in pressure washing double-pane windows to ensure a safe and effective cleaning process.
