As the time for spring cleaning and exterior maintenance approaches, you’re probably taking stock of all the things you need to do once wintertime finally ends. If your windows are looking cloudy, dirty, or streaky, you may be wondering, Can I power wash my windows? After all, power washing is a quick and effective way to clean concrete, siding, roofing, and other outdoor surfaces. Why not give your windows a quick once-over, too?

At VUE Window Cleaning, we specialize in both pressure washing and window cleaning, giving us the expertise we need to answer this all-important question. If you’re wondering whether it’s okay to power wash your windows, keep reading to learn the risks and limitations of power washing, some safer alternatives, and the role of professional window cleaning services.

What Power Washing Actually Does

Power washing uses a high pressure — typically somewhere between 1,000 and 3,000 PSI — to blast away dirt and grime. Professional power washing equipment can be even more powerful, reaching a PSI of 4,000 or more. 

Windows are more delicate than siding, concrete, or fencing, making this intense pressure not suitable for most of them. Power washing can crack the glass, force water under window seals, damage wooden frames, strip paint from the surrounding materials, and more.

So, should you power wash your windows? Probably not. But let’s take a closer look at what exactly the risks are and situations when power washing may be okay. 

Potential Risks of Power Washing Windows

The potential risks of power washing your windows include:

• Glass damage: The high pressure can cause cracks or chips in the glass. Plus, if cold water hits sun-warmed glass, it can add thermal stress to your windows and increase the risk of shattering. 
• Broken seals: When water is forced into the seals of double- or triple-pane windows, it can cause fogging, condensation, and reduced energy efficiency. 
• Water intrusion: Leaks around frames and flashing can damage drywall, trim, and insulation. If not promptly addressed, these leaks can cause significant water damage and potentially lead to mold and mildew growth. 
• Frame and screen damage: High-pressure water jets can bend aluminum window frames, tear or dislodge screens, and cause paint to peel off wooden frames.
• Safety hazards: No matter what surface you’re power washing, there’s a risk of slippery surfaces (especially in winter) and ladder or equipment mishaps. 

When Power Washing Might Be Appropriate

That being said, there are some situations where power washing your windows might be appropriate, including on commercial or specialty glass designed for higher impact or detached structures like sheds or garages.

If you decide to go this route, make sure you test a small, inconspicuous area first. Use a wide-angle nozzle and a very low PSI setting. Keep significant distance between the nozzle and the glass and avoid seams, seals, and edges. 

Better Alternatives for Cleaning Windows

There are much better ways to clean your windows, such as professional window cleaning services. Professionals use purified water systems and soft washing methods to provide streak-free glass and protect your window seals and frames. Plus, the cost of professional window cleaning is less than you’d spend repairing damage caused by pressure washing.

However, keep in mind that professional window cleaning is the safest, most effective option if you notice hard water stains or mineral buildup, oxidation on frames, or stubborn debris build-up. This is especially true if your windows are high, difficult to access, aging, or have existing seal issues. Professionals know how to remove tough stains without putting your windows — or themselves — at risk.
