How Often to Wash Exterior Windows: A Guide to Keeping Your Windows Sparkling Clean

How often you should wash exterior windows depends on various factors including your location, weather conditions, building material, and proximity to pollutants like traffic or trees. Generally, professional window cleaners recommend cleaning exterior windows at least twice a year—once in the spring and once in the fall. However, if you live in a city with heavy air pollution, near the ocean with salt spray, or in an area prone to pollen and dust, quarterly cleaning may be necessary to maintain the best appearance and longevity of your glass. For homes surrounded by trees, sap, bird droppings, and leaves can also accumulate quickly, warranting more frequent cleaning.

As a designer, I see window cleanliness not just as a matter of hygiene but as a crucial element for enhancing natural light flow and visual connection between interiors and exteriors. Clean windows can drastically improve your indoor ambiance by maximizing sunlight, making your space feel more inviting and refreshing. When planning your home maintenance schedule, consider integrating exterior window cleaning as part of your broader approach to maintaining an appealing and functional living environment. Innovative tools like a home designer solution can help you visualize the transformative effect that increased natural light and clean windows have on your interiors, ensuring your design vision is realized in practice.

Tips 1:

Schedule window cleaning after major weather events like storms or heavy pollen seasons for optimal clarity. Use mild cleaners and soft brushes to prevent scratching, especially if you have specialty glass. And always check for hard water stains or mineral buildup, which may require specialized products for removal.
