Windows are important to any home or business as they provide natural light and ventilation. They are the perceptible reflection of the inhabitants’ state of mind.

Clear and spotless windows can improve your home’s and business exterior’s appearance and promote a pleasant and healthy indoor atmosphere.

However, windows can become dirty over time, affecting their function and aesthetic appeal. Therefore, cleaning your windows is essential to maintain their longevity and ensure that they work effectively.

How often should you clean your windows?

For Homeowners

Usually, dirt, dust, and debris can accumulate on your windows over a certain period of time, affecting their clarity and reducing their lifespan.

Thus, the general recommendation for residential window cleaning indicates that you should clean your windows at least twice a year.

Seasonal changes can also impact the cleanliness of your windows, with the rainy season and winter being the prime time for windows to become dirty. Therefore, cleaning your windows by the end of each season is also important.

Business Owners

Commercial window cleaning is required to maintain a positive working environment and create a good first impression. Therefore, business owners must clean their windows at least once a month.

On the other hand, if your business is located in an area with high traffic, you may need to clean your windows more often to remove fingerprints, smudges, and other dirt accumulating on your windows.
