How Often Should You Clean Exterior Windows?

Fast Answer

Most homes need exterior window cleaning twice per year. In high-dust or pollen-heavy areas like rural South Carolina, more frequent cleanings may be necessary to maintain clarity and avoid long-term damage.

What Affects Cleaning Frequency?

– Pollen count

– Nearby construction or gravel roads

– Landscaping close to windows

– Irrigation overspray

– Amount of tree cover

Can Dirty Windows Be Damaged?

Yes—debris like dust, bird droppings, and water spots can:

– Scratch the glass

– Break down the UV coating

– Create mineral buildup that’s nearly impossible to remove

What’s the Best Method?

Professional window cleaning is safer and more effective because:

– We use deionized water that dries without spots

– Brushes and poles reach second-story windows without ladders

– We clean tracks, sills, and screens—not just glass

How Can You Tell It’s Time?

– Your windows look hazy even after it rains

– You see cobwebs, pollen, or bugs stuck in the corners

– Rooms feel darker than they used to

– You can write your name in the grime

Is Inside or Outside More Important?

Exterior windows collect the majority of debris, especially from storms, pollen, and landscaping dust. Indoor cleaning is still helpful, but less frequent.
