If you’re wondering how often you should schedule professional window washing, you’re not alone. At King of Kings Window Cleaning LLC, we hear this question often—and the answer depends on where you live, what surrounds your home, and the changing seasons here in Whatcom & Skagit County, including Bellingham, Oak Harbor, Bow, Mount Vernon, Burlington, Everson, Ferndale and Sudden Valley.
In this guide, we’ll break down how often to clean your windows, why it matters, and how we help protect your glass and your view all year long.
Spring: The Season of Renewal
Spring is one of the best times to clean your windows. Rain, wind, and pollen from winter storms leave glass streaked, foggy, and covered in grime.
- Pollen buildup
- Tree sap and dust
- Bug marks and rain residue
Recommended Cleaning: Exterior and interior windows + screens + tracks Frequency: Once in early spring (March–May)
Summer: Dust, Bugs, and Sunlight Stains
While summer brings beautiful weather, it also brings more dust, insects, and hard water spotting from sprinkler overspray. If your home has large windows that face the sun, buildup becomes even more noticeable.
- Exterior grime is most visible in direct sunlight
- Frequent entertaining? Clean windows impress guests
- Screens can clog with pollen, reducing airflow

Fall: Time to Prep for Rainy Season
Falling leaves, windstorms, and early rains start affecting your windows in early fall. It’s important to wash them before residue becomes harder to remove over winter.
- Gutter runoff can splash windows with debris
- Skylights collect grime quickly in stormy weather
- Moss spores can land near frames and tracks

Winter: Keep the View Bright
We clean windows year-round, including winter when the Northwest gets gloomy. Clean glass helps bring more natural light into your home when you need it most.
- Winter sun through dirty windows reduces indoor brightness
- Clean tracks and frames prevent mold buildup
- Storm season can cause heavy debris on skylights

What Impacts Window Cleaning Frequency?
- Location: Homes near farmland, trees, or busy roads need more frequent cleaning.
- Pets and Kids: Fingerprints, paw prints, and smudges build up fast indoors.
- Rain & Wind: More exposure equals more debris on your glass.
