How Often Should You Clean Your Windows?

There's nothing like a clear, sunny day in Washington, until your windows turn that golden light into a smudged, streaky mess. Dirty windows don't just block your view. They make your whole home feel dim, dusty, and a little forgotten.

At Wonderboy, we believe clean windows aren't just about appearances. They're about pride in your space, the feel of your home, and the way natural light changes your mood. So how often should you clean them? Let's break it down.

What affects how often you should clean?

There's no universal answer, but these factors can help guide your window cleaning routine:

Weather & environment

Living in the Pacific Northwest means dealing with rain, wind, pollen, and dust. Homes near trees, roads, or ongoing construction collect grime faster, especially on lower-level windows.

Kids & pets

Fingerprints, nose prints, and accidental splashes build up quickly, especially in high-traffic areas like living rooms, kitchens, and sliding glass doors.

Type of windows

Older wood-framed windows or single-pane glass often need more frequent attention to prevent long-term damage from moisture, dirt, or mildew.

Air quality & allergens

Dust, pollen, and pollution settle on your glass, sills, and screens, and affect the air you breathe inside your home.

The ideal window cleaning schedule

Here's what we recommend for most homes in Snohomish County and surrounding areas:

• Exterior windows: 3× per year (spring, summer, and fall)
• Interior windows: 2× per year, or more if little hands or paws press against the glass
• Screens & tracks: at least once a year, because dust and pollen love to collect there
• After storms or heavy pollen season: consider a touch-up to restore clarity

Wonderboy also offers the Protective Plan, so your home stays shining without you needing to remember when it's time. We handle the schedule; you enjoy the view.

Warning signs your windows need attention

• A noticeable drop in natural light
• Visible streaks, water spots, or grime
• Dust or allergens drifting in through open windows
• You're prepping your home for guests, events, or a listing

Why regular window cleaning matters

• Prevent permanent damage: mineral deposits and hard water stains can etch glass over time.
• Boost curb appeal: sparkling windows make your home look well-kept and welcoming.
• Protect your investment: clean tracks and screens extend the life of your windows.
• Enjoy more daylight: natural light makes your space feel bigger and brighter.
