How Often Should You Clean Your Windows?

Published: January 15, 2025 | By Window Worx

One of the most common questions we hear from homeowners in Waukee and across the Des Moines metro is: "How often should I have my windows professionally cleaned?"

The answer depends on several factors — but for most homes, 2-3 times per year is the sweet spot. Here's a breakdown to help you decide what's right for your home.

The General Recommendation

For the average suburban home in Central Iowa, we recommend professional window cleaning twice a year: once in the spring and once in the fall.

• Spring cleaning (April-May): Removes winter grime, salt residue, and the first wave of spring pollen
• Fall cleaning (September-October): Clears summer dust, pollen, cobwebs, and prepares windows for winter

When You Might Need More Frequent Cleaning

Some homes benefit from quarterly (4 times per year) or even monthly cleaning:

• Homes near busy roads: More road dust and traffic grime accumulates on windows
• New construction areas: Construction dust can settle on windows quickly
• Homes surrounded by trees: Tree sap, pollen, bird droppings, and debris require more frequent attention
• Homes with allergies: Clean windows reduce indoor allergens like pollen and mold
• For sale or open houses: Sparkling windows dramatically improve curb appeal

Signs Your Windows Need Cleaning

Not sure if it's time? Look for these telltale signs:

• Windows look hazy or foggy even on sunny days
• Visible dirt, dust, or grime buildup on glass or frames
• Water spots or hard water stains that won't wipe off
• Cobwebs around window frames and corners
• Screens are visibly dirty or clogged with debris
• You can't remember the last time they were cleaned!

What About Interior vs. Exterior?

Exterior windows typically get dirtier faster due to weather, pollen, and environmental factors. Interior windows stay cleaner longer but can accumulate dust, fingerprints (especially with kids or pets), and cooking grease in the kitchen. Most homeowners opt to clean both interior and exterior at the same time for the best results and best value.

Iowa-Specific Considerations

Living in Iowa means dealing with all four seasons — and each one affects your windows differently:

• Winter: Salt spray from roads, snow residue, and frozen condensation
• Spring: Heavy pollen (the "green dust" that covers everything), spring rains leaving spots
• Summer: Dust, bugs, bird droppings, and hard water spots from sprinklers
• Fall: Leaves, cobwebs, and preparation for winter

The Bottom Line

For most homeowners in Waukee, West Des Moines, Clive, Urbandale, and the Des Moines metro, twice-yearly professional window cleaning is the ideal schedule. It keeps your home looking great, extends the life of your windows, and ensures you enjoy maximum natural light year-round.
