How Often Should You Have Your Windows Cleaned?

Windows do more than just let in natural light—they frame your view, improve curb appeal, and even affect how much sunlight warms your home or business. But over time, dirt, dust, water spots, and pollutants can build up on glass, leaving windows dull and streaky. That brings up an important question: how often should you have your windows cleaned?

The answer depends on several factors, including the type of property, location, and even personal preference.

Residential Homes

For most homeowners, twice a year is a good standard for window cleaning—usually in the spring and fall. This routine removes pollen, dust, and debris that accumulate seasonally, ensuring your windows stay clear year-round.

However, you may want to clean more often if:

• You live near a busy road or construction area (dust and grime build up quickly).

• You’re in a coastal area (salt spray can damage glass if left too long).

• You like your windows looking spotless at all times.

Commercial Buildings

Businesses often need their windows cleaned more frequently than residential homes, since appearance plays a big role in attracting customers.

• Retail stores and restaurants: At least once every 2–4 weeks. Customers notice smudges, fingerprints, and dirt quickly.

• Office buildings: Generally every 2–3 months, though high-rise buildings often follow a set schedule depending on weather and accessibility.

• Healthcare and hospitality industries: Cleanliness is part of the overall experience, so monthly or even bi-weekly cleaning may be ideal.

Environmental Factors

Certain locations require more frequent cleanings:

• Urban areas: Pollution, smog, and traffic increase buildup.

• Forested areas: Sap, pollen, and bird droppings are common.

• Rainy climates: While rain doesn’t always “dirty” windows, minerals and pollutants in the water can leave streaks.

Signs It’s Time to Clean

Even if you don’t follow a set schedule, keep an eye out for these signs:

• Streaks or water spots that don’t go away.

• Reduced natural light indoors.

• Fingerprints and smudges around frequently used windows.

• A hazy or foggy appearance.

In short, residential windows should be cleaned about twice a year, while commercial windows may need cleaning monthly or even weekly, depending on the type of business. The best schedule for you depends on where you live, how your windows are used, and the impression you want to make.

Investing in regular window cleaning not only improves the look of your home or business but also extends the life of your windows by preventing etching and damage from dirt and debris.
