Why Commercial Window Cleaning Frequency Matters

There’s something about the arrival of spring that makes us want to freshen everything up—and your commercial windows should be no exception. As the days grow longer and the sun starts streaming through the glass, clean, streak-free windows can completely transform how your business looks and feels.

At Exterius, we offer expert commercial window cleaning services that help your building shine from the outside in. Whether you manage an office, retail unit, or multi-storey commercial property, now is the perfect time to get your windows professionally cleaned.

Commercial Window Cleaning Frequency: The Spring & Summer Advantage

1. Better Weather, Better Results

Warmer temperatures and more stable weather make spring and summer the ideal time for exterior cleaning. Water evaporates more evenly, reducing streaks and improving the finish. Plus, we can clean more safely and efficiently in calm, dry conditions.

2. Brighter Days Demand Brighter Windows

With increased daylight hours, natural light plays a bigger role in how your space feels. Clean windows allow maximum sunlight to flood your interior, creating a more inviting, energised environment for staff and visitors.

3. Increased Footfall = More Visibility

For retail and hospitality businesses, spring and summer bring more customers through the door. Polished glass and well-kept facades make a lasting impression. Our retail window cleaning helps stores, cafes, and shopping centres look their best for every passer-by.

4. A Fresh Start for the New Financial Year

Many businesses schedule building maintenance in Q2. Adding commercial building window cleaning to your spring checklist ensures your premises are ready for inspections, tenant visits, and summer trading.

How Often Should Commercial Windows Be Cleaned?

The ideal frequency depends on your building’s location, usage, and industry standards. Here are some general guidelines:

Monthly:

High street shops or retail parks
Restaurants, cafes, and hotels
Buildings in areas with high pollution or nearby traffic

Every 6-8 Weeks:

Offices in urban areas
Ground-floor windows of healthcare facilities or gyms
Warehouses with client-facing entrances

Quarterly:

Office blocks in quieter areas
Schools and community buildings

Tailored Schedules:

We offer fully bespoke cleaning plans based on your specific site and operational needs. Whether you need weekly office window cleaning services or seasonal cleans for a retail complex, we’ll create a plan that works for you.

Why Invest in Professional Commercial Window Cleaning?

1. Enhance Your Brand Image

Dirty windows can make your entire building look neglected. Clean glass gives a professional, cared-for appearance that reflects positively on your brand.

2. Boost Natural Light and Productivity

Grime and dust block sunlight. Cleaner windows mean brighter interiors, better moods, and reduced reliance on artificial lighting—especially in open-plan offices and communal workspaces.

3. Improve Window Longevity

Environmental build-up can damage seals and etch into glass. Regular commercial window cleaning prevents long-term wear and protects your investment.

4. Ensure Safety and Compliance

Our team is fully trained, IPAF-certified, and equipped to handle everything from ground-floor windows to glass facades up to 75ft. No ladders, no risks.

5. Eco-Friendly Solutions

We use heated, purified water with no harsh chemicals—great for sustainability, great for results.
