How to Clean Windows Outside: Expert Tips for Property Managers

Is your commercial property's appearance failing to make the right first impression?  Want to know how to clean windows outside you can't reach? At Astound Cleaning Group, we understand that maintaining pristine windows is crucial for your business image, yet it can be a significant challenge. With over a decade of experience serving businesses across South East England, we've developed solutions to every window cleaning challenge you might face.


Commercial Window Cleaning: Your Complete Guide to Pristine Business Premises


Managing commercial premises comes with unique challenges, particularly when it comes to exterior window maintenance. The British weather, environmental factors, and access issues can make what seems like a simple task become remarkably complex.


Our experience serving diverse commercial clients, from modern office blocks in Croydon to historic buildings in Brighton, has taught us that timing is crucial. The best results come from cleaning on overcast days when the cleaning solution won't dry too quickly on the glass. This is particularly important in coastal areas like Worthing, where salt deposits can be a persistent problem.


Environmental challenges vary significantly across our service areas. In busy commercial districts like Gatwick and Crawley, industrial pollution requires specific cleaning approaches. Meanwhile, our clients in Horsham and East Grinstead often face issues with tree sap and organic debris.We choose each tool with your needs in mind—whether you’re worried about hard water stains, coastal salt, or just want to let more light into your home.


Weather Considerations


  • Choose overcast days to prevent premature solution drying
  • Avoid windy conditions that can compromise safety
  • Schedule regular cleans to prevent build-up of dirt and grime


Common Challenges We Solve


  • Hard water stains
  • Bird droppings and environmental debris
  • Industrial pollution
  • Salt deposits (especially relevant in coastal areas like Brighton and Worthing)

What Do Professional Window Cleaners Use to Clean Windows?


The difference between amateur and professional window cleaning lies not just in technique, but in the sophisticated equipment we employ. Our commercial window cleaning service utilises pure water cleaning systems that eliminate the risk of mineral deposits and streaking. This technology is particularly valuable in areas with hard water, ensuring consistently spotless results that last longer.


We've invested heavily in commercial-grade equipment that goes far beyond what's available to general maintenance staff. Our professional squeegees and specialist cleaning solutions are specifically chosen for commercial applications, considering factors like glass type, environmental conditions, and local water quality. This attention to detail explains why businesses across Littlehampton and surrounding areas trust us with their premises.
