What is window cleaning?
Window cleaning is the professional cleaning of windows, glass, and window frames, both inside and out. While regular cleaning stops at the interior, window cleaning focuses on clear glass and an unobstructed view. Clean windows let in more light and give any commercial building a well-maintained appearance.
Rainwater, fine dust, and exhaust fumes quickly form a gray haze on the glass. This layer adheres firmly and is difficult to remove with ordinary window cleaning. Our window cleaners use the right techniques and materials to ensure that the dirt is removed and the glass dries streak-free. Regular window cleaning also prevents damage to windows and frames and extends their lifespan.

How often do you have your windows cleaned?
How often window cleaning is needed depends on the location and use of your building. A window cleaner often comes by once a month. With a maintenance subscription, we typically clean your windows eight times a year. Retail and hospitality businesses usually opt for a higher frequency, because their windows must always be clean. Regular window cleaning not only maintains the building’s appearance but also prevents dirt from accumulating and causing damage to the glass and window frames. We’d be happy to advise you on a cleaning schedule that fits your business operations.

Our Approach: How Our Window Cleaners Work
Every building requires a unique approach. Our window cleaners choose the method that best ensures the best results—safely and efficiently—for each specific situation.
Streak-free with osmosis water
For the best results, we use reverse osmosis water. This is demineralized water from which all minerals, lime, and other impurities have been filtered out. The main advantage: when the water dries, it leaves no streaks or spots on the glass. The windows dry streak-free and therefore stay clean longer. For most buildings, reverse osmosis is the fastest and cleanest way to wash windows.
Telescopic Window Cleaning at Height
Using telescopic window-cleaning equipment, we safely clean high windows from the ground. Our special telescopic brushes work at great heights, often without the need for a ladder. The brush removes stubborn dirt, while the reverse-osmosis water immediately rinses the glass for a streak-free finish. When the height requires it, we use aerial work platforms. This ensures our employees always work safely and that building occupants are not inconvenienced.
Hand Washing as a Custom Service
Not every window can be cleaned with a brush. For specific window designs or hard-to-reach corners, our professionals switch to traditional manual window cleaning. Using a squeegee, a window cleaning cloth, and a small amount of cleaning solution, we expertly clean every window, including the frames and woodwork. This ensures that no window is left out.

Our window cleaners work for a wide range of business clients, from facility managers to property managers. For every type of building, we tailor our approach and schedule to your business operations.

How much does window cleaning cost?
The cost of window cleaning depends on several factors: the size of the building, the frequency of service, whether the work is interior or exterior, and the location of the property. The price is based on labor, materials, and travel expenses. Regular window cleaning is more cost-effective than one-time cleanings, as it prevents dirt from building up.
We do not offer a fixed price per square meter, because no two properties are alike. That is why, after a brief assessment, we prepare a customized quote. At 12B Clean, you know exactly what to expect upfront: the quote is the final bill, with no surprises later on. If you have any doubts about our approach, we’ll first perform a free trial service so you can experience our quality before you give your approval.

Frequently Asked Questions About Window Cleaning
How much does window cleaning cost per square meter?
We do not charge a fixed price per square meter, because no two properties are alike. The costs depend on the size, frequency, accessibility, and whether the work is indoors or outdoors. After a brief assessment, you will receive a customized quote.
What kind of soap do window cleaners use?
Professional window cleaners usually use osmosis water: demineralized water free of minerals and lime, which dries without leaving streaks and therefore does not require soap. When washing by hand, we sometimes add a small splash of dish soap to lukewarm water. A little rinse aid can help achieve an extra-shiny result.
Do you also work outside of office hours?
Yes. Our window cleaners work outside of your business hours or during periods of low traffic as much as possible, so that your employees and visitors are not inconvenienced. We coordinate the schedule with you in advance.
How often should windows be washed?
For most commercial properties, monthly window cleaning is sufficient. With a subscription, we typically clean your windows eight times a year. Retail and hospitality businesses often opt for a higher frequency. The ideal frequency depends on the location and use of your property.
What is the difference between window cleaning and facade cleaning?
Window cleaning focuses on cleaning windows, glass, and window frames to ensure a clear view. Facade cleaning involves the exterior walls and siding of a building, often using different techniques and materials. Both services can be easily combined to achieve a complete, presentable exterior.
