Window cleaning for businesses

Window cleaning plays an important role in the perception of your premises. Whether it's a supermarket, a convenience store, a school, a head office, a hospital or an industrial site, clean windows inspire confidence.
Window cleaning is important because it reassures your visitors, partners, customers and employees alike. This is confirmed by the Ipsos x Onet study carried out in July 2021, which highlighted that 9 out of 10 French people consider hygiene and cleanliness to be a fundamental notion.

When and how often should you wash your windows?

There's no set frequency, as this will depend on the use of your premises and their geographical location. In fact, certain premises, such as those open to the public, retail outlets, medical establishments and museums, must be irreproachable with regard to their visitors. A frequency of once a month is therefore a minimum for this type of building.

For head offices, our teams recommend a visit once a quarter. Clean windows contribute to the well-being of your employees, as they let in more light.

The frequency with which you clean your windows will also depend on the location of your business. The proximity of construction sites, high-traffic areas such as freeways, or inclement weather, will accentuate the need for window cleaning.

Last but not least, there are certain times of the year when it's best to wash windows.

It's advisable not to wash your company's windows during hot spells. This is because the heat causes the products used on the windows to dry quickly, leaving marks on the glass. As with hot weather, rainy days are also not ideal for window cleaning. This is because traces of raindrops will remain after the window cleaner has passed through. Window cleaning can also be carried out as part of end-of-job cleaning services.

What are the different types of window cleaning?

There are 3 different types of glazing work:

• Windows accessible from ground level at a maximum height of 2.50 m. This represents 95% of interior glazing.
• Glazing at height: Depending on the height to be treated, our Onet Cleaning and Associated Services teams will suggest the use of scaffolding or a cherry picker. In our window-cleaning business, we always prefer a cherry picker to scaffolding. Scaffolding is mainly used when it's not accessible by aerial platform.
• Climbing or abseiling: This specific method is used on highly complex buildings, such as the office blocks at La Défense. High-altitude window cleaners, also known as rope access technicians, are equipped with appropriate protective and safety gear (harness, helmet, gloves, overalls and mask).

What materials and products are used for window cleaning?

Our Onet Propreté & Services cleaners specialize in glazing, using products and materials adapted to glass surfaces. The cleaning products they use make dirt soluble, so it's easier to remove. They also dust, wash, degrease and shine without leaving a trace.

The products we use are also specially designed to dry quickly, leaving no streaks or drips.

Last but not least, our agents are trained in the use of cleaning materials dedicated to glazing. They can use the H2O system, for example. This system consists of a long pole through which water is passed. It's ideal for reaching great heights without using lifting equipment.

Who can clean windows?

At Onet, a window cleaning company, our cleaners are specifically trained in glazing services. Cleaners pass a professional qualification certificate issued by INHNI (the cleaning industry's training body). This certificate is a way of showcasing the professionalism of our operatives through the award of a certifying diploma.

Window cleaning at great heights or with difficult access is a specific profession, and again requires special training. Only window cleaners with the "Certificat de Qualification Professionnel Laveur de vitres spécialisé travaux en hauteur" can work on your premises.
