Can washing windows become a secret weapon?

Daily exposure to dirt, pollen and urban dust will gradually make your office windows dull – so imperceptibly that you may not notice until someone from the outside draws your attention to it.

Customer story: Artur, the head of an IT consultancy firm in Ülemiste City, was about to hold an important client meeting in his 500m² office when a comment from a co-worker drew his attention to the windows.

“The natural light was too dim,” recalls Artur. “When I looked closer, I saw that our gorgeous glass walls were covered with a thin layer of grey. I had been concentrating on so many other things that I hadn’t noticed the need for regular window washing. The dirt was particularly visible in direct sunlight. A quick solution was not possible and the meeting took place in a dark room. Afterwards, the client admitted that the room felt somehow “lifelike” compared to other companies they met.”

The impact of window cleaning on light and worker productivity

Research has consistently shown that natural light has a direct impact on worker productivity and well-being. Researchers at Northwestern University found that workers who work in rooms with adequate natural light are on average 18% more productive and experience 63% fewer headaches.

Without regular window washing, dirty glass surfaces can significantly reduce the transmission of natural light:

Light dust film: 15-20% less light
Urban background (air pollution): 25-30% less light
Seasonal pollution (pollen, rain marks): up to 40% less light.

In Estonia, maximising light is particularly important in the wide field:

Only 6-7 hours of daylight in the winter months
Low sun creates more reflections, making dirty windows even more noticeable.
Long hours of darkness increase the need to maximise light penetration during the working day

The success story of window cleaning: How regular maintenance transformed Arthur's business

After an unpleasant experience with an important client, Artur decided to rethink his office window maintenance strategy.

Solution and implementation:

Artur mapped all the glass surfaces in the office (over 1220m²) and their specificities.
A regular maintenance plan was drawn up for four main cleanings per year, plus rapid response to emergency needs.
Cleaning work was scheduled for early morning (6:00-8:00) so as not to disturb the office.

Measurable results:

Measurement of natural light showed a 35% improvement after the first thorough clean-up
Employee satisfaction survey shows 27% increase in work environment ratings
Energy consumption for lighting reduced by 15%, reducing the company’s ecological footprint.

Arthur’s conclusion: “Window cleaning seemed like a trivial issue at first, but it has proven to be one of the easiest ways to improve the working environment. Clean windows aren’t just an aesthetic issue – it’s an investment that benefits both the wellbeing of employees and the impression our customers have of our company. It’s now as much a part of managing our office as maintaining our IT systems. “

Frequently Asked Questions (FAQ)

How often should windows in commercial properties in Tallinn be professionally cleaned?

The optimal frequency of washing depends on several factors. In city centres and high-traffic areas, we recommend washing windows at least quarterly. In the commercial area of Ülemiste City, it may be necessary to wash windows every 3-4 months. In the spring season (April-May), an additional washing cycle is recommended to remove pollen, and in the autumn (October-November), a thorough washing of windows is also recommended before the winter season. For IT companies, where the quality of the working environment is particularly important, we recommend a personalised washing schedule that takes into account the location and specific needs of the building.

How can window cleaning take place in an IT company without interrupting work?

Professional window cleaning service providers adapt to your company’s work schedule. We offer services outside normal working hours – early mornings (6-8am), evenings (after 6pm) or weekends. For larger offices, we can work in zones to minimise disruption. All tools and methods are chosen to cause minimum noise and disruption. We recommend scheduling window cleaning in advance of regular events or meetings.

What are the specific challenges in cleaning windows in high-rise buildings (such as Ülemiste City)?

Window cleaning in high-rise buildings requires specialised equipment and training. The main challenges are: ensuring safety when working at heights, the impact of wind on access to windows, the need for special lifting or climbing equipment, and taking into account the specificities of buildings. We use equipment that complies with European safety standards, and all our technicians are trained in safety at height. In the case of the Ülemiste City buildings, we have the experience and the necessary permits to clean the windows of all the buildings there.

Are window cleaners safe for sensitive IT equipment?

Yes, we use cleaning products specially developed for commercial environments and electronic sensitive rooms. They do not contain aggressive chemicals that could damage electronics if vaporised. In addition, we use microfibre cloths and special cleaning systems that minimise the amount of liquid and its spread. When carrying out the work, we take precautions when working near sensitive equipment. If required, we can provide additional protective grating to temporarily protect critical equipment during the work.

How do winter temperatures affect window cleaning in Tallinn?

In the Estonian climate, it is important to take temperature fluctuations into account. We use special frost-resistant cleaning products that work effectively down to -10°C. In winter, it is especially important to remove salt residues and dirt from windows, which can damage the glass. We schedule winter window cleaning during the day when temperatures are higher. If weather conditions are particularly harsh, we offer flexible schedule adjustments to ensure optimal results.

What are the differences between home and professional window cleaning?

Professional window cleaning differs from domestic cleaning in several important ways:

Specialised tools: we use professional door cleaners, microfibre cloths and special glass cleaners.
Technique: T-shaped cleaners, telescopic applications for high windows, streak-free cleaning processes.
Safety: equipment and training for working at height
Cleaning products: pH-neutral, environmentally friendly solutions that also effectively remove grease and mineral deposits.
Result: a complete streak-free and residue-free clean that lasts longer.

Can window cleaning help reduce energy consumption in the office?

Yes, clean windows have a direct impact on energy consumption. Dirty windows block natural sunlight, which means more electric lighting is used. In winter, clean windows can let in more of the sun’s warming rays, reducing heating costs. Studies show that in offices with optimised natural light, energy consumption for lighting can be reduced by up to 25%. This translates into both financial savings and a smaller ecological footprint.
