The challenge of professional glass cleaning
Iris' window washers have the solution:
Clean windows are your company's calling card, but finding a reliable window cleaner is often a challenge. Dirty windows give an unkempt impression to customers and demotivate employees due to lack of natural light.
Washing windows yourself takes valuable time and poses safety risks. Inexperienced window washers leave streaks or damage window frames. When working at heights without proper certification, you risk fines and liability for accidents.
Iris provides professional window cleaners who are trained to work safely and extremely efficiently. Our window cleaners are VCA certified, fully insured, and equipped with specialized equipment. We guarantee perfect results with streak-free windows, thanks to a regular window cleaner who knows your building and visits according to a precise schedule.
Why choose Iris as your window cleaner?
Using state-of-the-art techniques and environmentally friendly products, we clean windows at any height, even in hard-to-reach places. We work with osmosis installations for streak-free results and can reach heights using aerial work platforms, suspended platforms, and rope access techniques.

Frequently asked questions about window washers
How often should a window cleaner visit?
The ideal frequency for a window cleaner depends on your location and type of business. Offices in city centers often require a window cleaner on a monthly basis, while for businesses in green environments, a window cleaner quarterly may suffice. We would be happy to advise you on the optimal frequency.
Do your window washers also work in the winter?
Yes, our window cleaners work all year round. In freezing weather, we use special techniques and antifreeze. A professional window cleaner can work safely even in low temperatures, although we do not schedule window washing in extreme weather conditions.
What does a professional window cleaner cost?
The price for a window cleaner depends on the number of windows, accessibility and desired frequency. A regular window cleaner by contract is more economical than single assignments. Request a free quote for a customized price.
Are your window cleaners insured?
Absolutely. Every Iris window cleaner is fully insured for liability and accidents. We have specific coverage for working at height. You are not at any risk when our window cleaners are at work.
Can your window washers also do hard-to-reach windows?
