Professional window cleaning and glass cleaning in Leuven
Want clean windows without doing the work yourself? De Kozijns provides professional window cleaning for homes and businesses in Leuven, Herent and throughout Flemish Brabant — inside, outside or both, as a one-off or regular service.
Professional cleaning for windows and glass
The Dutch terms ramenwasser, glazenwasser and ruitenwasser all refer to the same service: expert cleaning of windows, glass and frames. Whatever term you use, the result is clear glass and a well-kept exterior.
We work in Leuven, Kessel-Lo, Heverlee, Herent, Oud-Heverlee, Bertem, Holsbeek, Rotselaar, Kortenberg, Tervuren, Overijse and the wider Flemish Brabant area.

Window cleaning with purified water
Purified water is free of limescale. Using telescopic poles, we clean exterior windows safely and efficiently, including upper floors, without resting ladders against your facade.
Whether purified-water cleaning is the best option depends on access and the situation. For interior cleaning and heavily soiled glass, we work by hand using professional equipment.
Does your facade need freshening up too? Explore our facade cleaning, our RENEW colour restoration for exterior joinery or solar panel cleaning.
