Windows are cleaned every two months, in the odd months, by the 'Reinland' company. They clean all the windows in the façades on (Kleine) Nobelstraat, Prinsestraat, and Kerkplein. The windows in the corner flats facing Torenstraat are also cleaned, insofar as they can't be reached from the inside.

The windows of most of the flats on Torenstraat are not done by Reinland, since the window cleaners can't use their hydraulic platform in the middle of the overhead power lines for the trams.

The bedroom windows on the second access gallery along (Kleine) Nobelstraat are cleaned from within the inner garden. Also from within our garden are the windows of the flats on Prinsestraat and Kerkplein cleaned up to the fourth floor. As are the windows in the stairwells and in our panorama lifts.
