Takeover of the glass and frame cleaning in the buildings in the city of Münster, which are organizationally part of the LWL headquarters.

Regular cleaning of around 17,300 m² of door and window glass surfaces, glass canopies, glass roof surfaces, glass walls and glass surfaces of elevators. The use of lifting platforms/aerial work platforms is absolutely necessary in some areas. Other surfaces can also be cleaned using cleaning rods (osmosis method). Due to the current condition of the glass and frame surfaces, it is necessary to carry out a basic cleaning of the specified surfaces once at the beginning of the contract.
