Here are a few points to keep in mind as a customer: It is mandatory to close all windows during façade cleaning, including basement windows. We recommend removing roller shutters. Stay with the blinds up. It is also important that the balcony be fully emptied before it is cleaned. There must be no obstructions in any window frames or sills. Sensors for temperature, flower pots, etc. The façade washing requires about three metres of space around it. It is therefore advisable to move away flower pots, benches, garden accessories, etc. Parking lots adjacent to work areas should be kept free as much as possible so that we can work unhindered everywhere with our work equipment.
