Facade Cleaning · 25 August 2026
What Is the Right Season and Weather for Facade Cleaning?
Wind, temperature and rainfall directly affect both the safety and the result of aerial facade cleaning. Getting the timing right means the job gets done properly in one pass.
Because facade cleaning is an outdoor operation carried out by drone, weather conditions sit at the centre of planning. Not every day of the year is suitable — but catching the right window matters for both safety and a clean result.
How does wind affect the operation?
Above a certain wind speed, safe flight and accurately directing water at the target both become harder; in those conditions the operation is postponed to a more suitable day. Wind is assessed on site before every flight.
Is cleaning done on rainy or very hot days?
Applying water during rainfall serves little purpose, and drying time may be needed right after. On very hot days water evaporates quickly, which can raise the risk of mineral marks; the cooler hours of the day are preferred in that case.
Can facade cleaning be done in winter?
Yes, on days and hours with no freezing risk; work is postponed when there is a freezing risk. The suitable window in winter can be narrower than in summer.
When is the operation date finalised?
After the site survey assesses the building and its surroundings, a date is proposed based on the suitable weather window; if the forecast changes, the date can be rescheduled together with building management.
