I pressure-wash facades with a flat-jet nozzle at a maximum pressure of 120 bar to avoid plaster damage.
Also uses dedicated liquids for facades (e.g. Tenzi Apc Out) to improve efficiency.
That is the most effective way to remove dirt, algae, and moss from the facade, restoring the building's aesthetics.
If you wish to DIY, be careful around windows, lamps, and electrical sockets, and perform this procedure in the summer to speed up plaster drying.
Prices in 2026:Standard cleaning costs start at 4 euros per m² and depend on the level of dirt.
