Gallo AG was founded as Gallo Reinigungen AG in Zurich in 1973. With façade cleaning and sandblasting work, we have literally worked our way up buildings. Gallo Reinigungen Cham AG was founded in 1983. In 1985, Eduard Karisch Senior took over the group of companies on his own. We gradually expanded into the cantons of Aargau, St. Gallen, Ticino and western Switzerland and continuously expanded our range of services. Since 2004, the Gallo family business has been managed by the second generation of the family, brothers Eduard and Marco Karisch - with comprehensive services for the whole of Switzerland.
