Herr Müller war am 29.11.2021 bei uns. Wir haben Herr Müller schon zum dritten Mal angerufen, nachdem er bei seinem ersten Besuch bei uns schon ausgzeichnete Arbeit geleistet hat! Herr Müller ist ein Profi und macht nicht mehr als nötig. Er hat uns seine Arbeitschritte gut verständlich erklärt, bevor er den Schaden reparierte. Herr Müller ist sehr freundlich, arbeitet sehr sauber und effizient. Wir sind sehr froh, dass wir einen so guten Fachmann kennen! H.U. Kaltbrunner Uster
