Ich kannte schon seinen Vater absolut seriös und kompetent. Da passt der Spruch: Qualität hat einem Namen

Ich besitze mehrere Liegenschaften und habe bereits verschiedene Malerbetriebe im Säuliamt und Freiamt ausprobiert. Herr Prater hat mich mit seiner sehr kompetenten Beratung und seinem persönlichen Engagement überzeugt, und auch die Ausführung durch seine freundlichen Mitarbeiter war erstklassig. In Zukunft werde ich nur noch mit der Firma Maler Prater AG zusammenarbeiten. Sehr empfehlenswert!
