Sehr gute und professionelle Arbeit. Freundliche Kommunikation. Sehr empfehlenswert. Kann nur positiv über die Firma sprechen.

Herr Nyffenegger hat uns durch seine ausserordentlich hochwertige Arbeit überzeugt. Wir haben unter anderem ein Insektenschutzgitter für eine grosse Schiebetür installieren lassen - Material, Verarbeitung und Montage absolut top! Ein Spezialist seines Fachs! Sehr zu empfehlen!
