Nachdem ich in unserer Firma einige tolle Türen in der Produktion gesehen habe, wurde auch bei uns privat der Haustürenersatz ein Thema. Mit unserer neuen Kunststofftüre von Adeco waren wir von Anfang an sehr zufrieden. Wir konnten mit dem Online-Konfigurator einige Varianten ausprobieren und die Türe mit Tipps vom Fachmann ganz nach unseren Vorstellungen gestalten. Sowohl die Demontage der bestehenden Türe, als auch die Montage wurde sehr speditiv und sauber ausgeführt. Herzlichen Dank dafür!
