Von der Planung bis zur Ausführung wurden wir fachlich sehr gut beraten. Die Arbeiten wurden präzise, sauber, exakt oder besser gesagt einfach perfekt ausgeführt. Der Zeitplan wurde immer eingehalten. Mit dem fertigen Ergebnis sind wir sehr zufrieden. Die Remo Schönenberger AG mit ihrem zuverlässigen Team kann ich nur weiterempfehlen. Vielen Dank für die schöne Zusammenarbeit und weiterhin viel Freude an eurer Arbeit. Renata Sieber
