On January 1, 1985 we founded the company DUO TOP SERVICE Ltd. The TOP SERVICE stands for our top service. The somewhat unusual name comes from the fact that we did not only offer ourselves as plumbers, but also wanted to carry out various other works. For example, our advertisement said: 'Execution of plumbing, roofing, gardening, painting, demolition and cleaning work, as well as other services'. Which was quite well received in the early years. But soon the workload as plumbers had grown to such an extent that we had to devote 100% of our time to this task. In the following time we were able to realize large and interesting projects. Also special orders like ridge turrets, weather vanes, gargoyles and ornaments are among our references. In 2016 our team doubled in size and we welcomed our two sons Mike Bussinger and Patrick Feusi, who successfully completed the foreman school in November. Shortly afterwards, Patrick Feusi decided to continue his professional further education, Patrick Feusi decided to add the master school to his professional training. He was then able to successfully implement this in conjunction with a large plumbing company. To fill the gap at Duo Top-Service GmbH, we were able to recruit Pascal Bussinger to our team. He also successfully completed the foreman school at his previous employer. Now the world's largest "Duo" is looking forward to future tasks and challenges.

Super ausgeführte, professionnell ausgeführ-te Arbeiten. Diese Firma kann jederzeit wieder empfohlen werden.

Die Gasleitung wurde bei uns in der Strasse abgestellt. Nun haben wir eine sparsame Wärmepumpe. Schlussendlich war das die richtige Entscheidung und wir wurden super beraten und betreut.

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
