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.

Vor einigen Wochen habe ich mich für den Service eines Solartechnik-Anbieters entschieden und bin unglaublich zufrieden. Die Fachkompetenz des Beraters war beeindruckend und er hat mir alle Schritte geduldig erklärt. Dank der Unterstützung hat alles schnell und unkompliziert geklappt. Es ist toll zu wissen, dass ich nun umweltfreundliche Energie nutze!

Heizung ausgestiegen am Freitag 22.12.23 um 14.20h (Region Zürichsee). Servicetechniker vor Ort um 15h. Fehler rasch eruiert. Ersatzteil nicht an Bord des Servicefahrzeugs, da ältere Anlage. Innerhalb von 2 Stunden von Technikerkollegen (Region Chur) organisiert und eingebaut. Bravo. Grosses Dankeschön für diesen super Service vor den Festtagen!
