We introduce ourselves.
We plan, implement and maintain all building services installations. This includes in particular:

• Sanitary facilities
• Heating systems
• Comfort ventilation
• Solar systems

Thanks to a modern CAD workstation and a wealth of experience, we are able to plan the systems according to our customers' wishes.

Ten well-trained installers and three motivated apprentices who enjoy their daily work put their heart and soul into realizing everything from small bathroom renovations to large industrial halls.

A well-coordinated team of two service technicians maintains all systems with extensive specialist knowledge.

With us, you get everything from a single source.
We advise. We plan. We implement.

We count on almost 40 years of experience.

The company was founded in 1973 by Josef Schönenberger. Over the next few years, Josef Schönenberger steadily expanded the company.

In 2001, Schönenberger & Partner AG was founded. From this time onwards, Josef Schönenberger and Alex Niedermann were equal partners and the future of the company was secured.

Alex Niedermann completed his apprenticeship as a plumber at Josef Schönenberger in 1988. After additional training as a sanitary draughtsman at an engineering firm and a few years of traveling, Alex Niedermann returned. After successfully completing the master craftsman's examination to become a qualified building services fitter, Alex Niedermann joined the newly founded AG.

In 2008, Alex Niedermann took over the entire company. Since then, Alex Niedermann has managed Schönenberger & Partner AG together with his wife Saskia Niedermann.
