„Versatility, flexibility and customer focus are key aspects of our service philosophy.”

Our clients are at the centre point of everything we do.

gammaRenax is a highly capable provider of first-rate, integrated integral facility services with 1,800 employees working from 17 locations in all parts of Switzerland. With an annual turnover of more than 62.5 million Swiss francs, the owner-run company is one of the most significant facility services providers in Switzerland, managing a portfolio of over 1,600 properties.

The trend towards bundling of facility services and integrating management contracts is continuing. In close cooperation with our clients, we flexibly respond to evolving individual requirements, optimize our overall services offer, and pass on the resulting cost savings. In doing so, our innovation & service culture as well as our process orientation are of great benefit – also to our clients.

Our certified management system, which records the main processes, has proven highly effective in our daily work. Facility-Gate, developed by gammaRenax, our interactive online tool for services management, has now been expanded with CAD functionality. This allows us to display in the virtual realm the performance targets agreed with the client and to reliably meet them at a consistently high level.

Working with enthusiasm 365 days a year, we are committed to exceeding the expectations of our clients. We attach great importance to transparent communication and respectful interaction with everyone we deal with. 

gammaRenax continuously enhances its Facility Services to the benefit of its customers.
