Do you have questions about the maintenance of your property? Do you need advice on maintaining the value of your building? Or would you like to place the care of your premises in professional hands? Our Facility Services consultants will be happy to assist you without obligation and show you potential for improvement and tailor-made options.

gammaRenax is more than just a cleaning company. Thanks to the comprehensive range of services, you receive all facility services from a single source and thus have only one contact partner who coordinates and executes all orders for you. gammaRenax is about more - we regularly advise our clients with the aim of maximising value retention and optimising costs. Let us convince you. We would be happy to visit you for a no-obligation technical discussion. You make the coffee, we bring the croissants.

Proximity to our customers and regular personal contact are important to us. That is why we are there for you at 16 locations throughout Switzerland. You can contact us directly locally or via our headquarters - we will be happy to direct you to the right specialists.

We look forward to hearing from you!
