We have been regularly installing intercom systems in existing detached houses and apartment buildings in German-speaking Switzerland since 1990. In connection with the intercom systems, we carry out all the necessary work, such as converting the front doors for electric opening, adapting the outside intercom to the new conditions, adapting or reinstalling letterbox systems. Thanks to our experience, we can provide you with guide prices for the complete installation of a system on this website. After inspecting the property, you will receive a detailed quote with a guaranteed all-inclusive price! And this price is always the same, regardless of whether your property is in Berne, Zurich or Basel.
