Bildau and Bussmann - High Performance Windows and Doors

Raglan, New Zealand
7 Maungatawhiri Road Raglan Waikato 3295 NZ

Bildau & Bussmann began as a traditional carpentry business and has remained true to the roots of the craft and to the material wood. As an owner-managed, traditional family business, sustainability is a high priority for us. This applies not only to the selection of our materials, but also to our company culture:

In our opinion, efficient and good work takes place in a framework in which everyone feels comfortable and taken care of – this applies to both our customers and our employees. Particularly in complex projects, it is important to work in close cooperation with each other in order to achieve optimal results.

When doing international business, there are additional challenges due to language and cultural barriers. We therefore attach great importance to providing our customers with employees from their own country. Projects are always understood and developed in the context of their environment in order to achieve the best result.

We don’t see ourselves as just a window manufacturer: our great strength lies – in addition to production – in advice and planning, as well as after-sales service. We see ourselves more as a companion to our customers in all questions relating to wooden windows and doors in their respective project, rather than as a pure supplier. Our focus is on establishing and maintaining long-term customer relationships.

In addition to a high level of personnel commitment, we invest heavily in software development in order to offer our customers all the advantages of digitalization for efficient and error-free communication, from project planning to after-sales service.
