Memberships and certificates

We are committed: Our own demands were defined as standards. These are understandable, perceptible and quantifiable. Accordingly, Piepenbrock has nationwide DIN EN ISO 9001 certification. Piepenbrock also has ISO 14001 and SCC certification for specific requirements relating to orders.

In the interest of our clients, we are also continuing to further develop our quality. We do this by utilising our memberships in productive networks such as the Bundesinnungsverband des Gebäudereiniger-Handwerks e.V. (BIV) and the German Facility Management Association (GEFMA e.V.).


We have listed the most important associations of which we are a member for our four divisions.
