To ensure that you only have "nice" visitors

We have a many years experience retrofitting a Hagen housing association and have gained expertise in providing and installing appropriate security mechanism to the various types of windows, doors and fittings.

Several of our colleagues have completed training in the Siegenia-Aubi training for retrofitting windows with inward fittings according to DIN (industry standard) 18104. This training is accredited by the North-Rhine Westphalia Crime Department.

You can ask us for more information or contact the NRW Crime Department.
