Technical know-how

We have a national network of tradespeople, specialists and experts at our disposal. Nobody offers a service quite like us: we are very familiar with the price-performance ratio in Hamburg and the surrounding area.

GGM Hamburg Service

We are always and reliably there for you. We take care of your property responsibly and with transparent digital documentation. Individual, property-specific consultation allows us to recognise trends and integrate these into working processes in an ideal manner.


Ms Agnes Hellmann founded the company in 2002 based on her love of Hamburg. As a result of high customer satisfaction and recommendations, the company developed very quickly from supervising individual properties into a service provider which is in great demand in Hamburg.

The personal note which has characterised the company ever since the beginning is one of our key values. In the beginning, the founder used to carry out flat inspections and hand-overs herself.

The technical division was further expanded as of 2011
and, since 2014, has been professionally organised along with Mr Ralf Thomas Esch as Managing Partner for the Management and Coordination of the Technical Division. To this day, this “hands-on” mentality can be seen in every member of the large GGM family.  

Our goals for the future are clearly defined: we wish to build upon our status as an essential component of facility management in Hamburg and the surrounding area. We would like to exceed the high demands of our customers again and again, as well as offer a forward-looking added value.
