WOHN-UNION Technik GmbH (formerly CERTUS Building Service GmbH) was founded in 2008 from a deep passion for real estate and has since developed into an established medium-sized company in the Berlin and Brandenburg region. What began at the time with only 5 employees and the care of 7 objects is today a success story! Our mission is to not only preserve the value of our objects, but to constantly increase them. Our highly motivated team stands for this – every day. We measure ourselves on this claim, and that is exactly how we want to be perceived. With more than 110 employees, we now provide approx. 13,000 units and over 55,000 m2 of commercial space at over 47 locations. Our service portfolio includes house master services, building cleaning, building technology and services. We understand ourselves not only as a service provider, but as a partner of the real estate owners and managers. Our aim is not only to maintain the living and working value of the properties we serve, but to actively increase.
