Building Service Dietrich West

What Building Service Dietrich West does

Building Service Dietrich West (legal entity Gebäudeservice Dietrich West KG) is a third-generation, family-owned German building cleaning and facility services company headquartered in Wuppertal. Founded in 1918 by Otto Dietrich and today led by Thomas Dietrich as sole owner and Managing Director, the company delivers recurring Gebäudereinigung services (maintenance, glass and facade, specialized/construction, and industrial cleaning) alongside Gebäudedienste including caretaker, security, kitchen, conference, green area maintenance, and winter services. The workforce of 4,000–4,500 employees is deployed through three legally independent operating entities covering West, North (Hamburg), and East (Senftenberg) Germany, with additional offices in Berlin, Dresden, and Leipzig.

The company serves at least eight industry verticals, with healthcare (hospitals and care homes, including OP and ICU cleaning), industrial and commercial customers, banks and insurance, real estate, retail/wholesale/DIY, public institutions, hotels, and events each described as core. Technical and quality differentiation rests on a 30-year stack of ISO certifications (ISO 9001 since 1995, ISO 14001, BS-OHSAS 18001, ISO 50001, ISO 45001), and on a digitalization initiative anchored by the proprietary GSD App developed with s2k digital (founded by Thomas Dietrich's daughter Katharina). Operational infrastructure includes a 280,000 kWh/year photovoltaic installation and 25-point EV charging network at the Wuppertal headquarters.

Revenue is generated through subscription-style maintenance contracts, with pricing customized per object after on-site inspection; one-time services such as clearance are also offered. Go-to-market is direct B2B field sales (Regionalleiter and Vertrieb roles) targeting enterprise and mid-market clients, supported by an active industry-association presence (Thomas Dietrich chairs WFBSC and serves as Bundesinnungsmeister). Recent strategic activity centers on the January 2024 acquisition of IMPULS Gebäudedienste GmbH in Cologne and the entry of the fourth generation into the corporate group.
