Building cleaners

What Building cleaners does

Building cleaners is the operating brand of the Gebäudereiniger-Innung Berlin, a regional trade guild representing approximately 120 building cleaning companies in Berlin under the national umbrella of the Bundesinnungsverband des Gebäudereiniger-Handwerks (BIV). Founded in 1934 and headquartered at Köpenicker Str. 148, 10997 Berlin, the entity is structured as a Körperschaft des öffentlichen Rechts (corporation under public law) within the German Handwerk system. Its core function is collective representation: it advocates for member firms, administers the regional framework of the Handwerksrolle (crafts registry), and co-negotiates collective bargaining agreements with the IG BAU trade union, including the Mindestlohntarifvertrag whose Allgemeinverbindlichkeit (general applicability) took effect 01.02.2025. There is no venture capital, private equity, or public-company ownership; governance is distributed among member companies through an elected Vorstand led by Obermeister Olaf Bande and managed operationally by Geschäftsführer Dennis Loeper.

The guild's product surface is vocational training and certification, delivered through wholly-owned subsidiaries Bildungszentrum Gebäudedienstleister Berlin (Breitenbachstraße 7-8, Berlin-Reinickendorf) and Fachschule für Gebäudereinigung. The offering includes the Meistervorbereitungskurs in four parts (practical, theory, business administration, AEVO trainer aptitude), a BIV-certified Objektleiter Lehrgang for site managers, a Vorbereitungslehrgang zur Gesellenprüfung, and recurring continuing education seminars on occupational safety, procurement law, and infection control. Pricing follows a member/non-member tier: e.g., Meister Part I+II at €4,000/€5,000; Objektleiter at €1,150/€1,900 plus €175 exam fee. Adjacent services include the Qualitätsverbund quality-mark program, a Fachbetriebe-Suche directory, certified Sachverständige expert witnesses, and tariff information services under the Posted Workers Act (AEntG).

Revenue mechanics rely on member dues from ~120 Berlin members, training-course fees, advisory/expert-witness engagements, and selective endowment income (notably the Carl-Gegenbauer-Preis funded at €4,500/year by the Carl Gegenbauer Foundation). Commercial go-to-market centers on the website (gebaeudereiniger-berlin.de), Facebook / BVG-subway image campaigns such as "Putzi-Image bekämpfen," annual events (Freisprechung, Innungscup, Netzwerkfrühstück, Sommerempfang), and the Bundesleistungswettbewerb (Deutsche Meisterschaft) hosted in Berlin in 2024. The guild also operates the Berliner Schulpate school-sponsorship program and partners with Verbundberatung Duale Berufsausbildung, Ausblicke mentoring, and Jugendberufsagenturen to widen the apprentice funnel. No revenue figures are publicly disclosed.
