TEREG Building Services

What TEREG Building Services does

TEREG Gebäudedienste GmbH is a Hamburg-based full-service building services provider founded in 1963 and owned by the Free and Hanseatic City of Hamburg. The company operates three integrated divisions: Gebäudereinigung (building cleaning) covering maintenance, deep, glass, facade, construction, hygiene, and graffiti cleaning; Gebäudesanierung (building renovation) covering construction, facade, damage, hazardous material (asbestos, PAK, KMF, PCB), and mold remediation; and Technische Dienstleistungen (technical services) covering transport infrastructure and vehicle cleaning, elevator service, pest control, outdoor facilities, and caretaker services. Specialized technologies include the Watercircle TS21 closed-loop water filtration system (up to 2,000 liters/hour, 95% reuse) supplied by A3 Innoteg, Puraqleen chemically-free cleaning, the Four-Color hygiene system, and wet sandblasting (torbo-Prinzip).

The business operates a B2B and B2G (public sector) service delivery model with long-term contracts, primarily serving public transport operator HOCHBAHN (24/7 bus depot and vehicle cleaning), the City of Hamburg (facade and emergency graffiti response), VHH Mobility, and enterprise clients such as Eurofins FM Germany. Services are delivered directly to customer sites in the Hamburg metropolitan area by TEREG's own trained workforce of approximately 850-1,000 employees, making it one of the largest employers in Hamburg's building services sector. The company does not publicly disclose pricing for core cleaning services; disclosed pricing includes paid apprenticeship compensation tiers (€1,125-€1,465/month in 2025-2026) and the Heizungscheck 2.0 energy consultation at €250 net per engagement.

TEREG is publicly owned by the city-state of Hamburg and functions as a municipal enterprise, generating revenue through professional-services contracts across cleaning, remediation, and technical services. Distribution is direct and domestic (Hamburg only), with marketing centered on a company magazine, a careers portal, and industry PR. The company holds NAV membership for hazardous remediation, a 20-year UmweltPartnerschaft Hamburg environmental certification, and a certified electronic whistleblower system, and has won state-champion apprentice awards.
