What Fischbach Group does

Fischbach Group is a privately held German construction services group headquartered in Gelsenkirchen that specializes in the modernization, renovation, and revitalization of existing residential buildings (Bestandsbau). Founded in 1914 as a painting and plastering business, the group has evolved over 110 years into a multi-trade construction platform serving the German housing industry (Wohnungswirtschaft), institutional real-estate investors, and education-sector clients through a network of more than ten wholly-owned subsidiary companies covering scaffolding, facade work, roofing, windows and doors, technical building equipment (TGA), electrical installation, asbestos remediation, and vacant apartment renovation.

The group delivers projects as both general contractor (Generalunternehmer) and general subcontractor (Generalübernehmer), offering end-to-end single-source renovation packages as well as individual trade services. Annual operating capacity exceeds 2,000 vacant apartment renovations, 15,000 window installations, 200,000 m² of insulated facades, 520,000 m² of scaffolding, and over 60,000 m² of renovated roof area. Its proprietary technology stack is a Digitales Controlling-System that monitors construction workflows and supports cost and quality control across projects, rather than a software product sold externally. Recent strategic moves include the acquisitions of ETK Elektroanlagen (2022) and Strack GmbH (2023), an expansion to Berlin, and the appointment of Stefan Lohwasser as Managing Director in July 2024 to restructure the sales organization.

Fischbach generates revenue through project-based, quote-priced construction contracts with enterprise and institutional buyers, reported at approximately €200 million annually on a base of ~500 internal employees (over 1,000 including external staff). The company is family-controlled through Fischbach Holding GmbH, with Danny Fischbach (great-grandson of founder Klaus Fischbach) and Lukas Heise serving as managing shareholders. The PQ-VOB prequalification certificate issued by DQB in December 2023 enables participation in institutional and public-sector tenders, which is increasingly relevant given Germany's decarbonization and energy-efficiency mandates driving large-scale renovation demand.
