Willi Studer AG

What Willi Studer AG does

Willi Studer AG is a family-owned plumbing and heating contractor headquartered in Kreuzlingen, Switzerland, operating continuously since its founding on March 1, 1960 by Willi Studer and David Egloff. The company provides end-to-end building services including planning, installation, renovation, repair, service, and maintenance of sanitary and heating systems for residential and commercial properties throughout the Canton of Thurgau. Its core service lines are Sanitär (plumbing/sanitary systems) and Heizung (heating systems), with supplementary offerings in energy consulting, Minergie (Swiss low-energy building standard) compliance advisory, and wellness bathroom solutions including whirlpools, saunas, and infrared cabins.

The company's revenue model combines one-time project-based installation revenue with recurring service and maintenance contracts, supplemented by a 24/7 emergency on-call service (Pikett) priced at a flat CHF 150 rate. Distribution is direct-to-customer via field installation and service teams, supported by a physical exhibition showroom in Tägerwilen displaying products from brand partners including Geberit (AquaClean shower-WCs, washbasin products) and Talsee (bathroom furniture). Customer segments span residential homeowners, regional property developers, and institutional clients, with notable project references including Clinic Seeschau Kreuzlingen, Pädagogische Hochschule Thurgau, and multi-family housing developments (Vinea, Seegang, Rosengarten).

Following the leadership transition from founder Willi Studer to his son Hansjörg Studer in 1995, the company executed a planned succession effective January 1, 2020 by bringing former apprentices Daniel Nisple and Marco Binswanger into co-ownership and board roles, while retaining Hansjörg Studer as board president. The workforce ranges from approximately 12-15 visible staff currently to a historical peak of 30+ employees in 2010, supported by a Toplehrbetrieb-certified apprenticeship program. The company uses CAD planning applications for building technology design and emphasizes ecological approaches including renewable heating systems. Ownership remains entirely internal and family-controlled, with no external investors, parent companies, or public listing.
