Stalder STM Montagen GmbH

What Stalder STM Montagen GmbH does

Stalder STM Montagen GmbH is a Swiss construction-assembly subcontractor founded in 2006 and headquartered in Entlebuch, Canton of Lucerne. The company specializes in the installation of building envelope components — facades (ventilated, post-and-beam, wood/metal/glass), metal construction elements (windows, doors, glazing, railings, light steel), and, since 2021, wood construction assemblies. It serves general contractors, developers, and institutional clients across Switzerland through direct subcontracting and competitive bidding, delivering large-scale projects such as Europaallee Zürich (CHF 4.37M assembly volume), Polizei Zentrum Bern (20,000m²), and Hagnau Ost (32,220m²).

The business operates on a project-based, quote-driven professional services model with no publicly disclosed pricing. It has no proprietary software or product IP; its competitive position rests on a tiered workforce of approximately 80 qualified Monteurs supervised by 3 Montageleiter, 8 Chefmonteure, and 18 Gruppenführer. Marketing is limited to a project-references website, and distribution is purely direct (B2B subcontracting on-site at construction projects). The company is privately held by the Stalder family, with Martin Stalder as Managing Director/Owner and Urs Stalder as Co-Owner.

A wholly-owned adjacent subsidiary, Stalder STA Abdichtungen GmbH (founded 2011), operates in waterproofing/sealing, complementing the parent's facade offering. The company relocated to larger premises at Dorf 34, Entlebuch in 2022, and continues to operate as a Switzerland-only, non-tech-enabled specialty subcontractor with no external institutional investors.
