BLESS

What BLESS does

Bless AG is a family-owned Swiss specialist contractor headquartered in Erstfeld, Canton Uri, delivering the complete building envelope (Gebäudehülle) from a single source. Founded in 1944 by Anton Bless and now in its third generation under Gregor and Valentin Bless, the company provides Spenglerarbeiten (sheet-metal work), metal and flat roofing, façade cladding, window sills, and VKF-certified lightning protection, alongside newer energy-related offerings including the Energiesparkönig consultation and Prefa solar-integrated roof systems. Its technology backbone is CAD-driven planning paired with an in-house workshop capable of prefabricating complex roof and façade components using CNC bending machines (up to 6.40 m), a long-sheet bending center, a slitting plant, Flexibend equipment for 3.0 mm steel, and a proprietary laser cutting system, before transporting finished assemblies to site for installation.

The company serves property owners, real estate developers, and general contractors across Canton Uri and adjacent regions of central Switzerland, with documented enterprise projects for Andermatt Swiss Alps AG, Max Felchlin AG (2021 Goldene Spenglerarbeit winner), Dätwyler Stiftung, and Pro Familia, as well as alpine infrastructure work for the Swiss Alpine Club (SAC). Revenue is earned entirely through custom-quoted, project-based contracts with no published pricing; supporting service lines include a Check-Up building inspection and energy advisory. The firm operates from a single integrated headquarters-workshop facility at Bärenbodenweg 17 in Erstfeld, holds ISO 9001:2000 certification (since 2001), and has been featured in Swiss trade publications including Baumetall, Gebäudehülle Schweiz, Hochparterre, and Sonntagszeitung.

The business model is a traditional regional craft services operation: project acquisition via direct B2B sales, on-site consultations, and a project portfolio website, with order intake handled by management (Gregor Bless is publicly listed as the primary point of contact). Materials of choice include Prefa aluminum systems (Dachplatten, Prefalz, FX 12 façade panels), Rheinzink, copper, chrome-nickel steel, and Eternit. Workforce stands at approximately 22–23 employees including three active Spengler apprentices, with the family brand anchoring both client trust and a Talentbox outreach program aimed at building the next generation of metalworking talent.
