Spiess

What Spiess does

Glas Spiess GmbH is a family-owned German handicraft company founded in 1996 and headquartered in Timmendorfer Strand, operating under the brand Spiess with a secondary trade name Handwerkswerk. The company combines three craft disciplines — steel construction (Stahlbau/Metallbau), carpentry (Zimmerei), and glazing (Glaserei) — under one organizational roof, offering integrated project delivery for residential and commercial customers in northern Germany. This multi-trade model, strengthened by the 2012 acquisition of Metallbau Falbe, is positioned as the company's core differentiator: cross-trade coordination at interface points is marketed as delivering time and cost savings relative to single-trade contractors.

The service portfolio spans carpentry and interior finishing (roof structures, carports, drywall, roofing), building elements (windows, doors, facades, conservatories in plastic, aluminum, and wood), all types of glazing (repairs, showers, full-glass systems, auto glass), complete residential renovations with KfW energy efficiency funding support, balcony railings, fences, stair systems, outdoor wood materials, and sun protection systems. A 2024 addition is the VELUX Dachfenster-Konfigurator embedded on the company website, which enables customers to configure personalized roof window solutions and request quotes directly from Spiess.

The business operates a project-based, quote-driven revenue model with one-time project fees for construction, repair, and renovation work. Customers are primarily residential homeowners, with a secondary segment of commercial building owners. The company employs 70 people and generates annual revenue of €7 million, serving a regional market without disclosed geographic expansion plans, external investment, or public listing. Distribution is direct via the website, phone, and on-site delivery, with no marketing channels explicitly identified.

Expansion highlights3 records

Regional players

• Holzbau Schmid GmbH & Co. KG: Regional German carpentry and timber construction firm. Comparable to Spiess's Zimmerei und Innenausbau offerings (Dachstühle, Carports, Trockenbau) but as a single-trade specialist without the integrated metal/glass capability.
• Metallbau Schröder GmbH: Mid-sized German steel/metal construction fabricator. Comparable to Spiess's Stahlbau and the legacy Metallbau Falbe business line, but lacking carpentry and glazing integration.

Broad incumbents

• Glas Trösch: Large European glass and glazing manufacturer/installer with broad building-envelope capabilities. Comparable as a glazing counterpart to Spiess's Glaserei line of business, though operating at vastly greater scale and across multiple countries.
• Saint-Gobain Glassolutions: German arm of Saint-Gobain providing processed architectural glass and glazing installation services. Directly comparable in product line to Spiess's Verglasungen aller Art offering, but with national footprint and corporate backing.
• Flachglas Wernberg: Major German glass processor and supplier of architectural glazing systems. Comparable to Spiess's glazing offering (curtain walls, facades, specialty glass) though positioned upstream as a fabricator rather than an installer.
• Bauhaus (Handwerkspartner-Netzwerk): Large German home-improvement and craft-services retailer with an extensive installer network. Competes with Spiess for residential renovation and window/door installation projects, albeit through an aggregated partner model rather than self-performed crafts.
• Hörmann KG: German building-element specialist (doors, frames, glazing systems) with national reach. Overlaps with Spiess's Bauelemente product line for residential and light-commercial projects.

Others

• VELUX Deutschland GmbH: Major roof-window manufacturer and Spiess's formal integration partner via the Dachfenster-Konfigurator. Functions as a lead-generation and brand-loan partner rather than a direct competitor, but a key ecosystem participant.
• KfW Bankengruppe: German state development bank administering subsidized energy-renovation funding. Not a competitor but a direct enabler of Spiess's KfW-supported Komplettsanierungen service; deeply relevant as the policy mechanism shaping demand.

Emerging players

• Biffar GmbH: Premium German manufacturer/installer of doors, windows, and conservatories. Comparable niche to Spiess's Wintergärten and Bauelemente offerings for high-end residential clients, though with a stronger premium-brand positioning.
