GUENEBAUT

What GUENEBAUT does

Guénebaut Frères is a privately-held, family-owned French manufacturer-installer of building closure and joinery products, headquartered in Thionville (Moselle department, Grand Est region). Founded in 1989 by brothers Jean-Marie and Michel Guenebaut, the company operates from a 2,800 m² fabrication workshop with 250 m² of offices at the Metzange industrial zone, complemented by a showroom on route des Romains in Thionville that has been open since 2000. It serves both professional buyers (building contractors, real estate developers, municipalities, retailers, automotive dealers) and individual homeowners across the Moselle department and the Luxembourg border area, deploying a mobile technical-sales force that conducts on-site project consultations.

The company's product portfolio spans 13 lines organized around three material platforms: aluminum joinery (windows, doors, verandas, storefronts, curtain walls), PVC joinery (windows, entry doors, shutters), and custom metalwork (steel railings, stairs, security doors, balustrades, gates), plus a motorization add-on category and industrial closure systems. Technical capabilities include thermal break technology for aluminum profiles, custom steel fabrication using Swiss-sourced Forster profile systems, and integration of branded partner platforms such as Schüco (primary residential systems provider), Technal, Kawneer, Hörmann, Verancial, Dierre, and Kline. The company holds Qualibat RGE certification, qualifying installation work for French government energy renovation subsidies.

Revenue is generated exclusively through custom quote-based projects combining design, fabrication, installation, and maintenance as a turnkey service. The go-to-market is direct: showroom walk-ins, inbound website/phone quote requests, and outbound on-site visits by technical-commercial staff. There is no e-commerce, no standardized pricing, no recurring subscription component, and no third-party distribution or reseller network. Approximately 20+ supplier-partner relationships (e.g., Condoor, ISEA, Malerba, Novoferm, Bandalux, Roma, Winsol, Lakal, AFCA, V2, Installux) underpin the inbound component supply chain, with final assembly, customization, and installation performed in-house.

Broad incumbents

• Lapeyre: French home improvement retailer and installer offering windows, doors, verandas, and interior fittings. Operates in the same renovation purchase occasions but at national scale across many more categories than Guénebaut.
• Hörmann: Major European manufacturer of garage doors, industrial doors, and access solutions. Guénebaut resells Hörmann products; broadly comparable scope on the industrial/garage door segment but at much larger scale.

Direct peers

• Bouvet: French manufacturer of aluminum doors, windows, and curtain walls with its own installation capabilities. Closely comparable B2B manufacturer-installer model with overlap in commercial façade and institutional projects.
• K-Line: French aluminum window and door manufacturer with an installer network. Closely comparable product portfolio (aluminum fenestration) and energy-efficiency positioning; serves as a direct upstream-adjacent competitor in the same French market.
• Maison du Fenêtre: French window, door, and home improvement specialist with a network of local showrooms. Comparable customer-facing model combining showroom-based consultation with custom fabrication and installation.
• Atlantem: French manufacturer of industrial closures, garage doors, and joinery products. Directly overlaps Guénebaut's industrial closure (fermeture industrielle) and garage door product lines.
• Vérandas Gustave Rideau: French veranda and conservatory manufacturer-installer network. Directly comparable on the vérandas/conservatory line of Guénebaut's portfolio, with a similar turnkey design-fabrication-installation approach.
• Tryba: French fenestration manufacturer-installer network with a comparable model of designing, fabricating, and installing windows, doors, and verandas. Directly comparable business model and target customer (residential renovation), though operating at national scale versus Guénebaut's regional scope.
• K par K: French PVC and aluminum window and door installer franchise with nationwide coverage. Directly competes for residential renovation customers with similar quote-driven, turnkey installation services.

Others

• Schücco: Major German aluminum and PVC systems supplier that is Guénebaut's primary systems partner. Upstream supplier rather than direct competitor, but its profile systems shape Guénebaut's product offering and competitive positioning in the French fenestration market.
