What Maison Janneau does

Maison Janneau is a French bespoke window and door manufacturer founded in 1973, operating manufacturing facilities in the Loire Valley and serving luxury residential, historic preservation, and cultural-heritage clients across France, the United States, Switzerland, Ireland, and the United Kingdom. The company crafts fully custom-made windows and doors in four noble materials — French oak and exotic woods, steel, bronze, and aluminum — organized into five named collections: Versailles (traditional wood), Lafayette (contemporary wood with tilt-and-turn), Eiffel (hand-welded steel), Rodin (handcrafted bronze with patina), and Montparnasse. Each unit is made to measure with no minimum order quantity, supporting customization of shape, size, glazing (Low-E double/triple), hardware, and 300-micron exterior coatings with a 12-year warranty.

The core technology stack combines traditional French artisanal joinery (espagnolette and cremone restoration, gueule de loup sash design, bronze patination) with modern manufacturing methods including 3D scanning and CNC precision machining. Products meet US NFRC certification and European thermal/acoustic standards through thermal break steel profiles, low-emissivity glazing, and gas-filled panes. Revenue is generated through one-time bespoke product sales, complementary hardware sales, and an ancillary French real estate service for international château buyers. Pricing is fully quote-based and consultative, with no published price lists. Distribution runs through direct enterprise field sales, the Austin, Texas U.S. showroom (opened 2024), a nationwide certified installation partner network, trade referrals from architects and designers, and European direct sales channels. Marketing relies on content (blog, photo gallery, YouTube), organic social (Instagram, LinkedIn, Facebook, Houzz), earned trade press coverage (Architect's Newspaper, Furniture Today, Milieu, Austin Home), and affiliations with AIA Austin and the Institute of Classical Architecture & Art.

Others

• Panaget: Established French oak flooring manufacturer partnered with Maison Janneau on coordinated interior packages. Closest material and aesthetic peer within the complementary ecosystem rather than direct competition.
• Atelier Métivier: French heritage restoration workshop that collaborated with Maison Janneau on the Plessis-Bellevue Manor restoration. Adjacent rather than competing; shares the same customer base in the heritage preservation channel.

Direct peers

• Hope's Windows: US-based heritage steel window manufacturer specializing in custom hot-rolled steel windows and doors for landmark and luxury projects. Closest US domestic alternative to Maison Janneau's steel windows.
• Crittall Windows: British heritage steel window manufacturer with a near-identical proposition: handcrafted, historically authentic steel (and now steel-and-wood) windows for luxury residential and heritage projects. Direct competitor in the same architectural specification channel.
• Loewen Windows: Canadian luxury custom wood window and door manufacturer serving high-end residential and historic projects across North America. Comparable on bespoke wood windows for architects and luxury homeowners.
• Brombal: Italian/US maker of custom steel, bronze, and brass windows and doors for luxury residential and commercial projects. Comparable on multi-material bespoke offerings and high-end pricing.

Broad incumbents

• Andersen Windows: Mass-market US window giant with custom and luxury lines (e.g., E-Series). Overlaps with Maison Janneau only at the very high end, but represents the scale alternative in the same customer set.
• Pella Corporation: Major US window and door manufacturer with custom wood and luxury offerings. Competes in the broader residential window category but does not specialize in the heritage French aesthetic niche.
• Marvin Windows and Doors: Large US premium window manufacturer offering custom and standard wood, clad-wood, and fiberglass products. Competes in the upper end of residential but with much broader product breadth and dealer network.

Regional players

• Steel Window Association: UK trade body representing heritage steel window manufacturers. Represents the cluster of UK-based direct competitors to Maison Janneau's steel window product line in the European heritage market.
