FINESTRA

What FINESTRA does

FINESTRA is a French exterior joinery and home envelope renovation company founded in 1994 and headquartered in Quimper, Brittany, operating as a SAS with €100,000 of share capital. The company employs 106 staff and runs a network of five physical agency/showrooms (Quimper, Brest/Guipavas, Lorient, Crozon, and the Nantes region) across Finistère, Morbihan, and Loire-Atlantique. Its core offering spans exterior carpentry — windows, entry doors, shutters, garage doors, gates and fencing, awnings, and bioclimatic pergolas — in PVC, aluminium, mixed alu/wood, and wood, alongside external thermal insulation (ITE) added in 2023. Products are sourced from certified French manufacturers and installed by FINESTRA's own salaried technicians using full-removal (dépose totale) methods, with the company holding RGE, Qualibat, QualiMarine, Qualicoat, Qualanod, CSTBat, NF, Cekal, and Origine France Garantie certifications.

The business generates revenue primarily through project-based, quote-driven installation fees for each carpentry or insulation job, supplemented since 2023 by a recurring after-sales service (SAV) with fixed per-intervention pricing (€90–€135 excl. VAT). All sales are direct, via in-person agency visits and on-site consultations by commercial technicians; there is no e-commerce, marketplace, or third-party reseller distribution. Customers access French government energy renovation subsidies (Ma PrimeRénov, ANAH, eco-PTZ) through FINESTRA's RGE certification, which functions as a key demand catalyst. Pricing is project-specific with occasional promotional discounts (e.g., 10% off pergolas in May–June).

The customer base consists of residential homeowners undertaking renovation, plus a smaller set of local businesses and artisan workshops, with named case-study customers all classified as SMBs. The company is a member of the Univerture network and cooperates strategically with Homanova in the Nantes region for integrated timber-frame and renovation work. FINESTRA is led by President Philippe Sellier, who personally engages with customers via Google review responses, and the company continues to expand geographically (Crozon in February 2026) while building new service lines.

Revenue model

1. Exterior carpentry product sales and installation: FINESTRA sells and installs exterior opening products (windows, doors, gates, shutters, garage doors, pergolas) directly to homeowners and businesses. Revenue is generated through one-time project fees that include both product supply and professional installation. This is the primary revenue stream.
2. Exterior thermal insulation (ITE) installation: Installation of exterior thermal insulation systems (insulation boards with rendering or cladding), often eligible for government subsidies (Ma PrimeRénov, ANAH, eco-PTZ). Revenue is project-based, including material and labour.
3. After-sales service and repairs: Dedicated repair and maintenance service covering all installed products (rolling shutters, doors, motorisations, terrace awnings). Service fees are charged per intervention: €90 excl. VAT for minor repairs/adjustments, €135 excl. VAT for maintenance up to 7 openings. Part of the newly created SAV department.

Scale indicators6 records

Recent moves10 records

Expansion highlights5 records

Broad incumbents

• K•LINE: Leading French aluminum window and sliding door manufacturer with a national dealer/installer network. Comparable to FINESTRA as a primary supplier of aluminum exterior joinery installed across France, though K•LINE controls the product IP while FINESTRA resells third-party brands.
• Lapeyre: Established French home renovation chain (windows, doors, kitchens, bathrooms, interiors). Overlaps directly with FINESTRA's window/door product line and also offers installation services nationwide, but operates at much broader scale across multiple home categories.
• Atlantem: French industrial group manufacturing windows, doors, garage doors, and roller shutters for the residential renovation market. Comparable to FINESTRA in product scope (exterior carpentry) and target end-customer, with a stronger manufacturing footprint and national distribution.
• Bel'M: French entry-door manufacturer and brand explicitly carried by FINESTRA. Comparable as a producer of the same aluminum/wood/PVC entry door range, with a national dealer network spanning the same installer-led go-to-market.
• Saint-Gobain Distribution Bâtiment: French distribution arm of Saint-Gobain supplying building materials through Point.P, Cedeo, and other networks to contractors including exterior joinery installers. Comparable as a major upstream supplier and indirect channel competitor shaping FINESTRA's procurement and customer acquisition environment.

Emerging players

• Profalux: French shutter and roller-blind specialist supplying renovation and new-build markets. Comparable to FINESTRA's volets category with similar coastal/renovation positioning, though more specialized and product-focused versus FINESTRA's broader opening portfolio.

Direct peers

• TRYBA: France's leading national window/door franchise network. Closely comparable to FINESTRA because both operate an installer-franchise model selling PVC, aluminum, and wood exterior joinery with in-house installation, vs. FINESTRA's regional direct agency model.

Others

• Reynaers Aluminium: European aluminum systems manufacturer for windows, doors, sliding systems, and facades. Comparable to FINESTRA's aluminum product range as a high-end systems supplier installed by similar project-based dealers across Europe.
• Somfy: Global leader in motorized openings and home automation, explicitly integrated with FINESTRA's domotics offering. Comparable as the upstream technology supplier for FINESTRA's connected shutters, gates, and pergolas, rather than a direct competitor.
• Homanova: Nantes-area timber-frame house, extension, and ITE specialist operating as a core partner of FINESTRA in Loire-Atlantique. Comparable as an adjacent regional contractor offering complementary envelope services and sharing customer leads with FINESTRA.
