Full Story

Background & Opportunity

Fenêtres Fermetures Du Doubs shows how a local building-services company can strengthen its market platform through several connected moves without claiming an unverified financial turnaround. Before 2021, the company operated under the name FENETRES DU DOUBS and was registered in Quingey. Public registration information identifies its creation on 1 April 2010 and its activity in timber and PVC joinery. The documented organisational turning point occurred on 1 February 2021. The company changed its name to FENETRES FERMETURES DU DOUBS and moved its registered address and operating location from 18 Grande Rue, Quingey, to 1 ZAE Combe Parnette in Lavans-Quingey. This created a clearer base for a broader local and regional proposition. The company’s stated offer now extends beyond a narrow window category. It covers PVC, aluminium, timber and composite windows and doors, shutters, garage doors and verandas. The target customers include individuals, professionals and local public institutions. The company presents a one-stop process covering assessment, guidance, customised product sourcing and installation, and states that installation is not outsourced. Its website says it works on both renovation and new-build projects and reports service coverage including Besançon, Pontarlier and Dijon. The positioning is supported by two documented external relationships. FenêtréA’s official Expert Conseil directory lists Fenêtres et Fermetures du Doubs, its address, product categories and manager Sébastien Boillot. Qualibat records RGE qualifications for exterior-window supply and installation, awarded on 8 November 2024, and roof-window work, awarded on 19 September 2025. A certificate issued on 24 September 2025 records an average workforce of 19 and is valid until 17 November 2026. Separately, the company website reports 18 employees. Those numbers should remain separate because they have different sources, dates and definitions. The business is still operating, but the public evidence does not show comparable revenue, profit, order volume, conversion or installation-capacity data before and after the move. The defensible conclusion is therefore not that relocation caused growth. Rather, the company assembled a stronger platform for regional installation work by combining a new identity and site, wider products, a manufacturer partnership, RGE credentials and controlled delivery.

Original Problem / Model

The original model was a Quingey-based timber and PVC joinery business operating as FENETRES DU DOUBS.

Turning Point

The legal name and registered location changed on 1 February 2021.

Core Decision

The new base is ZA Combe Parnette in Lavans-Quingey.

Execution / Model / Acquisition Changes

The offer expanded across windows, doors, shutters, garage doors and verandas in several materials.

Measurable Results

FenêtréA partnership and Qualibat RGE qualifications added documented trust and market-access signals.

Lessons

The platform is stronger, but public sources do not prove a revenue or profit increase.

A one-stop service from assessment through installation, with installation not outsourced.

Deep Analysis

Option B best matches the verified evidence. The 2021 legal-name change and move to Lavans-Quingey established a new operating base. Broader coverage of windows, doors, shutters, garage doors and verandas supports a wider customer proposition, while FenêtréA’s Expert Conseil listing adds a documented manufacturer relationship. Qualibat RGE qualifications for exterior and roof windows can strengthen trust and access to renovation-related demand. The stated one-stop, non-outsourced installation model also supports control over delivery. However, this is a capability and positioning case, not proof of financial success: public sources do not provide comparable revenue, profit, order or conversion data.

Turning Point

On 1 February 2021, the company changed its name and moved from Quingey to ZA Combe Parnette in Lavans-Quingey. It later operated as a FenêtréA Expert Conseil partner and held relevant Qualibat RGE qualifications.

Discover4/5

The evidence shows a legal relocation, rebrand and expansion in the company’s stated service proposition.

Analyze4/5

RGE credentials, partnership status and non-outsourced installation support trust and delivery control, but financial impact is unverified.

Execute4/5

The company broadened categories, retained one-stop delivery and built documented certification and partner signals.

Decide4/5

The most evidence-based decision is to combine these reinforcing moves rather than rely on rebranding alone.

Create4/5

Create a regional installation platform that joins customised advice, product breadth, certification and controlled delivery.

Positioning and capability can be documented even when financial outcomes cannot. Separate verified changes from unproven performance claims.
