MAISON - NETTE

What MAISON - NETTE does

Maison-Nette s.a. is a Belgian façade renovation company founded in 1974 by Paul and Anne-Marie Maréchal in Jupille-sur-Meuse (Liège), Belgium. The company operates a sales-led services model targeting private homeowners, commercial enterprises, property managers (syndics), religious and heritage buildings, and public institutions across the Wallonia region. Its service portfolio is organized into three pillars: façade cleaning (chemical cleaning, high-pressure cleaning, hydro-sanding, and hydro-pneumatic grésage), façade protection (anti-pigeon treatment, waterproofing/hydrofugation, and render treatment), and finishing and coating (repointing, lime application, and exterior painting). The company also offers general contractor coordination for multi-trade projects by leveraging its owned scaffolding inventory.

The company has roughly 10+ employees and completes over 100 construction projects per year within a 150 km radius from its headquarters at rue Charlemagne 18-20 in Jupille. Maison-Nette owns over 10,000 m² of scaffolding equipment, reportedly the only company in the province of Liège with its own scaffolding inventory, which provides scheduling autonomy and the ability to coordinate scaffolding use with other trades. It holds Walloon Region public procurement agréments (CAT D21 Class 3 for façade construction and D24 Class 1 for masonry), enabling tender participation for government and public institution projects.

The business is family-owned, with second-generation director Benoît Maréchal having bought out his parents' shares in 1996. Maison-Nette is a private Société Anonyme with no external investors, no funding rounds, and no disclosed revenue. Pricing is quote-based, with free estimates provided after mandatory on-site visits. Distribution is direct-to-customer via phone, website contact forms, and public procurement tenders. Marketing relies on word-of-mouth referrals, a corporate website, and a Facebook page. The company has been recognized with a 2009 Prix de l'Urbanisme nomination from the Ville de Liège.
