Maison Sur

What Maison Sur does

MaisonSûr is a French home-improvement contractor headquartered in Anglet, France, founded in 2000 as a family business serving residential homeowners across southwest France. The company operates six regional agencies in Bayonne, Bordeaux, Marmande, Montauban, Périgueux, and Toulouse, with more than 100 qualified collaborators delivering on-site services across five interconnected categories: energy (solar panels, battery storage, EV charging, heat pumps), insulation (attic, roof, exterior walls, ventilation), roofing and carpentry, facade renovation, and moisture/humidity treatment.

The company's service model is project-based installation and renovation work, with a free home assessment (bilan gratuit), free energy study (étude énergétique gratuite), and free humidity diagnostic offered as no-obligation entry points. Field technicians serve as the primary sales interface, supplemented by inbound toll-free phone, email, and website quote forms. MaisonSûr combines its own roofing and framing expertise with energy installation — a structural integration that pure-play solar installers cannot offer — and operates an integrated technology stack through partnerships with Enphase (Platinum Installer status, IQ8 microinverters, IQ Battery 5P, IQ EV Charger 2), DualSun (photovoltaic panels), Airwell (AURA heat pumps), Mylight150 (virtual battery), and Eoletec (VPH ventilation).

Revenue is generated primarily through one-time installation fees per project, with limited optional maintenance contracts providing any recurring revenue. The company holds state-recognized certifications including RGE QualiPV (Bât and 36), Qualifelec IRVE, QualiPac, and Qualibat, which are prerequisites for French customers to access government energy-efficiency subsidies. An official EDF 'Partenaire Économies d'Énergie' agreement extends the demand-generation footprint beyond direct field sales. Since founding, MaisonSûr reports 30,000 customers served, 50,000 construction projects completed, and 110,000 free home assessments conducted, with a 4.4/5 verified review rating across 282 reviews. The legal entity is MAISONSÛR SAS with €100,000 share capital; Fabrice Vigneau is the Directeur de la publication.
