BRETAGNE DIAGNOSTICS

What BRETAGNE DIAGNOSTICS does

BRETAGNE DIAGNOSTICS is a privately-held French société à responsabilité limitée (SARL) founded in 2007 and headquartered in Ambon (Morbihan), operating across the Brittany region and Loire-Atlantique. The firm specializes in legally-mandatory real estate diagnostics required for property sales and rentals in France — including the Diagnostic de Performance Énergétique (DPE), asbestos, lead paint, gas, electrical, termite, surface measurement (Loi Carrez / Boutin), and environmental risk (ERP/ESRIS) reports. Its certified technicians (accredited by ICERT and members of FNAIM) are dispatched on-site and deliver reports within 48 hours of intervention.

The company has extended beyond the standard transaction-diagnostic core into specialized construction-compliance work: infiltrométrie (blower-door air tightness testing), étanchéité à l'air assessments, RT2012 thermal conformity attestation (offered as a bundled "Pack RT2012"), DPE Mention Tertiaire for commercial buildings, and pre-renovation/demolition asbestos inspections. This positions the firm to capture revenue from construction firms and demolition contractors in addition to its traditional base of property sellers (propriétaires vendeurs) and landlords (bailleurs).

Commercially, BRETAGNE DIAGNOSTICS runs a direct-to-consumer professional services model. Customers contact the firm via phone or website to request a free quote; technicians travel to the property; reports are delivered digitally within 48 hours via a secure server accessible 24/7, with online payment supported. The firm operates five regional agencies (Ambon, Saint-Jacques de la Lande, Pontivy, Redon, Grandchamps des Fontaines, Dol de Bretagne) covering departments 22, 35, 44, and 56, with marketing executed primarily through location-specific local SEO pages on diagnostic-bretagne.fr. Revenue is generated from per-diagnostic professional service fees, with bundled packages for complete property assessments and the Pack RT2012 for construction clients.
