Activ'expertise is a national network of 140 firms and more than 200 property diagnosticians who intervene during the different stages of a property's life (sale, rental, construction, renovation), supporting both owners and real estate professionals.

Beyond the regulatory diagnostics in force (Carrez law, Boutin law, asbestos, lead, termites, ERP, DPE, gas and electricity), our members are trained and technically supported to provide a global and realistic vision of the properties diagnosed.

Our network is distinguished by the human quality of its members, by the values ​​that bring us together (professionalism, mutual assistance and pleasure), and by the three pillars of our service offer: responsiveness, quality of reports and post-diagnostic follow-up.
