Groupe Mathieu is certified by the APCHQ, which offers the Garantie Abritat (GA: abritat warranty) introduced in 2011, as well as the Garantie des maisons neuves (GMN: new home warranty). These two warranties not only protect consumer investments, but are also a pledge of professionalism and unquestionable construction quality. The company also holds “Master Builder” Diamond certification. According to the APCHQ, the Master Builder title constitutes a commitment to reliable and professional work, and corresponds to the number of consecutive years that builders have maintained a satisfaction rate greater than 97% since getting their GMN certification. Groupe Mathieu won this Diamond distinction in 2005 for its accomplishments over the last 30 years..
