Who are we?
Founded in Locronan in 1973, by a carpenter and his wife, Ronan and Monique Cadiou. Since 2007, it's the turn of the second generation to take up the torch of this family business that has become a flagship of the regional industry. Family values are deeply rooted in our genes: the transmission of know-how, human relationships and love of the craft. If these prides are engraved in marble, the company has never stopped evolving to adapt to the times and the expectations of our customers.

Our ESG commitments
ESG actions
Our ESG commitments
ESG actions (environment, social and governance) are thus put in place with the aim of promoting responsible and sustainable activity. Very committed to the inclusion of people far from employment, recruitment without CV based on aptitude tests has been in place for more than 10 years, for example. Quality of Life and Working Conditions (QVCT) actions are regularly carried out to improve the well-being of employees on a daily basis.
On the environmental front, following the completion of the latest Carbon Assessment, Maison Cadiou is working to align its decarbonization trajectory with the objective of the Paris Agreement through numerous actions carried out throughout the production chain: integration of low-carbon and recycled aluminum in production, eco-design of products, recycling of more than 90% of industrial site waste... Proof of its commitment, Maison Cadiou obtained the Bronze medal of Ecovadis certification in March 2024.
Led by the founder's daughter, Emmanuelle Cadiou, the eponymous house ensures that its policies and decisions are aligned with numerous high ethics in cooperation with its ecosystem (suppliers, partners, local authorities, customers) thus promoting stakeholder confidence and ensuring efficient and responsible management of the company.
