The company Modulancy S.A. was established by Mr. Léon Monico in January of 1971 in Geneva, Switzerland. Small family business, Modulancy S.A. employed as much as 60 people in 1977 during the great construction development in Geneva. From its foundation until the mid-eighties, the bulk of the mandates received in plaster-work and painting concerned new buildings. Since then, a reconversion was carried out and currently most of the work done concerns renovations and transformations. It was in this spirit that the company Modulancy S.A. decided to formalise its management by submitting a request to ISO. The company has then been successfully certified ISO 9001-2000 March 25th 2003, March 25th 2005 and March 25th 2008.

Today, after facing more than twenty years of the largest real estate crisis it has witnessed, the company still delivers high quality mandates. It has kept its small structure dedicated to efficiency. Modulancy S.A. stays above all, a family owned company with an ethic oriented towards high qualifications when it comes to choosing collaborators. Mr. Pierre-Yves Monico, son of the founding shareholder, after having helped M. Léon Monico for more than 15 years, has taken over the directions of the company.
