Our History
1946
today
One big family since 1946
In 1946, Émile Blanc founded a cleaning and caretaking company in Lausanne. Buoyed by the boom in the construction sector in the 1960s, Blanc SA experienced rapid growth and naturally expanded its range of services.
Following this expansion, René Blanc led the company for many years with passion and determination.
In the early 1980s, the third generation took over and structured the company into specialized departments, led by brothers Marc-Olivier, Thierry, and Philippe Blanc.
Since 2017, the fourth generation has joined the family venture.
Today, Yaëlle Blanc ensures the preservation of the social and human ethics that have always defined the company, while bringing an environmental dimension that has become essential.
our core values
Blanc SA is a family-run business guided by a core value: respect for others and the environment. Our 500 employees share a common commitment to delivering meticulous work, drawing on a wide range of certified skills.
Protecting the planet is a cause close to our hearts, and one we champion wholeheartedly through eco-friendly and sustainable products, whilst ensuring efficient, rapid and high-quality services.
Naturally, all our services are tailored to provide unique flexibility and adaptability across all projects. Our team identifies every requirement so that we can respond effectively and thoroughly.
We condemn undeclared work in order to promote a framework based on ethics and integrity. Dans cette vision, nos collaborateurs et apprentis bénéficient de Conventions Collectives de Travail (CCT) des branches qui garantissent de bonnes conditions de travail et salariales. Under this approach, our employees and apprentices are covered by sector-specific collective agreements (CCTs) that guarantee good working conditions and pay. We are proud to be part of this community and to champion social and environmental values.
Our Mission
We provide our clients with personalized services, in compliance with high quality standards.
We promote the use of eco-friendly products, as part of our commitment to environmental preservation , and we act accordingly on a daily basis.
We are also committed to the well-being of our teams and the working conditions we offer them, and we value their expertise while encouraging the development of their skills, to ensure the satisfaction of all our stakeholders.
Our purpose
To give value to an essential profession, serving people, places, and the future.
Blanc SA is a family business active in industrial cleaning and professional maintenance. A demanding profession, often invisible, but essential to the smooth operation of organizations and the quality of life of users.
Our purpose is to ensure clean, safe, and sustainable environments, while creating quality jobs and caring for the women and men who bring our profession to life, today and tomorrow.
This purpose guides our decisions, our way of working with our clients, and our responsibility toward our employees, our partners, society, and the environment. It is part of our commitment formalized by B Corp certification since 2023, which we are renewing as part of evolving standards.
A clear direction, rooted in our profession
Professional cleaning is a sector subject to high demands for quality, safety, and reliability, with a high level of human intensity. Our commitment starts on the ground: responsible practices, safe working conditions, long-term client relationships, and constant attention to our environmental impact.
Our 2026–2031 strategy sets a clear direction: to develop Blanc SA in a controlled manner, by strengthening quality, teams, and sustainability. It is structured around five priorities:
- Clients — strengthen quality, retain our clients, and develop services
- Employees — stabilize teams and secure skills
- Management — ensure controlled and profitable growth
- Digitalization — structure and digitalize our processes by improving IT tools
- Sustainability — strengthen resilience and integrate ESG issues (environment, social, governance)
This approach allows us to reconcile performance, responsibility, and sustainability, in service of a more human, more sustainable, and better recognized profession.
