About Us

We claim to be the cleanest all-around cleaning company in the country. And we live up to that claim every day. Our clients can attest to that.

A “12BCleaner” is a high-quality employee certified by us

At 12B Clean, the employees form a large, strong, and close-knit team. The more than 160 employees are divided into three groups. This allows everyone to contribute in their own field as a “Worker,” “Master,” or “Prof.” You don’t receive these titles just like that, by the way; 12B Clean employees only earn them after they’ve been trained for their role, have gained extensive practical experience, and have proven they can perform high-quality work.

With their certification of expertise in hand, the team at 12B Clean is ready to get to work for you. They are experts in all aspects of facility, industrial, and specialized cleaning services. As a result, clients always deal with specialists in the field. And that benefits the quality of the work. Expert cleaning and the use of the right materials extend the lifespan of buildings and equipment. Moreover, a clean environment literally contributes to a healthier work environment, which in turn boosts productivity.

A clean work environment leads to a better work atmosphere, happy employees, and higher productivity.

From Office Cleaning to Crime Scene Cleaning

At 12B Clean, we don’t shy away from anything—and I mean absolutely anything—when it comes to cleaning. Our three divisions are staffed by intelligent and highly trained people who know exactly what is expected of them.

The Workers are experts in all standard cleaning tasks. Offices, schools, healthcare facilities, vacation resorts, commercial buildings, student housing, and more are part of their daily routine. The Masters are trained for more specialized and demanding cleaning tasks. These include heavily contaminated buildings, hoarding cleanup, fire and water damage, rat infestations, bird droppings, and more. The Profs , finally, are trained for highly specialized work, such as crime scene cleaning at the sites of murder and other crimes, deaths and suicides, cadaver odor, trauma, and biohazards. They, too, are available 24/7 to provide immediate assistance anywhere in the Netherlands.

All employees (more than 160 of them) know their roles within the company and have been specially trained and well-educated for them. They work with love and passion for the cleaning trade, don’t watch the clock, and don’t go home until the job is 100% done.

  • We always stop by (with no obligation) to thoroughly assess the situation.
