A Cleaner Heerlen: 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 well-versed in all standard cleaning tasks. Offices, vacation parks, schools, commercial buildings, student housing, etc., are their daily work environment. The Masters are trained for more specialized and demanding cleaning tasks. Finally, the Profs are trained for highly specialized work, such as crime scene cleaning at the sites of murder and other crimes, deaths, and suicides, as well as dealing with the odor of decomposition, trauma, and biohazards. They, too, are available 24/7 to provide immediate assistance anywhere in the Netherlands.

Owners of 12BClean

We'd like to get started working for you

Nice to meet you. We are Jack Oosterwaal and Michael de Bruine, both founders of 12B Clean, the cleaning company serving Heerlen and other areas. We’ve been inseparable in business for years. We once shared a dream: to start our own company in the cleaning industry. We wanted to approach it much better, much more comprehensively, and much more humanely than any other company. If you want something, you have to go for it—and here’s the result. Our cleaners are well compensated, receive training and recognition, and go to our clients with diplomas in hand.

They value intelligent and skilled people in their workforce. Together, we’re experts in every aspect of the cleaning industry—from routine cleaning to specialized tasks. And we offer all of this at a highly competitive price. With effective organization, this is a win-win model for everyone involved.
