In addition, this sector includes, for example, the accommodations of residential groups for the disabled and mentally handicapped. Thanks to many years of experience in this medical sector, our employees can deal well with residents or patients themselves. Requesting a "Declaration of Good Conduct" (VOG) for cleaning for these specific projects is no problem for us.
