Every single cleaning technician that works for us is gone through a vetting and screening process. They are careful, especially around fragile objects, and will absolutely not open rooms with closed doors, closets, cabinets, or drawers without prior permission. Of course, accidents may occur, so if you do have irreplaceable items, they should be placed in areas where the cleaning technicians are not allowed. You should always secure your valuables, such as jewelry, plus keep your weapons and cash out of sight.
