Crime scene cleaning Paris 12th: prepare the threshold after access is confirmed
Défi Clean begins only once investigative examinations are complete and access has been authorised by the person or authority empowered to do so. In a ground-floor home, the doorway may lead directly onto a route used by residents or pedestrians. Preparation therefore includes protecting and marking out the threshold and defining an indoor equipment area before working movements begin.
Permission to enter establishes where the proposed work may take place; it does not make the surrounding passage available for equipment or storage. The scope is described without discussing the events. A place for setting down equipment is agreed inside the authorised area, and threshold arrangements are established before transfers begin. If that preparation cannot be accommodated, the working conditions are reviewed.
- Confirm release before preparing the area
- Protect the threshold before equipment transfers
- Place equipment within the authorised interior
- Preserve circulation outside the working entrance
Prepare the doorway within the confirmed boundaries
Before setting up the work
- Confirm completion of the investigative examinations
- Check permission for the relevant spaces
- Identify the boundaries of authorised access
- Specify movements of belongings already accepted
At the entrance and threshold
- Examine circulation immediately outside the door
- Plan protection appropriate to the threshold
- Define marking that preserves existing passage
- Prepare crossings for the packaged equipment
Inside the equipment area
- Select an authorised indoor location
- Limit equipment to the agreed requirements
- Keep excluded areas free of equipment
- Plan removal of the working installation
When the authorised door is everyone’s way through
In the 12th, a ground-floor doorway may open straight onto a through courtyard or the street. The entrance selected for the work then meets a passage still used by residents, neighbours or pedestrians. Authorisation to enter the home does not turn that circulation into a working area. Before equipment transfers, we prepare threshold protection and marking suited to the planned crossings, within the permitted boundaries. The arrangement identifies the working entrance while preserving movement outside it, rather than creating an obstacle across the doorway. An indoor area is selected for setting down equipment so that it does not accumulate in the passage. Its location is part of the preparation: it must be accessible and accepted, without an assumed right to move belongings or use a space excluded from the agreement. The outside route remains distinct from the interior setup.
This preparation starts only once investigative examinations are complete and access has been authorised by the person or authority empowered to do so. If the indoor location cannot accommodate the equipment, the arrangement is reviewed before transfers; the passage does not become an automatic alternative. The status of elements around the threshold is checked through the applicable documents and relevant parties, without deciding ourselves what is private or communal. Défi Clean does not issue any permissions required for using public space. Packaged equipment and closed waste containers help limit what is visible during crossings, without promising an unnoticed visit. Explanations about the work remain with the authorised person, and the circumstances are not discussed with neighbours while the entrance is being used.
From confirmed access to removal of the working setup
Confirm the prerequisites
Completion of investigative examinations and access authorised by the empowered person or authority are checked before any preparation begins.
Describe the spaces
Areas to be treated, exclusions and permitted movements of belongings are identified so that preparation stays within the accepted boundaries.
Prepare the threshold
Protection and marking are established before equipment transfers, with an arrangement that preserves the surrounding circulation.
Set up indoors
Equipment is placed in the agreed interior location, without storage in the outside passage or use of a space not covered by permission.
Perform the operations
Work follows the accepted description; any need for more space or additional handling is reported before the scope is changed.
Remove the setup
Equipment and protection are taken out under the planned arrangements, then completed operations and remaining limitations are reported.
What defines the cleaning and entrance arrangements
- Prior confirmation of authorised access
- Spaces released for the proposed operations
- Accessible materials and accepted cleaning tasks
- Threshold requiring protection before transfers
- Circulation outside the relevant doorway
- Indoor space available for equipment
- Movements of belongings expressly permitted
- Containment needed for planned outgoing transfers
The quote records the operations included and the conditions needed to perform them, including threshold preparation and indoor equipment placement. Access permission does not cover neighbouring areas merely because they adjoin the entrance. If an installation detail remains unresolved, the affected stage waits for clarification. Inaccessible surfaces stay excluded, and observed deterioration is reported without guaranteeing habitability, disappearance of an odour or an original appearance.

Questions about release, access and the shared passage
Can the entrance be prepared before investigative examinations are complete?
No. Nothing begins until the examinations are complete and access has been authorised by the empowered person or authority. That requirement also applies to preparing the threshold and installing equipment inside the relevant premises.
Is a key handed over by a relative enough to start the work?
No. Having a key confirms neither completion of the examinations nor permission for the proposed operations. Those conditions must be checked with the empowered person or authority before any preparation or working movements begin.
Can equipment wait outside the door if there is insufficient space inside?
No. The outside passage is not used as the default equipment area. If the selected indoor location is unsuitable, the arrangement is reviewed and any necessary permissions clarified before equipment transfers take place.
Does marking the threshold allow the team to reserve part of the pavement?
No. Marking for the planned crossings does not authorise occupation of public space. The applicable conditions must be checked with the relevant parties; Défi Clean does not issue those permissions or treat them as automatically obtained.
Who establishes whether an element beside the doorway is private or communal?
Its status must be checked in the applicable documents and with the relevant parties. We do not infer it from the element’s position near the entrance; permission for any operation affecting it must be clarified before that work is included.
What happens to papers encountered within the authorised areas?
Papers encountered are set aside according to the authorised person’s instructions, without guaranteeing that every document will be found. Their presence does not authorise searching an excluded area or moving belongings beyond the accepted decisions.
Does the cleaning automatically include complete decontamination?
No. Decontamination follows assessment where an identified risk warrants a specific protocol and defined scope. The accepted cleaning does not guarantee habitability, disappearance of an odour or restoration of an old mark to its original appearance.
