What is crime scene cleaning?
A crime scene — whether homicide, suicide or violent death — leaves significant biological traces:
- Blood and bodily fluids — often absorbed into porous materials.
- Tissue fragments — requiring certified handling and disposal.
- Post-mortem biological waste — classed as infectious clinical waste.
These materials present serious health risks and must be treated by certified professionals with the appropriate equipment and products. Crime scene cleaning takes place after the forensic police have completed their investigation and released the scene. Our company takes over from that call to carry out complete decontamination and restoration of the apartment, house or premises involved.
Our crime scene cleaning service in Paris
A seven-stage protocol, from securing the scene to the decontamination certificate.
Rapid response after police release
As soon as the police or gendarmerie releases the crime scene, Défi Clean can intervene. Our emergency service is available 24/7 across Paris and Île-de-France.
- Response within 24 hours
- Within 2 hours on request, subject to availability
1. Assessment and securing
Identification of all biological traces (blood, fluids, organic matter) and evaluation of health risks before any handling. The scene is secured and access restricted to our equipped technicians.
2. Collection and removal of biological waste
Blood, bodily fluids and biological fragments are packaged in DASRI containers and disposed of via approved channels, with full traceability of the disposal chain.
3. Deep mechanical cleaning
Removal of all visible and invisible traces using enzymatic detergents on every surface, including porous materials and hard-to-reach areas where fluids may have seeped.
4. Decontamination and disinfection
Application of virucidal and bactericidal biocides (EN 14476, EN 1276) across all surfaces, eliminating every pathogen present on the scene.
5. Odour treatment
Neutralisation of blood and decomposition odours using enzymatic treatment and/or professional ozone generators. Odours are removed at source, not masked.
6. Clearance of non-recoverable items
Mattresses, textiles and contaminated furniture are sorted, removed and disposed of through the appropriate waste streams.
7. Decontamination certificate
A certified document is issued at the end of the intervention. It is required by insurers, notaries and, in many cases, for the sale or re-letting of the property.

Frequently asked questions about crime scene cleaning in Paris
When can you intervene?
Only once the forensic police or gendarmerie have completed their investigation and formally released the scene. From that moment we can be on site within 24 hours, or within 2 hours on request subject to availability.
Does home insurance cover the cost?
In many cases yes: multi-risk home policies often include restoration after a violent death. We issue a detailed quote, an invoice and a decontamination certificate so the claim can be filed. Check the exact terms with your insurer.
Can the family be present during the intervention?
We advise against it, for both health and emotional reasons. A relative or building manager can hand over access and be briefed before and after the intervention. Everything is documented in writing.
What happens to contaminated furniture?
Mattresses, textiles and porous furniture that cannot be decontaminated are sorted, packaged and disposed of through the appropriate waste streams. Recoverable personal belongings are cleaned and set aside for the family.
Do you issue a certificate?
Yes. A decontamination certificate is issued at the end of every intervention. It is regularly required by insurers, notaries and buyers, and for re-letting the property.
