Home decontamination in Paris goes beyond simple cleaning: it aims to completely eliminate biological, chemical or infectious contaminating agents present in an apartment or house. Défi Clean carries out decontamination of Parisian homes in all sensitive situations: after death, unsanitary homes, Diogenes syndrome, viral or bacterial contamination.

Decontamination vs Disinfection: What’s the Difference?

Disinfection reduces microbial load on surfaces to an acceptable level. Decontamination aims for the total elimination of pathogens and contaminating matter, including in porous materials and building structures. Decontamination is therefore the most demanding step, reserved for high-risk situations: late discovery of death, extreme unsanitary conditions, contamination by biological waste, severe pest infestation.

Decontamination After Death

When a death occurs in a Parisian apartment and the body is discovered late, decomposition generates intense biological contamination. Our protocol includes:

• Removal and treatment of biological waste (clinical waste)
• Chemical decontamination with broad-spectrum biocides
• Air remediation (nebulisation, ozone treatment)
• Treatment of porous surfaces (floors, walls, materials)
• Property restoration after decontamination

Unsanitary Home Decontamination

An unsanitary property poses serious health risks. Decontamination involves several steps:

• Clearance and removal: sorting objects and effects, removal of waste and bulky items, clearing accumulations.
• Pest control and disinfestation: treatment of pest infestations (rats, cockroaches, bed bugs, fleas).
• Biological disinfection and decontamination: elimination of bacteria, viruses, spores and pathogens.
• Anti-mould treatment: neutralisation of fungi and mould.
• Remediation: full sanitary restoration of the property.

Steps in Professional Decontamination

1. Diagnosis and risk assessment: identification of contaminated areas, evaluation of health risks.
2. Site securing: appropriate PPE worn throughout, work area marked off.
3. Removal of contaminated waste and materials: sorting, packaging and disposal via approved channels (clinical waste, recycling centre).
4. Deep mechanical cleaning: enzymatic detergents on all soiled surfaces.
5. Chemical decontamination: application of biocides by spraying, nebulisation or atomisation.
6. Air remediation: ozone treatment or nebulisation of active agents.
7. Quality control and certificate: verification of results, issue of a certified decontamination certificate.
