Property Decontamination in Paris

Our Property Decontamination Services in Paris

Decontamination must be organised according to the nature of the contamination, the affected areas and the condition of the materials. Before any treatment, we assess the required work and the precautions to be put in place.

Assessment of the Situation

The first step is to understand the origin of the contamination and identify the affected areas. This assessment determines the protocol and the resources required.

• Inspection of the rooms and surfaces concerned

• Identification of the source of contamination

• Location of inaccessible or severely deteriorated areas

• Evaluation of the level of clutter

• Identification of personal belongings to be preserved

• Analysis of access and handling constraints

• Determination of the protective equipment required

• Definition of the intervention protocol

This step helps distinguish recoverable surfaces from those too deteriorated to be cleaned and requiring removal.

Clearance and Removal of Contamination Sources

When waste, deteriorated items or contaminated matter are present, their removal is an essential preliminary step before surface decontamination.

Depending on the situation, we can organise:

• Identification and sorting of recoverable personal belongings

• Setting aside of important documents and objects

• Removal of waste and contaminated matter

• Clearance of unusable items

• Removal of overly deteriorated materials

• Protection of unaffected areas

Clearance can be organised in coordination with the occupant, their family, an authorised representative or the landlord.

Preliminary Cleaning of Surfaces

Thorough cleaning is necessary before any decontamination. Dirt, deposits and residue on surfaces can limit the effectiveness of treatment if not removed beforehand.

The intervention may include:

• Dust removal from accessible surfaces

• Floor cleaning

• Washing of walls and washable surfaces

• Degreasing of kitchen areas

• Cleaning of bathrooms and toilets

• Removal of ingrained residue

• Cleaning of doors, handles and switches

• Preparation of areas before decontamination

Decontamination of Surfaces and Contact Points

After cleaning, the affected surfaces are treated according to the identified risks and the nature of the materials.

• Floors and washable surfaces

• Kitchen areas and accessible appliances

• Bathrooms and toilets

• Door handles

• Light switches

• Worktops

• Recoverable furniture

• Frequently touched surfaces

• Areas contaminated by waste or biological matter

Treatment is adapted to the materials to limit the risk of damage. Some porous or severely deteriorated surfaces may not be fully recoverable.

Decontamination After Diogenes Syndrome or Domestic Neglect

In a heavily cluttered property, decontamination cannot generally be carried out properly while objects or waste continue to cover the surfaces. The intervention may therefore be divided into several stages.

• Identification of important documents and belongings

• Sorting with the occupant or their representative

• Gradual decluttering

• Removal of approved waste

• Intensive cleaning of cleared surfaces

• Decontamination of exposed areas

• Additional odour treatment when required

The work can be organised with the occupant, their family, a guardian, legal representative, landlord or authorised professional.

Decontamination After Pest Infestation

The presence of rodents, insects or pests leaves droppings, marks and contaminated areas. After the infestation has been treated, we can take charge of:

• Removal of accessible droppings and residue

• Removal of waste and debris

• Cleaning of thoroughfares

• Decontamination of soiled surfaces

• Cleaning of accessible storage spaces

• Reduction of residual odours

Decontamination complements pest-control treatment. It does not replace the elimination of entry points or the work required to prevent the return of pests.

Preparing the Property for Reoccupation or Works

An intervention may be requested before reoccupation, reletting, sale or renovation of a property.

We can organise the restoration before:

• The occupant’s return

• A new tenant moving in

• A check-in or check-out inspection

• Sale of the property

• Handover of the keys

• Work by another contractor

• Renovation work

Our assessment distinguishes the cleaning and decontamination operations completed from any repairs that may still be required.

Interventions in Parisian Shared Buildings

Parisian buildings often present specific constraints: narrow staircases, no lift, internal courtyards, restricted access or heavily used communal areas.

The work can include:

• Protection of access routes

• Handling adapted to narrow staircases

• Compliance with the building’s permitted working hours

• Coordination with the caretaker or building manager

• Reduction of disruption to neighbours

• Organised waste removal

• Discreet access to and from the property

Why Choose Défi Clean for Property Decontamination in Paris?

• Individual assessment: the protocol is determined according to the property’s actual condition and the source of contamination.

• Clearance before decontamination: sources of contamination are removed so that the treatment can be carried out under appropriate conditions.

• Complete service: sorting, clearance, deep cleaning, decontamination and odour treatment can all be coordinated.

• Respect for personal belongings: documents, keepsakes and important possessions can be set aside before clearance begins.

• Discretion: we organise the work to limit exposure of the situation to neighbours wherever possible.

• Adaptation to Parisian buildings: the floor, lift, courtyard, staircase and parking conditions are all considered during preparation.

• Single point of contact: communication can be centralised through the occupant, family, landlord, building manager or authorised representative.

• Detailed quotation: the required operations are clearly specified according to the property’s condition.

• Clear distinction between cleaning and repairs: we identify surfaces and fixtures that cannot be restored through cleaning alone.

Tax Credit and Tax Benefits

Certain household-maintenance services performed in a private home may qualify for a tax credit equal to 50% of eligible expenses, subject to the limits and requirements set by French regulations.

Eligibility depends in particular on:

• The exact nature of the service

• Where the work is performed

• The beneficiary’s tax circumstances

• Whether the service provider meets the applicable regulatory requirements

• Annual spending limits

• Any financial assistance already received

• The information stated on the invoice

For property decontamination, not every part of an intervention necessarily receives the same tax treatment. Eligibility must be checked according to the invoiced services and the regulations in force.

To check the current requirements, consult the official French government page on the tax credit for employing a worker at home.

Indicative Cost of Property Decontamination in Paris

The cost of decontamination depends on the condition of the property and the work required. A targeted intervention does not require the same organisation as a full restoration after severe deterioration or an extended period of vacancy.

The quotation takes account of:

• The size of the property

• The number of rooms requiring treatment

• The level of dirt

• The type of contamination

• The extent of the sanitary risk

• The preliminary cleaning required

• The volume of waste to be removed

• Sorting and clearance requirements

• The products and equipment required

• The protective measures to be put in place

• Any necessary odour treatment

• The presence of pests

• The number of operatives required

• The estimated duration of the work

• The floor and availability of a lift

• Parking and handling constraints

• Waste-removal and processing costs

Photographs can help with an initial assessment. For complex situations, a more detailed evaluation may be required before the final scope of work can be established.

A fixed price cannot be provided without understanding the condition of the property. The quotation clearly distinguishes between sorting, clearance, cleaning, disinfection, decontamination and any additional treatments.
