Professional Disinfection Services in Western Switzerland
When standard cleaning is not sufficient to neutralise biological, chemical or infectious hazards, professional disinfection is required. Disinfection goes beyond surface cleaning: it aims to eliminate or reduce to an acceptable level all pathogenic microorganisms — bacteria, viruses, fungi and spores — on surfaces, in the air and in water systems.
SOS Nettoyage provides certified disinfection services throughout Western Switzerland, covering medical facilities, businesses, post-disaster environments, contaminated premises and any situation requiring a validated decontamination protocol. Our technicians hold the required authorisations and use hospital-grade disinfectants registered under Swiss biocide legislation.

Medical Facility Disinfection
Healthcare environments carry a high risk of healthcare-associated infections (HAIs). Rigorous and regular disinfection is not a luxury — it is a legal and ethical obligation. SOS Nettoyage provides disinfection services for all types of medical facilities in Western Switzerland:
- General practitioner and specialist practices: consultation rooms, waiting areas, sanitary facilities, door handles, light switches
- Dental practices: treatment rooms, dental unit water lines, instrument preparation areas
- Physiotherapy and rehabilitation centres: treatment tables, gymnastic equipment, floor surfaces
- Private clinics and day surgery units: operating theatres, recovery rooms, patient rooms
- Laboratories and analysis centres: benches, equipment surfaces, biosafety cabinets
- Pharmacies: dispensary counters, storage areas, sanitary facilities
- Home care and nursing homes: individual rooms, shared sanitary facilities, communal areas
Our medical disinfection protocols distinguish between cleaning (physical removal of soiling), disinfection (reduction of microbial load by a validated factor) and sterilisation (complete elimination of all life forms), and apply the appropriate level to each area of the facility.
Post-Disaster Disinfection
Disasters — flooding, fire, burst pipes, sewage backflow — leave behind biological and chemical contamination that requires specialist intervention before the premises can be safely reoccupied. SOS Nettoyage works in close coordination with our fire and disaster damage cleaning teams to provide a complete restoration service.
Flooding and Water Damage
Floodwater contains sewage bacteria, mould spores, chemical pollutants and sediments. After water removal and structural drying, thorough disinfection is essential:
- Surface disinfection: all walls, floors and structural elements in contact with water
- Anti-mould treatment: application of fungicidal agents to prevent mould proliferation in residual moisture
- HVAC disinfection: ventilation ducts and air handling units that may have drawn in contaminated air
- Air treatment: HEPA air scrubbers to remove airborne mould spores and bacteria
Fire and Smoke Damage
Smoke deposits and soot contain carcinogenic polycyclic aromatic hydrocarbons (PAH), heavy metals and toxic combustion residues. Disinfection after fire damage includes:
- Decontamination of smoke-affected surfaces with appropriate chemical agents
- Ozone treatment to neutralise persistent smoke odours at a molecular level
- Air quality testing before reoccupation
Disinfection After Death
The discovery of a body after an extended period, or death in circumstances involving significant biological contamination (haemorrhage, decomposition), requires intervention by trained specialists. This is one of the most sensitive disinfection scenarios: our teams operate with full discretion, appropriate PPE and validated biocidal protocols.
The intervention includes:
- Removal of all biological matter following legal requirements and waste disposal regulations
- Decontamination of all affected surfaces: floors, walls, furniture, mattresses
- Odour neutralisation: thermal fogging with odour-eliminating agents and ozone treatment
- Air sampling to confirm air quality before the premises are handed back
- Waste disposal certificate: all biological waste is transported and disposed of by authorised operators
We work in close liaison with the authorities, insurers and social services as required. All interventions are conducted in complete confidentiality.
Contaminated Zones and Hazardous Environments
Some environments require disinfection due to specific contamination events:
- MRSA or other antibiotic-resistant bacteria outbreaks in healthcare or residential facilities
- Norovirus or gastrointestinal outbreak in schools, hotels, cruise ships or food facilities
- Legionella contamination in water systems, cooling towers, spa facilities
- Chemical contamination: mercury spills, laboratory accidents, drug manufacturing residues
- Vermin infestation aftermath: rodent droppings and urine carry Hantavirus and Leptospira
Each scenario requires a risk assessment, a tailored decontamination protocol and appropriate PPE for our technicians (up to full hazmat suits for the most severe contaminations).
Business and Commercial Disinfection
Beyond emergency situations, regular professional disinfection is increasingly demanded by businesses as part of their health and safety obligations and quality management systems. SOS Nettoyage offers:
- Periodic deep disinfection of offices, meeting rooms and high-touch surfaces
- Restaurant and food service disinfection: HACCP-compliant protocols, documentation provided
- School and childcare disinfection: products safe for children, applied outside occupancy hours
- Hotel and hospitality disinfection: discreet, rapid, room-by-room treatments
- Sports facilities and gyms: treatment of changing rooms, wet areas, equipment surfaces
- Public transport and fleet vehicles: buses, trains, taxis, company vehicle fleets
Disinfection Methods
Chemical Nebulisation (Fogging)
Nebulisation (thermal or cold fogging) disperses a biocidal solution as ultra-fine droplets (1–30 microns) that penetrate into every corner, crack and surface of a room — areas that manual spraying cannot reach. This technique is highly effective for:
- Large volume spaces (warehouses, production halls, auditoriums)
- Complex environments with many surfaces, shelves and equipment
- Post-viral decontamination (influenza, COVID-19, norovirus)
- Mould elimination in humid environments
The room must be vacated during treatment and for a specified airing period afterwards. We provide a re-entry time and ventilation protocol for every nebulisation treatment.
UV-C Light Disinfection
UV-C radiation (wavelength 200–280 nm) destroys the DNA and RNA of microorganisms, preventing them from reproducing. This is a chemical-free, residue-free disinfection method. Our mobile UV-C robots and lamp systems are deployed for:
- Healthcare environments where chemical exposure must be minimised
- Pharmaceutical and food production areas
- Occupied buildings where residual chemicals are undesirable
- Supplementary treatment alongside chemical disinfection for maximum efficacy
UV-C is effective on surfaces in direct line-of-sight; it cannot penetrate behind objects or into shaded areas, which is why it is always combined with contact disinfection for comprehensive coverage.
Contact Chemical Disinfection
Manual contact disinfection remains the cornerstone of any disinfection protocol. It involves the systematic application of validated disinfectants to all surfaces using cloths, mops or spray bottles, with defined contact times. Key products used by SOS Nettoyage:
- Quaternary ammonium compounds (QAC): broad-spectrum bactericidal, virucidal, fungicidal
- Hydrogen peroxide (H₂O₂): powerful oxidising agent, effective against spores; leaves no toxic residue
- Hypochlorite solutions: highly effective against a wide spectrum of pathogens including Clostridium difficile spores
- Aldehyde-based products: for high-level disinfection of medical equipment surfaces

Frequently Asked Questions about Professional Disinfection
What is the difference between cleaning and disinfection?
Cleaning refers to the physical removal of visible soiling (dust, grease, organic matter) from surfaces. It reduces microbial load but does not guarantee the elimination of pathogens. Disinfection uses validated biocidal agents to reduce the concentration of microorganisms (bacteria, viruses, fungi) on surfaces to a level that is no longer harmful. In healthcare and food environments, cleaning must always precede disinfection, as organic matter interferes with the action of disinfectants. For the highest-risk areas, sterilisation (complete elimination of all microorganisms including spores) may be required. SOS Nettoyage applies the appropriate level to each context.
How long must premises be vacated after nebulisation?
The re-entry time after nebulisation depends on the disinfectant used, the concentration applied and the volume of the space. For most cold fogging treatments with QAC-based solutions, re-entry is possible after 1 to 3 hours of ventilation. For thermal fogging with higher-concentration products, re-entry may require 4–8 hours. SOS Nettoyage provides a precise re-entry protocol for every treatment, specifying the ventilation required and whether any surfaces need wiping down before use. We never recommend re-entry before the specified time has elapsed.
Do you provide a disinfection certificate?
Yes. SOS Nettoyage systematically issues a disinfection intervention report for every treatment. This document specifies: the date and duration of the intervention, the areas treated, the products used (with batch numbers), their concentration, the contact time applied and the name of the certified operator. For medical facilities and food businesses, we can also provide the technical data sheets and biocide registration numbers for all products used. These documents are essential for regulatory audits, insurance purposes and HACCP records.
Can you treat Legionella contamination in water systems?
Legionella proliferates in water systems maintained between 25°C and 45°C — hot water tanks, cooling towers, spa installations and dead-leg pipework. Our Legionella control service includes: sampling and laboratory analysis to confirm contamination, thermal shock disinfection (raising water temperature to ≥70°C throughout the system), chemical shock disinfection with chlorine-based or hydrogen peroxide products, and hyperchlorination. Following treatment, we carry out verification sampling to confirm return to compliant Legionella levels. We work in accordance with the Swiss Federal Office of Public Health (FOPH) guidelines for Legionella control.
