Decontamination & Sanitisation Services

Dunbar Services provides expert sanitising, biohazard cleaning and decontamination solutions to protect a wide range of environments, including hospitals, healthcare facilities, government offices, retail and commercial spaces, hospitality venues, private homes, and much more.

Our advanced decontamination and sanitisation methods, such as thermal and mist fogging combined with our natural microbial inhibitor, are designed to reduce surface and airborne contaminants effectively, including bacteria that spread viruses.

We also offer specialised contagion cleaning and certified biohazard cleaning services for high-risk environments requiring heightened infection control and safe handling of hazardous materials, including government facilities, police stations, prisons and shopping centres. All biohazard cleaning is completed using strict safety procedures to safely remove and treat biological hazards.

Our expertise extends to HVAC and air conditioning decontamination, ensuring safe, clean air circulation to support healthier indoor environments. Additionally, we supply personal protection products to help you maintain sanitised spaces and minimise microbial exposure.

At Dunbar Services, we’re dedicated to delivering a safer, healthier environment through rigorous decontamination, sanitisation and biohazard response services. With over 20 years in the industry, our highly trained technicians use proven cleaning and containment methods to eliminate harmful contaminants and reduce the spread of infection. Our team is ready to work with you to create a tailored plan that meets your specific requirements.

Decontamination is the process of removing or neutralising contaminants or infectious bacteria, viruses or fungi that pose a risk to people, animals, and the environment. It plays a critical role in public health, industrial safety, and environmental protection by reducing or eliminating harmful substances from affected surfaces, materials, or spaces. Decontamination is essential in many fields, including healthcare, chemical industries, waste management, and emergency response, particularly in dealing with hazardous materials, infectious agents, or toxic chemicals.

At Dunbar Services, our Decontamination & Sanitisation Services are designed to provide thorough and effective cleaning, disinfection, and sterilisation to ensure safe and contaminant-free environments for our clients.

• Cleaning – Our team begins with an essential and comprehensive cleaning step, physically removing contaminants from surfaces and high-touch areas. This process lays the foundation for effective decontamination, ensuring that any visible dirt or organic material is eliminated, making subsequent treatments even more effective.
• Disinfection – Following cleaning, we apply professional-grade chemical disinfectants that kill or inactivate pathogens on surfaces and equipment. Our disinfection services are tailored to maintain high standards of hygiene and are ideal for environments where a sterile or sanitised setting is critical, such as healthcare facilities, food preparation areas, and offices.
• Sanitisation – For situations that demand the complete eradication of all forms of life and biological agents, we provide advanced sterilisation options. Our techniques include thermal fogging and mist fogging sterilisation techniques. This is perfect for spaces requiring absolute sterility, giving our clients peace of mind that their environment is as safe and secure as possible.

Thermal fogging produces a fine mist of sanitising agents that effectively disperses micro-droplets throughout an area, reaching and settling on all surfaces to eliminate microbial contamination. During this process, the air conditioning system is kept operational, allowing the decontaminant to circulate through the return air, pass through the plant, and then redistribute via the supply air outlets. This approach provides one of the most thorough and rapid methods for sanitising and decontaminating spaces, whether it’s a small living area or a large stadium, ensuring comprehensive coverage and peace of mind.

Mist fogging disperses an ultra-fine mist of antimicrobial solution into occupied spaces, where it settles on exposed surfaces to eliminate microbial contamination. While it may not cover large areas as quickly as thermal fogging, mist fogging is highly effective for general occupied spaces and serves as an excellent supplemental method for ongoing sanitisation or as a follow-up to thermal fogging.

Split system air conditioners can become breeding grounds for microbes. To address this, Dunbar Services thoroughly cleans the air conditioner filter, applies a microbial decontaminant concentrate to the coil, and installs a 15ml SanAir gel, which helps control microbial growth and maintain cleaner air for up to five weeks. With a simple gel replacement every five weeks, microbial levels stay low, reducing the risk of viral infections and enhancing air quality.

HVAC systems are like the lungs of any occupied environment, constantly circulating air and susceptible to microbial contamination. When bacterial counts are high within these systems, they can release contaminants into the air, potentially impacting respiratory health. Viruses like COVID-19 may exploit bacteria within HVAC systems to transition from an inactive state to an infectious form, feeding on mold and riding on dust particles as they travel through the air. By keeping HVAC systems properly decontaminated, we help maintain healthier air circulation, reducing microbial presence and supporting safer indoor environments.

After decontamination, Dunbar Services offers comprehensive solutions to maintain a high level of hygiene and protection, that help to safeguard your environment long-term. Our ongoing protection services include scheduled follow-up treatments, application of antimicrobial coatings, and guidance on best practices to minimise contamination risks.

We use San-Air, an Australian-made, natural microbial inhibitor that reduces bacteria in the air. Safe for people and pets, San-Air helps maintain a clean environment by continuously neutralising contaminants in the air and on surfaces. This added layer of defence actively inhibits the growth of harmful pathogens between cleanings.

We work closely with clients to implement tailored protocols and hygiene routines that reinforce cleanliness, ensuring a consistently safe and sanitary environment. Through these preventative measures, we empower our clients to keep their spaces safer for everyone, well beyond the initial decontamination.
