Our commercial clients include offices, gyms, nursing homes, dentists, veterinary surgeries, nurseries, schools, daycare centres, shops, restaurants and many other businesses.

Complete Sanitisation for your Home

For homeowners concerned they have been in contact with somebody with Covid-19, or have a family member, friend or work colleague that has been ill, fogging and deep cleaning offers reassurance that your home is 99.999% free of bacteria, fungi, and viruses.

Antiviral Deep Cleaning Formula

For an antiviral deep clean we conduct a fogging process in your home or office using a EN 14476:2013 + A2:2019 accredited formula that is certified to kill all Corona Viruses, SARS and Covid-19 within five minutes of contact time. The formula helps reduce virus transmission from human to human and kills the virus on all surfaces. It is also certified to kill many other viruses including Poxviridae - Herpesviridae - Filoviridae (e.g. Ebola, Marburg) - Flavivirus - Hepatitis C Virus (HCV) - Hepatitis Delta Virus (HDV) - Influenza Virus - Paramyxoviridae - Rubella Virus - Measles Virus - Rabies Virus - Coronavirus (e.g. SARS, MERS) - Human Immunodeficiency Virus (HIV) - Human T Cell Leukemia Virus (HTLV) - Hepatitis B virus (HBV).

We also use an eco-friendly product that is safe for use on food contact surfaces. This formula is non-perfumed, non-tainting, biodegradable, phosphate free and safe to use on aluminium.

The Sanitisation Fogging Process

This process involves blasting a fog of fine mist into the air which eliminates all pathogens present. The mist leaves a deposit on all surface areas including areas that are difficult to reach through conventional cleaning. The airborne disenfectant micro droplets are attracted to land underneath, on top of and on the sides of surfaces in the same way that pathogenic microbes do.

The fogging mist can remain in the air long enough to kill airborne viral and bacterial contamination. Walls, ceilings, floors, carpets, soft fabrics and hard surfaces are all subjected to the fogging process, which leaves an anti -viral, anti-bacterial coating on surfaces and kills 99.999% of pathogens within seconds.

  • All touchpoints are wiped clean using a professional viricide solution before the fogging process.
  • We can also clean carpets, and upholstery before the fogging process if required.
  • When fogging has taken place, the location fogged needs to be empty of personnel/animalsl for at least one hour.
  • The effects of this sanitisation can last up to 8 weeks.
  • This decontamination service can also be completed using a biotechnological and environmentally safe solution which offers superior performance and is food safe.

"Studies have shown the application of disinfectants and biocides via aerosol or fogging can significantly reduce the number of pathogens when compared to manual surface cleaning alone."
