Note from your 

Licensed Professional

We are a Certified Covid-19 Remediation Contractor and nationally licensed Air Quality Specialist and have been treating Coronavirus contamination for over 41 years.  We use only the highest quality, non-toxic materials.  Hence, we are not the cheapest contractor you will find.   Be wary of companies who have recently begun virus clean up services or use cheaper or unconventional methods that are not EPA/CDC approved  such as UV light, Vaporized Biocides, Ozone, Hydroxyl Generators, Heat treatment, etc.  Using an inexperienced contractor or a company that cuts corners can be fatal for your staff and customers and subject you to serious personal or corporate legal liability.   There are already cases of serious illnesses resulting from un-licensed companies using toxic materials or improper applications.  Ask your contractor for proof of certification as a decontamination specialist, air quality specialist or toxic material remediator.  We are available to answer any questions about our services or Covid-19 virus.




Advanced Environmental Services is a veteran owned, full-service environmental company specializing in decontamination of private, institutional and government facilities.  Since 2016, we have been awarded over $6 million in government contracts including VA hospitals, FAA facilities, FBI, and dozens of state contracts.  


Below are some basics for our virus decontamination processes.


For unoccupied buildings and equipment:


Broad spectrum, hospital-grade, green/chemical-free virucide/germicide.

  • Delivery method:  ULV fogging

  • Effective contact:  1 second

  • Extended effectiveness: up to  4-6 days

For occupied buildings:


Proprietary blend of ingredients:  Alcohol base with concentrated peppermint.   Blend is infused with tea tree oil to prevent evaporation and guarantee a long-lasting effect (up to 6 days depending on conditions such as heat, humidity, etc.)


All high-risk areas (door knobs, communal areas, bathroom fixtures, etc.) are manually cleaned.


  • Delivery method:  ULV fogging and hypoallergenic cloth

  • Effective Contact:  30 seconds

  • Extended effectiveness:  up to 4-6 days


For both occupied and unoccupied buildings, we treat all HVAC systems with and EPA registered air-quality formula to ensure elimination of airborne pathogens.

Setting Up For Decontamination

Before beginning decontamination procedures, three separate zones are established to reduce the risk of spreading infection.

The first zone, or Exclusion Zone, is generally established within the direct and adjacent areas that the infected person or people have been or may have been. These areas are the focus of the surface and airborne contaminant decontamination, and their size and location vary with each project. In the exclusion zone you can expect the following:

  • Air scrubbing using industrial-grade HEPA filtration

  • Containment barriers to deter the migration of the virus while cleaning and disinfecting protocols are implemented

  • All workers in Personal Protective Equipment (PPE), including Powered Air Purifying Respirators(PAPR) for additional respiratory protection, gloves, protective clothing, etc. No persons except for the decontamination team and personnel authorized by us and wearing the appropriate PPE will be permitted in this area until procedures are complete.

  • Pre-cleaning before disinfectant application, as needed and per the product label

  • The application of EPA registered disinfectants with an emerging pathogen claim from their List N: Disinfectants for Use Against SARS-CoV-2

  • We also highly recommend disinfection of HVAC for this zone

The second zone is the Contamination Reduction Zone (CRZ). This is where we will don and safely doff our PPE and decontaminate ourselves, equipment, tools, and any other items that have been contaminated. The area serves as a buffer between the exclusion zone and support area and is also off-limits to anyone besides approved personnel in the appropriate PPE.

The final area outside the CRZ is our support area. This is a clean area where clean equipment, chemicals, and other items not currently being used are stored. It is also the area from which we will provide administrative support.

How We Disinfect Coronavirus Contamination

Decontaminating the affected areas of a building involves cleaning the air, disinfecting the high risk or high touch areas, and disinfection all other potentially contaminated surfaces. Air cleaning involves placing HEPA filtered air scrubbers inside the building based on the CDC guidelines for Airborne Contaminant Removal. The high risk and high touch areas are cleaned several times starting with door handle upon initial entry, and ending with door handles upon final exit. The decontamination process for surfaces varies with the type of surface, such as porous, non-porous, or semi-porous, and follows the CDC guidelines at a minimum. We utilize a variety of disinfectants from the EPA list N, based on the details of your project. These disinfectants have an approved emerging pathogen claim, which is particularly important for providing decontamination services involving SARS-CoV-2.
