Asbestos decontamination


Prior to the 1990s, asbestos was widely used as an insulating material. Since then, studies have shown that prolonged exposure to asbestos fibre can lead to serious health problems like lung cancer (mesothelioma). If you have reason to believe there is asbestos in your home or business, be sure not to touch it The fine particles are practically invisible and travel easily through the surrounding air. Contact Groupe A.D.N.'s experts immediately for a prompt assessment of the situation.

Mold and fungal decontamination

Mold is made up of microscopic organisms (spores) and has a high potential for damaging health. If you see traces of mold, contact Groupe A.D.N.'s fungal decontamination experts without delay.

To tackle fungal contamination or the appearance of fungus or traces of mold caused by water infiltration, Group A.D.N.'s experts begin by setting up a sealed containment zone. They then install HEPA filters to capture all contaminants and particles suspended in the air. Once this is completed, work that generates dust can begin. The next steps involve removing any contaminated materials, doing mechanical brushing and disinfecting affected and adjacent surfaces, always in accordance with procedural standard S520 established by the Institute of Inspection, Cleaning and Restoration Certification (IICRC).

Contrary to popular belief, it is impossible to get rid of mold simply by washing the affected surfaces with bleach or applying a coat of paint. You would only be masking the problem by removing surface traces of mold and would be accelerating the spores' release into the air. This type of work must be entrusted to professionals like Group A.D.N.'s mold experts.

We only use eco-friendly biocides, as required by the industry's highest standards. The mold decontamination protocols we stringently follow comply with the IICRC/MR210's S520 standard. Also, all of our work is guaranteed. If necessary, we can issue a certificate of compliance for the decontaminated air and surfaces. This certificate is produced by an independent external firm recognized by financial institutions, when such a document is required to purchase a property that had been used to grow cannabis or was in extremely unsanitary condition.

Vermiculite decontamination

Mold detection

Mold can form for a number of reasons, including:

  • Flooding;
  • Leaks or water infiltration from the building’s roof, basement or pipes;
  • A too-airtight building, which keeps accumulated humidity from being evacuated;
  • Humidity-causing sources like showers, cooking appliances and other;
  • Cannabis plantation or indoor cultivation.

Mold-related health problems:

According to research conducted by the Public Health Agency of Canada, here are some of the physical symptoms that could indicate the presence of mold:

  • Irritated eyes, nose and/or throat;
  • Breathing problems, coughing, sneezing, runny nose;
  • Fever, nausea, vomiting, chronic fatigue.
