Mould assessments

Understanding mould contamination

Mould and bacteria pose significant impacts to human health, causing symptoms ranging from allergic reactions, respiratory issues, and, in some cases, mild to life threatening infections. Certain mould species produce mycotoxins, which are toxic to humans.

Other species of moulds and bacteria contain allergens that have the potential of triggering reactions.

Health risks can vary – with contributing factors including:

  • Types and levels of mould or bacteria present
  • Their growth stage,
  • Method of exposure (inhalation, ingestion, skin contact)
  • Individual susceptibility.

Indoor mould growth is strongly correlated to high levels of moisture. Effective remediation strategies requires locating and addressing the source of moisture. Mould can grow almost anywhere, including concealed locations such as wall or ceiling cavities, behind wallpaper, or in subfloor spaces. Even non-visible mould can negatively impact health.
