Structural Assessment and Mould Surveys (Marijuana Grow Operation)


DBA with qualified staffs have conducted environmental investigations and structural surveys on residential buildings located in Ontario, that were previously used as a marijuana grow site and had gone through major damages due to the occurring fire at the building. 

DBA’s assessments are based on:

  • A visual assessment of readily accessible surfaces in the interior of the building in order to identify areas where suspect mould is most likely to exist.
  • Non- viable air sampling for mould spores including reference samples and blank media.
  • Non-viable and viable bulk sampling for mould spores using tape lifts and swabs.
  • CO, CO2, RH and moisture values
  • AIHA / CALA approved laboratory analysis, etc.
