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.
