Air Sampling and Spore Count Testing involves collecting indoor and outdoor air samples to determine the types and concentrations of mould spores present. Technicians use specialized pumps or cassettes that draw air over a collection medium, which is then sent to a laboratory for microscopic analysis. The lab typically identifies common mould genera—such as Aspergillus, Penicillium, and Cladosporium—as well as less frequent but more concerning species like Stachybotrys chartarum (often dubbed “black mould”).
This service is particularly vital in humid Australian regions, where high indoor humidity can promote rapid mould growth if not properly managed. By comparing the concentration and type of spores found indoors to those detected outside, assessors can pinpoint whether the property’s indoor spore levels are abnormally high. If the indoor spore count is significantly elevated, it often indicates ongoing moisture issues, such as leaks, poor ventilation, or inadequate air conditioning maintenance.
