Mould Assessment Recommendations - revised

Topics: Contaminants and Hazards, Air, Biological Agents, Indoor Air Location: General, Canada

Excessive dampness and mould growth on building material surfaces and contents can pose health risks and should not be tolerated in indoor environments. A mould assessment determines if mould is present, but does not determine or estimate mould exposure. Health-based exposure limits for indoor mould in residential environments have not been established; inspecting for visible and hidden mould, removing mould where present, and repairing and controlling sources of excessive moisture is the best approach to controlling health risks. Visual inspection is recommended as the primary tool for assessing indoor moisture and mould. Mould sampling is recommended only when the results of a visual inspection are ambiguous or when more detailed information is necessary. Awareness and ongoing prevention activities for mould and moisture are important strategies for building occupants and homeowners.
