Summary

When building materials become damp, fungal spores and bacteria present in indoor air and dust can colonise the building materials and grow, producing visible contamination (mould). Inhalation of mould has been associated with allergic reactions, toxic and irritant effects and infections. Indoor mould growth can be prevented or minimised by actively maintaining, inspecting, and correcting buildings for moisture problems and immediately drying and managing water-damaged materials. However, necessary steps are not always taken and given the potential for adverse human health effects, it is important that mould occurring in the indoor environment be removed and that the cause of the high moisture contents also be addressed. This report considers two bodies of information: Advice, provided by various organisations, on approaches for the removal of mould Evidence for the efficacy of approaches for the removal of mould
