The document discusses potential reasons for the small mould industry in the UK, including low public awareness of mould problems, the quality of UK buildings, skepticism about health effects, and lack of clear guidelines. It presents survey findings that over a third of UK homes have condensation issues and over a quarter have mould. While guidelines are imperfect, there is broader consensus that mould can cause health problems, significant mould growth should be removed rather than just toxic mould species, and successful remediation criteria exist. The CDC and other organizations state that mould hazards should not be considered differently than other common indoor molds.
