Mold (or mould) grows where moisture and organic material meet — often behind drywall, in attics, basements, and around plumbing leaks. Visible mold is a health hazard (especially for asthma/allergies) and a sign of unresolved moisture. Some types (Stachybotrys/'black mold') trigger insurance and lender concerns. Moisture-meter readings are a standard component of a home-inspection report; prior remediation receipts are a standard disclosure item; mold remediation in BC is unregulated trade work — WorkSafeBC occupational-exposure rules under Part 6 of the Occupational Health and Safety Regulation govern worker safety during remediation but do not establish a provincial certification regime for remediators.
