WHAT IS MOULD?
The term “mould” refers to a broad group of over 100,000 known microorganisms. Mould, also known in biology as “fungi”, occur naturally in the environment and play a vital role in the global ecosystem. Background levels of mould spores are nearly always present both outside and within buildings and do not pose a health hazard.
Toxic mould is defined as large concentrations of mould within a home or building, far in excess of background levels. Certain species of mould are more toxic than others.
Serious mould growth will not usually occur unless an environment develops within a home that is conducive to growth.
Specifically, mould reproduces when there is an appropriate surface on which to colonize combined with sufficient moisture and heat. Water damage or humidity issues inside a home, often lead to mould growth.
