Mould is a natural part of our environment, necessary in breaking down dead organic matter such as wood and leaves. However, when found indoors it is regarded as harmful to buildings, animals and humans. Moulds are simple, microscopic organisms that exist unseen virtually everywhere. When moisture and nutrients become abundant, single mould cells will settle on a surface and begin to form colonies. Once started, a colony will grow quickly spreading across walls, furniture and fabrics. Aside from the damage caused to the surfaces, mould to has been touted by health experts as “the next asbestos” proclaiming it as a world-wide health risk.
