Mould may grow indoors in wet or moist areas lacking adequate ventilation, including walls/ wallpaper, ceilings, bathroom tiles, carpets (especially those with jute backing), insulation material and wood. If moisture accumulates in a building mould growth will often occur. Many different types of mould exist and all have the potential to cause health problems.
Although mould can be found almost anywhere, it needs moisture and nutrients to grow. The key to preventing mould growth is reducing dampness in the home. This can be done by maintaining proper ventilation and reducing humidity.
