Mould is very common in homes. It can grow on tiles, fabrics, carpets, wood and other materials when moisture is present. Key spots are around window frames, in bathrooms, anywhere condensation forms, and where leaks and rising damp lead to moist patches on ceilings and walls. Two black moulds commonly found in homes are Cladosporium and Alternaria fungi. Another black mould is Stachybotrys chartarum, which can release specific toxins that are harmful to humans.
