DIFFERENT TYPES OF MOULD IN NEW ZEALAND
Updated: Aug 18
More than one-third of all homes in New Zealand have mould issues. This is largely due to humidity and damp or wet conditions. Mould commonly found on surfaces around your home are generally non-toxic. However, when the spores release into the air they can produce allergic symptoms in people who are susceptible.
Individuals with weaker immune systems are at a greater risk of adverse effects brought by mould exposure, such as the elderly, infants, and asthmatic people. The good news is, most people who suffer from ill health due to mould in buildings recover when the mould is professionally removed. So, if you suspect mould in your home book an inspection and have this harmful substance removed as soon as possible.
WHAT TYPE OF MOULD IS IN NEW ZEALAND?
To ensure effective and safe mould removal, we need to determine the exact type of mould
that we’re dealing with before any treatment is carried out. While contained in a sealed environment, most mould isn’t a direct threat to people. However, as soon as mould is visible or the environment is opened, spores may be released.
The most common types of mould that we find inside New Zealand homes and buildings are
Stachybotrys chartarum, Aspergillus/Penicillium, Cladosporium and Fusarium. Commonly known as black mould, Stachybotrys chartarum is highly toxic. That’s why it must only be handled, tested, and removed by a qualified, experienced specialist. It’s often found growing inside wall cavities. It favours very damp conditions and is associated with leaking buildings in New Zealand.
Aspergillus/Penicillium, Cladosporium and Fusarium are other types of hazardous moulds that
are often found growing on walls (and in cavities), insulation, clothing, around windows, on plants, or in soil. Colours range from white, grey, and black to green, yellow, and brown.
The diverse appearance of mould can make it difficult for homeowners to diagnose what they’re dealing with – unless you have the experience, expertise, or access to appropriate testing.
