Understanding Mould

Mould is one type of fungus whose job it is to decompose of dead organic material. Moulds sometimes can infect living plants and animals. The spores and fibre like structure of individual mould colonies are too small to see without a microscope.

What is mould?

When enough mould grows together on a surface it will appear in different colours. The colour of mould is influenced by nutrient source and the age of the colony. It is impossible to determine what type of mould is growing by visual inspection only.

Moulds are naturally occurring organisms playing a major role in the earth’s ecosystem. They are the most important part of nature’s ability to recycle. These microscopic fungi exist everywhere except under water, parts of the Arctic and Antarctic, and in artificial environments like clean rooms.

Fungi have to depend on other organisms or on the forces of nature to carry them to a food source, or to bring food to them. Mould spores and mould fragments are in the air we breathe every day.



What makes moulds grow?

Mould needs water to grow, no water and no growth. Mould also needs food, oxygen and ideally a warm temperature. Since mould decomposes dead organic material it can grow on wood, Mould can also digest some synthetic materials such as adhesives, pastes and paints.

While mould cannot feed off of inorganic material such as concrete, glass and metal, it can however grow on dirt, debris or hairs that are on/in these surfaces. Moulds prefer wet or damp materials but can get their moisture from the air in the form of high humidity, typically above 60% relative humidity.

If mould has the opportunity to grow (add water) it will. The key to reducing the growth of moulds in buildings is to minimize the water. Reduce the ways in which water accumulates in the building structure and mould won’t continue to be a problem.

Mould -spores

How Does Mould Spread?

Mould can grow by extension of tiny root hairs called hyphae. Mould also makes spores that are like very small seeds. When spores are released they can be carried by air or water to new locations.

As mould dries this release is accelerated in an effort to spread the seeds to new areas to grow. Spores are so small that primarily air currents affect them.

If you have visible growth occurring from a water intrusion, do not dry it or the building materials out uncleaned. As the moisture of the mould or building material decreases, the release of spores increases exponentially.



There is a lot of talk about mycotoxins, which can be released by the mould spores when the actual spore itself is dead. We have all heard about them and they continue to be a problem with most methods and products used in Mould Remediation.

Mycotoxins are very real and can be very detrimental to the health of humans. Scientists do not yet know how many mycotoxins may exist, although currently there are approximately 250 that have been detected.

Moulds that have been known to potentially produce these toxins are Acremonium, Alternaria, Aspergillus, Chaetomium, Cladosporium, Fusarium, Penicillium, and Stachybotrys. Even though these moulds may potentially produce mycotoxins, they will not do so unless specific environmental conditions exist.

Our product works differently to others used in the Mould Remediation industry. Because of the hyper-wetting agent in our product, it encourages the shell of the spore to open up. Our product then encases the harmful mycotoxins, before having a chance to become airborne, by attacking them straight away whilst they are vulnerable. Other methods of remediation basically attack only the shells, leaving the contents of the shell (spores containing the harmful mycotoxins) to happily release the mycotoxins into the environment thereby causing the toxic problem.

The above diagram is that of fabric that has been treated with our product. The bacterial spore that is trying to attach itself to the fabric doesn’t stand a chance. Once the bacterial spore makes contact with the treated fabric, it opens up and lets the 2000 in. Although it is not required, you may still incorporate HEPA vacuuming after the treatment of GM2000.

The Mould Doctor to the rescue!

Living in a damp house subject to mould can be bad for your health. The good news? You can do something about your mould problem! Call The Mould Doctor to arrange a FREE quote, which includes an initial inspection, mould testing and a detailed report. 

The Mould Doctor can remove mould from your property, sanitise it and advise you on ways to reduce excess moisture and improve ventilation ensuring your home or business remains a healthy and safe place to live or work.

Mould Removal is required when a mould problem has been identified by a property owner/landlord, a tenant or a builder. The first tell tale sign of the presence of mould is a musty odour. You may even be able to see black mould in poorly ventilated and damp areas. If either of these symptoms occur it is time to call The Mould Doctor to book a Free Mould Inspection.
