Why is Mould Removal Important? 

Moulds are a kind of microscopic fungi that play an important role in nature. Since they feed on organic matter, they help in breaking down various organic elements. 

Reproduction in moulds is through spores that are invisible and float through the air. In the presence of high humidity and the right temperature, they propagate at a fast rate. They can damage furniture and walls, and can even cause structural damage to buildings.

Keep in mind, mould does not cause only cosmetic damage to furniture and clothing. They can have a negative effect on human health too. 

Sensitivity to mould can cause symptoms like a running nose, skin or eye irritation, and wheezing. People who are allergic to mould can experience breathing problems. Patients with lung diseases like asthma or a weak immune system can develop infections from mould exposure.

In most cases, children and older individuals are the ones most affected by mould. Most importantly, for children who are genetically susceptible to asthma, mould exposure can lead to asthma development. However, not all mould species cause allergic reactions.

Some research has pointed out that mould produces microbial volatile organic compounds (mVOCs). These volatile compounds can enter the body through the skin and lungs. These can have more toxic effects on the body than industrial toxins.

Mould exposure can also cause neurotoxicity and immunotoxicity. Constant mould exposure by staying in damp environments can lead to suppression of immune function and cell damage to the neurological system.

In reality, the number of studies on the effects of mould exposure on human health is limited. But there is sufficient evidence that suggests that mould has multiple harmful effects on our health. This makes mould removal an important step for your family’s health.

How to Know if You Have a Mould Problem? 

What makes mould easy to spot is their colour. Mould can be of various colours including black, white, grey-green, or spotted. They can be powdery in nature or can appear in small black clusters. Generally, the material it is growing on shows signs of wrapping or peeling.

Other than the visible signs, you may also notice a musty odour in rooms and places where there is mould growth. This is more likely in places showing long-term effects of water damage. There can also be hidden water leaks behind walls that can lead to mould growth.

In fact, mould is extremely common in public buildings and homes in Australia. Once you have identified the problem, you need to take the right steps to prevent mould growth. The first step involves removing the source of moisture. Then it comes to removing the actual mould.

If you feel that mould has spread more than you can handle on your own, it’s best to get help from a professional mould removal service in Sydney

Choosing the Best Mould Removal in Sydney

Remember, surface cleaning of the mould does not mean that you have remediated the mould underneath. If you are living in a wooden cottage or a remote tiny home with structural limitations, unchecked mould can be a devastating issue.

In many cases, a professional assessment is necessary to determine the source and the exact damage caused by the problem.

Before you pick a mould specialist in Sydney, there are a few points that you need to keep in mind.


It is important to do the right research before choosing a mould removal service. Merely doing a Google search on “Sydney mould removal” is not enough. Start by getting referrals from your friends and neighbours. Check out the testimonials and customer reviews to find out about the quality of service.

Make sure that the company you choose has the necessary expertise and the right technology to get the job done in the best possible manner. Basically, you need a reliable company that will stand behind the service it provides.

Ask the Right Questions

Start by asking the right questions about the health effects caused by mycotoxins released by moulds. That will help you to assess the technical knowledge of the service personnel.. It is also important to confirm if the company provides you with a comprehensive inspection report for the problem along with a plan of action.

Additional questions include inquiring about the cleaning techniques and containment methods. Another important point is to ensure that the company has the necessary certificates and insurance. Generally, an IICRC certification is considered the industry standard. 

At the same time, the company should be able to ensure the full safety of your home and your family members during the removal process. Also, confirm whether you can or cannot stay in your home during the cleaning process.

Define The Scope

It is important to define the scope of work with the company and determine exactly what you are paying for. Apart from mould remediation, the contractor should also be able to remove or correct the moisture problem. Note down the services that are not included in the mould removal process.

Final Thoughts 

These are the best options for professional mould removal in Sydney. As you can see, mould removal is a specialised process that involves an in-depth investigation and certified cleaning techniques. A delay in the process can cause further damage to your living conditions.
