The Basics of Mould: What Every Homeowner Should Know

Mould is a common household problem, especially in places with humidity and dampness. Its presence can damage the infrastructure of homes and lead to health issues for its inhabitants. Furthermore, mould can ruin the aesthetics of your interiors and cause unwanted odours. As a homeowner, understanding mould is crucial. This knowledge can empower you to take timely action, ensuring the safety and longevity of your property and preserving the well-being of those who reside within.

In this article, we’ll discuss the basics of mould, such as its types, causes, health risks and prevention methods. Read on.

Types of Mould

Mould can come in various forms, each with its own characteristics and potential health implications. From the notorious black mould to the less alarming white mould, understanding these variations is crucial for effective identification and remediation. 


  • Black Mould: Often linked to respiratory problems, this toxic mould is one of the most dangerous and should be removed promptly. It’s identifiable by its dark hue and can thrive in various spots, from bathrooms to ceilings.


  • Green Mould: Commonly found on walls, textiles and other damp surfaces, it’s generally non-toxic but can trigger allergies. If left unchecked, it can spread rapidly, making its removal harder as time progresses.


  • White Mould: This powdery substance, often mistaken for dust or efflorescence, is usually the beginning stage of a mould problem. While less threatening than its black or green counterparts, its growth signifies increased moisture in the area and warrants a deeper inspection.


Causes of Mould Growth

So what causes mould to grow? Check out these reasons below:


Areas with high humidity levels, such as Victoria, during certain times of the year, can encourage mould growth, especially without proper ventilation. Bathrooms and basements are typical high-humidity areas that require monitoring.


Water intrusion is a mould’s best friend. Whether from roofs, pipes or walls, water leaks, if left unattended, can rapidly spread mould. Periodic maintenance checks can help detect these issues early on.


Cold surfaces, especially during colder months, can create condensation that encourages mould growth. This phenomenon is often seen on metal pipes, windows or concrete floors, causing them to become prime real estate for mould to settle.

Poor Ventilation

A lack of adequate airflow can trap moist air, particularly in older homes. This creates the perfect breeding ground for mould. Modern home designs consider ventilation strategies, but supplementary solutions like exhaust fans might be necessary for many homes.

Health Risks Associated with Mould

Breathing mould spores can trigger respiratory problems, especially in individuals with asthma or allergies. Persistent exposure can exacerbate existing conditions and can even result in persistent coughs, chest tightness and wheezing in those without prior respiratory ailments.

Furthermore, some individuals might experience redness, itchiness or rashes when in contact with mould. These reactions can range from mild annoyances to severe allergic reactions that require medical attention. It’s crucial to note that even indirect contact, such as handling mouldy objects, can cause skin issues.

Mould can also cause watery, red eyes for many individuals. In more aggravated cases, there can be a burning sensation or blurry vision, which urges those affected to seek relief and often avoid certain areas of their homes.

Beyond the immediate physical irritants, prolonged mould exposure can lead to more insidious symptoms like chronic fatigue and recurring headaches. Over time, these symptoms can affect daily life, as they reduce the quality of life and overall well-being.

How to Prevent Mould Growth

Preventing mould growth is essential for maintaining a healthy and safe living environment. By implementing proactive measures, such as regulating humidity, fixing leaks promptly, ensuring proper ventilation and regular cleaning, you can effectively mitigate the risk of mould infestation in your home. Let’s explore these strategies to empower you in the fight against mould intrusion and safeguard your property and well-being.

Regulate Humidity

Dehumidifiers can help maintain an optimal level of humidity. In regions like Victoria, where humidity can fluctuate, keeping a constant check on indoor levels and adjusting appliances accordingly can prove beneficial.

Fix Leaks Promptly 

Regularly inspect your property for potential leaks and address them immediately. Water ingress should be handled expediently to prevent mould establishment, whether from worn-out roofing, damaged plumbing or external flooding.

Ensure Proper Ventilation

This is particularly important for areas like bathrooms, basements and kitchens where moisture can accumulate. Proper ventilation removes moisture and reduces the chances of mould spores settling and proliferating in your home.

Regular Cleaning

Cleaning your house regularly, especially damp areas, is a proactive measure against mould growth. Utilising antifungal cleaners in bathrooms, kitchens and laundry rooms can also provide an added layer of protection against potential mould infestations.
