Types of Common Moulds: Black, Green, White.

Mould is a common issue that many homeowners face. It can be unsightly, cause damage to your property, and even lead to health problems. Understanding the different types of mould is essential for effective identification, prevention, and remediation. In this article, we will explore three common types of mould: black mould, green mould, and white mould.


What is Mould?

Mould is a type of fungus that thrives in damp and humid environments. It grows on various surfaces, including walls, ceilings, floors, and even furniture. Mould reproduces by releasing tiny spores into the air, which can then settle and grow on suitable surfaces. It is important to address mould issues promptly to prevent further damage and ensure a healthy living environment.


Different types of mould have distinct appearances and characteristics. Let's explore three common types: black mould, green mould, and white mould.

Black Mould

Black mould, scientifically known as Stachybotrys chartarum, is a notorious type of mould. It typically appears as dark greenish-black patches and has a slimy or wet texture. Black mould prefers materials with high cellulose content, such as drywall, paper, and wood. It often thrives in areas with excessive moisture, such as bathrooms, basements, and areas affected by water leaks or flooding.




Exposure to black mould can cause various health issues, especially when individuals inhale or come into contact with its spores. Symptoms may include respiratory problems, allergies, skin irritation, and even more severe reactions in individuals with compromised immune systems. If you suspect the presence of black mould in your home, it's important to address the issue promptly and seek professional assistance for safe removal.


Green Mould

Green mould, also known as Aspergillus, is a common type of mould that can be found both indoors and outdoors. It appears as greenish patches and has a fuzzy or powdery texture. Green mould can grow on various surfaces, including walls, ceilings, food, and even household plants. It thrives in areas with high moisture levels, such as bathrooms, kitchens, and basements.

Exposure to green mould can cause allergic reactions in some individuals, particularly those with respiratory conditions or allergies. If you notice green mould in your home, it's important to address the underlying moisture issue and remove the mould promptly. Proper ventilation, reducing humidity levels, and fixing any water leaks can help prevent the growth of green mould.


White Mould

White mould, also known as powdery mildew, is a common type of mould that often affects plants, crops, and organic materials. It appears as a white, powdery substance on the surface of leaves, flowers, and fruits. However, white mould can also grow indoors on materials such as wood, paper, and fabric if the conditions are favorable.

While white mould is less harmful to human health compared to black mould, it can still cause respiratory problems and allergic reactions in susceptible individuals. If you notice white mould growth indoors, it's essential to identify and address the source of moisture to prevent further mould development. Proper ventilation, reducing humidity levels, and improving air circulation can help combat white mould issues.


Dealing with Mould

When dealing with mould issues, prevention is key. Here are some preventive measures and steps to take if you encounter mould in your home:

  1. Maintain proper ventilation and airflow in your home.

  2. Keep humidity levels below 50% to discourage mould growth.

  3. Repair any water leaks or plumbing issues promptly.

  4. Use mould-resistant materials in areas prone to moisture, such as bathrooms and basements.

  5. Clean and dry any water-damaged areas within 24-48 hours.

  6. Use mould-killing products or natural remedies like vinegar or hydrogen peroxide to clean mould-infested surfaces.

  7. In severe cases or for extensive mould growth, consult a professional mould remediation specialist.

Remember, mould issues can be complex, and it's essential to address them effectively to ensure a healthy living environment.


Understanding the different types of mould is crucial for homeowners to identify, prevent, and address mould issues effectively. Black mould, green mould, and white mould are three common types that can pose risks to both property and health. Prompt action, including identifying and addressing moisture sources, proper cleaning, and seeking professional help when necessary, is key to dealing with mould effectively.
