What Is Black Mould?
Black mould, scientifically known as Stachybotrys chartarum, is a type of fungus that thrives in damp, humid environments. It appears as dark green or black patches with a slimy or fuzzy texture and is commonly found in water-damaged buildings, bathrooms, basements, and other areas with poor ventilation.
What Causes Black Mould?
Black mould requires three main conditions to thrive:
· Moisture – From leaks, condensation, flooding, or high humidity.
· Organic Material – Mould feeds on materials like wood, drywall, carpet, and insulation.
· Poor Ventilation – Inadequate airflow leads to high humidity levels, creating an environment for mould growth.
Is Black Mould Dangerous?
Yes, prolonged exposure to black mould can cause health issues, particularly in individuals with allergies, asthma, weakened immune systems, or respiratory conditions. Symptoms of exposure may include:
· Headaches, dizziness, and fatigue
· Irritation of the throat, eyes, and skin
· Persistent coughing or wheezing
· Nasal congestion and sinus infections
· Worsening asthma symptoms
How to Identify Black Mould in Your Home
Black mould appears as dark green or black patches with a slimy or powdery texture. Common areas where it grows include:
· Bathrooms – On shower walls, tiles, grout, and under sinks.
· Kitchens – Around sinks, in cupboards, and near leaky pipes.
· Basements and Crawl Spaces – Due to high humidity and damp conditions.
· Walls and Ceilings – Particularly after water damage or persistent leaks.
· Windows and Air Conditioning Units – Where condensation frequently accumulates.
How to Prevent Black Mould Growth
✔ Improve ventilation by using exhaust fans in bathrooms, kitchens, and laundry rooms.
✔ Use a dehumidifier to maintain indoor humidity levels below 50%.
✔ Fix leaks and moisture issues immediately.
✔ Regularly clean and dry damp areas, particularly in bathrooms and kitchens.
✔ Ensure proper air circulation by keeping furniture and items away from walls.
✔ Use mould-resistant materials, such as treated wood, mould-resistant drywall, and anti-mould paint in high-moisture areas.
How to Safely Remove Black Mould
DIY Mould Removal for Small Areas
If the affected area is less than one square metre, you can attempt to remove the mould yourself. Follow these steps for safe cleaning:
1. Wear protective gear – Use rubber gloves, a P2/N95 mask, and safety goggles.
2. Ventilate the Area – Open windows and doors to increase airflow.
3. Prepare a Cleaning Solution – Mix white vinegar, baking soda, or a commercial mould remover with water.
4. Scrub the Affected Area – Use a sponge or soft brush to clean the mould off hard surfaces.
5. Rinse and Dry Thoroughly – Ensure the cleaned area is completely dry to prevent mould regrowth.
6. Dispose of Contaminated Materials Safely – Use sealed bags to remove any materials that cannot be salvaged.
When to Call a Professional for Black Mould Removal
· If the affected area is larger than one square metre.
· If mould is growing inside walls, air conditioning systems, or hard-to-reach areas.
· If mould reappears frequently, despite cleaning efforts.
· If there are health concerns, especially for people with respiratory issues.
· If the source of moisture causing mould growth is not easily identifiable.
