What is black mould?
Black mould is a type of fungus that grows in damp areas of the home. It often appears as dark patches on walls, ceilings or around windows. Bathrooms, kitchens and basements are common places where it thrives. Mould can grow quickly if conditions remain damp and unventilated.
Why black mould develops in homes
Black mould forms when moisture builds up indoors. This may be caused by leaks, poor ventilation or rising damp. Condensation from cooking, washing or drying clothes inside can also create the right conditions. If moisture is not removed, mould can take hold and spread.
How black mould affects your health
Breathing in mould spores can irritate the lungs, throat and nose. For some people, this causes coughing, wheezing or blocked sinuses. Those with asthma may find their symptoms worsen. Children and the elderly are more at risk because their immune systems are weaker. Long-term exposure may lead to recurring chest infections or skin irritation.

Signs you may have black mould in your home
Black mould may look like small dark spots that grow larger over time. Paint may bubble or peel, and wallpaper can feel damp to the touch. A musty smell is another sign. In some cases, mould may grow out of sight behind walls or under floors, where it can be harder to detect.
Steps to reduce and prevent black mould
Moisture control is the most effective way to prevent mould. Small steps can make a big difference:
- Keep rooms well ventilated by opening windows.
- Use extractor fans in bathrooms and kitchens.
- Dry clothes outdoors if possible.
- Fix leaks in roofs, walls or pipes quickly.
- Wipe away condensation on windows each morning.
