Mould is one of the most common problems in homes and, at the same time, one of the most difficult to eliminate completely. Many homeowners try quick fixes, such as wiping it away with cleaning products or painting the walls, but the problem returns after a few weeks. If this has happened to you, there is one essential thing to know: mould will not disappear permanently unless you eliminate the cause, not just the effect.
In this complete guide, you will learn how to identify the problem correctly, which methods genuinely work and how to prevent mould from returning over the long term.
What is mould and why does it appear at home?
Mould is a microscopic fungus that develops in conditions of high humidity and moderate temperatures. Mould spores are present in the air and become active when they find a favourable environment.

The most common causes of mould are:
- Excess indoor humidity (above 60%)
- Lack of daily ventilation
- Condensation on windows and walls
- Leaks from outside or from plumbing installations
- Poor thermal insulation
Most often, mould appears in bathrooms, kitchens, bedrooms or poorly ventilated corners.
Why is mould dangerous?
Beyond its unsightly appearance, mould can have serious effects on health. Constant exposure to spores can lead to:
- Eye and skin irritation
- Persistent coughing and breathing difficulties
- Worsening asthma
- Chronic allergies
- Fatigue and headaches
Children, older people and those with respiratory problems are the most vulnerable.
Where does mould most often appear?
To eliminate the problem, you need to know where to look. The most affected areas are:
- Room corners
- Behind furniture
- On exterior walls
- In the bathroom, around the shower or bath
- In the kitchen, near the cooker or sink
Effective methods for removing mould
1. Cleaning with vinegar
White vinegar is one of the most effective natural solutions. It destroys most types of mould.
- Apply undiluted vinegar to the affected area
- Leave it to work for at least one hour
- Wipe with a clean cloth
2. Baking soda
Baking soda helps eliminate odours and prevents mould from returning.
3. Hydrogen peroxide
It is effective on hard surfaces and in small areas.
4. Professional antifungal products
These are recommended in severe cases. They penetrate deeply and destroy spores.
Why does mould return?
Mould returns when you do not eliminate the main cause. Cleaning without prevention is only a temporary solution.
The main causes of recurrence include:
- Constantly high humidity
- Lack of ventilation
- Poor insulation
How to prevent mould
Prevention is the key to a healthy home.
- Ventilate rooms daily
- Use a dehumidifier
- Maintain a constant temperature
- Do not place furniture directly against walls
Long-term solutions
If the problem persists, you need permanent solutions:
- Quality exterior insulation
- Mechanical ventilation
- Repairing leaks
When should you call specialists?
If mould covers large areas or keeps returning, it is recommended that you call professionals.
Conclusion
Mould will not disappear permanently unless you treat its cause. With the right methods and prevention, you can have a healthy, problem-free home.
