There is a particular smell mould brings into a home, a damp, heavy smell that tells you something in the house has been holding moisture for too long. Sometimes you notice it immediately. Other times, it starts with a small dark patch on the wall that slowly spreads until one day you realize it is no longer a minor issue.
Mould is more common in homes than many people think, especially in spaces with poor ventilation, leaking pipes, trapped moisture, or areas exposed to constant humidity.
And while many people see it as just a stain on the wall, mould can affect much more than appearance.
Here is what causes it, why it matters, and how to deal with it properly before it spreads further.
What causes mould in homes?
Mould grows in places where moisture stays for too long.
This can happen because of leaking roofs, faulty plumbing, poor ventilation, flooding, damp walls, or even drying clothes indoors regularly without proper airflow.
Bathrooms are common problem areas because of steam and trapped humidity. Kitchens, wardrobes, ceilings, corners behind furniture, and areas around windows are also places mould tends to grow quietly.
Sometimes the issue is not visible immediately. Moisture can stay trapped behind walls, under flooring, or inside ceilings for months before mould begins to show on the surface.
Why mould should not be ignored
The problem with mould is not just the stain.
Over time, mould releases tiny particles into the air. In enclosed spaces, these particles can affect indoor air quality and make the environment uncomfortable, especially for people with allergies, asthma, or respiratory conditions.
Some people may experience symptoms such as:
- Persistent sneezing
- Coughing
- Nasal congestion
- Eye irritation
- Skin irritation
- Difficulty breathing in more severe cases
Children, elderly people, and individuals with weakened immune systems are usually more sensitive to prolonged exposure.
Why repainting over mould does not solve the problem
A lot of people try to cover mould with paint.
It may improve the appearance temporarily, but the mould underneath usually continues growing because the source of moisture was never addressed.
That is why mould often “comes back” after a few weeks or months. The issue was hidden, not removed.
The real solution starts with identifying where the moisture is coming from and treating the affected areas properly.
How to get rid of mould properly
1. Fix the source of moisture
Before cleaning the mould itself, deal with what is causing the dampness.
This may be a leaking pipe, roof seepage, poor ventilation, or trapped humidity in the room. Without fixing this first, mould will likely return.
- Improve airflow
Open windows regularly where possible and avoid trapping moisture indoors for long periods. Air circulation helps reduce the damp conditions mould thrives in.
- Clean affected surfaces carefully
Small mould patches on tiles or non-porous surfaces can sometimes be cleaned using appropriate mould-cleaning solutions.
However, porous materials such as ceilings, fabrics, wood, or upholstery may require deeper treatment because mould can spread beneath the surface.
- Deep clean surrounding areas
Mould particles do not stay in one spot.
They can settle into curtains, sofas, mattresses, carpets, and air vents over time. Proper deep cleaning helps reduce lingering odours, trapped moisture, and contaminated dust within the space.
When should you call professionals?
If the mould keeps returning, covers a large area, has spread into ceilings or furniture, or the smell remains even after cleaning, it is usually a sign that the issue goes beyond surface cleaning.
Professional cleaners are often able to identify hidden moisture areas, clean affected surfaces more thoroughly, and handle deep cleaning with the right equipment and products.
This becomes even more important after flooding, major leaks, or long periods of dampness inside a property.
At Diamond Shine, we help homeowners and businesses handle deep cleaning for spaces affected by moisture, dirt buildup, and environmental contamination.
