Why Mouldy Ceilings and Walls Develop
Mould growth on walls and ceilings is a common issue that can be both unsightly and damaging to your home. Understanding why this happens and how to address it can help you maintain a healthier living environment.
Mouldy walls are typically the result of excess moisture in your home. This can be caused by a range of factors, including poor ventilation, leaks, or high humidity. When moisture accumulates, it creates an ideal environment for the fungus to thrive. Common places where you might notice growth include corners of walls, behind furniture, and around windows.
If you have a mouldy ceiling, it is often a sign of a leak or condensation issue. Condensation occurs when warm, moist air comes into contact with cooler surfaces, such as a ceiling that isn’t properly insulated. If not addressed promptly, this moisture can lead to mildew growth.
Common Household Activities Contributing to Mould
Everyday activities such as drying clothes indoors and the steam from hot showers can significantly increase indoor humidity. Persistent high humidity in your home creates an ideal environment for the fungus to start forming on your walls. Managing humidity through effective airflow is crucial; however, timing is key. For instance, air conditioners running cold overnight may contribute to its growth as morning temperatures rise, causing condensation on walls when doors are opened to cooler rooms.
How to Identify Mould on Your Walls
Signs of Mould on Walls and Ceilings
Early detection can prevent further damage and health issues. Common signs of mouldy walls and mouldy ceilings include visible discolouration, often appearing as black, green, or grey patches. You might also notice a musty odour, which indicates the presence of mildew, even if it is not immediately visible. In some cases, peeling paint or wallpaper can signal that the fungus is growing beneath the surface.
Advanced Indicators of Mould and Moisture
Severe dampness can manifest as peeling plaster, visible damp patches, or mildew. Walls with a yellow tint, a furry appearance, black speckles, slight discolouration of paint, or small mites are all significant indicators of moisture damage and potential growth.
Symptoms Indicative of Mould Exposure
A musty odour, allergic reactions, or consistent sneezing and sniffles can also signal hidden mildew growth; these are telltale signs of allergies which can be prevented with early inspection and treatment.

How to Remove Mould from Walls and Ceilings Safely
Considerations for Mould Removal
Effective removal depends on its location, the type of wall material, the duration of its presence, and the moisture source. For non-porous walls with small isolated patches, you can use specific solutions that are best at resolving the problem, like Concrobium® Disinfectant or Concrobium® Mould Control, applied with a microfibre cloth.
Handling Porous Materials
For porous surfaces like unpainted drywall, more intensive measures are necessary as the fungus can penetrate deep into the material. Similarly, removing mould from ceilings requires extra care since it often indicates underlying issues like leaks or poor ventilation. In such cases, contacting a professional like Mouldgone is essential for a thorough assessment, advice, and a detailed remediation plan.
How to Effectively Get Rid of Mildew on Walls and Ceilings
Identify the Source of Moisture
The first step in how to get rid of mould on walls and ceilings is identifying and addressing the source of moisture. Mould thrives in damp conditions, so it’s crucial to determine if the moisture is due to leaks, high humidity, or poor ventilation. Check for leaks in roofs, pipes, and windows.
After fixing these issues, begin by removing any existing mould using products like Concrobium® Disinfectant, which is FDA approved, non-toxic, and safe for use around children and pets. For larger or tougher jobs, Concrobium® Mould Control can create an antimicrobial shield to eliminate and prevent future growth.
Both Concrobium products are FDA approved, non-toxic, child and pet friendly and non-staining. If treating the inside of a wardrobe ensure not to re-hang clothes until the entire area is completely dry. Store your hanging items with some space between each item when possible, this ensures air flow is maintained between the clothing and will help to prevent re-growth. It is important to keep the inside of your closet dry to prevent mildew from forming in the first place.
Use Mould-Resistant Products
Once the moisture issue is resolved, you can focus on cleaning the fungus. To remove mould from the ceiling and walls, make sure to select appropriate mould-resistant products to further protect your home. Our Thirsty Camel moisture hangers and pouches are designed to absorb moisture and protect your valuables, including clothes, handbags, and shoes.

Protect your valuables from irreversible damage by strategically placing these long-lasting pouches throughout your home. Regular checks and replacements help maintain a mildew-free environment.
Maintain Proper Ventilation
Adequate airflow helps reduce moisture levels, which is key to avoiding mouldy walls and mouldy ceilings. Ensure that your home is well-ventilated by using exhaust fans in areas prone to humidity, such as bathrooms and kitchens. Open windows regularly to allow fresh air to circulate and reduce indoor humidity. Additionally, consider using a dehumidifier in damp areas to keep moisture levels in check.
