Fungus growth on walls is a common problem in many homes, especially in areas with high humidity or water damage.
Not only is it unsightly, but it can also pose health risks if left untreated. Cleaning fungus from walls is essential to maintain a healthy living environment.
In this article, we’ll walk you through how to effectively remove fungus from your walls and prevent it from returning. We will also address some common questions about fungus on walls.
What Causes Fungus to Grow on Walls?
Fungus, including mould and mildew, thrives in moist, humid environments. It typically grows on walls when there is excess moisture present due to various factors. Some of the most common causes of fungal growth on walls include:
- Leaks or water damage: Water from leaks in pipes, roofs, or windows can seep into walls and create a breeding ground for fungus.
- High humidity: Areas with high levels of humidity, such as bathrooms or basements, provide the ideal environment for fungus to grow.
- Condensation: When warm, moist air comes into contact with cold walls, condensation forms, creating the moisture fungus needs to thrive.
- Poor ventilation: Insufficient airflow in a room can lead to trapped moisture on the walls, encouraging fungal growth.
Understanding the cause of the fungus growth on your walls is crucial in addressing the problem effectively.
How Can I Clean Fungus from Walls?
Removing fungus from walls is relatively straightforward, but it requires proper preparation and cleaning techniques. Here’s a step-by-step guide to help you clean fungus off your walls safely and efficiently.
1. Gather the Necessary Cleaning Supplies
Before you begin cleaning, make sure you have all the necessary tools and cleaning agents:
- Rubber gloves, goggles, and a mask (preferably an N95 mask) to protect yourself from fungal spores.
- A vacuum cleaner with a brush attachment or a microfiber cloth to remove loose dirt and dust.
- Cleaning solutions: vinegar, hydrogen peroxide, or a commercial mould cleaner.
- A bucket of water.
- Soft sponges, scrub brushes, or microfiber cloths for scrubbing the walls.
- A step ladder if the fungus is located at the top of the wall or in hard-to-reach areas.
- A fan or dehumidifier for drying the wall afterward.
2. Protect Yourself and the Area
Fungus can release spores that can irritate the eyes, skin, and respiratory system, so it’s essential to take safety precautions. Wear rubber gloves, goggles, and a mask to protect yourself. Open windows to improve ventilation and reduce the risk of inhaling harmful spores.
Next, clear the area around the affected wall. Move furniture and cover any items that might be in the way with a plastic sheet or tarp to avoid getting them wet or contaminated with spores.
3. Remove Loose Fungus and Dust
Before applying any cleaning solution, it’s important to remove any loose fungus, dust, or dirt from the wall. Use a vacuum cleaner with a brush attachment or a microfiber cloth to gently remove the fungus and any surface dust. Be careful not to disturb the fungus too much, as this could release spores into the air.
4. Apply a Cleaning Solution
There are several effective solutions you can use to clean fungus from walls. Here are a few options:
- White vinegar: White vinegar is a natural fungicide and can kill most types of fungus. Pour undiluted vinegar into a spray bottle and spray it directly onto the affected areas. Allow it to sit for an hour before scrubbing.
- Hydrogen peroxide: Hydrogen peroxide, at a 3% concentration, is another powerful cleaner that can kill fungus. Spray it onto the affected wall and let it sit for 10 minutes before scrubbing.
- Commercial mould cleaner: If the fungus is widespread or particularly stubborn, you may want to use a commercial mould cleaner. These cleaners are specifically formulated to kill fungus and mould and can be found at most home improvement stores.
5. Scrub the Affected Area
After the cleaning solution has had time to sit, use a soft sponge, scrub brush, or microfiber cloth to scrub the wall. Apply gentle pressure and work in small sections to avoid damaging the wall’s surface. Focus on removing all visible fungus, but be careful not to oversaturate the wall with cleaning solution or water, as this could lead to further moisture problems.
For stubborn fungus, you may need to repeat the process. Be sure to check all corners, edges, and crevices where fungus can hide.
6. Rinse and Dry the Wall
Once the fungus has been removed, rinse the wall with clean water to remove any remaining cleaning solution. Then, use a dry microfiber cloth to thoroughly dry the wall. Fungus thrives in moist environments, so it’s essential to dry the area completely to prevent the fungus from returning.
If possible, use a fan or dehumidifier to speed up the drying process. Ensure the area is completely dry before moving any furniture back or using the room again.
How Can I Prevent Fungus from Growing on Walls?
While cleaning fungus from walls is important, preventing it from coming back is crucial. Here are some steps you can take to reduce the likelihood of future fungal growth:
- Fix leaks immediately: If you discover any leaks in your plumbing, roof, or windows, fix them as soon as possible to prevent water from entering the walls.
- Improve ventilation: Increase airflow in areas prone to humidity, such as bathrooms and basements. Install exhaust fans in bathrooms and kitchens to help remove moisture.
- Use a dehumidifier: In areas with high humidity, using a dehumidifier can help maintain a dry environment and prevent fungus from growing.
- Control condensation: To prevent condensation on walls, maintain a consistent indoor temperature and avoid drastic temperature changes.
- Repaint with mould-resistant paint: After cleaning, consider repainting the affected area with mould-resistant paint. This can help prevent future fungal growth.
FAQs: About Fungus on Walls
Is fungus on walls harmful to my health?
Yes, fungus on walls can be harmful to your health. The spores released by mould and mildew can cause allergic reactions, respiratory problems, and aggravate conditions such as asthma. It’s important to clean it promptly and take precautions to prevent future growth.
Can I use bleach to clean fungus from walls?
Bleach is effective in killing surface mould but is not the best option for porous surfaces like drywall. It may also leave behind harmful chemicals and unpleasant odors. For better results, try natural cleaners like vinegar or hydrogen peroxide.

When should I call a professional to remove fungus from my walls?
If the fungus covers a large area, persists despite cleaning, or is caused by significant water damage, it’s best to call a professional. They have the equipment and expertise to safely and effectively remove fungus and prevent it from spreading.
Conclusion
Cleaning fungus from walls is an important step in maintaining a healthy home. By following the proper cleaning steps and addressing the root causes of moisture, you can effectively remove fungus and prevent it from returning.
