Wall mould is not just an aesthetic issue and an eyesore; it can indicate larger problems in your home’s structure and air quality. If left unchecked, it can also pose serious health risks to you and your family especially if any of your family members have underlying health conditions such as sensitive skin, asthma, sinus, etc.In this in-depth blog post, we will dive into the causes of wall mould, the health risks associated with it, and how you can prevent and remove it effectively.<h3>What is Wall Mould?</h3>Wall mould is a type of fungus that grows on surfaces in moist or damp environments. It typically appears as black, green, or brown patches on walls, ceilings, or other exposed surfaces in areas with high humidity. Mould thrives in places where moisture levels are consistently high, such as bathrooms, kitchens, basements, or areas affected by leaks. While mould is a natural part of the environment and plays a role in breaking down organic matter outdoors, inside your home, it can cause significant issues.Mould can multiply quickly and should not be ignored as early detection and remedy can save you more headache down the road.<h3>Causes of Wall Mould</h3>Mould growth on walls occurs when specific conditions are met: moisture, warmth, and a surface that supports mould growth. Understanding the causes behind mould can help you prevent it in the future.1. Excess Moisture and HumidityThe primary cause of mould growth on walls is excess moisture. This could come from several sources:Leaks: Ceiling leaks, broken pipes, or leaking windows can allow water to seep into your walls. If the moisture is not addressed quickly, mould will begin to grow. Condensation: In poorly ventilated areas, the warm air inside your home can meet the cold surfaces of walls or windows, causing condensation to form. Over time, this moisture can lead to mould growth. Flooding or Water Damage: After a flood or water damage event, your walls may absorb a large amount of water, which creates an ideal environment for mould growth if not addressed immediately.2. Poor VentilationHomes with poor ventilation are more prone to mould growth. Without proper air circulation, moisture in the air has nowhere to go, and it condenses on surfaces. This is especially common in kitchens, bathrooms, and along air-con trunkings, where high humidity is common due to cooking, showering, or laundry.3. High HumidityHumidity levels above 60% are ideal for mould growth. In Singapore where the climate is naturally humid and the average humidity levels range from 70% - 90%, you can imagine our living environment is an inherent breeding hot spot for mould. During the rainy seasons, the risk for mould formation is all the more elevated.4. Water Damage from External SourcesFor those living in landed property, external factors such as heavy rainfall or nearby landscaping that directs water towards your foundation can lead to water seepage into your walls. Cracks in the foundation, gaps in window seals, or improper drainage can further allow water to enter your home and cause damp conditions that foster mould growth.5. Temperature FluctuationsMould thrives in warm, damp conditions. Fluctuating temperatures inside the home, especially during seasonal changes, can contribute to the development of condensation, which creates an environment perfect for mould growth.6. Old or Poorly Maintained PaintIf the paint on your walls has been damaged or is old, it may not be providing a proper barrier to moisture. Cracked or peeling paint can allow moisture to seep through and accumulate on the wall, which can lead to mould.<h3>Health Risks of Wall Mould</h3>While wall mould may on the surface appear to be just an aesthetic problem, it can be harmful to your health. Mould produces allergens, irritants, and mycotoxins that can cause a wide range of health issues and trigger sinus symptoms, skin allergies or in serious cases, an asthma attack. The severity of these risks can vary depending on the type of mould, the duration of exposure, and individual sensitivities.1. Allergic ReactionsMould is a known allergen and those with mould allergies are especially vulnerable to the health effects of mould exposure. Symptoms of mould allergies can include:Sneezing Coughing Runny or stuffy nose Itchy or watery eyes Sore throat Skin rashes In more severe cases, mould allergies can trigger asthma attacks or worsen existing respiratory conditions.2. Respiratory IssuesMould releases spores into the air, which can be inhaled when disturbed. These spores can irritate the respiratory system and lead to more serious respiratory problems. For individuals with asthma, mould exposure can lead to exacerbated symptoms, including shortness of breath, wheezing, and chest tightness. Prolonged exposure to mould spores can also contribute to chronic respiratory conditions and worsen existing lung diseases.People with compromised immune systems such as those with auto-immune diseases, elderly or individuals undergoing cancer treatments are at higher risk of developing respiratory conditions due to mould exposure. Even a small amount of mould can trigger significant health issues in such individuals.3. Mycotoxins and ToxicitySome types of mould produce mycotoxins, toxic chemicals that can pose a serious health risk when inhaled or ingested. These toxins can lead to symptoms such as:Headaches Fatigue Dizziness Memory loss Difficulty concentrating Nasal and throat irritation Prolonged exposure to mould mycotoxins can contribute to more severe health issues, including neurological symptoms, damage to the liver and kidneys, and even cancer in extreme cases.4. InfectionsMould can lead to fungal infections, especially in people with weakened immune systems. Fungal infections can develop in the lungs, sinuses, or skin and may require medical treatment to resolve.<h3>How to Prevent Mould Growth</h3>While it is difficult to completely eliminate the risk of mould in Singapore’s climate, there are several proactive steps you can take to reduce the chances of mould growth on your walls.Prevention is key when it comes to wall mould. The best way to avoid the hassle and health risks of mould is to ensure that your home is moisture-free and properly ventilated. Here are several steps you can take to reduce the likelihood of mould growth:1. Fix Leaks and Water Damage ImmediatelyLeaks from pipes, roofs, or windows can lead to damp spots on walls, providing a perfect environment for mould. The moment you notice a water leak, whether it’s from a pipe, roof, or window, fix it immediately. Even small leaks can lead to significant mould problems if not addressed promptly. Check your roof and plumbing systems regularly to avoid costly repairs down the road.2. Improve VentilationDue to the hot weather in Singapore, many homes have the air-conditioner for long hours each day with doors and windows closed which results in poor ventilation.Proper ventilation is key to reducing moisture buildup in the home. Ensure that all rooms, especially bathrooms and kitchens, are well-ventilated. This can be achieved by installing exhaust fans in the bathroom or corner fans in the kitchen, opening living and bedroom windows to allow fresh air to circulate, and using ceiling fans to promote airflow. In areas with poor natural ventilation, consider using an air exchange system or mechanical ventilation.3. Seal Gaps and CracksSeal any gaps or cracks in your walls, windows, and foundation. This will help prevent external water from entering your home and reduce the possibility of moisture seeping into your walls.4. Keep Your Home DryAlways address standing water immediately. Whether it’s from a spill, a leaky appliance, or a flood, it’s important to dry surfaces as quickly as possible. If any water damage occurs, make sure to use fans or dryers to dry out the affected area before it has a chance to cause mould growth.5. Regularly Inspect Your Walls, Ceilings, Piping &amp; Trunking&nbsp;Perform regular checks of your walls, ceilings, piping and air-con trunking for any signs of moisture or mould growth. If you notice damp spots, water stains, or a musty smell, address it before it turns into a more serious problem.6. Clean and Maintain Your Air Conditioning SystemAir conditioning systems can contribute to high humidity if they are not properly maintained. Clean the filters and ducts of your air conditioning unit regularly to ensure efficient operation. Consider installing a high-efficiency particulate air (HEPA) filter to capture mould spores and other airborne pollutants.7. Regular CleaningRegular cleaning is crucial for removing dust, dirt, and moisture that can accumulate and encourage mould growth. Focus on areas that are prone to dampness, such as bathroom corners, around windows, and behind furniture. Use a mild detergent and water to clean surfaces and dry them thoroughly afterward.<h3>How to Remove Mould on Walls</h3>If you already have mould on your walls, it’s important to take action quickly to remove it before it multiplies. Depending on the extent and severity of the mould, you may be able to clean it yourself, or you may need professional help.1. For Minor Mould ProblemsVinegar: White vinegar is a natural disinfectant and can be used to kill mould on non-porous surfaces. Spray the affected area with vinegar, let it sit for an hour, and then scrub it off. Baking Soda: Baking soda mixed with water can also be used to scrub off mould. It’s a mild abrasive that helps to lift the mould from the surface. Hydrogen Peroxide: For more stubborn mould, hydrogen peroxide (3% solution) can be sprayed onto the affected area and left to sit for 10-15 minutes before scrubbing. Before you commence your self-cleaning, it is important to wear protective gear such as gloves, a mask, and goggles to avoid contact with mould spores as well as the chemicals from the cleaning solution. Make sure the room is well-ventilated by opening windows or using fans during the cleaning and for 24 hours after to ensure full drying.2. For Larger Mould ProblemsIf the mould is extensive widespread, it’s recommended to consult with a professional mould remediation service. Professionals have the tools and expertise to safely remove mould and ensure that it doesn’t return.The mould treatment process is a 3-step process involving:Wipe-down: A full wipe-down using specialised treatment solution which is then left on to penetrate into the walls.Roller Application of Treatment Solution: Treatment solution is carefully applied using roller to all exposed wall surfaces to ensure full penetration and coverage of every single spot of walls and ceiling to kill off all mould spores.Machine Sanding: Machine sanding of walls to eliminate mould carcasses. 3. Repainting Walls After Mould RemovalOnce you’ve removed the mould, it’s a good idea to repaint the walls. Use a mould-resistant primer /sealant and paint coatings to prevent future mould growth. These products contain antimicrobial agents that inhibit mould and mildew.<h3>Conclusion</h3>Mould growth on walls is a common problem in Singapore due to the country’s high humidity and frequent rainfall. It poses significant risks to both health and property, and if not addressed promptly, can lead to serious issues. Prevention is key, and by controlling humidity, improving ventilation, and repairing leaks promptly, homeowners can significantly reduce the risk of mould growth.For existing mould problems, it’s crucial to act quickly, using effective cleaning methods and, when necessary, consulting professionals for extensive remediation.
