Vegas Lung? How Stucco Homes Breed Hidden Mold.
By Franklin Everett ShawIs your stucco home in Las Vegas, Phoenix, or Los Angeles making you sick? It might be mold lurking behind that seemingly impenetrable exterior. “Vegas Lung,” a colloquial term for respiratory illnesses exacerbated by the desert environment, can be significantly worsened by hidden mold growth. This guide will equip you with the knowledge to identify, test for, and remediate mold behind stucco, protecting your health and your home.
Stucco, while durable, isn’t waterproof. Cracks, improper sealing around windows and doors, and even just the porous nature of the material itself can allow moisture to penetrate. This creates a perfect breeding ground for mold, especially in the warm, dry climate where temperature fluctuations can cause condensation within the wall cavity.
First, look for telltale signs. Water stains on interior walls, particularly near windows or where the roof meets the wall, are a major red flag. A musty odor, even a faint one, is another indicator, especially if it’s more noticeable after rain or when the air conditioning is running. Peeling paint or wallpaper bubbling on interior walls can also signal moisture intrusion and potential mold growth behind the stucco.
DIY mold testing kits are readily available at most hardware stores in Nevada, Arizona, and California. These kits typically involve collecting a surface sample with a swab or tape and sending it to a lab for analysis. While these kits can confirm the presence of mold, they often don’t identify the type of mold or the extent of the problem behind the stucco.
For a more comprehensive assessment, consider a professional mold inspection. A qualified inspector will use specialized equipment, such as moisture meters and thermal imaging cameras, to detect hidden moisture and potential mold growth behind the stucco without destructive testing. They can also take air samples to identify the specific types of mold present and their concentration in the air. This is crucial for determining the potential health risks and the appropriate remediation strategy. In Las Vegas, look for inspectors certified by organizations like the IICRC (Institute of Inspection, Cleaning and Restoration Certification) or the ACAC (American Council for Accredited Certification).
If you discover a small area of mold growth (less than 10 square feet) and you’re comfortable tackling it yourself, follow these safety precautions. Wear personal protective equipment (PPE), including a respirator mask rated N-95 or higher, gloves, and eye protection. Contain the area by sealing off the room with plastic sheeting and tape to prevent mold spores from spreading to other parts of the house.
Clean the affected area with a mold-killing solution. A mixture of bleach and water (1 part bleach to 10 parts water) is a common option, but be aware that bleach can damage some surfaces. Alternatively, you can use a commercially available mold cleaner specifically designed for stucco. Apply the solution to the moldy surface and scrub thoroughly with a brush. Allow the solution to sit for the recommended time (usually 10-15 minutes) before wiping it clean with a damp cloth.
Thoroughly dry the area after cleaning. Use fans or a dehumidifier to remove any remaining moisture. This is crucial to prevent the mold from returning. Dispose of all cleaning materials, including the brush, cloth, and PPE, in a sealed plastic bag.
For larger areas of mold growth or if you’re uncomfortable handling mold yourself, hire a professional mold remediation company. These companies have the expertise and equipment to safely and effectively remove mold and address the underlying moisture problem. They will also follow strict protocols to prevent cross-contamination and ensure that the mold doesn’t return. In Phoenix, Arizona, ensure the remediation company is licensed and insured.
Preventing mold growth is key to protecting your health and your home. Address any water leaks promptly. Repair cracks in the stucco and ensure that windows and doors are properly sealed. Improve ventilation in your home by opening windows regularly, especially after showering or cooking. Use exhaust fans in bathrooms and kitchens to remove moisture.
Consider installing a whole-house dehumidifier, especially if you live in a humid area of Southern California or experience frequent condensation. Maintain your air conditioning system to ensure it’s working efficiently and removing moisture from the air. Regularly inspect your stucco for signs of damage or moisture intrusion.
Pay special attention to areas around irrigation systems. Over-watering lawns and gardens can saturate the soil around the foundation, leading to moisture wicking into the stucco. Adjust your watering schedule to avoid over-watering and ensure that sprinklers are not spraying directly onto the stucco.
Consider applying a breathable sealant to your stucco. This will help to prevent moisture from penetrating the stucco while still allowing it to breathe. Consult with a stucco professional to determine the best sealant for your specific climate and stucco type.
Mold behind stucco is a serious problem that can have significant health consequences, especially for residents of arid climates prone to respiratory issues. By understanding the signs of mold growth, testing for mold, and taking appropriate remediation and prevention measures, you can protect your health and your home from the dangers of hidden mold. Don’t let “Vegas Lung” or similar ailments take hold – take proactive steps to ensure a healthy indoor environment. Remember, early detection and prompt action are crucial for preventing mold from becoming a major problem.
