Is black mold causing my husband's symptoms and how to clean?« Back to Previous Page

The damp patch and black mold in your closet are very likely contributing to your husband's symptoms. In Dubai's high humidity, this is a common issue, especially on exterior walls where condensation forms. The persistent stuffy nose and headache are classic signs of mold exposure, as spores irritate the respiratory system.

For a small patch (less than one square meter), you can clean it yourself. Wear an N95 mask and gloves. Scrub the area with a mixture of detergent and water, then thoroughly dry it. Do not use bleach, as it doesn't prevent regrowth and can damage porous surfaces. The key is to eliminate the moisture source; use a dehumidifier or run your AC continuously to keep humidity below 60%, as per Dubai Municipality guidelines for indoor air quality.

However, since the wall feels persistently damp, this suggests a larger condensation problem or a potential leak within the wall cavity. Surface cleaning may not address the root cause, and mold will return. For a recurring issue or if the area is larger, a professional inspection is strongly recommended to identify the hidden moisture source and assess the full extent. They can perform lab tests to identify the mold species, which is important for determining the appropriate remediation strategy, especially when health symptoms are present.
