For a small patch (under one square foot), a DIY approach might be possible. You must wear an N95 mask, gloves, and eye protection. Scrub the area with a detergent solution, but never use bleach as it can worsen indoor air quality and only bleaches the surface. The underlying wall material is key; if it’s porous like drywall or plaster, the mold roots are likely deep within and the material usually needs replacement.

Given the location (bedroom), the size (likely larger than first visible), and the health symptoms, a professional assessment is strongly recommended. They can determine the full extent of the growth, identify the species, and ensure it is contained during removal to prevent spores from spreading throughout your home. In Dubai, reputable remediation follows strict containment protocols to protect your indoor air quality during the process. They will also identify and address the underlying moisture source, which is critical to prevent it from returning. For your children’s health, verifying the mold is fully removed and the air quality is safe is the priority.
