Should I call a pro for damp wall with black mold?« Back to Previous Page

The damp wall and black spots behind your wardrobe are a clear sign of a moisture issue, which is common in Dubai's climate due to high humidity and year-round AC use. Given that your children are coughing, this warrants immediate and careful attention.

For a small area (under one square meter), you can attempt to clean it yourself, but avoid using bleach. Bleach only removes surface discoloration and does not address the moisture source or the mould roots within porous materials like drywall. Instead, use a dedicated mould remover or a solution of detergent and water, scrub the area, and ensure it is thoroughly dried. However, the dampness indicates an ongoing moisture problem, likely condensation from the AC or a hidden leak, which will cause the mould to return if not fixed.

Because the wall is damp and the area was hidden, the mould growth is likely more extensive than what is visible. With children experiencing respiratory symptoms, a professional inspection is strongly recommended. They can use moisture meters and borescopes to assess the wall's interior for hidden damage and identify the exact moisture source. In many cases, affected drywall or insulation must be removed to properly resolve the issue. A reputable company will provide documented before-and-after testing from an independent lab to verify the space is safe, which is crucial for your family's health.
