Is wall mold causing our sinus headaches and cough?« Back to Previous Page

Yes, the black spots and your symptoms are very likely connected to a mold issue caused by the AC leak. In Dubai's high humidity, a constant water leak creates the perfect damp environment for mold to grow inside your walls and under the carpet, often within 24-48 hours. The species commonly found in such scenarios, like Cladosporium or Aspergillus, are known to produce irritants that cause the exact symptoms you describe: persistent sinus headaches, dry coughs, and congestion.

You should treat this as a serious indoor air quality concern. The first step is to stop the source—get an AC technician to fix the leak and drain line immediately. Do not attempt to clean the visible spots with bleach, as this only removes the surface colour and not the root structure, and it can aerosolize the spores.

For a situation that has persisted for months and is causing health effects, a professional inspection is strongly recommended. They can assess the full extent of the hidden moisture damage behind the wall and under the carpet. A proper remediation plan, not just a surface cleaning, is needed to address the colony. In many cases, this involves controlled removal of affected drywall and carpet padding to prevent the spores from spreading further throughout your apartment during cleanup. A company with its own microbiology lab can identify the specific species present, which helps tailor the remediation approach and provides a verifiable baseline to ensure the problem is resolved.
