Is this mold causing my family's persistent cough?« Back to Previous Page

The black spots you've found are very likely mold, and the persistent cough is a classic symptom of exposure, especially in children. Dubai's high humidity, combined with year-round AC use that can create condensation in hidden spaces, makes older buildings in areas like Al Barsha particularly susceptible to this issue.

For a situation involving health symptoms and visible growth, a professional inspection is strongly recommended over DIY testing. A certified inspector will conduct a thorough assessment to identify all moisture sources and the full extent of the contamination, often using tools like moisture meters and thermal cameras. The most effective method is to combine surface sampling with air quality testing; this determines the spore count in the air you're breathing and identifies the mold species, which is critical for understanding the health risk and planning the correct remediation strategy. A reputable company will have its own microbiology lab to provide this specific analysis.

Remediation must address the cause, not just the visible growth. Professionals will set up containment barriers to prevent spores from spreading to other parts of your home during removal, use HEPA filtration units to scrub the air, and safely remove and dispose of contaminated materials like drywall or insulation. The underlying moisture issue—often a small leak, rising damp, or condensation from the AC—must be identified and repaired, or the mold will return.

Until a professional arrives, avoid disturbing the area, as this can release more spores. Keep the room well-ventilated and consider using a dehumidifier. The Dubai Municipality has guidelines for healthy indoor environments, and reputable remediation providers adhere to standards like those from the IICRC to ensure the job is done completely and safely.
