Is this mold causing our family's health issues?« Back to Previous Page

Based on your description of the black spots, persistent humidity, and the specific health symptoms—especially the duration and timing—it is very likely that mold is a contributing factor. The symptoms you describe, particularly a chronic cough and congestion that worsens at night or upon waking, are commonly associated with prolonged exposure to mold spores in an indoor environment.

In Dubai's climate, the combination of high humidity and constant air conditioning creates a significant risk for mold growth, especially in hidden, poorly ventilated areas like closets, behind furniture, or within wall cavities. The condensation from AC units can provide the moisture mold needs to thrive, even if the rest of the villa feels dry. A five-year-old villa is also at an age where small, undetected leaks from bathrooms or AC drain lines could be contributing to the problem behind the walls.

You should call a professional for an inspection. This is not a situation for DIY assessment. Disturbing the mold by cleaning it yourself can aerosolize a high concentration of spores, potentially making the health issues significantly worse. A proper inspection involves more than just looking at the visible patch; it includes using moisture meters and thermal imaging to find the source of the moisture and air sampling to identify the spore types and concentrations throughout your home. This is critical, as the type of mold (e.g., Cladosporium vs. Aspergillus) can influence the health risk and necessary remediation steps. A professional inspection will provide the evidence needed to understand the full scope of the problem and how to fix it correctly.
