Is dampness and mold causing our persistent coughs?« Back to Previous Page

Based on your symptoms and the visible mold in your Jumeirah Park villa, there is a very high probability that the dampness and mold growth are the direct cause of your family's persistent respiratory issues. The cool feeling you mention is common here, as AC units often overcool to remove humidity, creating cold, damp surfaces where condensation and mold can form, especially in less-ventilated areas like closets.

The black spots in your closet are a clear indicator of elevated relative humidity, likely due to a combination of the UAE's extreme ambient humidity and potential issues like insufficient AC runtime, undersized units, or thermal bridging in the building envelope. Mold spores and microbial volatile organic compounds (MVOCs) released by these colonies are known irritants that cause chronic coughing, nasal congestion, and other allergic reactions.

For a large bedroom, the most effective dehumidification strategy is a multi-pronged approach:
1. Ensure your AC is correctly sized and set to maintain a relative humidity between 40-60%, even if it means raising the temperature setting slightly to prevent over-cooling.
2. Use a dedicated, high-capacity desiccant dehumidifier, as refrigerant-based models struggle in our climate. These are particularly effective for large spaces and can be rented for remediation projects.
3. Improve air circulation with fans and by ensuring furniture isn't pushed directly against walls, especially exterior ones.

However, visible mold signifies an established problem. Surface cleaning alone is insufficient, as the hyphae (root structure) penetrate porous materials. DIY methods often aerosolize spores, worsening exposure. This requires professional assessment and remediation to identify the moisture source, contain the area, and safely remove contaminated materials.

Given the health impacts on your children, I strongly recommend a professional indoor environmental quality inspection. Our certified team can conduct hygrothermal mapping to find the moisture source and provide a definitive remediation plan.
