How to treat black mold on wall for family's health?« Back to Previous Page

That black mould in the corner is a common issue in older Dubai villas, especially on exterior walls where temperature differences between the air-conditioned interior and the hot outside cause condensation. The high humidity we experience for much of the year provides the perfect environment for it to grow.

For your family's health, the coughing is likely a reaction to mould spores in the air. While most residential mould causes allergy-like symptoms (sneezing, congestion, coughing), the specific type can only be confirmed by a lab test. Infants and those with asthma are typically more susceptible.

To treat it yourself safely, first address the moisture source. Ensure your AC is set to a consistent, cool temperature to reduce indoor humidity and prevent condensation on cold walls. Improve air circulation in the room with a fan. For cleaning, wear an N95 mask and gloves. Scrub the area with a solution of white vinegar or a dedicated mould-cleaning agent, then allow it to dry completely. Repaint with a mould-inhibiting primer and paint.

However, since the mould is already affecting your children's health and is on an exterior wall, the visible spots may only be a portion of the growth. It could be spreading behind the wallpaper or within the wall cavity. For a situation like this, a professional inspection is strongly recommended to assess the full extent and identify any hidden moisture problems. They use moisture meters and thermal cameras to find the source, which is critical for a permanent solution. Proper remediation ensures spores are contained during removal, preventing them from spreading throughout your home and worsening the air quality your family breathes.
