How to permanently stop mold in closet causing kids' cough?« Back to Previous Page

The recurring black spots and your kids' cough are strong indicators of a persistent moisture problem, not just a surface issue. In Dubai's humid climate, especially in areas like Jumeirah Park, this is often caused by a temperature differential between the air-conditioned interior and the hot exterior wall, leading to condensation inside the wall cavity. Bleach only removes surface discoloration but does not address the moisture source or the roots (hyphae) growing within the porous material.

The permanent solution requires a two-step process: first, identify and eliminate the moisture source, and second, properly remediate the contaminated materials. For an exterior-facing wall, the most common fix is to improve insulation to prevent condensation and ensure the wall's vapor barrier is intact. This may require a professional assessment to diagnose the exact point of failure.

After the moisture issue is resolved, the affected drywall or plaster must be properly remediated. Porous materials with deep fungal growth often need to be removed and replaced. Simply wiping will not work. For your children's health, a professional inspection is recommended to identify the mold species and the full extent of the hidden problem, as spores behind walls can affect indoor air quality. A company with a microbiology lab can provide concrete identification and a targeted remediation protocol, not just a superficial cleaning.
