Urgent to fix AC leak and black mold?« Back to Previous Page

AC leaks in Dubai's climate create a continuous moisture source, making this a situation that requires prompt professional attention. The black patch on the wall indicates active growth, which is being fed by the condensation from the unit. Self-treatment with bleach is not recommended; it only bleaches the surface colour and does not address the root moisture problem or the hyphae (roots) growing within the porous wall material.

Your morning congestion is a common indicator of prolonged exposure to mould spores. Given the ongoing leak and visible growth, an inspection is warranted. A professional assessment will identify the full extent of the contamination, including inside the AC unit and potentially within the wall cavity, and pinpoint the exact species. This is important as some types, like Stachybotrys (often called 'toxic black mould'), require more stringent containment protocols for safe removal.

For a verified resolution, the process must start with fixing the AC leak to eliminate the moisture source. The remediation should then involve physically removing the contaminated porous materials (like the affected section of drywall) under containment to prevent spore dispersal throughout your home. Surface cleaning alone is insufficient. Following remediation, post-clearance testing is the only way to confirm the indoor environment has been returned to a healthy state.
