How to remove and prevent wall mold from AC leak?« Back to Previous Page

Based on the symptoms you've described—water leakage from the AC unit, black spots on an external wall, and high indoor humidity with condensation—this is a classic case of mold growth caused by excess moisture, a common issue in Dubai's climate. The persistent humidity and year-round reliance on air conditioning create ideal conditions for mold, especially when a small leak provides a constant water source.

For immediate cleaning of a small, visible patch, a solution of diluted white vinegar (1 part vinegar to 1 part water) can be effective. Apply it to the area, let it sit for an hour, then scrub gently and dry the surface thoroughly. However, this is only a superficial fix. The root cause is the AC leak and the moisture it introduces into your wall cavity. Simply cleaning the surface will not address the mold growing unseen within the wall or the ongoing water intrusion.

The UAE's regulatory framework, particularly the Dubai Green Building Regulations, emphasizes the importance of maintaining indoor air quality and preventing moisture issues that lead to mold. A professional inspection is strongly recommended. Our certified inspectors use tools like thermal imaging cameras and moisture meters to pinpoint the exact source and extent of the leak and the hidden mold growth. Remediation involves stopping the leak at its source, properly drying the affected building materials using industrial-grade equipment, and then sanitizing the area to prevent regrowth.

To prevent recurrence, ensure your AC unit is serviced regularly to prevent condensation leaks and maintain a relative humidity level below 60% inside your apartment, potentially using a dehumidifier.
