How to permanently fix AC leak and black mold in JLT?« Back to Previous Page

Your AC leak is the root cause, and in Dubai's high humidity, simply cleaning the visible mold won't stop it from returning. The constant moisture from the leak is creating a recurring food source for mold growth inside your wall cavity.

The most effective approach is a two-step process: fix the leak, then remediate the mold. First, a certified HVAC technician must diagnose and repair the AC drain line or condensation pan issue causing the leak. This is a mechanical fix that stops the water source. For the existing mold growth behind the unit, this is a serious case requiring professional remediation. Disturbing it yourself can aerosolize spores throughout your apartment. Specialists will contain the area, safely remove the contaminated drywall or insulation, and HEPA-vacuum all surfaces.

To prevent recurrence after the repair and remediation, improve ventilation around the unit to reduce condensation and consider using a dehumidifier in the bedroom, especially during the more humid winter months. For verification, a post-remediation test by an independent microbiology lab is the only way to confirm the spore count has returned to a normal level and the issue is truly resolved.
