Treat black mold near AC in Dubai villa ourselves or call pro?« Back to Previous Page

Do not use bleach. It's ineffective on porous surfaces like drywall and can push toxins into the air, worsening symptoms like the headaches your wife is experiencing.

The location is a major red flag. Mold spreading from a closet corner near an AC unit strongly suggests a condensation issue within the wall cavity, likely from a poorly insulated AC duct or a drain line leak. This is a systemic building issue in Dubai's climate, not just a surface problem. DIY cleaning will only remove the visible tip; the hidden moisture source will guarantee its return.

For a recurring issue of this nature, a professional inspection is necessary. They will use moisture meters and thermal imaging to find the concealed water source—this is the only way to achieve a permanent fix. The remediation cost is driven by the extent of the hidden damage, not the visible patch. It typically involves controlled demolition of the affected wall section, addressing the insulation or leak, and proper antimicrobial treatment.

Before any remediation, insist on an indoor air quality test to identify the mold species. In the UAE, Aspergillus and Cladosporium are common black molds, but only a lab culture can confirm the type and associated health risks. Any reputable company will provide this documented evidence.

Until addressed, improve ventilation in the room and keep the closet doors open. Run a dehumidifier to help lower the ambient moisture level that fuels the growth.
