How to treat black mold from AC leak in Dubai?« Back to Previous Page

Given the high humidity levels in Dubai, especially during the summer months, the scenario you describe is unfortunately common. The condensation from an AC leak, combined with our humid climate, creates a perfect breeding ground for mold, particularly on porous surfaces like drywall.

The most critical first step is to address the source of the moisture. You must have the AC unit repaired to stop the leak immediately; otherwise, any cleaning efforts will be futile as the mold will simply return.

For a small, isolated patch (less than 1 square meter), you can attempt to clean it yourself using a solution of detergent and water. However, extreme caution is advised. You must wear an N95 mask, gloves, and eye protection. It is vital to note that simply wiping the surface is insufficient. The mold hyphae (root structures) penetrate deep into the porous gypsum board. Surface cleaning will remove the visible colony but leave the infrastructure intact, allowing for rapid regrowth.

In your case, with a "big patch" behind a curtain—a location prone to hidden moisture—the infestation is likely more extensive than it appears. The wall cavity may be affected. Disturbing it without proper containment, such as with HEPA-filtered negative air machines and antimicrobial remediation protocols, risks spreading microscopic spores throughout your villa's living space, leading to cross-contamination and potential health issues.

For a thorough and permanent solution that adheres to Dubai Municipality's health and safety standards, professional assessment and remediation are strongly recommended. Our certified inspectors at Saniservice use thermal imaging and moisture meters to determine the full extent of the damage and execute a controlled remediation process to ensure complete eradication and prevent recurrence.
