AC leak causing mold: DIY clean or call a pro?« Back to Previous Page

Based on what you've described, this is absolutely not a DIY job and I strongly advise against using bleach. The black spots spreading on the wall indicate an active, moisture-driven colony, and an AC leak is a continuous source of water that will make any cleaning effort futile until the root cause is fixed.

Here in Dubai, our high humidity acts as a catalyst, allowing mold to penetrate porous materials like drywall and concrete. Scrubbing the surface only disturbs it, releasing a massive amount of spores into your home's air, which is a significant health risk. Furthermore, what you see on the surface is often just the "fruit" of the mold; the main root structure (hyphae) is likely growing deep within the wall cavity.

Professionally, this requires a multi-step process. First, the AC leak MUST be repaired by a certified HVAC technician to stop the moisture. Then, a proper mold assessment is needed to determine the extent of the contamination inside the wall. Remediation involves containment of the area with negative air pressure, safe removal of affected porous materials, HEPA vacuuming, and antimicrobial treatment. Using bleach is ineffective as it is mostly water and can actually feed the mold on porous surfaces.

For a villa in Jumeirah, the cost for a proper assessment and remediation is a worthwhile investment in your property's structural integrity and your family's health. Please, get a professional inspection to understand the full scope.
