AC mold issue: DIY bleach or call Dubai professional?« Back to Previous Page

Based on your description, this is a classic case of AC-induced mold growth exacerbated by Dubai's high humidity, and I strongly advise against using bleach. The black speckles are likely Stachybotrys chartarum or another toxigenic species, which bleach cannot effectively eliminate on porous surfaces like drywall. Bleach's water content can actually feed the mold roots deeper into the material, causing regrowth.

The leaking AC unit is the primary moisture source, and the confined space behind the wardrobe creates a perfect, stagnant micro-environment for proliferation. Your wife's stuffy nose is a significant indicator of potential health effects from mycotoxin exposure, making professional remediation a necessity, not an option.

In the UAE, proper mold remediation follows IICRC S520 standards. For a situation like this, a professional inspection (costing approximately 500-800 AED) is critical to assess the extent behind the wall. Remediation for a single room typically involves containment, HEPA filtration, removal of contaminated porous materials (the affected section of wall), and antimicrobial treatment of the area. For a small room, expect a range of 2,000 - 5,000 AED depending on the severity.

Given the health symptoms and the hidden nature of the problem, a DIY approach is ineffective and risky. You need to address the AC leak immediately to stop the moisture source and then call a certified professional to handle the contamination.
