Can I remove AC mold myself or need pro in Dubai?« Back to Previous Page

The AC in my bedroom has been leaking a bit and now I’ve spotted a patch of black mold, about the size of a dinner plate, spreading on the wall behind the wardrobe. It’s been humid for the last month and I’m worried it’s getting worse, especially with my allergies acting up. Is this something I can handle myself with bleach from the supermarket, or do I absolutely need to call a professional mold removal company here in Dubai, and if so, what’s a realistic cost I should expect for a job this size?

Based on the scenario you've described—a dinner-plate-sized patch of black mold on a wall due to an AC leak—I strongly advise against a DIY removal attempt with supermarket bleach. Here’s why, specific to Dubai's climate.

The high humidity and constant AC use create a perfect environment for mold. The visible patch is only the fruiting body; the root structure (hyphae) is likely embedded deep within the gypsum board. Surface cleaning with bleach will not only fail to eradicate the root system but can also aggravate the situation. Bleach is predominantly water, which can provide additional moisture for the mold to feed on deeper within the wall. Furthermore, disturbing the colony without proper containment and air filtration can cause a significant release of spores, drastically worsening your allergy symptoms and contaminating other areas of your home.

In the UAE, proper mold remediation is a controlled process. It requires isolating the affected area with physical barriers and negative air pressure to prevent cross-contamination, safely removing and disposing of porous materials like contaminated drywall, and using professional-grade biocides and sealing agents to ensure the mold cannot return. Addressing the root cause—the AC leak—is also critical, as per Dubai Municipality regulations which emphasize fixing moisture sources to protect building integrity and occupant health.

For a patch of this size, a professional inspection is essential to determine the full extent. At Saniservice, we would conduct a thorough assessment, including moisture mapping and possibly air quality testing. The cost for a localized remediation job of this nature typically starts from AED 1,500, but this can vary based on the severity and accessibility. Given your health concerns, professional remediation is not just recommended; it is necessary for your safety and the long-term health of your property.
