AC Leak Causing Black Mold in Dubai - Professional Cost?« Back to Previous Page

The AC in my Dubai Marina apartment has been leaking a bit for a couple of months, and now I’ve spotted this ugly black speckled patch growing on the wall behind the unit. With the humidity lately, it seems to be getting bigger. I’m worried about the health risks for my family and the damage to the wall. What’s the realistic cost range for a professional to properly remove this and fix the leak, and is it a complete DIY no-go?

That black speckled patch is almost certainly mould, and the persistent AC leak in Dubai's high humidity is the perfect environment for it to thrive. It is a complete DIY no-go for two reasons: you need to fix the underlying condensation leak at its source within the AC unit, and disturbing mould without proper containment can spread spores throughout your apartment, significantly increasing exposure.

For professional remediation and repair, costs are highly variable but typically start from AED 1,500. The final price depends entirely on the extent of the mould growth (a small patch vs. inside the wall cavity) and the complexity of the AC leak repair. A proper fix involves isolating the area, using HEPA filtration to capture spores, safely removing the contaminated material, treating the area with antimicrobial solutions, and then addressing the root cause—the leak in the drain pan, condensate line, or insulation.

Always request a detailed inspection and quote that separates the mould remediation cost from the AC repair cost. Reputable providers in Dubai should be able to explain the process and may offer lab analysis to confirm the mould type, which is a sign of a science-driven approach. For any visible growth larger than a square foot, or if any household members are experiencing persistent allergies or respiratory issues, a professional assessment is strongly recommended to safeguard your property and health.
