Mold in wardrobe from AC leak: cost to fix?« Back to Previous Page

We've lived in our Jumeirah villa for 2 years and just noticed a large patch of black mold in the back of the master bedroom wardrobe, which is on the exterior wall. The AC unit is right outside that wall and I'm worried a leak might be the cause. I can smell it strongly when I open the doors. What's the typical ballpark cost for professional mold remediation for a small area like this, and is it a complete DIY no-go?

Based on the symptoms you've described—a large black patch on an exterior wall, a nearby AC unit, and a strong musty odor—this is a classic case of mold growth driven by a moisture source, likely a condensate drain line leak from your AC unit. The humid Dubai climate and year-round AC use create perfect conditions for this issue. The persistent moisture from even a minor leak, combined with organic materials in the wardrobe (e.g., wood, clothing), facilitates rapid mold colonization.

For a case like this, professional remediation is strongly advised, not a DIY project. Disturbing the mold without proper containment and air filtration can aerosolize spores, spreading the contamination to other parts of your villa and posing potential health risks. A certified professional will first identify and rectify the moisture source (the AC leak), then implement engineering controls to isolate the area before safe removal and hygienization of affected materials.

The ballpark cost for a small, contained area like a wardrobe in Dubai can range from AED 1,500 to AED 4,000. This estimate typically includes the inspection, moisture mapping, containment setup, removal of contaminated materials, HEPA vacuuming, antimicrobial treatment, and post-remediation verification to ensure the issue is fully resolved. The final cost depends on the extent of moisture damage behind the wall.

Given the strong smell, indicating significant growth, we recommend an immediate professional assessment.
