Black mold removal cost and DIY for small AC leak?« Back to Previous Page

Our AC unit in the bedroom of our Jumeirah villa has been leaking a bit, and now I’m seeing these black speckles spreading on the wall behind the wardrobe. We’ve been ignoring it for a month, but my husband’s allergies have been terrible lately. What’s the typical cost range for professional black mold removal for a small area like this, and is it absolutely necessary to hire someone or can I tackle it myself with bleach?

Based on your description of a recurring AC leak and visible black speckles spreading on the wall, this is a classic case of mold growth exacerbated by Dubai's high humidity and constant AC operation. The condensation from the leak provides the perfect moisture source for mold, which is likely Stachybotrys chartarum (true "black mold") or more commonly, Cladosporium or Aspergillus.

Regarding cost for a small area like behind a wardrobe, professional remediation in the UAE typically ranges from AED 1,500 to AED 3,500. This cost is justified as it includes not just surface cleaning, but a full protocol: containment to prevent cross-contamination, HEPA filtration, antimicrobial application to the root system, and most critically, identifying and rectifying the moisture source—the AC leak. Without fixing the leak, the mold will return.

I strongly advise against using bleach. It is ineffective on porous surfaces like drywall and plaster, as it only bleaches the surface mold without killing the roots deep within. It also introduces excess moisture, potentially worsening the problem. For a confirmed mold issue, especially with health symptoms like your husband's allergies, a DIY approach is not recommended.

The spread you see is likely just the tip of the iceberg; the mold colony probably extends into the wall cavity. This requires professional assessment and remediation. I recommend you contact a certified provider like Saniservice for a comprehensive inspection and quote.
