DIY mold removal or call a pro for AC leak in Dubai?« Back to Previous Page

Alright, so you're dealing with a classic Dubai issue. That black spotting behind the wardrobe is almost certainly mold, fueled by the AC condensate leak and our high ambient humidity. Here’s the technical breakdown.

First, using supermarket bleach is a major mistake we see all the time. It’s mostly water (which feeds mold) and only bleaches the surface pigment. The root structure (hyphae) remains deep within the gypsum board, and the spores will return quickly. It also creates dangerous volatile organic compounds (VOCs).

The wall itself is the critical factor. Drywall (plasterboard) is porous. If the moisture from the leak has wicked into it, the mold contamination is internal. You can't remediate that by surface cleaning; the affected section needs to be properly removed and replaced. This is a key principle per international IICRC S520 standards, which we adhere to here in the UAE.

For a proper fix, you need to stop the source (repair the AC leak), then address the mold. For a small, contained area, a professional job might involve containment, HEPA vacuuming, antimicrobial application, and removal of the compromised wall section. You're likely looking at a cost starting from AED 1,500 upwards for a proper assessment and remediation, depending on the extent of the damage behind there.

Given it's already spreading, a DIY approach risks cross-contamination and health issues. My strong recommendation is to get a professional inspection to assess the penetration depth.
