Black mold from AC leak: professional cost or DIY?« Back to Previous Page

Based on the scenario you've described, this is a serious situation that requires professional attention. The black patch behind the wardrobe is a visible sign, but the AC leak and Dubai's high humidity mean the problem is likely more extensive, with potential growth inside the wall cavity and the AC unit itself.

For a patch the size of a dinner plate, a professional remediation cost in Dubai can typically range from AED 1,500 to AED 4,000. This variance depends on the extent of hidden damage, the materials affected (drywall vs. concrete), and whether the AC system itself requires cleaning. A reputable company will provide a firm quote after a thorough inspection, which should include moisture mapping and air quality testing to determine the full scope.

DIY is strongly discouraged. Over-the-counter sprays from ACE are surface-level biocides and will not address the root cause—the moisture from the leak. They can also agitate spores, increasing airborne contamination and health risks. More critically, improper handling can violate tenancy agreements and Dubai Municipality public health regulations, which mandate proper disposal of contaminated materials.

The combination of an active water source and our climate creates a perfect environment for rapid mold proliferation. Attempting a DIY fix often leads to recurrence and higher costs later. A professional team like ours at Saniservice will not only remediate the visible mold but also identify and rectify the moisture source, conduct antimicrobial treatment, and provide a warranty.
