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

Based on your description of a large, spreading black mold patch from an AC leak in a Jumeirah Park villa, this is a serious issue that requires immediate professional attention. The high humidity and constant AC operation in Dubai create a perfect environment for aggressive mold growth, particularly Stachybotrys, the "black mold" you described, which can release harmful mycotoxins.

DIY remediation with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall, as it only bleaches the surface mold while leaving the root structure intact. It also fails to address the moisture source, guaranteeing the mold will return. More critically, improper handling can aerosolize the spores, spreading the contamination throughout your home and significantly increasing health risks and the eventual remediation cost.

The realistic cost for professional remediation depends on the extent of the spread, which often goes deeper into the wall cavity than is visible. For a significant patch like yours, expect a ballpark range of AED 2,500 to AED 7,000+. This includes containment to prevent cross-contamination, safe removal of affected building materials, HEPA vacuuming, antimicrobial treatment, and addressing the root cause—the AC leak—to prevent recurrence. All work must comply with Dubai Municipality's strict health and safety standards.
