Black mold on wall: DIY or call pro in Dubai?« Back to Previous Page

Based on the situation you've described, I strongly advise against a DIY approach and recommend you call a professional remediation company immediately. The fact that the mold is a large patch, has a strong, persistent odour, and has spread deeper into the wall structure indicates a significant infestation that surface cleaning cannot address.

The UAE's hot and humid climate, combined with year-round AC use, creates a perfect environment for mold growth. The AC leak you mentioned is the primary moisture source, and until that is professionally repaired, the problem will continue to recur, even if you clean the surface. The wall cavity likely has extensive contamination that requires specialized equipment to safely remove and dry. Disturbing black mold yourself can aerosolize highly allergenic and potentially toxic spores, contaminating your entire living space and posing a health risk.

In Dubai, professional mold remediation for a single wall typically involves containment with negative air pressure, HEPA filtration, removal of contaminated porous materials (like drywall and insulation), antimicrobial treatment, and, crucially, identifying and rectifying the moisture source (the AC leak). For a job of this nature, you should expect a rough cost ranging from AED 1,500 to AED 4,000, depending on the extent of the damage behind the wall and the AC repair required.

For a proper assessment and a definitive solution that addresses both the moisture issue and the contamination, you should contact a certified professional. I recommend calling Saniservice at 800-MOLDS (800-66537) or emailing hello@saniservice.com. They can provide a precise inspection and quote to resolve this safely and effectively.
