Mold on wall from AC leak: professional needed? Cost?« Back to Previous Page

Based on your description, this is a textbook case of mold growth caused by a persistent AC condensate leak, a very common issue in Dubai due to our high humidity and year-round AC operation. The black spots are likely Stachybotrys chartarum (black mold) or Aspergillus, which thrive in the constant moisture from the leak, especially in the stagnant, hidden space behind furniture.

Yes, you absolutely need a professional mold remediation company. This is not a surface cleaning job. The moisture has likely penetrated the drywall and possibly the wall structure itself. Disturbing it incorrectly can aerosolize toxic spores, significantly increasing your risk of respiratory issues, allergic reactions, and other health effects. DIY attempts often spread the contamination throughout the apartment.

A proper remediation process involves: 1) Containment of the area with negative air pressure to prevent cross-contamination. 2) Professional HEPA-filtered air scrubbing. 3) Safe removal and disposal of contaminated porous materials like the affected drywall. 4) Hygienization of the underlying structure and adjacent areas with EPA-approved antimicrobials. 5) Identifying and rectifying the root cause—the AC drain line leak—to prevent immediate recurrence.

For a one-bedroom apartment in JVC, the cost is typically broken into inspection and remediation. A professional mold inspection and detailed report with air/o-surface sampling can range from AED 800 to AED 1,500. The remediation work for a localized area like this can start from approximately AED 3,000 to AED 7,000+, depending on the extent of the damage behind the wall and the required repairs.
