Black mold in Dubai AC closet: hire professional and cost?« Back to Previous Page

Based on your description, yes, you should hire a professional. Vinegar is a surface-level treatment and often fails on porous materials like drywall, especially when the moisture source is ongoing. The fact it returned worse indicates an active moisture problem, likely from a small AC condensate leak or excessive humidity in that enclosed space—both very common issues in Dubai's climate.

For a suspected AC leak, remediation is a two-part process: first, an HVAC technician must locate and repair the leak to stop the moisture. Then, a mold remediation company handles the contaminated materials. Testing is often secondary; the visible growth and moisture source are the primary concerns. A professional inspection will identify the exact moisture origin and the extent of the spread, which can be wider than what's visible.

Treatment cost depends entirely on the scope. A small, contained area like a single closet is a relatively minor project, but pricing varies significantly based on the company's methodology, the materials affected, and whether the AC repair is included. Expect to receive quotes for assessment and remediation as separate items. Always choose a company that provides a clear scope of work, uses containment to prevent cross-contamination, and can verify results with post-remediation testing from an independent lab.
