Black mold from AC: DIY fix or hire pro in Dubai?« Back to Previous Page

This situation requires professional remediation, not a DIY approach. The recurring mould and strong earthy smell indicate a deep-seated infestation within your wall cavity, which vinegar cannot address. In Dubai's high humidity, the moisture source—likely a clogged AC condensate drain line—must be fixed first, or the mould will always return.

Hiring the first company online is risky. The market has significant variation in quality. Look for a provider that offers a clear process: identifying and stopping the moisture source, containing the area to prevent spore spread, physically removing contaminated materials like the damp wallpaper, HEPA vacuuming, and applying antimicrobial treatments. Crucially, they should provide before-and-after testing from an accredited microbiology lab to verify the spore count has been returned to safe, ambient levels.

You cannot get a fair price without an on-site assessment. The cost depends on the extent of the damage behind the wall, which is hidden. Reputable companies provide free inspections and detailed quotes. Avoid any service that gives a fixed price over the phone or promises to "eliminate" mould entirely; the goal is to reduce it to a level that is not harmful to health.

Given the potential health risks from airborne spores, especially for children or those with allergies, this is not a project to handle yourself. Proper remediation requires containment barriers, negative air machines, and professional-grade PPE to protect you and your family from exposure during the process.
