Shuold I DIY clean closet mold or hire a pro?« Back to Previous Page

A leak from an AC unit is the primary issue that must be fixed first; the mold is a symptom. For a small patch under 1 square meter, a DIY approach can be effective if you address the source. However, given the location inside a closet and the persistent humidity, the visible mold is likely just a fraction of what’s present behind the wall or in the AC drip pan.

In Dubai’s climate, high humidity and constant AC use create perfect conditions for mold in enclosed spaces. The musty smell confirms it's active. Cleaning the surface with a vinegar solution (undiluted, in a spray bottle) can kill surface growth, but it won't address the moisture trapped within the drywall or the AC system itself.

For a proper remediation, the wall cavity needs inspection for hidden growth, the AC drain line must be cleared and sanitized, and the area dried with industrial equipment to prevent immediate regrowth. This requires professional-grade antimicrobials and moisture meters to verify the wall is dry.

Cost varies significantly based on the extent of damage, but for a contained closet area, expect a professional assessment to be the first step. They can provide a scope of work and a fixed price for remediation only after identifying the full extent of the moisture and mold, which is a standard practice for reputable firms in the UAE.
