Mold in Dubai AC: professional cost and DIY fix?« Back to Previous Page

The black speckles and recurring symptoms point strongly to a mold issue, a common problem in Dubai due to the high humidity and constant AC use, which creates ideal conditions for growth. The leak from your AC unit is the primary moisture source that must be fixed first.

Handling this yourself with bleach is not recommended for several reasons. Bleach is ineffective on porous surfaces like drywall, as it only bleaches the surface mold without killing the roots deep within. It can also aggravate the problem by releasing a high volume of spores into your bedroom air during cleaning. For a spread behind a wardrobe, the infestation is likely more extensive than what is visible.

Professional assessment is necessary. A proper inspection will identify the exact species (to confirm if it's the notorious Stachybotrys or another type) and the full extent of the contamination using moisture meters and borescopes. The remediation process itself involves containment with negative air pressure, HEPA filtration, safe removal of affected materials, and antimicrobial treatment to prevent regrowth.

Cost is determined by the scope of work—the size of the affected area, the materials involved, and the required containment. For a situation involving wall damage and an AC leak, expect the project to be more involved than a simple surface clean. Reputable companies provide detailed assessments and quotes only after an on-site inspection. The investment is justified by properly addressing the health concern and the source of the problem, preventing it from recurring and potentially causing more significant structural damage.
