AC mold in Dubai: DIY bleach clean or call pro?« Back to Previous Page

The black spots are likely mold growth fueled by the AC condensation leak and high Dubai humidity. For a small area (under one square foot), a DIY approach can be tried. Use a dedicated mold cleaner from a hardware store, not plain bleach, as bleach only removes surface discoloration and does not address the root problem. Scrub the affected wall surface thoroughly and fix the AC leak immediately to prevent recurrence.

However, given the leak has been ongoing for weeks and the mold is on a porous surface like drywall, professional assessment is strongly recommended. The visible spots are often just the surface manifestation; the hyphae (root structure) can penetrate deep into the wall. In Dubai's climate, this creates a persistent damp environment for rapid regrowth.

A proper remediation involves containing the area to prevent spore spread, removing affected porous materials if necessary, and using professional-grade biocides and HEPA vacuuming. For verification, a company with its own microbiology lab can provide before-and-after testing to confirm the space has been returned to a normal fungal ecology. This is particularly important for a bedroom, where you spend many hours breathing the air.
