Black mold in Dubai AC: DIY or professional removal cost?« Back to Previous Page

A leak and visible mold growth behind a wardrobe in Jumeirah is a common issue here, but it requires a professional assessment. The constant humidity and year-round AC use in Dubai create ideal conditions for mold to thrive inside wall cavities where a simple surface clean can't reach. The damp smell confirms there's an active moisture source.

For a patch that size, DIY bleach is not recommended. Bleach only removes surface discoloration on non-porous materials and does not address the root cause or kill the mold's roots (hyphae) embedded in porous drywall or plaster. It can also irritate your airways during application. The primary job is fixing the AC leak first—without that, the mold will return regardless of cleaning.

Professional remediation is advised for this scenario. The process involves isolating the area, removing affected porous materials like contaminated drywall, HEPA vacuuming, and antimicrobial treatment to address hidden growth. Companies with their own microbiology lab can also take surface or air samples to identify the species and confirm the spore count has returned to normal indoor levels after cleanup, which is the only way to verify the job is done correctly.

Cost is determined by the extent of contamination behind the wall, which isn't visible yet. You'll need a diagnosis of the leak's source and an inspection of the wall cavity to get an accurate scope of work. Reputable providers should offer this initial assessment to give you a clear picture before any work begins.
