AC leak causing mold in bedroom: DIY or professional?« Back to Previous Page

That sounds like a classic case of AC condensation leading to mold growth, a very common issue in Dubai due to the constant humidity and AC use. The black speckles and your physical symptoms strongly suggest this requires more than a surface clean.

For a leak that's persisted for months, the moisture has likely penetrated deep into the wall and possibly behind it. Bleach only removes surface discoloration and does not address the root moisture problem or kill the mold's root structure (hyphae). In our climate, it will almost certainly return within weeks. The damp smell and itchy throat indicate active spores are already in your air.

This is a job for a professional. They will first identify and repair the AC leak—the critical first step. Then, they'll assess the full extent of the damage, which often involves removing baseboards or sections of drywall to properly dry and treat the cavity. They use industrial HEPA air scrubbers to contain spores and professional-grade antimicrobials. For a single room with a contained leak, the remediation process itself is typically a one to two-day job, but the total timeline depends on drying times.

The cost is driven by the extent of demolition required for proper drying and the square footage of contamination. For a contained area behind a wardrobe, you are likely looking at a project that involves localized removal of affected materials, structural drying, and treatment. Always request a detailed assessment and quote that includes the AC repair, containment procedures, and post-remediation verification to ensure the problem is resolved.
