Black mold from AC leak: DIY clean or professional inspection?« Back to Previous Page

Black specks from an AC leak in a Jumeirah villa should be professionally inspected, not cleaned with bleach. Bleach only removes surface colour and doesn't address the root cause or underlying moisture, often causing the mould to return more aggressively. In Dubai's high humidity, the constant condensation from a leaking AC unit creates a perfect environment for mould to grow deep into porous materials like drywall and wood.

For a two-bedroom villa, a professional inspection typically involves a thorough visual assessment, moisture mapping to identify the full extent of water damage, and, most critically, air and surface sampling sent to an independent microbiology lab. This lab analysis is essential—it identifies the specific mould species (e.g., whether it’s the more concerning Stachybotrys or common Cladosporium) and the airborne spore count, which dictates the necessary remediation protocol. The cost for this comprehensive service, including a detailed report with lab results, is a necessary diagnostic step.

DIY attempts often spread spores and miss hidden reservoirs. Given the persistent leak and visible growth over months, the problem is likely established. A proper inspection provides the data needed for an effective, permanent solution, which is crucial for indoor air quality, especially in bedrooms.
