Mold from AC leak: DIY or professional removal?« Back to Previous Page

That black spot pattern is a classic sign of chronic moisture from an AC condensate leak, and Dubai's high humidity accelerates its growth. You're right to connect the two.

For a small, surface-level patch (under one square meter), a thorough DIY approach can be effective if you address the source first. The leak must be repaired; otherwise, the mold will return. Use a mold-specific cleaner from a hardware store, not just bleach, and wear an N95 mask, gloves, and goggles during cleaning. Seal the area off from the rest of the room to prevent spore dispersal.

However, given its location behind a wardrobe, this situation often warrants a professional. The wall cavity or backing board may be saturated, harboring hidden growth that surface cleaning won't reach. A proper remediation involves isolating the area, removing contaminated porous materials like drywall or insulation, and using HEPA filtration to clean the air. The cost for a professional service is not fixed; it depends entirely on the extent of the hidden damage. You should request an on-site assessment for an accurate scope and quote. Companies with their own microbiology lab can also test to confirm the type of mold and verify it has been removed after remediation, which is a strong indicator of a science-driven approach.
