Mold from AC causing illness: DIY or professional in Dubai?« Back to Previous Page

Black spots behind a wardrobe from AC condensation are a common issue in Dubai's humid climate, and a constant stuffy nose is a classic symptom of exposure. The connection is very plausible.

For a small, visible patch (under one square meter), a careful DIY approach is possible. Use a vinegar solution or a dedicated mold cleaner from a hardware store, not just bleach. Bleach only removes surface color and doesn't kill the roots on porous surfaces like drywall. You must wear an N95 mask, gloves, and goggles to avoid inhaling spores during cleaning. The critical step is fixing the moisture source—wipe down the condensation line and ensure the AC drain is not blocked to prevent immediate regrowth.

However, given the location (behind a large furniture item) and the accompanying health symptom, a professional inspection is strongly recommended. Hidden mold inside the wall cavity from the condensation leak is likely, and disturbing it during DIY can aerosolize a large number of spores, worsening your husband's reaction. Professionals use containment barriers and HEPA filtration to prevent cross-contamination.

In Dubai, reputable remediation companies should provide a detailed protocol based on DM guidelines and, crucially, verification testing after cleanup to confirm the spore count in the air has returned to safe levels. The cost for assessment and remediation varies significantly based on the extent of the contamination, which can't be determined without moving the wardrobe and proper inspection. It is best to request an on-site assessment from a certified provider to understand the scope and get an accurate quotation.
