Black mold from AC: DIY bleach fix or call pro in Dubai?« Back to Previous Page

For a leak that's been active for months with visible growth and health symptoms, this is a professional-level job. The wall cavity behind the wardrobe likely has extensive, concealed mold growth that bleach cannot effectively address. Bleach only removes surface discoloration on non-porous materials; it does not penetrate drywall or wood to kill the root structure, and the moisture from the bleach can actually feed further growth.

Your symptoms are a significant indicator. The persistent moisture from an AC leak in Dubai's climate creates an ideal environment for mold, and the stuffy noses are a common reaction to the elevated spore levels.

The remediation process must start by fixing the AC leak permanently. Then, the affected section of drywall and any soaked insulation must be removed under containment to prevent spreading spores. All surfaces are then HEPA-vacuumed and professionally cleaned with EPA-approved antimicrobials, not bleach. Finally, the area is dried with industrial equipment to ensure no moisture remains before rebuilding.

Given the scale you describe and the health impact, a professional assessment is strongly advised. Reputable firms provide a detailed scope of work and cost estimate after an inspection. For a single affected room, costs are variable and depend entirely on the extent of the damage behind the wall; always request a breakdown of the proposed remediation steps.
