AC leak caused mold behind wardrobe: DIY or professional?« Back to Previous Page

Given the description of a long-term leak and visible black splotches spreading, this requires professional remediation. The damp, heavy air and allergy symptoms are strong indicators of an active mold colony, which bleach cannot adequately address. Bleach only removes surface discoloration on non-porous materials; it cannot reach the mold growing deep within porous wall materials like gypsum board, which is likely in your villa. Furthermore, the AC unit itself is a probable source of contamination that needs specialized cleaning.

The combination of Dubai's high humidity and constant AC use creates a perfect environment for mold to thrive inside wall cavities from such a leak. A proper remediation involves isolating the area, safely removing and disposing of contaminated porous materials (like the affected drywall and insulation), HEPA vacuuming, and treating the underlying structure with professional-grade antimicrobial solutions. Crucially, the root cause—the AC leak—must be repaired by an HVAC technician to prevent immediate recurrence.

For a job of this nature, involving hidden wall damage and potential HVAC contamination, the process is not typically a simple per-room flat fee. The final cost is determined by the extent of the damage discovered during the inspection. You should request a detailed assessment from a certified remediation provider. A reputable company will provide a scope of work that includes containment procedures, removal protocols, and post-remediation verification, often with air or surface testing, to confirm the environment has been returned to a healthy state.
