For a confined space like a closet, the remediation cost in a Dubai apartment can vary significantly based on the extent of the infestation behind the wall. A superficial cleaning will not address the root cause. A proper remediation process involves containment of the area with negative air pressure, HEPA filtration, removal and disposal of contaminated porous materials (e.g., drywall, insulation), hygienization of underlying structures with EPA-approved fungicides, and application of preventative coatings.

For a job of this described size, you should expect a realistic price range between AED 1,500 to AED 4,000. This estimate includes the initial inspection, lab analysis (if required), and the full remediation protocol. It is crucial to hire a company that follows UAE standards and provides a post-remediation verification report to ensure the job is done correctly.

Attempting a DIY fix with bleach is not recommended. Bleach is ineffective on porous surfaces and can exacerbate the problem by adding moisture. The underlying cause, likely insufficient insulation or a thermal bridge in the wall, must be identified to prevent recurrence.
