AC leak causing black mold—professional treatment cost in Dubai?« Back to Previous Page

That black mold returning after cleaning indicates it has penetrated the porous materials, likely the drywall and carpet backing. Given Dubai's high humidity, this type of AC condensation leak creates a persistent damp environment where mold thrives.

For a leak spreading behind skirting boards, professional remediation is strongly advised. The cost is not fixed; it depends entirely on the extent of the hidden damage. The primary cost drivers are the square meterage of contaminated material (drywall, carpet) that requires removal and replacement, and the number of air handling units needing containment for HEPA vacuuming and antimicrobial treatment.

You can expect a reputable company to first conduct a moisture mapping assessment to determine the full scope. For a contained bedroom leak, treatment often involves setting up negative air pressure containment, removing the affected skirting boards and sections of drywall, HEPA vacuuming the area, and applying an antimicrobial coating. The final and most significant cost is the reinstatement—replacing the drywall, repainting, and reinstalling skirting boards.

Always request a detailed scope of work and cost breakdown before any treatment begins. A proper company will also recommend post-remediation verification testing to confirm the space is returned to a normal fungal ecology. For a standard bedroom, budget for a comprehensive job that includes both remediation and rebuilding.
