Black mold behind wardrobe: professional cost or DIY with bleach?« Back to Previous Page

That black mold patch behind your wardrobe is a common issue in Dubai apartments, especially with a leaking AC unit. The constant humidity and condensation from AC systems create an ideal environment for mold growth.

You should not attempt to clean this yourself with bleach. While bleach can remove surface discoloration on non-porous materials, it is ineffective on porous surfaces like drywall and can actually worsen the problem by adding moisture. The water in bleach soaks into the wall, feeding the mold's root system (hyphae) hidden within, causing it to regrow more aggressively.

The cost for professional remediation is not fixed; it depends entirely on the extent of the damage. The visible patch is often just the "bloom," with a larger colony likely growing inside the wall cavity from the persistent moisture. A proper remediation involves isolating the area, removing contaminated porous materials like drywall or insulation, HEPA vacuuming, and antimicrobial treatment of the structure. The AC leak must also be repaired by an HVAC technician to prevent immediate recurrence.

For an accurate assessment and quote, you need a professional inspection. They will check the wall's moisture content to determine the full scope and provide a scope of work. In Dubai, reputable companies follow standards like the IICRC S520 for mold remediation, which ensures the problem is properly contained and resolved.
