Mold behind bedroom wall: DIY or professional removal?« Back to Previous Page

That wall likely has a moisture issue from condensation or a slow leak, which is common in Dubai's climate. A patch that size (1m) with a persistent damp smell indicates an established colony, not just surface growth. Bleach is ineffective on porous surfaces like drywall—it only removes surface color, not the root structure.

For a villa in Al Barsha, professional assessment is strongly recommended. The mold behind the wardrobe suggests hidden moisture, possibly from the AC system's condensate drain line, high indoor humidity, or an external wall leak. A professional uses moisture meters and thermal cameras to find the source, as just cleaning visible mold will lead to rapid regrowth.

The cost depends entirely on the moisture source and extent of damage. If the drywall is saturated, replacement is necessary. Expect a process that includes containment, HEPA vacuuming, antimicrobial treatment, and addressing the root cause to prevent recurrence. Companies with their own microbiology labs can verify the species and confirm remediation was successful through post-clearance testing.

For a temporary measure until assessment, improve airflow around the area, but avoid disturbing the mold yourself. DIY attempts often spread spores throughout the home.
