How to safely remove mold and check behind walls?« Back to Previous Page

My kids have been coughing and I suspect it's from the mold I just found behind the wardrobe in our master bedroom. We've lived here for 2 years and just noticed it when we moved the furniture to rearrange the room; it's a large black patch on the wall. This must have been growing slowly for ages, especially with the AC condensation. What's the best way to get rid of this safely and who should I call to check if it's a bigger problem behind the walls?

For a patch that size and with health symptoms present, professional assessment is the safest first step. The black patch indicates active growth, and Dubai's high humidity combined with AC condensation creates ideal conditions for mold to penetrate porous materials like drywall.

Do not attempt to clean it yourself with bleach or other household products. Disturbing it will release spores that can spread throughout the room and HVAC system, potentially worsening your children's coughing. The priority is identifying and fixing the moisture source—likely a condensation leak from the AC unit's drain line or a small plumbing leak inside the wall.

Call a certified mold inspection company that uses borescopes to see inside the wall cavity without unnecessary demolition. They should also conduct air quality testing to measure spore levels in the bedroom compared to the outside. This data is critical to understand the full scope. In the UAE, remediation companies should follow IICRC S520 standards for containment and removal to prevent cross-contamination.

For remediation, they will set up containment, use HEPA filtration, and safely remove the affected wall section. After removal, the underlying cause must be fixed and the area dried with professional-grade equipment before any rebuilding. A post-remediation verification test from a third-party lab is the only way to confirm the space is truly safe.
