AC mold cleanup: DIY with bleach or hire a pro?« Back to Previous Page

A small patch from a recent leak might be manageable yourself, but given the location behind a wardrobe and its growth over a month, professional assessment is strongly recommended. The primary concern is that mold often grows deeper into drywall and insulation than what's visible on the surface; a simple surface wipe may not address the root problem.

For DIY on a very small area (under 1 sq. ft.), a detergent solution is more effective and safer than bleach, which doesn't prevent regrowth and can damage porous surfaces. However, the Dubai climate creates a constant risk of recurrence. The high humidity and year-round AC use mean any residual moisture or spores will quickly lead to new growth if not properly addressed.

A professional inspection, like those conducted by IICRC-certified firms, identifies the moisture source—in this case, the AC leak—and the full extent of contamination, often using moisture meters and borescopes. They then perform containment to prevent spores from spreading to other rooms during remediation. For a single room, the process typically involves removing affected drywall, treating the cavity, and applying antimicrobial solutions. The final, critical step is a post-remediation verification test from an independent lab to confirm the air and surfaces are clear, which is the only way to be certain the problem is resolved.
