DIY methods like bleach from ACE are strongly discouraged. Bleach doesn’t kill mold on porous surfaces and its high water content can actually feed the root system deeper in the wall, making the problem come back worse. It also poses a serious health risk in an enclosed space.

Under UAE regulations, particularly from Dubai Municipality, proper containment and air scrubbing are mandatory for safe removal to prevent cross-contamination to other areas of your home. A pro will use industrial HEPA filtration and specialized antimicrobials, not bleach.

For a patch the size you mention, if it’s contained to just the surface of one wall, a rough cost estimate for professional remediation could range from AED 1,500 to AED 3,500. This would include a full inspection, moisture mapping, safe removal, and post-remediation verification to ensure it’s truly gone. The only way to get an accurate quote is to have it assessed.

Given the potential health risks and property damage, calling a pro is the only smart move.
