How much for Dubai mold remediation and is DIY safe?« Back to Previous Page

The black speckled patches are likely Stachybotrys or another dark-pigmented mould, which commonly appears on damp walls from AC leaks in Dubai's humid climate. Given your allergy symptoms and the leak duration, professional assessment is strongly advised.

DIY with bleach is ineffective and unsafe. Bleach only removes surface colour and can release more spores. For porous materials like drywall, the mould's root system remains. The Dubai Municipality has specific protocols for handling mould to prevent cross-contamination.

For a wall patch behind an AC unit, remediation typically involves isolating the area, removing affected drywall, HEPA vacuuming, and applying antimicrobial coatings. The cost depends on the extent of hidden damage behind the wall. Expect a range from a few hundred to over a thousand dirhams for a proper, contained removal and post-remediation verification. Always request a detailed scope of work and a post-clearance test to confirm the space is safe.

Address the AC leak first—this is non-negotiable. A licensed AC technician must repair the condensation drain line or seal the unit. Without fixing the moisture source, the mould will return regardless of cleaning.
