AC leak causing mold: DIY bleach or professional in Dubai?« Back to Previous Page

The black spots returning after wiping indicate active mold growth, which is common from AC condensate leaks in Dubai's humid climate. Bleach only removes surface discoloration, not the root mold penetrating porous materials like drywall or paint.

For a recurring leak and visible spreading, a professional assessment is necessary. The primary action is to stop the moisture source—have an AC technician repair the leak immediately to prevent further damage. Mold remediation then focuses on the affected wall. The cost for a small area is typically moderate, but it depends on the extent of hidden damage behind the headboard, which often requires cutting out and replacing the contaminated section.

In many cases, simply applying a biocide is insufficient if the material itself is compromised. Dubai's high humidity can also cause mold to regrow if the area isn't properly dried and sealed post-repair. A reputable company will use moisture meters to confirm the wall is dry and may recommend air quality testing afterward to confirm spore levels have returned to normal, a service our own microbiology lab provides. For a confirmed, contained leak, the overall process is generally straightforward.
