Mold on ceiling from AC leak: DIY or professional in Dubai?« Back to Previous Page

Based on the symptoms you describe – a growing mold patch on the majlis ceiling coinciding with high humidity – this is almost certainly a condensate drain line blockage or a leak from the AC unit in the ceiling void. In Dubai's climate, this is a very common issue.

Professionally, I strongly advise against a DIY approach. Applying sealant or just cleaning the visible mold is a temporary fix that addresses the symptom, not the root cause. The moisture source must be identified and repaired first. Furthermore, Dubai Municipality and the Dubai Civil Defence have strict guidelines regarding building integrity and indoor air quality. Unlicensed work, especially involving concealed AC ductwork and electrical components, can lead to violations, particularly if improper remediation causes cross-contamination or the issue escalates.

A professional assessment (typically costing between AED 500 - 1000 for a thorough inspection including moisture mapping and air quality sampling) will pinpoint the exact leak source, assess the extent of mold growth within the ceiling void (which is always worse than what's visible), and provide a compliant remediation protocol. This ensures the repair is done to standard, preventing recurrence and potential health issues from mycotoxin exposure.
