How to fix AC leak and ceiling damage in Dubai?« Back to Previous Page

Based on your description, this is a classic case of an AC condensate drain line leak, extremely common in Mirdif villas due to our high humidity and the attic spaces getting incredibly hot, causing condensation. Proper diagnosis and repair are critical to prevent mold growth, which is a serious health hazard here.

The diagnostic steps involve a thorough inspection of the attic space. A certified technician will first check the AC drain pan for cracks or overflow and then use a nitrogen gas pressure test on the PVC drain line to locate any blockages or disconnections. We also inspect the insulation on the suction lines, as sweating due to poor insulation can mimic a drain leak.

For the repair, the blocked or damaged section of the drain line is cleared or replaced. The drain pan is checked and resealed or swapped if cracked. Crucially, we always treat the area for microbial growth. Simply repainting over the stain is a major violation of Dubai Municipality's public health guidelines, as it traps moisture and mold spores, creating an indoor air quality issue.

The ceiling repair cannot begin until the leak is 100% confirmed fixed and the area is completely dry. The damaged gypsum board must be cut out, the cavity professionally hygienized to kill any mold, and then new board installed, taped, and painted to match.

This is not a DIY job. Incorrect handling can spread mold spores throughout your HVAC system. For a proper assessment and remediation that complies with UAE standards, please call our certified team at 800-MOLDS or email hello@saniservice.com for a detailed inspection report and quote.
