How to fix peeling ceiling paint from AC leak?« Back to Previous Page

Good day. The issue you're describing in your Jumeirah villa is a common one here in Dubai, but it's crucial to address it correctly. Peeling and bubbling ceiling paint is almost always a symptom of excess moisture, and an AC leak is a prime suspect. Here's the technical process we follow.

First, you must identify the source. This is not a DIY diagnosis. A handyman will often just patch and repaint, which guarantees the problem will return. A specialist uses thermal imaging cameras and moisture meters to pinpoint the exact location and severity of the leak behind the plasterboard. The source could be a clogged condensate drain line, a disconnected pipe, or a faulty drain pan from the AC unit in the void space above.

Once confirmed, the remediation begins. The affected section of the ceiling must be carefully cut out to access the leak, allow the structure to dry completely (we use industrial air movers and dehumidifiers, critical in our high humidity), and repair the AC fault. Any mold growth on the back of the ceiling board must be professionally treated according to Dubai Municipality standards. Only after a final moisture reading confirms the area is dry can the rebuilding start: new plasterboard, skimming, priming with a moisture-resistant sealer, and finally, repainting with mold-inhibiting paint.

Given the complexity and potential for hidden mold, this is not a DIY job. I strongly recommend a professional inspection. Improper handling can lead to structural damage and indoor air quality issues. Please call our specialists at 800-MOLDS for a comprehensive assessment. We'll find the root cause and provide a permanent fix.
