AC leaking condensation causing mold, who to call?« Back to Previous Page

The AC in our villa in Jumeirah 3 seems to be leaking condensation into the wall behind it, and now we're getting black spots of mold on the skirting board and a really damp smell in the master bedroom. We had the AC unit serviced last summer, but this is a new issue that popped up over the last few weeks with the humidity. What's the best way to fix the existing mold and, more importantly, who should I call to properly seal the AC unit so this doesn't keep happening every year?

The issue you're describing is a classic and very serious problem in Dubai, particularly during the high-humidity summer months. The black spots on the skirting board are a visible sign of a much larger microbial colony, likely growing inside the wall cavity due to the constant moisture from the AC condensate leak. This is not just a cosmetic issue; it is a health hazard and can compromise the structural integrity of the building materials.

The correct remediation process is a two-step approach that must be handled by certified professionals. First, the active mold growth must be professionally assessed and remediated. This involves containment of the affected area, HEPA vacuuming, antimicrobial treatment, and safe disposal of contaminated porous materials like the skirting board and potentially the drywall. Crucially, the source of the moisture must be permanently fixed. This requires an HVAC specialist to properly reseal the condensate drain line connection and the unit's installation point to prevent future leakage. A standard AC service often does not address these installation flaws.

Given the climate-driven nature of this problem, a company like Saniservice is specifically equipped to handle both the inspection and remediation. We are experts in UAE-specific mold issues and follow strict protocols to ensure the problem is solved at its root. For a situation like this, I strongly recommend you call for a professional inspection immediately.
