How to permanently fix AC mold in old Bur Dubai flat?« Back to Previous Page

Given the age of your building in Bur Dubai and the persistent leak, you're likely dealing with a significant mold issue, not just a surface stain. The black spots are a major red flag, and your wife's symptoms (stuffy nose, headaches) are classic indicators of mold exposure.

The permanent fix is a two-part process: professional remediation followed by addressing the root cause.

First, STOP using that AC unit. The mold colony in the ceiling and likely within the AC unit itself is now aerosolizing spores directly into your bedroom air. For a situation this advanced, DIY cleaning is ineffective and hazardous, as it will disturb the colony and massively increase spore concentration.

You need a certified mold inspection. We use thermal imaging cameras and borescopes to assess the full extent of the infestation inside your ceiling void and AC drip pan/ducting, which is almost always worse than it appears. Remediation isn't just wiping the visible spots; it involves sealing the area, using HEPA filtration to capture airborne spores, and safely removing all contaminated materials. In the UAE, reputable companies follow IICRC S520 standards for this precise work.

The permanent solution, however, is fixing the water source. In old Dubai buildings, this is typically a clogged condensate drain line or a cracked drain pan inside the AC unit. A certified HVAC technician must fully service the unit, clear the drain line with a vet, and ensure proper drainage. Afterwards, applying an EPA-approved antimicrobial coating inside the unit and treated area prevents regrowth.

Your health concerns are valid. For a proper assessment and a guaranteed solution, please call our specialists at 800-MOLDS (800-66537) or email hello@saniservice.com. We can provide a detailed scope of work that addresses both the contamination and the AC fault permanently.
