Need pro for AC mold leak in Dubai villa? Cost?« Back to Previous Page

The AC in our Jumeirah villa has been leaking into the wall behind it, and we’ve just discovered a pretty large patch of black mold there, about the size of a dinner plate. We’ve been wiping it with bleach, but it keeps coming back after a few days and the dampness is still there. Is this something I can handle myself with a good mold spray from ACE, or do I absolutely need to call a professional for this kind of job, and roughly what should I expect to pay for a fix like this in Dubai?

Based on your description, you absolutely need to call a professional. The recurring mold growth, despite using bleach, is a classic indicator of a deeper, unresolved issue. Bleach is a surface-level biocide that does not address the moisture source or penetrate porous materials like drywall and insulation, which are likely saturated.

The dampness behind the AC unit is the critical problem. This is typically caused by a clogged condensate drain line or a faulty drip pan, both common in Dubai's climate where AC systems run year-round and generate significant condensation. Until this leak is professionally identified and repaired, the mold will continue to return.

Attempting a DIY fix with a retail mold spray is insufficient and can be hazardous. Disturbing the mold colony can aerosolize toxic spores, spreading the contamination throughout your villa's air system. Furthermore, proper remediation requires the removal and replacement of the water-damaged building materials, HEPA vacuuming, and antimicrobial treatment to ensure it is eradicated at the root.

For a job of this scale in a Jumeirah villa, involving an AC leak and structural moisture, you should expect a professional remediation process. This includes a detailed inspection, moisture mapping, containment setup, safe removal of contaminated materials, hygienization, and post-remediation verification. Costs in Dubai can vary based on the extent of damage but for a localized area like this, you could be looking at a range starting from AED 2,500 to AED 5,000+, which includes the mold remediation and addressing the AC leak source.

Given the health risks and potential for structural damage, I strongly recommend you stop applying bleach and contact a certified specialist immediately.
