AC leak causing mold in Dubai villa: cost to fix?« Back to Previous Page

Based on the symptoms you've described—a recurring AC leak, persistent black spots, and exacerbated allergies—this is a classic case of mold growth driven by Dubai's high humidity and condensation issues. The black spots are likely Stachybotrys chartarum (black mold) or Aspergillus, both of which are common here and known to cause significant allergic reactions and respiratory issues.

Attempting to wipe it away is a temporary fix that disturbs the spores, potentially spreading them and worsening air quality. The root cause is the moisture from the AC leak, which will continue to fuel mold growth behind the wall, likely in the insulation and internal structure.

For a professional response, the process is two-fold. First, a certified inspection (cost range: AED 800 - AED 1,500) involves moisture mapping, thermal imaging to find the full extent of water damage, and air/tape-lift sampling to identify the mold species and concentration. This is crucial for developing a proper remediation protocol.

Remediation for a single room typically ranges from AED 3,000 to AED 8,000. The cost depends on the extent of the infestation within the wall cavity, which requires controlled demolition, removal of contaminated materials, HEPA-vacuuming, antimicrobial application, and finally, repairing the AC drain line to prevent recurrence. DIY methods with cleaners are ineffective against entrenched growth and do not address the hidden contamination or the source leak.

Given the health risks and structural implications, hiring a professional is strongly recommended. We adhere to Dubai Municipality and EPA guidelines for safe, effective removal. For an immediate assessment and quote, please call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com.
