AC leak causing mold; who to call for fix?« Back to Previous Page

The situation you're describing is a classic and very common issue in Dubai, exacerbated by our high humidity levels and year-round reliance on AC systems. The black spots along the skirting board are almost certainly the initial stages of mold colonization, likely Cladosporium or Aspergillus, which thrive in the damp, cellulose-rich environment of wet carpet and backing.

For immediate action, your priority is to stop the moisture source. I strongly advise you to shut off the AC unit for that zone to prevent further leakage. Do not attempt to apply bleach or store-bought solutions, as these only remove surface discoloration and can exacerbate spore dispersal. The moisture has likely wicked up the drywall behind the skirting board, creating a hidden reservoir for mold growth that you cannot see.

This scenario requires a two-pronged professional approach. First, you need a certified HVAC technician to diagnose and rectify the AC leak. Common causes in our region are clogged condensate drain lines due to dust and microbial growth, or a malfunctioning condensate pump. They will need to clear the line, treat it with an algacide, and ensure proper drainage.

Secondly, the affected building materials must be assessed by a certified mold inspector. The Dubai Municipality has specific guidelines for indoor environmental quality, and improper handling can spread contamination. A professional company like Saniservice will use moisture meters and thermal imaging to determine the full extent of the water damage, perform air and surface sampling to identify the mold species, and execute a controlled remediation protocol. This includes isolating the area, using HEPA filtration, and properly disposing of non-salvageable porous materials like the carpet section and potentially the lower portion of the drywall.

To properly address both the symptom and the cause, you should call a professional remediation company that can also coordinate the HVAC repair. For a comprehensive inspection and certified remediation, I recommend contacting Saniservice at 800-MOLDS (800-66537) or hello@saniservice.com. They can provide a detailed assessment and ensure the problem is resolved in compliance with local standards, preventing health issues and structural damage.
