Mold under carpet from AC leak: landlord or professional first?« Back to Previous Page

Our AC unit in the bedroom closet has been leaking a bit for the last few weeks, and now I've just pulled back the corner of the carpet and found a patch of black and green mold on the concrete underneath. I'm really worried it's spread further under the carpet and might be affecting our health. What's the most effective way to handle this mold issue here in Dubai, and should I call my landlord or a professional cleaning company first?

The situation you've described is a serious indoor environmental concern common in Dubai due to our high humidity and constant AC operation, which creates ideal conditions for mold proliferation. The visible patch is a significant indicator; however, mold growth under carpets from a chronic AC condensate leak is typically far more extensive than what is immediately visible. The mold colony will have spread through the carpet backing and underlay, releasing spores and microbial volatile organic compounds (mVOCs) into your indoor air, which can indeed affect respiratory health.

Your first call must be to your landlord or property management company. According to typical tenancy contracts and Dubai Municipality regulations, landlords are responsible for maintaining the property's structural integrity and addressing issues like faulty AC systems that lead to secondary damage. Inform them in writing, with photos, and request immediate action to repair the AC leak at its source.

However, for the actual mold remediation, do not use a standard cleaning company. This requires a professional environmental hygienist. General cleaners lack the technical expertise for proper containment, antimicrobial application, and removal protocols to prevent cross-contamination. We use techniques like moisture mapping with thermal imaging and hygrometers to determine the full extent, then implement engineering controls (negative air pressure containment, HEPA filtration) to safely remove the contaminated materials and treat the concrete subfloor.

For a certified inspection and a remediation protocol that ensures the problem is resolved safely and completely, I strongly recommend contacting our specialists at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com. We can provide a detailed report for your landlord and execute the necessary remediation to restore a healthy indoor environment.
