How quickly must I fix AC leak causing black mold?« Back to Previous Page

You need to address this immediately. The combination of a persistent AC leak and Dubai's high ambient humidity creates a perfect storm for rapid mold proliferation. Within 48-72 hours of water intrusion, mold can begin to colonize. After two weeks, the visible "small black patches" on the concrete indicate an established colony, and it is highly likely that there is more extensive growth within the carpet backing and padding that you cannot see.

The black coloration is a significant concern, as it often indicates the presence of Stachybotrys chartarum or Aspergillus niger, both of which are associated with serious health risks, including respiratory issues, allergic reactions, and mycotoxin exposure. The continuous operation of your AC unit will aerosolize these spores and distribute them throughout your bedroom and the rest of the home, escalating the health hazard.

Do not attempt to clean this yourself. Disturbing the mold without proper containment and air filtration will cause a massive release of spores. Your first step is to stop the source: put in that maintenance request to fix the AC condensate drain line immediately.

For the remediation, this requires professional intervention. The carpet and underlay must be carefully removed and disposed of. The concrete subfloor will need specialized antimicrobial treatment and drying to ensure the mold is eradicated at the root. In the UAE, reputable companies like Saniservice follow strict protocols for containment, removal, and post-remediation verification to ensure the problem is solved completely and safely.

I strongly recommend you get a professional inspection and remediation quote without delay. Contact Saniservice at 800-MOLDS (800-66537) or hello@saniservice.com to have a certified specialist assess the situation.
