Black mold under AC: DIY clean or call Dubai pro?« Back to Previous Page

For a dinner plate-sized patch of black mold under a carpet caused by a persistent AC leak, calling a professional is strongly recommended. The visible mold is likely just the surface manifestation; the water has almost certainly seeped into the carpet underlay and possibly the subfloor, creating a larger hidden reservoir of contamination that DIY surface cleaning cannot address.

Bleach is ineffective on porous materials and can actually worsen indoor air quality by releasing harmful fumes without killing the mold roots. Our climate is the main driver here—Dubai's high humidity and year-round AC use create perfect conditions for rapid mold proliferation, especially when a moisture source like a leak is present.

A proper remediation involves identifying and fixing the AC leak first to stop the moisture source. The process then requires removing and disposing of the contaminated carpet and underlay, HEPA-vacuuming the area, and applying EPA-approved antimicrobial solutions to the subfloor. The cost for this type of targeted remediation is typically more accessible than a full-home treatment, but you should request an on-site assessment for an accurate scope and quote. Any reputable company will provide a detailed plan and can often arrange for a post-remediation verification test from an independent lab to confirm the area is truly clean and safe.
