Is AC leak causing mold I can clean myself?« Back to Previous Page

Based on your description, this is a classic case of mold growth caused by a persistent AC condensate leak, a very common issue in Dubai due to our high humidity and year-round reliance on air conditioning. The black spots are almost certainly mold, thriving in the damp, cellulose-rich environment of your wall.

Attempting a DIY cleanup with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall and plaster, as it only bleaches the surface mold without killing the roots (hyphae) deep within the material. It also introduces excess moisture, potentially exacerbating the problem. More critically, improper cleaning can aerosolize mold spores, spreading the contamination to other areas of your apartment and posing a health risk.

The correct protocol involves two critical steps. First, a professional must stop the source of the moisture by repairing the AC leak. Second, the mold must be properly remediated. This requires isolating the area, using HEPA filtration to capture airborne spores, safely removing and disposing of the affected porous materials (e.g., the section of damaged drywall), and then hygienizing the underlying structure with EPA-approved antimicrobial agents.

Given the spread you've described, this is not a surface-level issue. Professional inspection and remediation are essential to ensure it is resolved safely and completely, in line with best practices for indoor environmental quality. For a thorough assessment and a compliant remediation plan, I recommend you contact the experts at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
