AC leak caused mold; DIY clean or call professional?« Back to Previous Page

Based on your description, this is a situation that requires professional attention. A leak persisting for a month has created a significant moisture event, and the fact that the visible patches are at the wall-floor junction strongly suggests the water has wicked into the porous building materials—the drywall, the insulation behind it, and the concrete slab beneath the carpet. The persistent musty smell after a surface clean with vinegar confirms the mold growth is not superficial.

In Dubai's climate, where high ambient humidity is the norm, AC systems are critical for controlling indoor moisture through dehumidification. A leaking AC unit not only adds water directly but also fails to manage the humidity, creating a perfect breeding ground for mold. The spores can easily become airborne and spread through the AC ductwork to other parts of the home.

DIY cleaning with common household products like vinegar or bleach is insufficient. These solutions only address the surface stain and do not penetrate porous materials to kill the root structure (hyphae) of the mold. Furthermore, improper cleaning can agitate and aerosolize spores, increasing contamination.

UAE regulations and best practices for mold remediation, such as those outlined by the Dubai Municipality, emphasize containment, professional-grade antimicrobial application, and the safe removal of contaminated porous materials to prevent cross-contamination and protect occupant health.

Given the extent of potential hidden growth, a professional inspection is essential. We strongly recommend you contact a certified mold remediation company like Saniservice. Our experts use thermal imaging cameras and moisture meters to assess the full extent of the damage behind walls and under floors, followed by a protocol that includes containment, HEPA filtration, and proper disposal.
