How to clean and prevent mold from AC leak?« Back to Previous Page

Based on your description, that's a classic case of "long mold" growth, most likely Stachybotrys chartarum or another toxic species, fueled by the constant moisture from your AC leak. This isn't something to take lightly, especially with Dubai's humidity levels rising again.

First, stop the source. You must get that AC unit serviced and repaired by a certified HVAC technician to prevent further water intrusion. No cleaning will be effective if the leak continues.

For the visible mold on a non-porous surface like a painted wall, a solution of detergent and water can remove the surface growth. However, given the duration (a month) and the location (behind a curtain, a classic hidden spot), the moisture has likely penetrated the gypsum board and possibly the insulation behind it. Surface cleaning will only provide a temporary cosmetic fix. The mold will absolutely return because the root problem is inside the wall cavity.

In the UAE, improper remediation can violate health and safety standards for indoor air quality. Disturbing the mold without proper containment and air filtration will aerosolize the spores, spreading the contamination throughout your bedroom and potentially your entire home, posing a significant health risk.

For a situation like this, a professional inspection is non-negotiable. We use moisture meters and thermal imaging cameras to assess the full extent of the water damage hidden within the structure. Remediation involves removing and disposing of the contaminated porous materials (drywall, insulation) under containment with negative air pressure and HEPA filtration, followed by a thorough hygienization of the area.
