How to permanently remove and prevent mold under AC leak?« Back to Previous Page

The issue you're describing is extremely common in Dubai due to our high humidity and AC-dependent climate. Wiping with vinegar is a temporary fix for a non-porous surface, but it's ineffective on porous concrete and does not address the root cause.

Here is the correct, permanent protocol:

First, you MUST stop the moisture source. The AC leak needs to be professionally repaired by a certified HVAC technician. No mold remediation will succeed if the water intrusion continues. This is non-negotiable.

For the mold itself: The concrete slab is porous, meaning the mold roots (hyphae) have penetrated deep into the material. Surface cleaning will not remove it. The affected section of carpet and underlay must be removed and properly disposed of. The concrete then requires abrasive cleaning (e.g., sanding or media blasting) to physically remove the contaminated material, followed by an application of an EPA-approved antimicrobial sealant to kill any remaining spores and prevent regrowth. DIY bleach or vinegar can actually worsen the situation by adding moisture.

Given the hidden nature of the mold and the potential for it to have spread within the AC system or wall cavities, a professional inspection is strongly advised. We use thermal imaging and moisture meters to assess the full extent of the damage, which is often far greater than what's visible.

For a proper assessment and a guarantee that the mold won't return, call our specialists at 800-MOLDS (800-66537) or email hello@saniservice.com. We can provide a detailed remediation plan that complies with Dubai Municipality's strict health and safety standards for indoor environments.
