AC leak causing black mold: need professional treatment cost?« Back to Previous Page

Yes, you need a professional assessment and treatment. The black spots and damp smell indicate active mold growth, which is a common issue in Dubai due to our high humidity and constant AC use. The leak provides the moisture mold needs to thrive, and wiping it with vinegar only addresses the surface, not the root cause or the spores embedded in the porous wall material.

For a situation like this in an apartment, your first step should be to notify your building management or landlord. Dubai Municipality regulations often hold the property owner responsible for maintaining the structural integrity of the building, including fixing AC condensate drain line leaks which are a frequent culprit. They need to send a technician to repair the leak immediately; without stopping the water source, any mold treatment will fail.

Once the leak is fixed, a professional mold inspection is crucial. They will assess the extent of the spread, which can be hidden inside the closet wall or under flooring. Proper remediation involves containment to prevent spores from spreading, removal of contaminated porous materials like drywall, and HEPA vacuuming and antimicrobial treatment of the area. The cost for remediation is not fixed; it depends entirely on the square footage affected and whether demolition is required. For a small closet area, it may be a localized project, but if the moisture has seeped into the adjacent wall, the scope increases. You should request assessments from certified providers who can give you a detailed scope of work and quote after an on-site inspection. Always verify that their proposed solution includes fixing the water source first.
