How to quickly fix AC leak and black wall mold?« Back to Previous Page

The AC in our apartment in Jumeirah Village Circle has been leaking a little, and now we've got these black splotches appearing on the wall behind the bedroom wardrobe. I only noticed it when I moved the furniture to clean yesterday. What's the fastest way to deal with this before it gets worse in this humidity?

Based on your description, you are dealing with a classic case of condensation-induced mold growth, a very common issue in Dubai due to our high humidity and year-round AC use. The black splotches are almost certainly mold, and the AC leak is providing the constant moisture source it needs to thrive.

The fastest and most effective way to address this is a two-step process: eliminate the source, then remediate the result. First, you must stop the AC leak. This is not a DIY fix; you need a certified HVAC technician to diagnose and repair the issue, which is likely a clogged condensate drain line or a faulty drain pan. Merely wiping the wall will achieve nothing if the leak continues.

Second, the mold growth must be professionally assessed. The location behind the wardrobe suggests it may be more extensive than visible. Disturbing it improperly can release spores throughout your apartment. For a confirmed case like this, professional inspection and remediation are strongly recommended to ensure it is removed safely and completely, in line with Dubai Municipality's public health and safety guidelines.

For immediate action, I advise you to call a professional team. Our company, Saniservice, specializes in exactly this scenario. We can coordinate the HVAC repair and perform the necessary mold testing, containment, and hygienization to ensure your bedroom is safe and the problem does not recur. Do not delay, as the humid climate will cause it to spread rapidly.
