How to quickly remove mold from AC leak?« Back to Previous Page

My kids have been coughing non-stop for the past two weeks and we can't figure out why. I finally pulled out the sofa in our Deira apartment to look behind it and found a huge patch of black mold spreading up the wall, probably from a slow AC leak we never noticed. I'm really worried their health is being affected by this. What is the fastest and most effective way to get this professionally removed and make sure it doesn't come back?

First, address the source of moisture immediately. Turn off the AC unit servicing that area and have an HVAC technician repair the leak. Without fixing the water source, any mold removal is temporary.

For a patch of significant size, especially with health symptoms present, professional remediation is strongly advised. In Dubai's high humidity, DIY attempts often spread spores or leave mold deep within walls. Professionals will contain the area with physical barriers, use HEPA-filtered negative air machines to prevent cross-contamination, and safely remove all affected materials. They should then treat the area with antimicrobial solutions and use industrial-grade dehumidifiers and air scrubbers to dry the structure completely.

After remediation, a third-party, independent post-clearance test is critical. This verifies spore counts inside the contained area have returned to ambient outdoor levels, confirming the job was done correctly. This is a standard best practice in the UAE for peace of mind.

To prevent recurrence, ensure the AC leak is fully repaired and consider a dehumidifier for that room. Regular AC maintenance is essential, as units here run year-round and condensation issues are common. For your children's ongoing cough, a consultation with a pediatrician is recommended to address any lingering irritation.
