How to permanently remove hidden mold in damp bedroom?« Back to Previous Page

Based on your description of the runny nose, cough, and the damp external wall facing the marina, you are almost certainly dealing with a hidden mold issue, which is very common here in Dubai due to the high humidity and thermal bridging in building envelopes.

First, do not attempt to clean the visible spots yourself. Disturbing it will release a massive amount of spores, potentially worsening your family's health issues. The spots behind the wardrobe are just the visible tip of the iceberg; the hidden colony within the wall cavity is the real problem.

The only permanent solution is a professional remediation protocol. Here’s what we would do:

1. Inspection & Testing: A certified inspector uses moisture meters, thermal imaging cameras, and air sampling to map the full extent of the contamination behind the wall and assess spore levels in your bedroom air. This is crucial for a permanent fix.

2. Containment: The area must be sealed with plastic sheeting to create negative air pressure, preventing cross-contamination to the rest of your apartment during the work.

3. Removal & Treatment: The affected section of drywall is carefully removed. The wall cavity and structure are then HEPA-vacuumed and treated with specialized antimicrobial agents to kill the root colony, not just surface mold.

4. Address the Source: This is the critical step. The dampness is likely due to condensate formation on the cold surface of the external wall (thermal bridging). We would recommend professional assessment for adding insulation or a vapor barrier to prevent this from recurring endlessly.

Given your children's symptoms, this is a serious indoor air quality issue. A DIY approach will fail and likely make it worse. You need a certified professional assessment to solve this for good.
