How to dry and treat damp walls after Dubai storm?« Back to Previous Page

After the storm, our ground-floor apartment in Jumeirah still has damp patches on the lower part of the walls in the living room. It's been two weeks and the musty smell is getting worse, especially in the evenings. I'm worried about mold starting to grow behind the furniture. What's the most effective way to dry out these walls and treat them to prevent this from happening again with the next heavy rain?

Based on your description, this is a serious moisture intrusion issue that requires immediate and professional attention. The lingering dampness and musty odour, especially worsening in the evenings when temperatures drop, are classic indicators of active microbial growth, likely already established within the wall cavity. In Dubai's climate, with its high humidity, this process accelerates rapidly.

The most effective method is not simple surface drying. The gypsum-based plaster and concrete block construction common here acts like a sponge, wicking moisture upwards (capillary action). You must address both the residual moisture and the resulting microbial contamination. First, move all furniture away from the walls to allow for air circulation and proper inspection. Surface cleaning with bleach or vinegar is ineffective and can be hazardous; it only addresses surface discolouration, not the root cause embedded in the porous materials.

A professional remediation process involves several critical steps: using thermal imaging cameras and moisture meters to map the exact extent of the saturation, strategic removal of baseboards and possibly sections of damaged drywall/plaster to expose the cavity, and employing industrial-grade dehumidifiers (like desiccant models) and high-velocity air movers in a contained environment to achieve rapid and complete drying. This is followed by the application of EPA-approved antimicrobial agents to treat all affected structural surfaces, preventing regrowth. Finally, any removed materials are replaced with moisture-resistant alternatives where applicable.

Given the time elapsed and the symptoms, a DIY approach risks significant structural damage and health impacts from poor indoor air quality. This is a job for certified technicians. We strongly recommend a comprehensive inspection to assess the hidden damage and create a targeted remediation plan.
