How to check for and prevent hidden mold in Dubai?« Back to Previous Page

My kids have been coughing for a couple of weeks now, and I’m starting to worry it’s more than just a bug going around. We live in a villa in Jumeirah, and I’ve noticed a faint damp smell coming from the guest room’s walk-in closet, which is on an exterior wall. It’s been especially humid since the last rainfall, and I’m terrified there’s hidden mold growing behind the shelves. What’s the most effective way for a homeowner here in Dubai to check for hidden mold in a closet like this without tearing down the walls, and what steps should we take to prevent it from coming back in our climate?

Good question. This is a very common issue in Dubai villas, especially after the recent humidity and rain. The symptoms you describe, particularly the persistent cough and that tell-tale damp smell, are significant red flags for hidden mold. Here's what I recommend.

First, do not tear down the walls. A visual inspection is your first step. Pull everything out of the closet. Use a high-powered flashlight to look for any visible discoloration, water staining, or fuzzy growth on walls, baseboards, and the back of the shelves. Check for any warping or softening of the drywall or wood—poke it gently with a screwdriver; if it's soft, moisture is present.

For a more advanced check without demolition, you can rent a borescope from a hardware store. This is a small camera on a flexible cable that can be fed through a tiny, easily repairable hole to see inside the wall cavity. However, the most definitive method is professional testing. We use moisture meters to detect elevated moisture levels within walls and perform air and surface sampling to identify the specific mold spore types and concentrations. This is crucial for understanding the health risk and planning remediation, especially with kids involved.

Prevention is all about controlling humidity, which is a battle here. Ensure your AC is serviced and draining properly; a clogged drain line is a prime cause. Use a dehumidifier in that room, especially during humid periods. Improve air circulation—don't overcrowd the closet and leave the door ajar occasionally. Crucially, inspect that exterior wall for any cracks in the rendering or sealant that could be letting moisture in during our occasional rains.

Given the symptoms and location, this isn't something to DIY. Hidden mold needs to be properly assessed and contained during removal to prevent spreading spores throughout your home. For a thorough inspection and a clear plan, it's best to call in a certified professional.
