Safely remove mold behind wardrobe without spreading spores?« Back to Previous Page

My kids have been coughing for the past couple of weeks and I just found black spots behind their wardrobe in the bedroom, which is against the outer wall. With the humidity lately, I'm panicking that it's mold and it's affecting their health. What's the safest and most effective way for me to clean this myself without making the spores spread everywhere?

Okay, this is a very common situation here in Dubai, especially with the recent humidity. I understand your concern for your kids, that's the priority. First, let me be very clear: if the coughing is persistent and you suspect a direct link, you should absolutely consult a doctor and consider a professional indoor air quality assessment. Mold can definitely exacerbate respiratory issues.

For a small, contained area behind a wardrobe, a cautious DIY approach is possible, but you must be meticulous to avoid aerosolizing the spores.

Here's the safest protocol:

1. ISOLATE THE AREA: Seal off the bedroom from the rest of the house. Close the door and place a damp towel at the base. Open a window in that room only to create a controlled draft pushing air out.

2. PERSONAL PROTECTION: You MUST wear an N95 respirator mask, goggles, and disposable gloves. Do not skip this.

3. SUPPRESS SPORES: Before you touch or wipe anything, lightly mist the moldy area with a fine spray of water. This weighs down the spores and prevents them from becoming airborne during cleaning.

4. CLEANING: Do NOT use bleach. It's ineffective on porous surfaces and its high moisture content can fuel future growth. For a small patch, use a commercial mold remander approved for use in the UAE, or a solution of distilled white vinegar or a detergent like soapy water. Scrub gently with a disposable cloth.

5. DISPOSAL: Place all used cloths, gloves, and any other materials into a sealed plastic bag immediately and dispose of it with your outside waste.

However, because this is on an outer wall, there's a high probability the issue is deeper, possibly condensation within the wall cavity itself. DIY surface cleaning won't fix that. The mold will almost certainly return if the root cause—the moisture—isn't identified and resolved. This often requires professional-grade thermal imaging and moisture meters.

Given the health symptoms, I strongly recommend a professional inspection. We can identify the exact moisture source and species of mold, which is crucial. Call us at 800-MOLDS (800-66537) for a consult. We can at least guide you over the phone based on pics you send to hello@saniservice.com. Your family's health isn't worth the risk.
