How to permanently stop closet mold and damp smell?« Back to Previous Page

Our master bedroom closet, which is on the outside wall of our villa in Mirdif, has started to get a really strong damp smell, especially on the cooler mornings. I pulled out some winter clothes I stored and found small black spots on a couple of leather bags. We run the AC constantly, but it seems like the humidity is still getting trapped in that enclosed space. What’s the most effective way to treat this and prevent the mold from coming back for good?

Based on your description, this is a classic case of interstitial condensation, very common in Mirdif villas due to the high humidity differential between our cool AC interiors and the hot exterior walls. The closet on an outside wall is a prime location for this. The small black spots are almost certainly active mold growth.

First, stop the moisture source. Simply running the AC isn't enough; it needs to be the right type and set correctly. Ensure you have a HVAC system with a powerful dehumidification function, not just cooling. Set it to maintain humidity below 55% RH. For the closet itself, you need to increase air circulation immediately. Leave the closet doors open and consider installing a small battery-operated dehumidifier or a passive moisture absorber like silica gel inside.

However, given the visible growth on your belongings, this has progressed beyond prevention. The mold needs to be professionally addressed. DIY cleaning with vinegar or bleach only addresses surface stains, not the root hyphae penetrating porous materials like leather and drywall. improper remediation can aerosolize spores, spreading the problem.

A certified inspector will use a thermal imaging camera to identify the exact cold spots and moisture meters to quantify the dampness within the wall, which is likely the core issue. Remediation involves controlled removal of affected materials, HEPA vacuuming, and application of EPA-approved antimicrobial coatings to prevent recurrence, all following DM and Dubai Municipality guidelines for environmental safety.

For a permanent solution, you need to identify and treat the source. Call us for a professional inspection at 800-MOLDS (800-66537) or email hello@saniservice.com. We can diagnose it properly and guarantee the remediation so your closet stays dry and odor-free for good.
