Urgent to hire mold removal pro or DIY with bleach?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots forming in the corner of our master bedroom closet where we store our winter clothes. It's on the wall that faces the outside of the building. With the humidity lately, I'm worried it's spreading quickly behind the clothes. How urgent is it that I get a professional mold removal company in here, or can I handle this myself with a bleach solution?

That wall is a classic trouble spot in Dubai. The exterior wall is likely colder from the AC, causing condensation to form behind your clothes, and the recent humidity provides the perfect fuel for mould. You need to act quickly.

For a small, visible patch (under one square meter), a thorough DIY approach can work. Bleach is not recommended; it’s mostly water and can feed mould roots inside porous drywall. Use a dedicated fungicidal cleaner or a solution of white vinegar and water. Scrub the area, let it dry completely, and address the moisture source by improving air circulation around that closet.

However, given its location on an exterior wall and the speed you’ve noticed, there is a high probability the mould has spread behind the surface. This is where DIY fails. A professional inspection, often involving moisture meters and borescopes, is needed to assess the wall cavity. Spores released during improper cleaning can also contaminate your HVAC system.

For this scenario, the urgency is high to prevent structural damage and potential health effects. The recommended step is a professional assessment to determine the full extent. Reputable remediators in the UAE follow strict protocols for containment and removal, ensuring the issue is resolved at its source, not just the surface.
