How to remove black mold in closet or call pro?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black mold in the corner of our master bedroom closet. It's on the wall that faces the outside, and with all the humidity we've had lately, it seems to be spreading. I'm really worried about our health and damaging our clothes. What's the best way to handle this myself, and when should I definitely call a professional?

As a certified mold remediation specialist operating in Dubai, your situation is unfortunately very common due to our high humidity levels and year-round AC use, which can create significant condensation on cold exterior walls.

For a small patch (less than 1 square meter), you can attempt a DIY clean. First, ensure personal protection with an N95 mask and gloves. A solution of distilled white vinegar or a diluted bleach mixture (1 part bleach to 10 parts water) can be effective. Scrub the area thoroughly, ensuring you address the root cause by improving ventilation in the closet and wiping down the exterior wall for condensation regularly. However, simply cleaning the surface is often a temporary fix.

Given that the mold is on an exterior wall and spreading, I strongly recommend a professional inspection. This indicates a persistent moisture issue, likely from condensation within the wall cavity or a minor leak, which is beyond a surface clean. In the UAE, professional remediation companies like ours follow strict guidelines for containment and removal to prevent cross-contamination. We use specialized equipment like HEPA vacuums and air scrubbers to ensure spores are not dispersed throughout your home, protecting your health and belongings.

For a proper assessment and to avoid potential health risks or property damage, it is best to call a professional. Contact Saniservice at 800-MOLDS (800-66537) or hello@saniservice.com for a comprehensive inspection and a guaranteed remediation plan.
