For a small area (under one square meter), you can attempt cleaning with a dedicated mold remover or a diluted vinegar solution, not bleach. Bleach only removes surface discoloration and does not kill the mold roots penetrating porous materials like drywall. You must wear an N95 mask, gloves, and eye protection during cleaning.

However, simply wiping the surface is a temporary fix. The dampness indicates the underlying cause is still active, and the mold will return. For interior walls with persistent dampness, a professional inspection is strongly recommended. They use moisture meters and thermal imaging to locate the source—whether it’s a leaking pipe, thermal bridging causing condensation, or rising damp. Without addressing this, the problem will recur.

Professional remediation is also advised if the area is large, if you smell a musty odor, or if household members experience respiratory issues. Reputable companies in the UAE follow international guidelines for containment and removal to prevent spores from spreading throughout your home during the cleaning process. The goal is to fix the moisture problem and verify with post-remediation testing that the environment has been returned to a healthy state.
