shold I clean black mould myself or call a professional?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black mould in the corner of our master bedroom closet, which is on an interior wall. It seems to have gotten worse since the humidity kicked in a few weeks ago, and I'm worried it's spreading behind the clothes. Is this something I can safely clean with bleach myself, or do I need to call a professional mould inspection company to check for a bigger problem?

Discovering black mould in your closet is a common issue in Dubai, particularly during the humid summer months when condensation forms on cooler interior walls, often exacerbated by year-round AC use. While a small, surface-level patch might be addressed with a DIY approach, several factors specific to your case suggest a professional inspection is strongly recommended.

The primary concern is its location on an interior wall and the fact it has worsened, indicating a persistent moisture source. This is not simply surface condensation; the mould growth behind the clothes suggests a potential hidden problem within the wall cavity, such as a slow pipe leak or ingress from a faulty AC condensation drain line. Cleaning the visible patch with a bleach solution is inadvisable. Bleach only removes surface discoloration and does not kill the mould roots (hyphae) porous materials. More critically, improper cleaning can aerosolize harmful spores, spreading the contamination throughout your home.

In the UAE, proper remediation follows international IICRC standards. A certified professional from a company like Saniservice will conduct a thorough inspection using moisture meters and thermal imaging to identify the hidden moisture source—the key to preventing recurrence. They will then contain the area, safely remove contaminated materials, and use specialized HEPA filtration and EPA-approved antimicrobials to eradicate the colony at its root.

Given the potential for hidden spread and health risks, a professional assessment is the prudent course of action. For a comprehensive inspection and a definitive solution, I recommend contacting Saniservice. You can call them at 800-MOLDS (800-66537) or email hello@saniservice.com.
