Mold in bedroom closet: DIY or pro treatment cost in Dubai?« Back to Previous Page

This is a common issue in Dubai, especially on exterior walls where temperature differences cause condensation, creating a perfect environment for mold. That black fuzzy patch is a colony actively releasing spores, which can cause respiratory irritation, worsened allergies, and persistent musty odours.

For a small, visible patch, a careful DIY approach can work. Use a solution of white vinegar or a dedicated mold cleaner, not bleach. Bleach only removes the surface colour and does not kill the roots penetrating porous materials like drywall. Scrub gently to avoid aerosolizing spores, wear an N95 mask and gloves, and ensure the area is well-ventilated.

However, given its location on an exterior wall, the moisture source is likely condensation from thermal bridging, which is a building envelope issue. DIY cleaning will only be a temporary fix if the underlying humidity problem isn't solved. The mold may also have spread behind the wall.

Professional remediation is recommended when the area is larger than one square meter, if there's a persistent moisture source, or if occupants have health sensitivities. A proper assessment involves moisture meters and thermal imaging to find the extent of the problem. Reputable companies will then contain the area, remove contaminated porous materials like drywall, HEPA-vacuum all surfaces, and treat the area with EPA-approved antimicrobials, not just a surface spray. The final, critical step is identifying and rectifying the moisture source to prevent recurrence.

Cost is not fixed; it depends entirely on the extent of the hidden damage. A small, contained job is significantly less than one requiring wall removal and reconstruction. Always request a detailed, on-site inspection and a scope of work that includes addressing the root cause, not just the visible mold.
