Black mold in bedroom: DIY removal or hire professional?« Back to Previous Page

That patch is a common issue in Dubai villas, especially in rooms with exterior walls where cool AC meets humid air, creating condensation. The risk depends on the mold type and size of the infestation.

For a small patch (under one square meter), a thorough DIY approach can work. Use a vinegar or hydrogen peroxide solution, not bleach, as bleach only removes surface discoloration and does not kill the root structure. Scrub the area, let it dry completely, and address the moisture source—often poor ventilation or a thermal bridge in the wall.

For a "huge patch" behind a wardrobe, professional remediation is strongly advised. The mold has likely penetrated the wallboard or plaster, and disturbing it without proper containment can spread spores throughout your home. Professionals use HEPA filtration, antimicrobial treatments, and moisture meters to ensure the wall cavity is dry and the root cause is solved.

The cost for a single room is influenced by the extent of damage to the building materials. Expect a higher cost if drywall removal and replacement are necessary. Always request a detailed assessment and a scope of work that includes post-remediation verification to confirm the mold and moisture issue is resolved.
