Cost to remove mold behind wardrobe or DIY with bleach?« Back to Previous Page

Cost for a project like this depends on the extent of the mold growth behind the wall and whether the source of moisture has been resolved. Small, surface-level patches are less expensive, while remediation requiring wall removal to address the root cause and treat the cavity is more involved. For an accurate estimate, a professional assessment is needed to determine the moisture source and scope.

Using bleach is a complete DIY fail for porous surfaces like drywall and plaster. It only bleaches the visible colour on the surface while the organism's structure remains deep within the material. More critically, the water in bleach solution can actually feed the mold, causing it to regrow more extensively inside the wall. This approach often makes the problem worse and more expensive to fix later.

Given the Jumeirah location and recent humidity spike, the moisture source is likely condensation from your air conditioning system or a minor, hidden plumbing leak—both common in Dubai's climate. A professional inspection will use moisture meters and thermal imaging to find the exact cause, which must be fixed before any remediation begins. Otherwise, the mold will return regardless of the cleaning method.

For health reasons, especially with existing allergies, professional remediation is strongly advised. Proper protocols involve containment to prevent spores from spreading to other parts of the house during removal, HEPA vacuuming, and antimicrobial treatment of the affected area. They will also verify the fix with post-remediation testing to ensure the space is truly healthy. Attempting this yourself risks inadequate removal and significant cross-contamination.
