Black mold behind wardrobe: DIY or professional treatment cost?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots spreading on the wall behind the wardrobe in our master bedroom. It’s been super humid lately and I’m worried it’s making my allergies act up. Is this something I can tackle myself with bleach spray from the supermarket, or should I just call in a professional company to assess it? If I hire someone, what’s the typical price range for treating a small area like this in an apartment?

Based on your description of the situation, I strongly recommend against a DIY approach with supermarket bleach. The black spots spreading behind the wardrobe are a significant indicator of a persistent moisture issue, which is extremely common in Dubai due to our high humidity levels and constant air conditioning use, leading to condensation in poorly ventilated spaces. Bleach is a superficial solution; it may remove the visible discoloration on non-porous surfaces but it will not address the root moisture problem or effectively kill the mold hyphae (roots) penetrating porous materials like drywall and concrete.

In the UAE, improper mold remediation can inadvertently contaminate other areas of your home. A professional inspection is crucial to determine the extent of the infestation, identify the exact moisture source (often condensation from the AC system or a small leak), and perform proper remediation. This involves containment of the area, use of EPA-approved biocides, HEPA vacuuming, and antimicrobial coating to prevent recurrence. For a small area like behind a wardrobe, assessment and treatment costs for a certified company typically range from AED 1,500 to AED 3,500, depending on the severity and required containment procedures.

Given your allergy symptoms, this is not a project to handle yourself. For an accurate assessment and a lasting solution, I advise you to contact our team at Saniservice.
