Professional mold remediation cost for wall: DIY or pro?« Back to Previous Page

Hey there, that’s a super common issue we see here in Dubai Marina, especially with the recent humidity spike. What you're describing with the black speckles is almost certainly a mold colony, and wiping it with vinegar is one of the worst things you can do. It just disturbs the spores and spreads them, plus the moisture from the wipe feeds it. Not good.

For a wall behind a sofa, you're likely looking at a localized infestation. A professional remediation for a spot that size here in the UAE typically ranges from AED 1,500 to AED 3,500. The cost depends on the extent of moisture damage behind the surface and if the drywall needs replacement. This might seem high, but a pro job includes containment to prevent cross-contamination, industrial-grade HEPA filtration, and antimicrobial treatment to stop regrowth—something DIY kits from Ace Hardware can't do.

Honestly, skip the DIY on this. You risk your health by exposing yourself to allergens and mycotoxins, and if you don't fix the underlying moisture issue (which is probably condensation from that exterior wall), it will come back, potentially causing structural damage that you could be liable for with your landlord.

Your best move is to get a certified inspection. They’ll use moisture meters and thermal cameras to find the source and give you a precise quote. For a definitive answer and to get it done right, just call 800-MOLDS or email hello@saniservice.com for a proper assessment.
