Mold under carpet from AC leak: DIY or professional in Dubai?« Back to Previous Page

A professional inspection is strongly recommended for this situation. The black patch you see is likely just the surface growth; the real concern is the mould that has penetrated the carpet backing, underlay, and possibly the concrete slab underneath. In Dubai's climate, the constant humidity and condensation from an AC leak create a perfect environment for deep, hidden growth.

DIY bleach cleaning is ineffective on porous materials like carpet and can actually worsen the problem by adding moisture. Bleach only removes surface discolouration and does not address the root cause or the mycotoxins that some moulds produce. The AC leak must be repaired first; otherwise, the mould will return quickly.

For a patch that size, remediation typically requires cutting out and properly disposing of the affected carpet and underlay, then HEPA-vacuuming and treating the subfloor. The cost for professional remediation is variable, as it depends on the extent of the hidden damage and the materials affected. It is not typically a minor expense, but it is a necessary one for your health and to protect the property. The most budget-conscious approach is to get a detailed assessment and quote from a certified provider, which will outline the exact scope and cost.
