Urgent: DIY mold removal or call professionals for leak?« Back to Previous Page

A leak from an AC unit in a Jumeirah villa is a high-priority issue due to Dubai's humidity. The black spots on your carpet and skirting board indicate active growth, and the wet backing and underlay are likely a larger reservoir you cannot see.

For a leak that's been present for two weeks, DIY with bleach is not recommended. Bleach only removes surface discoloration on porous materials like carpet and does not address the root moisture problem or the hyphae (roots) growing within the fibres. It can also release harmful fumes in an enclosed space.

The urgency is high. The continuous moisture from the AC drip, combined with our climate, creates an ideal environment for rapid mould expansion and potential secondary damage. Your first step is to stop the source: have an AC technician repair the leak immediately. Without this, any cleaning is pointless.

For assessment, a professional inspection is advised. They can use moisture meters to determine the extent of water saturation in the carpet, underlay, and potentially the subfloor. The remediation approach depends on this. A small, surface-level area on a hard surface might be cleanable, but wet carpet and padding often require removal and replacement to prevent ongoing microbial issues and structural damage. A company with its own microbiology lab can also take a swap to identify the species, which informs the correct remediation protocol.

In summary, call an AC technician to fix the leak today, then engage a professional inspector to assess the damage to the building materials before attempting any cleanup.
