How to check for hidden mold from AC leak?« Back to Previous Page

The constant dampness under your carpet pad from an AC leak is a significant concern in Dubai's climate, as it creates an ideal environment for mold growth within 24-48 hours. The high humidity year-round accelerates this process.

For a verifiable check, start by feeling the carpet and pad for persistent dampness or a spongy texture. A musty, earthy odour is a strong indicator of hidden microbial growth. Visually inspect the underside of the carpet and the subfloor if you can lift a corner or a section—look for discolouration, black speckling, or white fuzzy growth.

The most effective method is professional inspection. Technicians use moisture meters to quantify dampness in walls and floors and borescopes to see inside walls and under fixed carpets. For definitive identification, surface or air samples are analyzed by a microbiology lab to determine the species and concentration, which dictates the remediation approach.

To stop it for good, the AC leak must be fixed first—this is often a clogged condensate drain line, which is extremely common here due to dust. The damaged section of carpet pad must be removed and the subfloor thoroughly dried and treated. Simply drying the surface is insufficient, as the moisture is trapped underneath. For a confirmed mold issue, remediation follows strict DHA and DM guidelines to ensure it is properly contained and removed, preventing spores from spreading to other parts of your apartment.
