AC mold causing toddler's cough: DIY clean or call pro?« Back to Previous Page

Given the leak and your toddler's recurring symptoms, this requires professional remediation. The combination of a persistent water source and visible growth indicates a deeper issue that DIY cleaning cannot address. Surface cleaning with bleach or vinegar will only temporarily remove the visible stain, while the mould's root structure (mycelium) remains active inside the wall, continuing to release spores into the bedroom air your child breathes all night.

In Dubai's climate, AC units constantly combat high humidity, making them a primary source of condensation and subsequent mould growth if not perfectly maintained. The leak has created an ideal, damp environment inside your wall cavity. A proper remediation involves first fixing the AC leak at its source, then using containment procedures like negative air pressure to prevent spores from spreading to other parts of the home during the cleanup. The affected section of drywall likely needs to be safely removed and replaced.

For a case involving a vulnerable occupant like a young child, a professional inspection is strongly advised. They can perform air and surface sampling to identify the mould species and confirm the spore count in the room has returned to a safe level post-remediation. This provides peace of mind that the environment is truly healthy. Until it's handled, try to improve ventilation in the room and keep your toddler out of it as much as possible.
