AC leak causing mold and sickness: professional help needed?« Back to Previous Page

Yes, this requires professional assessment and remediation. The combination of visible mould, an active water source from the AC leak, and correlating health symptoms means it has likely spread inside the wall cavity where you cannot see it.

In Dubai's high humidity, mould can colonize drywall and insulation rapidly, often within 48-72 hours of a leak. The black spots on the wall are just the visible tip of the problem. Your husband's morning headaches and congestion are common reactions to the volatile organic compounds (VOCs) released by actively growing mould colonies.

Do not attempt to clean this yourself. Disturbing it with bleach or DIY sprays can aerosolize spores and make the health issues worse. The first step is to stop the source: shut off the AC unit and call an HVAC technician to repair the leak immediately.

For the mould, you need a professional inspection. They will use moisture meters and borescopes to assess the wall's internal damage. Reputable remediators follow IICRC standards, which include containment barriers and HEPA filtration to prevent cross-contamination during removal. The wall section and affected carpet padding will likely need to be removed and replaced.

Since health is already impacted, ask the inspection company if they can provide post-remediation verification testing to confirm the spore count in the room has returned to a normal baseline. This is the only way to be sure the environment is truly healthy for sleep again.
