How to remove and prevent mold making my family sick?« Back to Previous Page

The damp wall and family cough are classic signs of a mold issue that needs immediate attention. For your situation, the most effective approach is a multi-step process: identify the moisture source, safely remove the contaminated materials, and implement lasting prevention.

First, stop the moisture. In Dubai, the wall facing outside is a common trouble spot due to intense sun heating the exterior, which then cools rapidly from your indoor AC, causing significant condensation inside the wall cavity. This hidden dampness is the root cause. A professional inspection with a thermal imaging camera can pinpoint the exact condensation points and rule out a hidden pipe leak.

For removal, any visible mold on porous materials like drywall or the back of the wardrobe likely requires cutting out and disposing of the affected section. Simply wiping or spraying it is insufficient, as the fungal roots (hyphae) penetrate deep. This containment and removal should be done by a certified remediation team to prevent spreading spores throughout your home, which could worsen your family's exposure and symptoms.

To ensure it doesn't return, the cavity must be treated with an antimicrobial coating after the wet materials are removed and the area is completely dry. Then, address the condensation. This often involves improving wall insulation and, crucially, ensuring your AC is not set too cold, which creates a larger temperature differential with the outside heat. Maintaining indoor humidity below 60% with a dehumidifier, especially during humid months, is critical for prevention.

Given the health symptoms, a post-remediation verification test from an independent lab is highly recommended to confirm the spore count in the air has returned to a safe level before the wall is rebuilt.
