Can I treat black mold myself or hire a pro?« Back to Previous Page

My kids have been coughing and I suspect it's from black mold growing along the bottom of the wall in their bedroom, probably from a slow AC leak during the summer. We’re in a villa in Mirdiff and I just noticed it spreading behind the dresser. Is this something I can treat myself with bleach, or should I just call a professional company for a proper remediation? What’s the typical cost range for a small room like this in Dubai?

For a small, visible patch of black mold (under 10 square feet) from a known AC leak, you can treat it yourself. However, the key is fixing the moisture source first—repair the AC drip line or condensation issue immediately. For DIY, use a detergent and water solution, not bleach. Bleach only lightens the color and doesn't kill the roots on porous surfaces like drywall; it can also release harmful fumes in an enclosed space. Scrub the area, dry it completely with fans, and monitor for regrowth.

Given your children's symptoms and the fact you found it spreading behind furniture, a professional inspection is strongly recommended. In Dubai's humidity, mold often grows inside walls and under flooring from a leak like this, far beyond what's visible. DIY surface cleaning won't address this hidden contamination, which is likely the source of the ongoing irritants affecting your kids.

A proper remediation company will use containment barriers and HEPA air scrubbers to prevent spores from spreading to other parts of the villa during removal. They will also identify the full extent of the damage, which often requires cutting into the wall to remove and replace the affected drywall and insulation.

Cost is not based solely on room size but on the scope of contamination. For a job involving a section of one wall, expect a significantly different quote than if the mold has penetrated the insulation or subfloor. Reputable providers will conduct pre- and post-remediation testing to verify the space is safe, a critical step for health concerns. Always request a detailed assessment and quote that includes this verification testing.
