How to test and treat black mold without being overcharged?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots spreading along the wall behind our bedroom wardrobe in Jumeirah. It’s the wall that faces the outside, and I’m worried it’s been there a while. What’s the best way to get this properly tested and treated without getting ripped off by a dodgy company?

Black mold growth behind furniture on an exterior wall is a common issue in Dubai, often caused by thermal bridging. The cold interior wall from AC use meets warm, humid outdoor air, creating condensation inside the wall cavity that you don't see until it spreads.

For proper testing, do not let any company that also does remediation perform the test—this is a conflict of interest. The most reliable method is to hire an independent indoor environmental professional to take a tape-lift or air sample, which is then analyzed by an accredited third-party microbiology lab. This identifies the species and guides the correct remediation protocol. In Dubai, look for a provider certified by a body like the IICRC or IAQA.

Treatment must address the source, not just the visible spots. A reputable company will first conduct a moisture survey to find the water intrusion point. Remediation involves isolating the area, removing contaminated porous materials like drywall, HEPA vacuuming, and antimicrobial treatment. They should provide a post-remediation verification report from an independent lab to confirm spore counts are back to normal indoor levels.

To avoid being overcharged, get three detailed assessments. Be wary of companies that quote a large price immediately without diagnostics or that promise to "eliminate" all mold. The goal is to return conditions to normal levels. Ask for their company certifications and a sample lab report to verify their process. Any reputable provider will be transparent with this documentation.
