We use thermal imaging cameras that detect temperature differentials indicating moisture intrusion. When we scan your walls, cold spots appear where water has saturated insulation or drywall. These thermal signatures reveal detecting hidden mold before visible staining occurs.
Moisture meters give us exact readings at various depths within building materials. We probe wall cavities, subflooring, and ceiling assemblies to map moisture gradients. Readings above 16 percent in wood or 1 percent in drywall indicate conditions supporting mold colonization.
Our borescope cameras fit through quarter-inch holes drilled in inconspicuous locations. We snake these inspection cameras into wall cavities, above drop ceilings, and into HVAC plenums to visually confirm symptoms of concealed mold without destructive demolition.
Air sampling captures spore counts in your indoor environment and compares them to outdoor baseline levels. Elevated counts of specific mold genera like Stachybotrys, Chaetomium, or Aspergillus indicate active growth even when no visible colonies exist.
We test HVAC systems separately because air handlers often harbor indicators of invisible mold on evaporator coils and in condensate pans. Chicago's humidity keeps these components damp for extended periods, creating perfect growth conditions that spread spores throughout your ductwork.
Surface sampling with tape lifts and swabs confirms species identification. Lab analysis determines whether you have allergenic, pathogenic, or toxigenic mold strains. This information guides remediation protocols and helps your physician understand your exposure risk.
Every investigation generates a detailed moisture map showing exactly where evidence of unseen mold exists within your property structure. This documentation supports insurance claims and provides contractors with clear scope boundaries for remediation work.
