The investigative procedure generally consists of the following:

  • Develop understanding of problem and history
  • General walk around and then focused investigation
  • Obtain information on all building materials and code requirements in area of loss (i.e., type of materials, age, type of insulation, type of HVAC system)
  • Building science and HVAC specialties
  • Document environmental conditions within structure
  • Perform moisture mapping and document fungal patterns
  • Conduct environmental sampling
  • Develop sketch of building footprint and document all evidence discovered
  • Eliminate sources of causes of fungal conditions
  • Connect the dots and develop a firm understanding of the Origin and Cause
