Indoor Air Quality/Mold Testing

Indoor Air Quality/Mold tests can tell you if you have hidden moisture or leaks that are producing spores that may represent a health risk to you and your family. These tests are provided as an appropriate response to concerns about poor air quality:

  • By occupants/residents
  • Before property transactions
  • After a catastrophic incident (flooding, storm, damage, water intrusion)
  • When new owners take over property


You should consider Indoor Air Quality/Mold Testing when:

  • Purchasing a home
  • A recent or past water event is suspected
  • A “musty” smell is noticed
  • An occupant of the home is predisposed to respiratory distress
  • Visible mold (or suspected mold) is present
  • Recent mold remediation took place and you want to verify the effectiveness

Air Sampling

  • The home inspector will first take an outdoor sample to serve as a baseline or control sample which will be compared to the inside samples.
  • Next, two samples will be taken inside the home, generally in the basement and near the attic (if applicable). If there is not a basement and/or attic, the inspector will determine the best location to take samples.

Surface Sampling

Our inspectors look for evidence of mold or “microbial” growth and if observed can take a surface sample by using a swab or tape to lift a sample of the growth. Both swabs and tape lifts are used to see if there is evidence of “current or former growth” due to water intrusion or excessive humidity causing the growth. Sometimes the dark or discolored “growth” is not microbial growth and therefore not evidence of water intrusion causing damage to your home. It is important to sample visible growth along with air samples to measure whether unwarranted exposure exists for you and your family.
