We can check for dangerous and potentially lethal gases like carbon monoxide (CO). This is not to be confused with carbon dioxide (CO2), which for the purposes of IAQ helps us to determine if there is sufficient air change in the areas monitored.

Our moisture meter is non-intrusive and helps to determine if there is excessive moisture inside walls that could foster mold growth.
  • Surface samples are taken using sterile swabs or tape lifts mounted on microscope slides.
  • Tape lifts can be analyzed for mold or dust composition.
  • Air samples are taken using Air-O-Cell cassettes and can be taken from ambient air or from wall or ceiling cavities.
  • Dust samples from carpets are taken using a different kind of cassette and can be analyzed for fungi and bacteria.
  • We also use a cutting edge technology whereby we take a settled dust sample that is analyzed on the site for molds most commonly found in water damaged building materials. This methodology can detect if there has been a history of mold contamination.
