Mold 3. Decisions

Mold Hypothesis Testing in Buildings

Testing is sometimes useful to confirm suspicions gained from direct inspection.

Guess the answer

  • Form a cause/effect hypothesis: What is your best guess explanation for the moisture/mold problem? (moisture sources? pathways? driving forces?)
  • Do not form a hypothesis including health effects unless you have the expertise.
  • Decide what experiments and tests might confirm or deny the hypothesis.
  • Explain how any test results are consistent or inconsistent with the hypothesis.

Mold types

  • Surface molds (not wood rot) become airborne and affect our health.
  • The wettest conditions may grow worse types (but we worry about them all).
  • Some types grow mostly outdoors; their spores come indoors.
