State licensing

Oregon does not have a state-level mold-license requirement. Verify each pro's industry certifications (IICRC, ACAC, etc.) and proof of insurance before hiring.

Local factors
  • Gresham's dense, mixed-age housing stock — including older multi-family buildings — can trap moisture behind walls and shared plumbing.
  • Very high regional humidity makes mold prevention a year-round concern, not just an after-a-leak fix.
