Mold testing in Oregon
Western Oregon's wet winters and persistent dampness make indoor moisture, condensation and attic mold frequent issues.
When Oregon homeowners should consider testing
- After a flood, storm, roof leak or plumbing leak
- Persistent musty odor with no visible source
- Buying or selling a home, especially one with a crawl space or basement
- Unexplained allergy-like symptoms at home
- Confirming remediation is complete
Choosing an inspector in Oregon
Ask for proof of insurance, a sample report, which accredited lab they use, and whether they also sell remediation (independent testers avoid a conflict of interest).
