Weather considerations

Severe seasonal swings, basements vulnerable to spring rains, and a large stock of pre-1978 Chicago housing make basement mold the dominant complaint.

State licensing

Illinois 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
  • West Dundee's mix of older and newer homes means moisture issues range from crawl-space humidity to modern-build envelope condensation.
  • High regional humidity makes mold prevention a year-round concern, not just an after-a-leak fix.
