Every company on record in St. Clair County

Ordered by verification score. The score counts records rather than workmanship, and the license line says which of three things is true: verified against the roster, checked and not found on it, or not yet checked at all.

The license check in Illinois

No public septic license roster is published for Illinois that we can check a company against, so license status for every company in St. Clair County reads as unverified. That is a gap in the public record, not a mark against any company.
