Our verification notes

The Google rating/count is a web-visible third-party snapshot and can change. A municipal contractor-list entry was found, but its registration number was not reliably parsed, so stateLicense remains null. Type B water-control systems are not house elevation or dry floodproofing against river overflow.

Sources checked

  • BBB Business Profile (A+ accreditation, leadership, Cedar Rapids branch, services and tenure)
  • Quad Cities Chamber member listing (current contacts, principal and trade scope)
  • Quad Cities Builders & Remodelers Association listing (principal, email and service categories)
  • City of Sterling registered-contractor list (municipal general-contractor registration corroboration; number not exposed in snippet)
