1. Who holds the credential?
Ask for the name of the individual credential holder, not only whether the company displays a certification logo.
2. Is it current?
Use the issuing organization’s official directory or verification method when available.
3. What does it cover?
A chimney certification, hearth-fuel certification, inspection credential, manufacturer course and trade-association membership are not interchangeable.
4. Will that person perform or supervise my work?
A company may employ a credentialed professional without every employee holding the same credential.
5. What else supports the recommendation?
For significant repairs, ask for inspection findings, photos, measurements, applicable manufacturer instructions and a clear written scope.
VerifySweep standard: Evidence should support the exact statement being made. A suspicious indicator is a reason to investigate, not a verdict.
