What to look for
A homeowner should separate marketing signals from qualification signals. Reviews, ads and search position can be useful context, while independently verifiable credentials provide a different kind of information about education and testing.
What to document
Before hiring, identify the technician when possible and verify relevant credentials directly with the issuing organization. CSIA maintains a public credential directory, and NFI provides a public specialist search.
How to use it
Use Google to find candidates. Then verify the professional, compare documentation, ask questions and make the hiring decision based on more than visibility alone.
Independent sources
Credential and platform-policy claims should be checked against the issuing organization or platform. VerifySweep encourages direct verification rather than relying on a logo, advertisement or third-party claim.
