Certification is not a generic label
Different organizations administer different credentials. Ask for the exact credential name instead of relying on the word “certified.”
The individual matters
Verify the person who holds the credential. Do not assume every employee of a company holds every credential displayed in its marketing.
Different credentials test different knowledge
CSIA describes its Certified Chimney Sweep credential around chimney and venting evaluation and maintenance. NFI describes its certifications around hearth planning, installation and venting. Specialized education can complement foundational credentials.
Verification is simple
Use the credential issuer’s official public directory whenever one is available. VerifySweep’s goal is to make those checks easier for homeowners.
Verify from the source.
Use official credential and policy sources whenever possible.
