Before anyone goes on your roof

What should you ask a chimney company in Ohio?

  1. Is your company a member of the National Chimney Sweep Guild (NCSG)?
  2. Does the technician coming to my home hold an individual NCSG certification, and which one?
  3. Does the technician hold a National Fireplace Institute (NFI) certification — and for which fuel: wood, gas, or pellet?
  4. What other certifications does the technician hold (for example, CSIA), and can I check them on the issuer's own roster?
  5. What state or local license or registration covers this work here, and what is the number?
  6. Will you send a certificate of insurance, dated and naming your company, before work starts?
  7. Which NFPA 211 inspection level — Level 1, 2, or 3 — are you performing, and why that level?
  8. Will you show me what you found — photos or video of the flue — in writing?

We take no fee from any certification body, guild, or contractor, and are not paid to mention anyone named.
