Inspection service guide
Level 1, Level 2 and Level 3 Chimney Inspections
A plain-language guide to the three inspection levels described by NFPA 211 and how to clarify the proposed scope.
What the service involves
Start with a defined scope
NFPA 211 describes inspection levels with different access and examination requirements. A Level 1 is generally associated with continued use under unchanged conditions; Level 2 involves additional accessible areas and internal surfaces in circumstances such as changes or property transfer; Level 3 may include access to concealed areas when needed to investigate a suspected hazard. The applicable edition and locally adopted requirements should be confirmed by the professional.
Routine maintenance, condition assessment and repair are separate scopes even when one company can perform more than one. Ask the professional to distinguish what is included today from work that would require a separate authorization.

Inspection levels questions
Does every chimney sweep company provide inspection levels?
No. Company scopes, equipment and qualifications vary. Confirm the exact service, technician experience and service area before booking.
How should I compare proposals for inspection levels?
Give each provider the same property details and requested outcome. Compare observations, included work, access, materials, documentation, exclusions, price basis and warranty.
Can this page tell me what my chimney needs?
No. This is general preparation guidance. A qualified professional must assess the appliance and chimney on site.
