Understanding the Level 2 Chimney Inspection

A level 2 chimney Inspection is a detailed assessment of a chimney system that goes beyond the basic visual checks of level 1.

A level 2 includes inspection of all accessible portions of the chimney, including attics, crawl spaces, and basements, as well as a video scan of the flue interior. This comprehensive evaluation documents the condition of the chimney liner, checks for blockages, and identifies hidden structural defects that could lead to fire or performance issues.

A level 2 chimney Inspection is a detailed evaluation of a chimney system from the NFPA 211. It is required when:

There’s a change in the system: installation of a new appliance (stove, insert, or fireplace), change in fuel type, or flue relining.
Property sale or transfer: real estate transactions demand a thorough safety and usability assessment.
System malfunction or known damage: chimney fire, weather event, or operational issues warrant this inspection.

The inspection involves all accessible portions of the chimney exterior and interior, including attics, crawl spaces, and basements. It requires a video scan or equivalent of the flue interior to document its condition.

When Do You Need a Level 2 Chimney Inspection?

1. Change in the Chimney or Venting System
A Level 2 Chimney Inspection is essential any time there’s a modification to your fireplace or stove setup. This includes installing a new appliance, converting fuel types (e.g., from wood to gas), or altering the flue with a liner or structural changes. These adjustments can impact draft performance, clearances to combustibles, and overall system safety. NFPA 211 requires this inspection to verify compatibility and ensure the chimney can safely handle the new operating conditions.

2. Property Sale or Real Estate Transfer
When buying or selling a home, a Level 2 Chimney Inspection provides a comprehensive assessment of the chimney’s condition and code compliance. Unlike a general home inspection, this specialized service includes an interior flue scan and inspection of concealed spaces such as attics and crawl spaces. For real estate professionals and home buyers, this inspection delivers peace of mind and negotiation power by uncovering hidden defects, such as creosote buildup, liner damage, or structural deterioration.

3. After a Chimney Fire, Weather Event, or Operational Concern
A Level 2 Inspection is mandatory if a chimney has been exposed to events that could compromise its structural or functional integrity. This includes chimney fires, lightning strikes, seismic activity, or high winds that may shift masonry or damage components. Even absent visible damage, internal deterioration or blockage may occur. Operational issues like smoke spillage or draft failure are also key indicators. This inspection includes a video scan of the flue to identify cracks, voids, or creosote glaze layers that pose serious risks.
