The inspection level is not a score or an upgrade package. It describes how much of the chimney system must be examined based on the reason for the inspection, the system history and any recent changes.
What a Level 1 inspection covers
A Level 1 inspection is intended for a chimney that will continue under the same conditions of use. The connected appliance, fuel and venting arrangement have not changed, and there is no known event that calls for a more detailed investigation.
The technician examines readily accessible portions of the chimney, fireplace or appliance connection and termination. If deposits prevent a useful view, cleaning may be recommended before the condition can be evaluated.
- Routine annual inspection of an unchanged system
- Accessible firebox, damper, connector, flue and exterior observations
- Visible maintenance concerns and repair recommendations
When a Level 2 inspection is appropriate
A Level 2 inspection adds accessible areas such as attics, crawlspaces and basements and uses video scanning when needed to observe the internal surfaces of the flue liner. It is commonly indicated when the system or the circumstances have changed.
Typical triggers include a property sale or transfer, a new appliance or fuel type, relining work, a suspected chimney fire or another event that may have damaged the system.
- Buying or selling a home
- Changing an appliance, fuel, input rating or venting arrangement
- Suspected chimney fire, severe weather damage or impact
- A Level 1 finding that cannot be resolved without closer examination
What the camera can reveal
A flue scan can document cracked clay tiles, missing mortar joints, offsets, gaps, deteriorated surfaces, deposits and obstructions that are not visible from the fireplace opening. It also helps the technician explain the location and extent of a defect instead of relying on a general description.
A camera does not make every concealed area accessible. The report should identify limitations when a roof, attic, chase or connection cannot be reached without destructive work.
Which inspection should you schedule?
For routine annual service with no changes or known events, start with a Level 1 inspection. For a real-estate transaction, appliance change, suspected fire or liner concern, discuss a Level 2 inspection before the appointment so the correct equipment and time are reserved.
What to remember
- Level 1 is for routine review of an unchanged system.
- Level 2 adds expanded accessible areas and internal flue scanning when indicated.
- A property transfer or major system change commonly calls for Level 2.
