Level 3 Chimney Inspection
A Level 3 inspection is the most thorough kind. It is used when a serious hazard is suspected and the answer cannot be reached without opening up part of the chimney or the building.
What makes it Level 3
NFPA 211 describes three inspection levels. Level 1 is a visual check of what is readily accessible. Level 2 adds the flue interior and the accessible parts of the building around the chimney. Level 3 includes everything in Level 2, and goes further: it can involve removing parts of the chimney or the building to reach concealed areas.
When it is called for
- A Level 2 inspection found a serious problem whose extent cannot be judged without opening the structure
- There are signs of hidden damage, such as heat damage near framing, that cannot be confirmed from outside
- A chimney fire or other event may have damaged concealed parts
- Smoke, fumes or odors continue and the cause is not visible
- The chimney passes through walls or floors and the condition of the enclosed section is in doubt
It is not a routine check and is not needed for most homes. Most chimneys are properly assessed at Level 1 or Level 2.
What it can involve
| Possible step | Why it is done |
|---|---|
| Removing a section of chase siding, drywall or finish | To see the chimney or the framing where it is otherwise hidden |
| Opening masonry at a suspect spot | To check for hidden cracks, voids or damage |
| Examining clearances to combustible framing | To see whether heat has reached what is behind the chimney |
| Further examination of the flue | To find the extent of damage found at Level 2 |
We explain beforehand what would be opened, why, and how it would be closed up again. Nothing is taken apart without your agreement. A Level 3 inspection is a diagnosis, and repairs are a separate decision.
If you are unsure which level you need, start with a chimney inspection. We tell you honestly if the findings point to Level 3.

Is Level 3 more expensive than Level 2?
It involves more work, so it usually costs more. We explain what is involved before we begin.
Do I need Level 3 to sell my house?
