Start at the firebox and work up
An inspection should follow the path the combustion gases take. That means beginning at the firebox, checking the refractory or firebrick for cracks and missing mortar, then moving to the damper, the smoke shelf and the smoke chamber above it.
The smoke chamber is the part most often skipped and one of the most informative. A rough, stepped, unparged chamber tells you why a fireplace smokes and why creosote accumulates faster than the owner expects.
The liner is the finding that matters most
Liner condition determines whether the system is safe, and it cannot be assessed from either end by eye. A camera scan is the only reliable way to see cracked or offset clay tile, gaps at joints, or corrosion in a metal liner.
If an inspection report says nothing specific about the liner, it has not told you the one thing you most needed to know.
Then the exterior: crown, cap, flashing, masonry
From the roof, the crown should be a sloped slab with an overhang, not a thin flat wash. The cap should be secure with intact mesh. Flashing should be metal let into a mortar joint, not a smear of roofing tar.
Masonry gets checked for spalling faces, eroded joints and any lean. Those tell you how much water the structure has been taking and for how long.
What a useful report looks like
A report is useful when it separates safety findings from repairs to plan for and items to simply monitor. Without that distinction you cannot tell what to spend money on this month versus this decade.
Photographs matter too. If you can see the cracked tile or the broken crown yourself, you are in a position to get a second quote on equal terms.
Questions homeowners ask
- How often should this happen?
- Annually for any appliance in regular use, and before first use after buying a home or after a chimney fire.
