The fix list first, then what triggers each item

Cap: the top of the flue is open or damaged. Leak repair: water is getting in. Cricket and flashing: water is pooling where the chimney meets the roof. Crown: the top slab is cracked. Liner: the flue's inner wall has gaps. Chase cover: the metal lid on a framed chimney is failing.

Damper: it will not seal. Mortar and masonry: joints and bricks are eroding. Smoke chamber: the area above the firebox is damaged. Firebox: its walls or floor are cracked. Gas insert: the owner wants a gas heater in place of an open fire.

It does not mean a government agency rejected your chimney. It means the report names conditions that NFPA 211 or the local building code would not accept as they stand, and those want repair before anyone lights the fireplace.

In a sale, the buyer can bring those items to the seller as a repair request, a credit or a re-inspection. The parties and agents settle it, and we give no legal advice. What we can do is price the work so those talks have numbers in them.

Gas insert: $2,800 to $5,600. Cricket: $445 to $1,010, rising to $670 to $1,650 once a full flashing replacement is included. A cap costs $165 to $670, and fixing a leak costs $560 to $3,350.

The rest depend on what the camera finds. That covers brick work and mortar, a chase cover, the damper, the liner, the crown, flashing by itself, the firebox and the smoke chamber. We quote them in writing afterward, with options side by side where more than one fix would do.
