Inspections
A closer look, from crown to firebox
A visual inspection notes what you can see from crown to firebox — cap, masonry, liner sections, and firebox surfaces — so you can discuss condition and next steps with a qualified local professional.
Exterior stack
- Crown and cap — Cracks in the concrete crown or rust on a metal cap may let water into the flue.
- Visible masonry — Spalled brick faces, open head joints, or white efflorescence signal moisture paths.
- Roof transition — Step flashing and counter-flashing should sit tight where the stack meets shingles.
Fireplace and flue
Liner — Clay tiles, metal, or poured liners each show wear differently; offsets and gaps may be visible with a light.
Firebox and throat — Cracked firebrick, missing mortar, or a throat plate that does not seat can change how smoke behaves in the opening.
Draft indicators — Smoke staining above the opening, odors when the damper is closed, or sluggish draw on a still day are common signs to describe when you meet with a sweep or inspector.
Questions to bring
Photos from the ground, dates of last sweeping, and appliance type help a sweep or inspector start with context. Note when water entered the flue or when you changed fuel types.
