Chimney sweep cost is usually straightforward for a basic cleaning, but repair estimates vary a lot depending on what an inspection actually finds.
What to look for
- Level of inspection — a basic visual check is different from a full video-scope inspection, and the quote should specify which was done.
- Creosote buildup level documented, since this drives both cleaning difficulty and fire risk.
- Liner condition — a damaged flue liner is a common and legitimate reason for follow-up repair costs.
- Certification — CSIA-certified sweeps are a reasonable baseline to ask about.
