Chimney Sweep & Repair Cost Guide (2026)
Updated November 2026
A routine chimney sweep is $130–$380 (average $255). The expensive part is everything the sweep finds: a liner replacement runs $1,800–$4,000, a crown $750–$1,000, and a repair $160–$750. That's why the industry pushes the Level 2 video inspection — it's the only way to price the real job before you light a fire.

Bands are per job, not per hour, and publisher spreads on liners and crowns are wide. Where two outlets agree, the band above follows them and the outlier is flagged in the dataset rather than averaged in.
Sweep vs cleaning vs inspection
- Sweep — $130–$380. Brushing and vacuuming the flue, plus a visual check. This is the annual maintenance visit most homes actually need.
- Cleaning with Level 2 inspection — $100–$500. Adds a video scan of the flue. Standard for a home purchase, an appliance change, or after any chimney fire. Fixr's average of $400 reflects this fuller scope.
- Level 3 inspection. Opens concealed areas when a defect is already suspected. Not a routine purchase; priced as a diagnostic.
Repair, cap, crown, liner — what each buys
| Item | Cost | When it's needed |
|---|---|---|
| Cap | $300–$600 | Uncapped flue; rain, birds, debris |
| Crown | $750–$1,000 | Cracked crown leaking into the masonry |
| Repair | $160–$750 | Pointing, flashing, small masonry defects |
| Liner | $1,800–$4,000 | Cracked or missing flue liner — safety item |
What drives the price
- Flue condition — a blocked or damaged flue turns a sweep into a repair.
- Access — roof pitch, height, and chimney location set the labor time.
- Appliance type — wood, gas, and oil flues need different cleaning and inspection.
- Masonry vs prefab — prefab liners are replaced as assemblies; masonry can be relined.
- Region — heating-season demand and local labor rates move the bands.
How to compare chimney quotes
- Ask for the inspection level — a sweep quote is not a Level 2 inspection quote.
- Get photos or video — any recommended repair should come with the flue footage.
- Separate safety from cosmetic — liner and crown are safety; repointing can often wait.
- Confirm credentials — ask for chimney-sweep certification and insurance before work starts.
Related cost guides
- Roof replacement cost — chimney flashing and crown work are usually quoted with the roof.
- HVAC cost guide — wood and gas appliances share the venting and combustion-safety checks.
- Duct cleaning cost — the other annual vent-and-flue maintenance line most homes defer.
- Mold remediation cost — a leaking crown or flashing is how attic mold starts.
FAQ
How much does a chimney sweep cost?
A standard sweep runs $130–$380 with a national average of $255 (Bob Vila). A sweep brushes and vacuums the flue; a cleaning that includes a Level 2 video inspection is priced higher — $100–$500 with an average around $400 (Fixr). Ask which one the quote covers.
How often does a chimney need cleaning?
The usual rule is once a year for a wood-burning fireplace in regular use, and more often if you burn a lot or burn green wood. Gas appliances still need an annual inspection even though they produce little creosote. The inspection matters more than the brushing: it's what catches a cracked liner or blocked flue before it becomes a fire risk.
How much does chimney repair cost?
Most repairs run $160–$750 (Bob Vila, average $455). That band covers pointing, flashing, and small masonry fixes. A crown rebuild is $750–$1,000; a liner replacement is $1,800–$4,000. If the quote is for a partial rebuild, get a second opinion — rebuild pricing is a different scope and isn't in this table.
What is a chimney liner and why does it cost so much?
A liner is the flue's inner pipe; it contains combustion gases and protects the masonry. Installing a flexible double-wall stainless liner runs $1,800–$4,000 (Fixr, average $2,500). It's the most expensive routine chimney job because it's a full-length installation with fittings and insulation, not a surface repair. Bob Vila's band runs higher ($2,500–$7,000) — spreads are flagged in the dataset.
Do I need a Level 1, 2, or 3 inspection?
Level 1 is the visual check included with a routine sweep. Level 2 adds a video scan of the flue and is the standard for a home sale, a change of fuel/appliance, or after a chimney fire. Level 3 opens concealed areas and is reserved for a known problem. Only a Level 2 or 3 can actually see a cracked liner — a $130 sweep is not an inspection.
Is a chimney cap worth it?
Yes, if the chimney is uncapped. A cap is $300–$600 installed and it keeps rain, birds, and debris out of the flue — water is the most common cause of masonry deterioration. It's the cheapest preventive item on this page, and the one most often missing.

Two conflicts are flagged in the dataset: crown repair (Fixr and Bob Vila publish $750–$1,000; HomeAdvisor publishes $150–$350) and liner spread (Fixr $1,800–$4,000 vs Bob Vila $2,500–$7,000).
