Chimney Sweep & Inspection Cost
Estimate what a chimney sweep and inspection should cost — by service (cleaning, inspection, or both), what the chimney vents (gas, wood fireplace, or wood stove), inspection level (1 vs. 2), creosote buildup, and number of flues.
Estimate what a chimney sweep and inspection should cost. The price depends on the service (cleaning, inspection, or both), what the chimney vents (a gas fireplace cleans cheapest; wood builds creosote), the inspection level, and how much buildup there is.
Service
What you need done. A sweep (cleaning) removes soot and creosote; an inspection checks the chimney's condition and safety. Most homeowners get both once a year — a sweep includes a basic visual check, and adding a documented inspection catches problems early. Pick 'inspection only' if you just need a safety check (e.g. buying a home) with no cleaning.
What it serves
The appliance the chimney vents, which sets the cleaning cost. A gas fireplace burns clean and is cheapest to service. A wood-burning fireplace builds creosote and soot, so it costs more. A wood stove or insert burns hot and hard and is the most involved to clean. (If you chose inspection only, this doesn't affect the price.)
Creosote buildup
How dirty the chimney is. Choose 'light / routine' for a chimney swept in the last year or two. Choose 'heavy creosote' if it's been many years, you burn a lot of wood (especially unseasoned), or there's thick, glazed, or third-degree creosote — heavy buildup takes more time and specialized work, raising the cost. (Applies to the cleaning, not the inspection.)
Inspection level
How thorough the inspection is. Level 1 is the standard annual visual check of the readily accessible parts — it's what comes with a routine sweep. Level 2 adds a video-camera scan of the entire flue plus checks of attics and crawlspaces, and is required when you buy or sell a home, after a chimney fire or a weather event, or when you change the appliance or fuel. (A Level 3 structural inspection — tearing into masonry — is a separate, far pricier job, roughly $900–$5,000, not estimated here.)
Number of flues
How many separate flues (vertical passages) are being serviced. Most homes have one per chimney, but a chimney stack can carry several — e.g. a fireplace flue plus a furnace or water-heater flue. Additional flues on the same visit cost less than the first.

Sweep and inspect once a year
Fire-safety pros recommend an annual chimney inspection, and a sweep whenever there's meaningful buildup. A routine Level 1 inspection comes with a standard sweep, so the common annual visit is both together. Burning seasoned (dry) wood dramatically slows creosote buildup and keeps future sweeps cheaper and safer.
This is the service only — repairs cost extra
The estimate covers cleaning and inspection, not any repairs the inspection turns up — relining, a new crown or cap, flashing, or masonry work are all priced separately. If the chimney hasn't been serviced in years, budget a cushion in case the sweep uncovers something.
Estimate = sweep (by appliance, adjusted for creosote buildup) + inspection (by level), scaled for the number of flues. Excludes repairs and Level 3 structural inspections ($900–$5,000). Price also varies with chimney height, roof access, and region. 2026 national-average figures — get a local quote to confirm.
💡About this calculator▼
A chimney sweep and inspection is cheap insurance against two expensive, dangerous problems: a chimney fire from creosote buildup, and carbon monoxide from a blocked or cracked flue. The trouble is that "how much does a chimney sweep cost" doesn't have one answer — it depends on what you're actually having done, what the chimney serves, and how dirty it is. This calculator sorts that out, estimating the cost for a cleaning, an inspection, or the common annual combination of both.
Three things drive the price. The first is the service: a sweep (cleaning) removes soot and creosote, an inspection checks the chimney's condition and safety, and most homeowners get both once a year — a routine sweep already includes a basic visual (Level 1) inspection, so the two go together naturally. The second is what the chimney vents: a gas fireplace burns clean and is the cheapest to service, a wood-burning fireplace builds creosote and costs more, and a wood stove or insert burns hard and is the most involved to clean. The third is how much buildup there is — a chimney that hasn't been swept in years, or one that's burned a lot of unseasoned wood, can have heavy, glazed creosote that takes extra time and specialized work.
The calculator also handles the inspection level, which trips a lot of people up. A Level 1 inspection is the standard annual visual check and comes with a sweep. A Level 2 inspection adds a video-camera scan of the entire flue and is specifically required when you buy or sell a home, after a chimney fire or major storm, or when you change the appliance or fuel — it costs more because it's far more thorough. (A Level 3 inspection, which involves tearing into masonry to find structural problems, is a rare and much pricier job that this tool flags but doesn't estimate.) One honest note: this prices the sweep and inspection *service* only — if the inspection turns up repairs like a new liner, crown, or cap, those are billed separately.
The estimate adds up the services you select, adjusts for buildup, and scales for the number of flues.
Sweep (cleaning), by what it serves: • Gas fireplace ≈ $80–$150 — burns cleanest, least to do. • Wood-burning fireplace ≈ $100–$250 — creosote and soot. • Wood stove / insert ≈ $130–$300 — burns hot and hard, most involved. Heavy creosote buildup raises the cleaning cost by roughly half.
Inspection, by level: • Level 1 (basic visual, included with a sweep) ≈ $100–$250. • Level 2 (video-camera flue scan; sales, post-fire, appliance changes) ≈ $300–$600. Level 3 (structural, invasive) runs $900–$5,000 and isn't estimated here.
Then: total = sweep + inspection, with each additional flue adding about 60% of the first (same visit). A sweep-plus-Level-1 combo on a wood fireplace lands around $250–$500 — right where the industry prices the standard annual service.
📐How it's calculated▼
Total = sweep + inspection, scaled by flues.
Sweep = base (gas $80–150 · wood fireplace $100–250 · wood stove $130–300) × buildup (light 1.0, heavy 1.5) Inspection = Level 1 $100–250 · Level 2 $300–600 Flue scaling = 1 + (flues − 1) × 0.6
Example — annual sweep + Level 1 inspection, wood fireplace, light buildup, 1 flue:
Sweep = $100–$250 · Inspection (L1) = $100–$250 → Total ≈ $200–$500
Example — sweep + Level 2 video inspection, wood stove, heavy creosote, 2 flues:
Sweep = $130–$300 × 1.5 = $195–$450 · Inspection (L2) = $300–$600 → × flue factor 1.6 → Sweep ~$310–$720 + Inspection ~$480–$960 = Total ≈ $790–$1,680

🔍Finding your inputs▼
Service: What you need done. A sweep cleans out soot and creosote; an inspection checks the chimney's condition and safety. Both is the standard annual visit — and since a routine sweep already includes a basic visual inspection, getting them together is efficient. Choose inspection only if you just need a safety check without a cleaning, such as when buying a home or after a chimney fire.
What it serves: The appliance the chimney vents, which sets the cleaning cost. A gas fireplace burns clean and is the cheapest and quickest to service. A wood-burning fireplace deposits creosote and soot and costs more. A wood stove or insert burns hot and is used heavily, making it the most involved (and priciest) to clean. If you picked inspection only, this doesn't change the price.
Inspection level: How thorough the inspection is. Level 1 is the routine annual visual check of the readily accessible parts — it's what comes with a standard sweep, and it's enough if you use the chimney regularly and nothing has changed. Level 2 adds a video-camera scan of the entire flue plus checks of attics and crawlspaces; it's *required* when you buy or sell a home, after a chimney fire, earthquake, or major storm, or when you change the appliance or fuel type. A Level 3 inspection (removing masonry to investigate structural damage) is a separate, much costlier job — $900 to $5,000 — that this calculator notes but doesn't estimate.
Creosote buildup: How dirty the chimney is, which affects the cleaning cost. Choose light / routine if it's been swept within the last year or two. Choose heavy creosote if it's been many years, you burn a lot of wood (especially green or unseasoned wood, which produces far more creosote), or there's thick, tarry, or glazed (third-degree) creosote — heavy buildup takes more time and sometimes specialized removal, raising the price. This applies to the cleaning, not the inspection.
Number of flues: How many separate flues are being serviced. A flue is the vertical passage that carries smoke or exhaust up and out; most homes have one per chimney, but a single chimney stack can hold several — for example, a fireplace flue alongside a furnace or water-heater flue. Because the sweep is already on-site, each additional flue costs less than the first. If you're not sure, one is the common case.
⚠️Special situations▼
How often should I have my chimney swept and inspected?
The widely accepted guidance, from the Chimney Safety Institute of America (CSIA) and the National Fire Protection Association, is that chimneys should be inspected at least once a year, and swept whenever there's a meaningful amount of buildup — so most people schedule both together annually, typically before the heating season. The inspection is the non-negotiable part: an annual Level 1 inspection catches creosote buildup, blockages (animal nests are common), cracks, and venting problems before they become a fire or carbon-monoxide hazard, and it applies to every chimney, including gas ones that barely dirty the flue. The sweeping frequency depends on use: a fireplace or wood stove burned regularly can need cleaning every year (or even mid-season for heavy use), while one used only occasionally might go a bit longer — the practical trigger is creosote reaching about 1/8 inch of buildup, which a sweep will tell you. Burning dry, seasoned wood dramatically slows creosote accumulation, so how and what you burn matters as much as how often. Beyond the annual cycle, get a Level 2 inspection at specific trigger points regardless of timing: when buying or selling the home, after a chimney fire or a major event like an earthquake or severe storm, or whenever you change the appliance or fuel. Skipping annual service to save money is a bad trade — chimney fires and CO leaks are exactly the outcomes this inexpensive maintenance prevents, and letting buildup accumulate makes the eventual cleaning harder and more expensive anyway.
Do I really need a chimney inspection for a gas fireplace?
Yes — a gas fireplace and its chimney or vent still need an annual inspection, even though they barely produce the creosote that makes wood-burning sweeps necessary. The cleaning side is minimal (which is why servicing a gas fireplace is the cheapest option), but the inspection matters just as much as it does for wood, because gas appliances create their own hazards: the vent or flue can become blocked by debris, bird or animal nests, or a collapsed liner; the flue can corrode (gas combustion produces moisture and acidic byproducts that eat at metal and masonry over time); and any blockage or leak can send carbon monoxide back into the house, which is odorless and deadly. An annual inspection checks that the venting is clear and intact, the connections and components are sound, the logs and burner are positioned correctly, and there's no corrosion or deterioration. So the honest framing is: for a gas fireplace, you're paying mostly for the inspection and safety check, not a heavy cleaning — but that inspection is exactly the point. Don't skip it on the assumption that 'gas is clean.' If you're only servicing a gas unit, choose 'inspection only' or 'sweep + inspection' in the calculator with the gas appliance selected; the cost is modest, and it's the cheapest peace of mind in home maintenance.
What's the difference between a Level 1 and Level 2 inspection, and which do I need?
The levels describe how thorough the inspection is, and which one you need depends on your situation, not preference. A Level 1 inspection is the standard annual check: the technician visually examines the readily accessible portions of the chimney and flue — the parts they can see without special tools or dismantling anything — and confirms it's structurally sound, clear of obstructions and combustible deposits, and safe to use. It's included with a routine sweep and is all you need when you use the chimney regularly, nothing has changed, and there's no reason to suspect a hidden problem. A Level 2 inspection includes everything in a Level 1 plus a video-camera scan of the entire flue interior (catching cracks, gaps, and blockages a visual check can't reach) and inspection of accessible areas like the attic, crawlspace, and roof. A Level 2 is required — not optional — in specific circumstances: when you buy or sell a home (it's a standard part of due diligence and often required by the sale), after any event that could have damaged the chimney (a chimney fire, an earthquake, a lightning strike, or a severe storm), and when you make a change to the system such as installing a new appliance, a new liner, or switching fuel types. Because it uses camera equipment and covers far more, it costs more — typically $300–$600 versus $100–$250 for a Level 1. A Level 3 inspection goes further still, involving the removal of components or masonry (walls, chimney crown, etc.) to investigate a serious suspected hazard the lower levels couldn't confirm; it's rare, invasive, and expensive ($900–$5,000), and a professional will only recommend it if a Level 1 or 2 found evidence of a hidden structural problem. The simple rule: annual maintenance and normal use → Level 1; buying/selling, after a damaging event, or a system change → Level 2; and let a pro tell you if the rare Level 3 is warranted.
The sweep found problems that need repair — why isn't that in the estimate?
Because a sweep-and-inspection is a service, and repairs are a separate scope of work with their own (often much larger) costs — this calculator deliberately prices only the cleaning and inspection so the estimate stays honest and comparable, rather than blending in repair costs that vary enormously. The inspection's whole job is to *find* problems, and chimneys develop plenty: a cracked or deteriorated flue liner (a serious safety issue, and relining can cost anywhere from several hundred to a few thousand dollars depending on the method), a damaged or missing chimney crown or cap (letting in water and animals), failing flashing where the chimney meets the roof (a common leak source), spalling or crumbling masonry and mortar joints (tuckpointing or rebuilding), or damage from a past chimney fire. Any of these can run from a couple hundred dollars for a simple cap to several thousand for major masonry or a full reline. So when a sweep hands you a quote for repairs on top of the cleaning, that's normal — the cleaning got you the diagnosis, and the repair is the fix. A few practical tips: get the specific problem and recommended repair in writing (ideally with the video from a Level 2 scan if it's structural), get a second opinion and competing bids for anything expensive, and be a little wary if a very cheap sweep aggressively upsells major repairs, since that's a known bait-and-switch pattern in the industry — using a CSIA-certified professional helps. Budget-wise, if your chimney is old or hasn't been serviced in years, it's wise to keep a repair cushion in mind when you book the sweep, because the odds of finding something go up the longer it's been.
❓Common questions▼
How much does it cost to have a chimney swept?
A professional chimney sweep typically costs between about $129 and $381 for an annual cleaning, with the average homeowner paying around $254 — but the price depends heavily on what the chimney serves and how dirty it is. By appliance, a gas fireplace is cheapest to clean at roughly $80–$150 because it produces little residue; a wood-burning fireplace runs about $100–$250; and a wood stove or insert, which burns hot and is often used heavily, runs about $130–$300. On top of that, heavy creosote buildup — from years without a cleaning or from burning a lot of unseasoned wood — raises the cost, because thick or glazed creosote takes more time and sometimes specialized removal. Most homeowners actually get a sweep and an inspection together as their annual service, which typically runs $250–$500, since a routine cleaning already includes a basic Level 1 visual inspection. Other factors that move the price include your chimney's height and how easy it is to access from the roof, your region, the number of flues, and the individual company (some have trip minimums, others include the inspection free). The calculator above lets you enter your specific service, appliance, buildup, and flue count to get an estimate tailored to your situation. Remember it covers the cleaning and inspection only — any repairs the sweep finds are priced separately.
How much does a chimney inspection cost?
A chimney inspection costs about $100–$250 for a standard Level 1, and $300–$600 for a more thorough Level 2 that includes a video-camera scan of the flue — with the rare, invasive Level 3 running $900–$5,000. The level you need depends on your situation. A Level 1 is the routine annual visual inspection of the readily accessible parts of the chimney and flue; it's what comes bundled with a standard sweep and is all that's needed for regular maintenance when nothing about the system has changed. A Level 2 adds a video scan of the entire flue interior plus checks of attics, crawlspaces, and the roof, and is required — not optional — when you buy or sell a home, after a chimney fire or a major event like an earthquake or severe storm, or when you change the appliance, liner, or fuel type; it costs more because it's far more comprehensive and uses camera equipment. A Level 3 inspection involves removing masonry or components to investigate a serious suspected structural problem and is only done when a lower-level inspection found evidence of a hidden hazard. Because a Level 1 is usually included with a cleaning, many homeowners effectively get their annual inspection as part of a $250–$500 sweep-and-inspect visit. Use the calculator above to estimate an inspection on its own or bundled with a sweep, and to see the difference a Level 2 makes.
Is a chimney sweep and inspection worth it?
Yes — it's one of the highest-value, lowest-cost pieces of home maintenance there is, because the roughly $130–$500 a year it costs prevents two genuinely dangerous and expensive outcomes: chimney fires and carbon-monoxide leaks. Creosote, the tarry residue that wood fires deposit in the flue, is highly flammable, and enough buildup can ignite into a chimney fire that spreads to the house; regular sweeping keeps it from accumulating to dangerous levels. The inspection side guards against the quieter hazard: a blocked, cracked, or deteriorated flue can leak carbon monoxide — colorless, odorless, and potentially fatal — back into your living space, and it can also let water in to rot framing and ruin masonry. An annual inspection catches these problems, plus blockages from animal nests and debris, before they cause harm or turn into major repairs. This is true even for gas fireplaces, which barely need cleaning but still need the venting checked for blockages and corrosion. Beyond safety, staying on top of service is cheaper in the long run: letting creosote or damage accumulate makes the eventual cleaning harder and repairs more extensive, and if you're selling the home, a recent clean inspection (a Level 2) smooths the sale. The one caveat is to use a reputable, CSIA-certified sweep, since the industry has some bad actors who upsell unnecessary repairs — but the core service itself is unambiguously worth it. Enter your details in the calculator above to see what it should cost for your setup.
What makes a chimney sweep cost more?
Several factors push a chimney sweep above the baseline, and knowing them helps you understand a quote. The biggest is what the chimney serves and how it's used: a wood stove or insert burned heavily costs more to clean than a wood-burning fireplace, which costs more than a gas fireplace that barely dirties the flue. Close behind is the amount of buildup — a chimney that hasn't been swept in years, or one used to burn a lot of green or unseasoned wood, can have thick, tarry, or glazed (third-degree) creosote that takes extra time and sometimes specialized products or tools to remove safely, raising the price meaningfully. Access and configuration matter too: a tall chimney, a steep or hard-to-reach roof, or a design that's awkward to service adds labor, and multiple flues (a single stack sometimes carries a fireplace flue plus a furnace or water-heater flue) each add cost, though additional flues on the same visit are cheaper than the first. The inspection level layers on top — a routine Level 1 comes with the sweep, but a Level 2 video inspection adds a few hundred dollars. Region and the individual company also swing the number, since labor rates vary and some sweeps have trip minimums or bundle the inspection free. Finally — and separately — if the inspection uncovers repairs (a cracked liner, a failing crown or cap, masonry damage), those are billed on top of the cleaning and can dwarf it. The calculator above lets you adjust appliance, buildup, inspection level, and flue count to see how each factor moves the estimate.
