Chimney Sweep Cost Calculator
A chimney sweep runs about $233 in Atlanta for one open fireplace flue, and $154 each if three are done on the same visit. ⚠️ The brushing is the cheap part. A level 2 inspection — a camera down the full flue, and the one to ask for when buying a house, changing the appliance or after a chimney fire — is $487. A steep or high roof is $476 rather than $233. And a flue with hard glazed creosote is $628, because that does not sweep off at all.

⚠️ A level 1 inspection is what comes with an ordinary sweep and it looks at what can be reached without tools. It is the right level when nothing has changed and nothing has gone wrong — but if you are buying the house, changing the appliance or have had a chimney fire, the level to ask for is 2, and it is the one almost nobody knows exists. On this flue that is 215 or so more.

The figure above is already calculated. Each step just makes it more yours, and you can stop at any of them.
Sweeping is the cheap part. What you are really buying is an inspection
The trade has three levels and they are different products at different prices. Almost nobody outside the trade knows the second one exists, and it is the one that matters.
| What you are buying | Hours | With the sweep |
|---|---|---|
| Level 1 — what can be seen without toolsSees: the readily accessible parts, by eye and by torch | 2.6 | $233 |
| Level 2 — a camera down the flueSees: the whole flue on video, plus attics, crawl spaces and the rest of its run | 3.4 | $487 |
| ⚠️ Level 3 — opening it upSees: what is behind the masonry, once some of it has been removed | 6.1 | $1,411 |
“Why is chimney sweeping so expensive?” and “do you really need a chimney sweep?” are both questions Google shows on this search, and they have the same answer: the brushing is $233 of somebody’s morning, and the reason to book it is the pair of eyes that comes with it. ⚠️ Level 2 is the one to ask for by name in three situations — you are buying the house, you are changing the appliance, or there has been a chimney fire — because a camera going down the full length is the only thing that finds a cracked liner, and a chimney fire cracks liners in places nothing else can see. It is $253 more than the sweep you were going to book anyway. A general home inspector looks at your fireplace; nobody looks up it unless you pay for this.
And there is a state a chimney gets into where sweeping is not the service
| What is on the flue | Does a brush take it off? | Hours | Cost |
|---|---|---|---|
| Soot and light dust | Yes | 2.6 | $233 |
| Crunchy flakes | Yes | 3.3 | $268 |
| ⚠️ Hard, shiny glaze | ⚠️ No, never | 7.1 | $628 |
⚠️ The last row is not a dearer sweep, it is a different job, and that is the single most useful thing on this page. Glazed creosote is tar that has set hard onto the flue and it does not come off with a brush at any price — it takes a chemical treatment applied over several fires to make it brittle, then rotary chains run down the liner to cut it out, which means two visits weeks apart. It is also the state that causes chimney fires, so it is the one worth $628. The way you avoid ever paying it is the row above: keep the flue at soot and light dust by burning dry wood hot, because the EPA is blunt about where this starts — “Wood burns best at a moisture content of less than 20 percent. Test wood with a wood moisture meter before you burn it”. A moisture meter costs less than one sweep, and wet wood is what turns row one into row three.
What it costs if the camera finds something
None of this is priced on this page. These four come from our chimney repair model, at its own default chimney, so the two pages cannot drift apart.
| The repair | Cost | In sweeps |
|---|---|---|
| Fit a rain cap and spark arrestor | $2,422 | 10 |
| Rebuild the crown, the concrete cap on top | $3,073 | 13 |
| Repoint the mortar joints | $3,192 | 14 |
| Install a stainless steel flue liner | $3,901 | 17 |
A stainless liner is 17 sweeps — which is the whole argument for booking the cheap thing, put as arithmetic rather than as advice. ⚠️ And one cause of all four is worth knowing here rather than there: a chimney that does not reach the height the trade’s 3-2-10 rule asks for draws badly, a flue that draws badly runs cool, and a cool flue is exactly what deposits creosote. The height is not a masonry question, it is the cause upstream of this page.
| Roof pitch | 2 ft from the ridge | 5 ft from the ridge | 10 ft from the ridge |
|---|---|---|---|
| 3:12 | 3 ft | 3.3 ft | 4.5 ft |
| 4:12 | 3 ft | 3.7 ft | 5.3 ft |
| 6:12 | 3 ft | 4.5 ft | 7 ft |
| 8:12 | 3.3 ft | 5.3 ft | 8.7 ft |
| 10:12 | 3.7 ft | 6.2 ft | 10.3 ft |
| 12:12 | 4 ft | 7 ft | 12 ft |
⚠️ Trade practice, not a code reproduced here, and your local code decides. It is computed by our chimney repair page from your own roof rather than read off this table, and burning wood below 20 per cent moisture is the other half of keeping a flue warm enough not to tar up.

Where these numbers come from
- You are not buying brushing, you are buying an inspection
- “Why is chimney sweeping so expensive?” and “do you really need a chimney sweep?” are both asked on this search, and they have one answer: the brushing is $233 of somebody’s morning and the reason to book it is the pair of eyes that comes with it. The trade has three inspection levels and they are separate products. Level 1 is what comes with an ordinary sweep and looks at what can be reached without tools — firebox, damper, accessible flue, the outside. Level 2 puts a camera down the full length and looks at the parts that run through attics and voids: $487, or $254 more than the sweep you were booking anyway. Level 3 takes masonry apart to reach something concealed, starts around $1,412, and nobody buys it speculatively. ⚠️ Level 2 is the one to ask for by name in three situations — buying the house, changing the appliance, after any chimney fire — because a fire cracks liners where nothing else can see, and a cracked liner is how a flue puts combustion gases into a bedroom wall. A general home inspector looks at your fireplace. Nobody looks up it unless you pay for that.
- And there is a state where sweeping is not the service at all
- Creosote comes in three states and only two of them brush off. Soot and light dust is what a flue looks like after a season of hot fires with dry wood: $233. Dry crunchy flakes take more passes and a stiffer brush at $268, and they are a warning that the flue is running cooler than it should. Hard shiny glaze is tar that has set onto the liner and it does not come off with a brush at any price. What it takes is a chemical treatment applied over several fires to make it brittle, then rotary chains run down the flue to cut it out — two visits weeks apart, and $628 rather than $233. ⚠️ It is also the state that causes chimney fires, so a quote that treats a glazed flue as an ordinary sweep has not been up there to look. The way you never pay it is upstream of any sweep, and the EPA states it plainly in EPA, Best Wood-Burning Practices (read 2026-08-25): “Wood burns best at a moisture content of less than 20 percent. Test wood with a wood moisture meter before you burn it”. Wet wood smoulders, a smouldering fire runs cool, and a cool flue is what lays tar down. A meter that reads below 20 per cent costs less than one sweep.
- Why two identical flues get quoted so differently
- Almost none of the spread is the brushing. Rodding up from the hearth with a sheet and a vacuum is $233. A roof somebody can walk on is $306. A pitch nobody walks on, or three storeys up, is $476 — roughly double, and it is not padding: roof brackets, an anchor and lines or a hired tower, and two people rather than one. ⚠️ That is worth asking about before assuming a number is inflated, and it is worth knowing that the rigging goes up once however many flues are up there. The other half of the spread is how many flues share the call-out: one is $233, three on the same booking are $154 each. An older house often has three or four — the fireplace, a boiler flue, a bricked-up bedroom one — and they are routinely booked one at a time. And how much you burn decides how often rather than how much: a wood stove getting through three cords a year wants 2 visits, which is $543 a year rather than $272.
- The gas flue nobody sweeps, and what the camera finds
- A gas appliance deposits no creosote, and that is the reason its flue gets ignored rather than a reason to ignore it. What blocks a gas flue is a bird nest, debris or a collapsed liner, and the failure mode is not a chimney fire — it is carbon monoxide coming back into the house, which is why CDC, Carbon Monoxide Poisoning Basics (read 2026-08-25) is the relevant federal page and not a fire one. On this model that inspection is $204. The wider frame comes from U.S. Fire Administration, Heating fire safety (read 2026-08-25), which asks for cleaning and inspection each year by a professional, and reports that heating fires remained the second leading cause of home fires in 2021. An estimated 32,200 home heating fires were reported. ⚠️ What the camera finds is deliberately not priced here: a rain cap is $2,384 and a stainless liner $3,834 on our chimney repair page, which also computes the 3-2-10 height rule from your own roof rather than having it modelled twice. A liner is 16 sweeps, which is the argument for booking the cheap thing put as arithmetic rather than as advice. Labour is official: wages from BLS OEWS for maintenance and repair workers, general, May 2025, retrieved 2026-08-20, benefit-loaded from BLS ECEC. ⚠️ BLS publishes no occupation called chimney sweep, and that is said here rather than hidden: it is the closest published trade and the hours are our estimate. Every estimated band is on the dataset page and the whole approach on the method page.
- Material prices
- Modelled estimates, not sourced prices. No public, machine-readable source of US residential material prices exists, and we would rather say so than pretend otherwise. Each line carries its own uncertainty band. How we estimate them.

What this figure does not include
- Anything the inspection finds
- ⚠️ Deliberately not priced here, and it is most of what makes a chimney bill big. A cracked crown, a failed liner, repointing, a new cap — all of it is on our chimney repair page, priced whole, and this page shows those figures alongside rather than inventing a second set. One job, one model, one number.
- The 3-2-10 height rule
- Also not recalculated here: our chimney repair page already computes the height the trade rule asks for from your roof pitch and your distance to the ridge, and this page imports that figure rather than deriving it a second time. It matters on this page because a chimney that is too short draws badly, and a flue that draws badly runs cool — which is the condition that deposits creosote in the first place.
- The appliance itself
- Servicing a stove, a gas fire or a pellet burner is the manufacturer’s schedule and often a different trade. A sweep cleans the flue; whether the appliance is burning correctly is a question for whoever fitted it, and the two are booked separately more often than they should be.
- Firewood, which is where the problem starts
- ⚠️ Not a cost on this page and it is the cheapest lever there is. Wet wood burns cool and smoulders, and a cool, smouldering fire is what puts creosote on a flue — so what you burn does more to decide the state of the chimney than what you pay a sweep. The EPA publishes the number: wood burns best below 20 per cent moisture, and a meter costs less than a single sweep.
Questions people actually ask
How much does it cost to sweep a chimney?
About $233 in Atlanta for one open fireplace flue swept from inside the room, with the ordinary look-over that comes with it. Three flues on the same visit work out at $154 each, because the call-out is paid once. ⚠️ Two things move it far more than the brushing does. Working off a roof somebody cannot stand on is $476 rather than $233, because it is staging, fall protection and two people instead of one. And asking for a level 2 inspection — a camera down the full flue — is $487, which is the number worth knowing before you book.
Do you really need a chimney sweep?
If you burn anything, yes, and the reason is not soot. The U.S. Fire Administration puts it in one line: "Maintain heating equipment and chimneys by having them cleaned and inspected each year by a professional". The scale behind it is that heating fires remained the second leading cause of home fires in 2021. An estimated 32,200 home heating fires were reported. ⚠️ But the honest version of the answer is that the brushing is the cheap half — $233 of somebody's morning — and what you are really buying is the pair of eyes. A gas appliance deposits no creosote at all and still wants looking at once a year, because what blocks a gas flue is a bird nest or a collapsed liner and the failure mode is carbon monoxide coming back into the house rather than a chimney fire.
Why is chimney sweeping so expensive?
Because most of the bill is not brushing. On this model the call-out and the drive are paid once whatever is at your house, the sweep itself is 2.6 trade hours, and everything above $233 is either access or inspection. ⚠️ The two that surprise people: a steep or high roof is $476 against $233 for the same flue rodded from the hearth, because it is staging and a second person. And a flue with hard glazed creosote in it is $628 — not a dearer sweep but a different job, involving a chemical treatment over several fires and then rotary chains, which means the sweep drives to your house twice.
What is the 3:2-10 rule for chimneys?
Trade practice for how tall a chimney has to be: at least 3 feet above the point where it passes through the roof, and at least 2 feet above anything within 10 feet of it horizontally — including the roof itself as it rises towards the ridge. So on a 6:12 pitch a chimney 10 feet down-slope from the ridge needs 7 feet, and on a 12:12 it needs 12. ⚠️ It belongs on a sweeping page rather than only on a repair one, because a chimney that falls short draws badly, a flue that draws badly runs cool, and a cool flue is exactly what lays down creosote. Your local code decides, and our chimney repair page computes the height from your own roof.
