Chimney Cleaning
Creosote and soot cleared from the full flue, with an inspection included. The annual visit that keeps a burn season uneventful.
Book it before the first cold night, not after the first fire that smokes.
Chimney cleaning removes the creosote and soot that every fire leaves behind, and a proper visit includes the inspection rather than charging for it separately. Once a year is the standard for a fireplace in regular use, and late summer through early autumn is the right window — partly because deposits have had a season to dry out, mostly because everyone books in November and the wait is three weeks by then.
The visit
Firebox to cap, in one pass
Booked late summer, a clean leaves time to fix anything it turns up. Booked in November, you are competing with everyone else who remembered.

Signs you need chimney cleaning
You burn most evenings through the winter
Usage is the first input. A fireplace lit most nights through a real winter puts down in one season what an occasional fire takes three to accumulate — twice a season is the realistic interval, not once.
The wood was not split and covered a year ago
Fuel matters more than frequency. Unseasoned or resinous softwood burns cooler and wetter, and a flue running cool is a flue condensing creosote. The same fireplace on dry hardwood can go a full season comfortably.
You damp the fire right down overnight
A smouldering fire is the single biggest creosote producer there is — low temperature, incomplete combustion, hours of it. If this is the habit, plan on the interval being shorter than the calendar suggests.
You moved in and nobody mentioned the chimney
No record means no interval to work from, and the fireplace may have gone years untouched or been swept last spring. Booking one visit converts an unknown into a date you can count from.
It is August and the fireplace is still on the list
Late summer is the cheap window in every sense. Anything the visit turns up still has months of warm weather to be repaired in, and you are not behind everyone who remembered on the first cold Saturday.
Something changed — a new stove, a new insert, a new fuel
A flue sized for one appliance rarely suits the next, and the deposit pattern changes with it. A change of appliance or fuel resets the interval rather than continuing it, and it is also one of the events NFPA 211 names for a Level 2 look.
How the visit works
The same four steps every time, whatever the repair turns out to be.
- 01
Inspection first, always
A look at the crown, cap, flashing and exterior masonry, then the flue, damper and firebox — with a camera where the job calls for a level 2 scan. Whatever needs work gets shown to you, not just described.
- 02
A written estimate before anything
Scope, price and what is not included, in writing. Nothing starts until you approve it, and an emergency is not a reason to skip this step.
- 03
The work itself
Matched materials and the manufacturer's spec, not whatever is on the van. Drop cloths down, and the room left as it was found.
- 04
Verification and a report
A second scan after the work, and written findings you can keep, hand to an inspector, or send to an insurer.
The jobs this actually includes
Not every job on this list is equally urgent, so they are ordered that way. A cracked liner stops you using the fireplace tonight; waterproofing can wait for a dry week.
The job — most urgent first
What it involves
On site
Annual fireplace cleaning
Safety repairThe standard visit: full flue brushed, smoke shelf and firebox cleared, hearth sealed and a HEPA vacuum running throughout. Includes the Level 1 inspection.
On site: 1–2 hours
Wood stove and insert cleaning
Safety repairA sealed appliance burns hotter and longer, so the liner needs doing more often than an open fire, not less. The connector pipe is cleaned as part of it.
On site: 1–2 hours
Glazed creosote treatment
Safety repairStage three creosote is a hard glaze a brush slides straight over. It is broken down chemically or taken off with a rotary head, and it is a separate job with its own price.
On site: Half a day
Multiple flues in one stack
StructuralOlder houses often run two or three flues up one chimney. Each is cleaned and scanned separately, because a blockage in one can push smoke into the other.
On site: Half a day
Cleaning before a house sale
PreventiveCleaned first, then scanned, then written up — in that order, because a sooty flue hides exactly what a buyer's inspector will be looking for.
On site: Half a day
Times are for the work itself, not for scheduling. Masonry needs roughly 40°F to cure properly, which is what limits this work in a northern winter rather than whether a crew is free.
Why chimney cleaning quotes vary so much
- How many flues the chimney serves
- Creosote stage — glazed deposits are a different job, not a longer clean
- Whether the appliance is an open fire, a stove or a sealed insert
- Roof access and pitch, if the flue has to be worked from the top
- Whether a nest or blockage has to come out before brushing can start
A standard annual clean on one open fireplace is a flat modest price and should include the inspection. What raises it is glazed creosote, a second flue, or a blockage. All three are quoted before work starts rather than added to the invoice afterwards.

Common questions
How often does a chimney need cleaning?
Work it out from how you burn rather than from a rule. Dry hardwood, a hot fire, a few evenings a week: once a season is comfortable. Most nights, or softwood, or a fire damped down overnight: plan on twice. A fireplace lit three times all winter still needs its annual look, because a nest, a cracked tile or a rusted cap do not care how often you light it — that part is the inspection rather than the cleaning, and the two travel together for a reason.
When is the best time to book chimney cleaning?
Late summer to early autumn. Deposits have had a dry season to settle, any damage found still leaves time to repair before you need the fireplace, and you are not competing with everyone who remembered on the first cold weekend in November. Booking in season is not dangerous, it is just slower and more expensive to fix anything that turns up.
How much does chimney cleaning cost?
Ask what the quoted number includes before you compare two of them, because that is where the difference usually is rather than in the price. A quote covering one open fireplace with the Level 1 inspection included is not the same product as a cheaper one without it. Three things move the figure upward and all three are quoted before work starts: glazed stage-three creosote needing chemical treatment or a rotary head, a second or third flue in the same stack, and a blockage that has to come out before a brush can pass.
Will chimney cleaning make a mess in my house?
It should not, and it is a fair thing to settle when you book rather than discover afterwards. Ask two questions: is the fireplace opening sealed, and does a HEPA vacuum run for the whole visit rather than at the end? Those two are what keep the room under negative pressure while the brush is working. A company that does both leaves the hearth cleaner than it found it.
Is chimney cleaning the same as a chimney sweep?
Yes. Two names for one visit — the trade says sweeping, most homeowners say cleaning, and you will get the same work whichever you book. The difference worth asking about is not the name but whether the visit includes an inspection and a camera scan of the flue, because plenty of cheap cleans do not.
