Chimney Sweep
A full system sweep from firebox to cap, with the flue scanned on the way. The annual visit that keeps creosote from becoming the problem.
Real homeowner reviews
The short answer
A sweep is not a cleaner. Half the value of the visit is what gets found on the way down.
The brushing is the easy part. What a chimney sweep is actually doing is reading the flue: how much creosote there is and which stage it has reached, whether the liner is intact, whether anything has been nesting in there, and whether the damper and firebox are sound. Stage one creosote brushes off. Stage three is a hard glaze that no brush will touch and needs chemical treatment or a rotary head. Knowing which one you have is the difference between an hour's work and a job.
The visit
Firebox to cap, in one pass
The hearth is sealed and a vacuum runs throughout. Soot in the room means the seal was not done properly.

Do you have this problem?
Signs you need chimney sweep
Black flaky buildup you can see in the flue
Shine a torch up past the damper. Anything more than a light dusting is due a sweep, and a shiny tar-like coating means it has gone past the stage a brush will clear.
Soot falling into the hearth
Deposits letting go of the flue wall. Harmless in itself, and a straightforward sign that there is more up there than there should be.
The fire is hard to light and slow to draw
A narrowing flue moves less air. If a fire that used to catch in minutes now needs coaxing, the passage has changed rather than the wood.
A campfire smell on warm damp days
Creosote is hygroscopic — it takes up moisture and gives off odour. A fireplace that smells in July has deposits in it, not a ventilation problem.
Birds, chattering or debris in the flue
Twigs on the smoke shelf, or noise in spring. A nest is both a blockage and a fire risk, and it means the cap is missing or broken.
It has been over a year, or you do not know
NFPA 211 asks for an annual inspection whether or not the fireplace has been used. Inheriting a house with a fireplace nobody has told you about counts.
How we work
How the visit works
The same four steps every time, whatever the repair turns out to be.
- 1
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.
- 2
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.
- 3
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.
- 4
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.
What it covers
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
Full system sweep, firebox to cap
Safety repairRods and brush through the full flue with the hearth sealed and a HEPA vacuum running, then the smoke shelf, damper and firebox cleared by hand. Nothing should end up in the room.
On site: 1–2 hours
Stage three creosote removal
Safety repairHard glazed creosote that a brush slides over. Treated chemically to break it down, or taken off with a rotary chain head. This is a separate job from a sweep and is priced as one.
On site: Half a day
Nest and blockage removal
Safety repairNesting material, leaves or a fallen brick cleared from the flue, and a cap fitted so it does not come back. Removal without a cap is a visit you will repeat.
On site: 1–2 hours
Gas and pellet appliance venting
StructuralNo creosote, but venting still blocks and still needs checking. Gas appliances fail quietly, which is the reason this is on the list at all.
On site: 1–2 hours
Camera scan with the sweep
PreventiveA clean flue is the only time the liner can actually be seen. Scanning immediately after brushing is when a cracked tile shows up, rather than a year later.
On site: Add 30 minutes
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.
What drives the price
Why chimney sweep quotes vary so much
- How many flues the chimney serves, and whether each needs doing
- Creosote stage — stage three is a different job, not a longer sweep
- Whether access is from the roof, and how steep that roof is
- Whether the appliance is an open fire, a stove, or a sealed insert
- Whether anything is nesting in there, which changes the visit
A standard annual sweep on a single open fireplace is a flat, modest price and includes the inspection. What changes the number is stage three creosote, a second flue, or a blockage that has to come out before brushing can start. Any of those get quoted before work begins rather than added at the end.

Common questions
How often should a chimney be swept?
Once a year is the standard, and NFPA 211 asks for an annual inspection whether or not you have used the fireplace. If you burn most nights through the winter, or you burn softwood or unseasoned logs, twice a season is more realistic — those produce creosote far faster than dry hardwood. A fireplace used a handful of times a year still needs the annual look, because nesting and masonry damage do not care how often you light it.
What is the difference between a chimney sweep and a chimney cleaning?
Nothing, in practice. They are two names for the same visit, and you can book either and get the same work. The trade calls it sweeping; most homeowners call it cleaning. What actually varies between companies is whether the visit includes an inspection and a camera scan of the flue, which is the part worth asking about before you book.
How much does a chimney sweep cost?
A standard annual sweep on one open fireplace is a flat modest price in most markets, and a good one includes the Level 1 inspection. Where it goes up is stage three glazed creosote, which needs chemical treatment or a rotary head and is a different job; a second flue in the same stack; or a blockage that has to be removed before a brush can pass. All three get quoted before anyone starts.
Will a chimney sweep make a mess?
It should not. The hearth gets sealed, a HEPA vacuum runs the whole time to hold the fireplace under negative pressure, and drop cloths go down over the floor. Soot in the room means the seal was not right. It is a fair thing to ask about when you book, and a fair thing to raise if it happens.
Do gas fireplaces need a chimney sweep?
They do not build creosote, so there is nothing to brush in the usual sense, but the venting still needs an annual check. Gas appliances vent into flues that block with nests and debris exactly like wood ones do, and a partially blocked gas vent produces carbon monoxide with no smoke to warn you. The visit is shorter, and skipping it is the more dangerous shortcut of the two.
