Chimney sweeping in Portland, with photos of your flue before and after
We sweep open fireplaces across the Portland metro with the room covered, a HEPA vacuum running and the flue brushed from the top or the bottom. Every sweep includes a Level 1 look-over and photos of your flue before and after.

What you are seeing
These are the signs Portland homeowners describe when they call about a sweep, often in the first cold week of fall.
- A sooty campfire smell from the fireplace on warm or rainy days, damper closed or not.
- Black flakes on the smoke shelf, the hearth or the firebox floor after a fire.
- Smoke that hangs in the room for the first few minutes before the fire catches.
- Soot on the glass doors, the mantel or the brick face above the opening.
- No record of the last sweep, or you bought the house and never had one done.
What we do on a sweep visit
A sweep runs in the same order every time, because the order is what keeps the soot out of your living room.
Cover the room and seal the opening
Canvas drop cloths go down from the door to the hearth. Glass doors come off, the grate comes out, and a dust panel seals the opening with the vacuum hose through it, so air moves into the firebox before the first rod goes up. We confirm the firebox is cold and ask where pets should be.
Pick the top or the bottom
We brush from the firebox up whenever the flue allows, which keeps the soot headed for the vacuum. We go up top when the damper frame, an offset or an old insert blocks the rods from below, or when the cap has to come off. A steep, wet or mossy roof gets a ladder plan first.
Brush the flue, the smoke chamber and the firebox
Rods go up with a brush sized to the flue, wire for clay tile and poly for a stainless liner, until the brush comes back clean. Then we scrape the corbelled brick of the smoke chamber, clear the smoke shelf of soot and leaves, brush the damper, and vacuum the firebox, ash dump and cleanout.
Look over the whole system, the Level 1 that comes with every sweep
A flashlight and mirror go up the clean flue, the damper is worked to check that it seats, and we check the firebrick and what else vents into the chimney. We look for the marks of a past chimney fire: puffy creosote, a warped damper, cracked tile. In the levels NFPA 211 defines, this is a Level 1: the readily accessible parts, no tools beyond a flashlight, not a camera scan.
Photograph the flue before and after
The camera goes up before the first pass and again after the last, aimed at the same tiles, so you see your own flue with the buildup and without it. Anything we flag gets its own photo: a cracked tile, an open joint, a nest on the smoke shelf. The set reaches your phone or email the same day.
Write down what we found
You get a short note before we leave: what degree of creosote came out, what the look-over showed, a date for the next sweep that fits how you burn, and one of three calls on the fireplace, ready to use, use after a named repair, or cold until a Level 2 camera inspection has seen it.
How we decide whether your flue needs sweeping
Your flue needs sweeping when the buildup reaches an eighth of an inch anywhere in it, the trade's working threshold, and we judge it with a flashlight, a mirror and a scrape of the tile, not by the calendar.
Creosote comes in three degrees. First degree is dry, flaky soot that brushes out. Second degree is crunchy and tar-flecked and takes a stiffer brush or a rotary head. Third degree is a shiny, hardened glaze that burns hot in a chimney fire, and it is a different job.
When the buildup is under that line, we say so, finish the look-over and the photos, and give you an honest date to check again.
Why spring and early summer are the Portland sweeping season
Book the sweep between March and early August, after the last fire of winter: the buildup comes out before it smells all summer, the calendar is open, and the Vaux's swifts have not yet moved into the city's chimneys.
Portland's airport averages close to 37 inches of rain a year and about an inch across July and August combined, so summer is when a damp smoke shelf dries and soot lifts off the tile. It is also when a neglected flue smells worst.
From mid-August to mid-October, migrating Vaux's swifts roost in masonry chimneys around the city; Chapman Elementary hosted the roost for about 40 years until 2024, and the birds now use other Portland chimneys. They are protected by federal law, so a flue with swifts in it waits, damper closed, until they leave.
What a sweep turns up in a 1900s to 1920s Portland chimney
More than a quarter of Portland's housing was built before 1940, and the brick chimneys of that era were often built without a clay tile liner, so the brush runs against bare brick and soft lime mortar.
Bare brick holds creosote in its joints and tired mortar sheds sand with each pass, so we use a softer head and photograph the joints instead of scrubbing them away. An unlined flue that still sees fires is a hazard the trade answers with a stainless liner sized to the fireplace.
The same stack may carry a second flue that once served a coal or oil furnace. When a high-efficiency furnace was vented out a side wall, that flue was left to a water heater alone, and it cools, condenses and crumbles from the inside; we look at it during the sweep.
What moves the price of a chimney sweep
The posted price covers a standard open fireplace with one flue, and these are the things that move it up, each one named before we start.
- Height and roof pitch: a three-story flue or a steep roof means more rods and a careful ladder setup.
- A second flue in the same chimney, for a second fireplace, a furnace or a water heater.
- Second-degree creosote that needs a rotary head and extra passes; third-degree glaze becomes creosote removal.
- Top access only, when a damper frame, an offset or an old insert blocks the rods from below.
- A cap that is seized, rusted or missing, if you want it replaced on the same visit.
Which sweep fits which fireplace or stove
An open fireplace is the standard sweep; stoves, inserts, pellet stoves and gas units each get their own visit, and this table says which to book.
| What you have | What the visit covers | Book this |
|---|---|---|
| Open masonry fireplace | Everything on this page | Chimney sweep |
| Factory-built fireplace in a chase | Metal flue brushed, refractory panels checked, chase cover looked at | Chimney sweep, say so when you book |
| Wood stove or insert | Connector pipe, baffle and liner; insert pulled if needed | Wood stove and insert sweep |
| Pellet stove | Burn pot, ash traps, heat exchanger, blowers and vent run | Pellet stove cleaning |
| Gas fireplace or insert | Vent inspection and service, no brush | Chimney inspection |
| Glazed creosote in any flue | Chemical treatment or rotary chain removal, no fires until it is out | Creosote removal |
When a repair stops making sense
A sweep stops making sense when the brush comes back glazed within a single season. That pattern means the fire, the wood or the flue itself is wrong, and a liner sized to the fireplace fixes more than another sweep will.
When the look-over shows cracked or missing tiles, a bare brick flue or open joints in the smoke chamber, the next step is a Level 2 camera inspection, then a liner, a parge or a rebuild, and the fireplace stays cold until that is settled.
Sweep: common questions
Will sweeping the chimney leave soot in my living room?
No, because the opening is sealed and the vacuum is running before the first brush goes in. Cloths cover the path from the door to the hearth, a dust panel closes the firebox, and the vacuum pulls room air inward. Tell us about pets or anyone sensitive to dust.
How often does an open fireplace in Portland need sweeping?
Once a year for a fireplace that gets regular use, and sooner whenever the buildup reaches an eighth of an inch. The national chimney standard calls for an inspection every year and cleaning as needed, so a fireplace that sees a handful of fires may be checked and not swept.
Is the Level 1 look-over with a sweep the same as a chimney inspection?
It is the first of three levels. Level 1 covers the parts we can reach without tools or a ladder, for a fireplace used as it always has been. A Level 2 adds a camera run of the whole flue and a written report, for a home sale, a new appliance or after a chimney fire.
When does a chimney sweep turn into a creosote removal job?
When the brush meets third-degree creosote, a shiny, hardened glaze that a standard brush slides over instead of lifting. Glaze needs a chemical modifier, a rotary chain tool, or both. We stop, show you the photos, and quote it as creosote removal, and no fires go in until it is out.
Can you sweep a chimney while Vaux's swifts are roosting in it?
No. Vaux's swifts are protected by federal law, so a flue with birds in it is left alone with the damper closed until they move on, and Portland's fall roosts run from mid-August to mid-October. We sweep after they go and fit a cap so the next flock picks a different chimney.
Does sweeping the chimney stop chimney fires?
It lowers the risk by removing the fuel a chimney fire burns; it does not make one impossible. A cracked tile, framing too close to the flue or wet wood can still cause trouble in a clean flue. If you hear a roar or see flames at the chimney top, get everyone out and call 911 first.
