Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterAnnual Sweep in New York, NY
An annual chimney sweep in New York City typically costs between $189 and $329 for a standard fireplace with a single flue, and most sweeps take 60 to 90 minutes from setup to final vacuum pass. You should have your chimney swept once a year if you burn wood more than a dozen times per season, or sooner if you notice a campfire smell indoors, smoke backing into the room, or dark glaze building up on the firebox walls. Ashby Chimney New York has done this work since 2002, and every sweep comes with a written price before we start and a written guarantee when we finish.
This page covers the annual sweep service specifically. For the full range of what we clean and how we clean it, see our Chimney Cleaning & Sweep in New York page. If you want the short version: creosote builds up every time you burn wood, creosote catches fire, and a yearly sweep is the cheapest way to make sure it doesn’t. Call (315) 644-2982 and we’ll get you on the schedule.
Ashby carries ash right in the name. Fitting, since our job is to haul it out of your flue before it becomes a problem.
When You Need Annual Sweep
New York winters push fireplaces hard. We run stoves and inserts for months at a stretch, often with wood that’s been sitting in a backyard pile through a humid summer. That combination produces creosote faster than most people expect. Here’s what tells you it’s time for a sweep:
- You’ve burned a full cord or more this season. A cord of mixed hardwood leaves behind roughly one to two gallons of creosote in a typical masonry flue. In older Manhattan brownstones and Queens brick colonials with unlined chimneys, the buildup tends to run heavier.
- You smell smoke or a stale campfire odor indoors after the fire’s been out for a day or more. That smell means combustion gases are drifting back down the flue. It’s often a creosote restriction, and it won’t fix itself.
- You see dark, shiny glaze on the firebox interior or visible soot fall into the room. Shiny, tar-like creosote is the type that ignites most readily. If you tap the flue wall with a fire poker and black flakes rain down, you’re past due.
- Your fire struggles to draw even with the damper fully open. Restricted airflow from creosote buildup makes fires lazy, smoky, and inefficient. You’re burning more wood to get less heat.
- You bought a home in New York and inherited a fireplace you’ve never had inspected. Plenty of prior owners cleaned out the firebox before showings but never touched the flue. If there’s no service record, assume the chimney needs work.
- Your last sweep was more than 12 months ago. This one’s simple. The National Fire Protection Association standard on chimneys calls for an annual inspection and sweep as needed. We treat “as needed” as a conservative yes for anyone who actually burns wood.
In neighborhoods like Park Slope, Riverdale, and Forest Hills, we regularly pull more creosote from chimneys that were “just cleaned last year” than homeowners expect. Wet firewood, poor draft, and short burn cycles all accelerate the accumulation. If any of the above sounds familiar, schedule a sweep rather than waiting for a problem to show up with smoke in the living room.
Our Annual Sweep Process
There’s no mystery to what we’re doing, and we’re happy to show you the work before and after. Here’s how a standard annual sweep goes with Ashby Chimney New York:
- Protect the room first. We lay drop cloths from the front door to the hearth, cover the immediate hearth area with a second layer, and seal off the fireplace opening. Our technicians are background-checked and uniformed, and they’ll introduce themselves by name before anything comes off the van.
- Inspect the flue before we touch a brush. We run a camera or a powerful flashlight up the flue to identify the liner type (clay tile, stainless, or unlined masonry), check for blockages, and note any cracking, spalling, or previous repair work. It’s better to know what we’re working with before the brush hits it.
- Sweep from the top down with properly sized brushes. We typically access the flue from the roof, using poly or steel brushes matched to the flue dimensions. We remove creosote, soot, and any debris like bird nests, leaves, or squirrel stashes that accumulated since the last sweep.
- Clean the firebox, damper, and smoke shelf. The brush only reaches so far. We hand-clean the firebox floor, the damper assembly, and the smoke shelf where debris collects. Most sweeps miss the smoke shelf; we don’t.
- Run a final camera or visual check. After the sweep, we look again. If we find damage that wasn’t visible behind the creosote (a cracked flue tile, a failing mortar joint, a liner that’s delaminated), we’ll show you photos and give you a written price for repair. No pressure, no surprises.
- Clean up and put it in writing. We vacuum the firebox, wipe down the hearth, and remove every drop cloth. You get a written report of what we found and did, plus our written guarantee. The guarantee is ours to give, not something you pay extra for.
Every sweep includes this full process. We don’t sell a cheaper “brush-only” option that skips the firebox or the camera check, and we don’t upsell you on a “chimney tune-up package” that should have been part of the job in the first place.
Annual Sweep Pricing in New York
We say the price before we start because that’s how we’d want to be treated. It’s the first rule of what we call The Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, and come back if it fails.
Here’s what a standard annual sweep typically costs in New York depending on what you’ve got:
| Service Type | Typical Price Range |
|---|---|
| Standard fireplace sweep (masonry chimney, 1 flue) | $189 – $269 |
| Wood stove or insert sweep (with pipe removal as needed) | $229 – $329 |
| Two-flue chimney (e.g. fireplace plus furnace flue) | $299 – $429 |
| Heavy creosote removal (glazed/stage 3 buildup) | $329 – $499 |
| Level 1 chimney inspection (add-on during sweep) | $75 – $125 |
What moves the price around in New York specifically:
- Roof access difficulty. A steep-pitch roof in Riverdale with a four-story drop takes longer to navigate safely than a walkable flat roof on a Brooklyn rowhouse. We don’t cut corners on roof safety, and the price reflects the time.
- Creosote stage. Stage 1 and 2 creosote (flaky, dusty, or granular) brushes out cleanly with standard equipment. Stage 3 glazed creosote requires chemical treatment or rotary cleaning heads, which adds labor and material cost.
- Flue length and construction. A 35-foot flue in a prewar building is a different job than a 15-foot flue in a newer colonial. Unlined chimneys need gentler handling. Previously repaired chimneys need more careful inspection.
- Blockages found on site. Nests, dead birds, and debris removal take extra time. We’ll tell you the added cost before we start removing anything, and it’s always in writing.
Every job gets a written price before any work starts. The number on that paper is the number you’ll see on the invoice. If we find something inside the chimney that changes the scope, we stop, we show you, and we agree on a new written price before we continue. That’s the Kingswell Guarantee, and it’s been our rule since 2002.
Your annual sweep also includes the 365-Day Done Right Promise: if it’s not done right, we make it right, free of charge, inside the guarantee period. If you find creosote we missed, or a problem surfaces that we should have caught, we return at no cost and put it straight.
Not sure which service tier applies to you? Call (315) 644-2982 and describe your fireplace or stove. We’ll give you an honest price range over the phone, not a “come out and we’ll see” runaround.
Why New York Homeowners Book With Ashby
We know the history. Most of our customers in New York have a story about a chimney company that didn’t show, or a “cheap clean” that turned into a $1,400 emergency repair, or a technician who left soot footprints across the living room rug. Nathan Corliss started this business because he kept hearing those stories and knew the work could be done better. No gimmicks. Just a clean flue, a straight price, and a written promise behind it.
The Kingswell Guarantee is not a marketing line. It’s the operating standard for every Ashby location, including ours in New York. Each Ashby location is independently owned and operated under the Kingswell Guarantee, so when you call our New York office, you’re dealing with the people who own the trucks, answer the phones, and show up at your door.
When repairs come out of a sweep (and they sometimes do, especially in older New York homes), we use professional-grade materials from recognized chimney-trade brands: DuraFlex stainless liners, Olympia Chimney caps and components, and Copperfield termination products. These are the same materials specified by licensed chimney professionals and code inspectors. We don’t patch with hardware-store caulk and call it fixed. A material can mean the difference between a liner that lasts 15 years and one that fails in two.
We also answer the phone. A live person, 24 hours a day, 7 days a week. When you call at 8:30 PM on a Tuesday because smoke backed into the house, you’ll get a human on the line, not a voicemail loop that promises a callback in “one to two business days.” The number is (315) 644-2982.

FAQs – Annual Sweep
How much does an annual chimney sweep cost in New York?
An annual sweep for a standard fireplace in New York typically costs between $189 and $269 when the flue is accessible and creosote is at normal levels. Wood stoves and inserts run $229 to $329, and heavy glazed creosote removal can reach $499. Ashby Chimney New York puts every price in writing before any work begins, and estimates are always free. Call (315) 644-2982 for an exact quote based on your fireplace.
Can you sweep my chimney today?
In most weeks, yes, we keep same-day and next-day slots available for New York customers, and our phones are answered by a live person 24/7. During peak fall and early winter weeks, same-day service is not always possible, but we’ll give you a straight answer and a specific arrival window when we book. Call (315) 644-2982 to check today’s availability.
How often should I really sweep my chimney in New York?
If you burn wood regularly through a New York winter, once a year is the practical minimum, and some heavy-use households in older homes benefit from a sweep every 7 to 8 months. The National Fire Protection Association recommends an annual inspection and cleaning as needed, and in our experience “as needed” means yearly for anyone burning more than a face cord per season. Ashby Chimney New York will tell you honestly whether your chimney needs attention or can wait another season.
What’s included in your annual sweep service?
Our annual sweep includes full flue brushing, firebox and damper cleaning, smoke shelf debris removal, a before-and-after visual inspection, and a written report of findings and condition. We also provide a written guarantee on every sweep through the Kingswell Guarantee. If anything isn’t done right, we return and fix it at no charge inside the guarantee period. It’s the same process on every job, no short versions and no add-on fees for things that should already be covered.
Will an annual sweep prevent chimney fires?
Yes, a properly performed annual sweep removes the creosote that causes most chimney fires, and that’s the single most effective preventive step a homeowner can take. That said, no sweep can prevent fires caused by improper burning practices (like burning green wood or restricting airflow), so we’ll also tell you what you can do between sweeps. In New York, where firewood quality varies widely and urban lots make seasoned wood storage hard, we see both sides of the problem regularly. Call (315) 644-2982 to schedule a sweep or ask us about your wood supply and burning habits.
Is it cheaper to skip a year if I don’t burn much?
It can be, and we’ll say so plainly. If you burn fewer than a half-dozen fires per year, haven’t noticed any smell or draft problems, and had a clean bill of health last year, skipping a season is a reasonable call. The important caveat: even occasional fires produce creosote, and in humid New York summers that creosote can absorb moisture and accelerate flue deterioration. When in doubt, call us at (315) 644-2982 and describe your usage. We’ll tell you honestly whether it’s time or not.
