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

AfterFireplace Cleaning in New York, NY
Fireplace cleaning in New York typically costs between $150 and $350 for a standard wood-burning unit, and the work usually takes 45 to 90 minutes from setup to final vacuum. The price depends on how much creosote has built up, whether the firebox needs hand-scrubbing versus standard brushing, and how accessible your flue is from the roof or firebox. At Ashby Chimney New York, the price you’re quoted before we start is the price on your invoice, and every fireplace cleaning includes a written guarantee. Call (315) 644-2982 for a free estimate.
Fireplace cleaning is the part of Chimney Cleaning & Sweep in New York that zeroes in on the firebox itself: the floor and walls where your logs burn, the smoke shelf, the damper assembly, and the throat where the firebox narrows into the flue. A full chimney sweep addresses the entire venting system top to bottom. This service is for what you actually see and touch when you kneel down at the hearth. Ashby carries ash right in the name, which fits a trade where the day’s work is measured in soot, creosote flakes, and the fine gray dust that settles on mantels, screens, and surrounding floors.
Our crew is led by Nathan Corliss, and every technician on the job is background-checked and uniformed. You’ll know exactly who’s walking into your home before they ring the bell. New York fireplaces earn their grime honestly: hard winters, soft woods, occasional burning of whatever the last owner left in the garage. We’ve cleaned fireboxes in brownstones on the Upper West Side, prewar co-ops in Forest Hills, and brick colonials out in Riverdale, and the residue tells a story every time.
When You Need Fireplace Cleaning
Most New York homeowners need a fireplace cleaning once a year if they burn regularly, or every other year if the fireplace is used for occasional ambiance. But there are specific signs that tell you it’s time now, not next season. These are the ones we hear about most on the phone:
- You smell smoke or a sour, charred odor even when the fireplace is cold. That smell is creosote and old soot releasing into the room, often worse on humid summer days when the air pushes downward through the chimney. In New York’s humid July and August, a dirty firebox can make a whole living room smell like last winter’s fires.
- Black, shiny or flaky buildup covers the firebox walls. Stage one creosote is dusty and brushes away easily. Stage two looks like dark, crusted flakes. Stage three is glossy and tar-like. If you can scrape a shiny layer off the firebrick with a fingernail, that’s stage two or three, and it’s time to call us.
- Your damper won’t open fully or closes stiffly. Soot, rust, and creosote collect on the damper plate and hinges. Left too long, a sticky damper can warp or seize entirely, which turns a $200 cleaning into a $400 damper repair. We see this in older New York homes where dampers are original to 1920s and 1930s construction.
- Fires are harder to start and smoke spills into the room instead of rising. A clogged throat or smoke shelf restricts draft. The fire struggles, the room gets hazy, and your smoke detectors earn their batteries. If you’re cracking a window in February just to keep the living room breathable, the fireplace needs attention.
- You just bought the home, and you don’t know when it was last cleaned. Prewar co-ops and older New York houses change hands with fireplaces that have been neglected for years. A cleaning during escrow or in the first winter is cheap insurance against discovering a hidden problem on the first cold night.
- You see soot stains on the mantel, wall above the fireplace, or the ceiling nearby. That staining means smoke is escaping the firebox during normal use, often because the upper firebox and smoke chamber are caked with residue that narrows the passage. The stain is the symptom; the buildup is the cause.
None of these conditions fix themselves. Soot hardens. Creosote compresses into tar. The damper seizes a little more each time you use it. And in New York, where the heating season can stretch from October through April, a fireplace that isn’t clean costs more to use because the draft weakens and the heat output drops.
Our Fireplace Cleaning Process
We follow the same order of operations on every job, whether it’s a marble-faced fireplace in a Gramercy Park co-op or a stone hearth in a Staten Island split-level. The process doesn’t change because the building does. Here’s what happens when you book a fireplace cleaning with Ashby Chimney New York:
- Arrival and setup. A uniformed technician arrives in the scheduled window, not three hours later. We lay drop cloths from your entry to the hearth, set up a HEPA-filtered vacuum, and seal the firebox opening with a fitted barrier before any brushing starts. Your rugs, furniture, and air stay clean while we work.
- Firebox inspection. Before we clean, we look. Cracked firebrick, loose mortar joints, a warped damper, rust on the lintel bar: these go in our written report with a repair recommendation if needed. We don’t sell you a repair while we’re standing at the door; we show you what we found and quote a written price before anything extra is done.
- Hand-scrubbing the firebox. The firebox walls and floor get scraped and wire-brushed with a technician down at hearth level, not just swept from above. This is where fireplace cleaning differs from a standard sweep. We remove the hard, baked-on creosote that a brush through the flue never touches.
- Smoke shelf and damper cleaning. The smoke shelf, that flat ledge behind the damper where soot piles up like snowdrift, is hand-cleaned and vacuumed. The damper gets scraped, lubricated where needed, and tested. In New York’s older buildings, this is often the first time the smoke shelf has been touched in decades.
- Flue brushing. Once the firebox is clean, we extend the cleaning up through the throat and into the flue liner, sweeping the full run of the chimney. This clears the venting path while the vacuum keeps everything moving out of your living space, not into it.
- Final vacuum and cleanup. We remove the barrier, vacuum the firebox, wipe down the damper handle and surrounding hearth, and haul the soot out with us. The fireplace is ready to use, and you get a written report describing what we found and what we did.
Most jobs take under two hours. If we find something that needs repair, we photograph it, explain it in plain English, and quote a written price. You decide. That’s the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails.
Fireplace Cleaning Pricing in New York
Here’s the honest truth about what fireplace cleaning costs in New York. The range is wider here than in most markets because the housing stock is so varied. A standard single-flue wood fireplace cleaning runs between $150 and $250. Add a second flue or a heavily creosoted firebox needing extended hand-scrubbing, and you’re looking at $250 to $350. Gas fireplace cleaning, which involves removing and cleaning the log set, checking the gas valve, and brushing the venting, runs $200 to $400 depending on the vent configuration.
What affects the price is never a mystery. You’ll know before we start:
- Access. If the roof access is straightforward and the fireplace is on the first floor, the price is at the low end. Rooftop work on a five-story brownstone or a steep-pitched roof in Riverdale adds time and safety equipment.
- Creosote stage. Stage one creosote brushes off quickly. Stage three, the tar-like coating that forms from burning soft, unseasoned wood, requires scraping and chemical treatment. It takes longer and costs more. In New York, soft woods like pine and hemlock sold at corner bodegas often produce exactly this kind of hard creosote.
- Damper condition. A damper that’s heavily rusted but still functional takes extra time to clean and lubricate. A damper that’s too far gone needs replacement, which we quote separately before doing the work.
- Soot volume and splatter. Some fireplaces have years of layered soot. Extended hand-scrubbing and multiple vacuum passes are priced accordingly, and we tell you upfront.
Every job gets a written price before any work starts. The number on the invoice matches the number we quoted at the door. Every cleaning includes a written guarantee, and if something isn’t done right, the 365-Day Done Right Promise means we make it right. A free second visit if the repair fails, inside the guarantee period, is part of how we work. Not an add-on. Standard.

FAQs – Fireplace Cleaning
How much does fireplace cleaning cost in New York?
Fireplace cleaning in New York typically costs $150 to $350 for a wood-burning unit, with gas fireplace cleaning running $200 to $400. The range depends on how much creosote has built up, access to your flue, and whether the smoke shelf and damper need extended hand-cleaning. Our written quote is free, and the price is locked before we touch the fireplace. Call (315) 644-2982 to get an exact number for your home.
Can you clean my fireplace the same day?
In many cases, yes, we can have a technician at your door same day or next day, depending on the schedule and your neighborhood. New York boroughs from Manhattan to the Bronx are in our regular service area, and we keep our calendar built around real arrival windows, not four-hour gaps. Call (315) 644-2982 and a live person will tell you exactly when we can be there.
Is it cheaper to clean the fireplace or replace it?
Cleaning is almost always cheaper, and it’s the right first step. A standard cleaning costs $150 to $350, while replacing a firebox or relining a chimney can run into the thousands. The exception is when hidden damage has already gone past the point of repair, which is exactly why we inspect what we’re cleaning and give you a straight answer with photos. You’ll know what’s clean, what’s deteriorating, and what can wait.
Does fireplace cleaning make a mess in my home?
No. We seal the firebox with a fitted barrier, run a HEPA-filtered vacuum throughout the job, and lay drop cloths from your entry to the hearth. The technique is designed so that soot leaves through the vacuum, not into your living room. After we finish, the damper handle, hearth, and surrounding floor are wiped down, and the soot goes out with us. Your home is cleaner than when we arrived.
