Chimney Sweep in New York - One Flat Price, You See What We See

Trusted Chimney Sweep for New York Homeowners

A chimney sweep in New York typically costs between $189 and $349 for a standard fireplace, depending on the flue type, the height of the roofline, and how much creosote has built up since the last cleaning. Most sweeps in the five boroughs take 60 to 90 minutes from setup to final vacuum, and at Ashby Chimney New York we show up with a written price before any work starts, so the number you approve is the number you pay. Nathan Corliss has run this shop since 2002 under the Kingswell Guarantee, and the promise is simple: say the price, show up in the window, leave it cleaner than we found it, put the guarantee in writing, and come back if the repair fails.

Chimney Sweep Services

Chimney Sweep Services cover the full scope of what a dirty or obstructed flue demands: removing creosote and soot from the firebox to the cap, clearing blockages like bird nests and fallen brick, and checking the liner for cracks while we’re already in there. You need this when smoke rolls back into the living room, when there’s a sour campfire smell even with the damper closed, or when it has been more than a year since anyone looked at the flue. Ashby Chimney New York does the work with professional-grade rotary brushes and a HEPA vacuum that keeps soot inside the machine, not on your rugs, and most New York sweeps run $189 to $349 depending on flue height and buildup.

Standard Fireplace Sweep

We sweep the full flue from firebox to chimney cap, removing creosote, soot, and the odd tennis ball that found its way down from a roof deck. Before we leave, we run a camera up the flue so you can see the result on our screen, not just take our word for it.

Blockage and Debris Removal

New York chimneys collect more than creosote. Pigeons, squirrels, and a surprising number of takeout lids end up above the damper, and a blocked flue pushes carbon monoxide back into the home. We pull the obstruction, sweep the flue, and note whether the cap needs replacement.

Chimney Cleaning

Chimney Cleaning is the physical removal of creosote, soot, and combustion residue from the flue liner (the clay or steel tube that vents combustion gases out of your home), the smoke chamber, and the firebox. It is the single most effective thing a homeowner can do to prevent a chimney fire, and in New York’s older housing stock, where some flues have been in service since the 1920s and 1930s, annual cleaning is not a suggestion. Ashby Chimney New York charges between $189 and $349 for a standard cleaning, with the final number set in writing before we touch a brush, and we use rotary whip systems sized to the liner so the clay tiles don’t get scored.

Creosote Removal by Flue Type

Glazed creosote, the hard, shiny residue from low-temperature fires, needs more than a wire brush. We assess the stage of buildup during the estimate and match our tools to the liner, whether you have a clay tile flue in a prewar brownstone or a steel liner in a newer build.

Smoke Chamber and Damper Cleaning

The smoke chamber is the often-forgotten bottleneck above the firebox where soot packs into angled brick. We clean it with the same care as the flue itself, because that shelf of debris is where chimney fires start in New York homes.

Fireplace Cleaning

Fireplace Cleaning covers the firebox, grate, glass doors, and the surrounding hearth face, not just the flue above it. This is the service you want when last winter’s ash has hardened into a gray crust, when the glass has gone smoky and streaked, or when you are preparing a rental unit in Murray Hill or Morningside Heights for the next tenant. We remove the ash with a dedicated vacuum, clean the firebrick with masonry-safe solutions, and leave the hearth ready for the season. Expect to pay $189 to $349 for a full fireplace and flue cleaning in New York, with the same written-price rule as every Ashby job.

Firebox and Grate Restoration

Built-up ash holds moisture, and moisture attacks the mortar joints in your firebox. We clear the residue, inspect the refractory panels, and tell you honestly whether the firebox can wait another year or needs attention now.

Glass Door and Screen Cleaning

Glass doors fog with a film that ordinary glass cleaner cannot cut. We use a ceramic-glass cleaner formulated for fireplace temperatures, and we check the door seals so smoke stays in the firebox where it belongs.

Chimney Services

Chimney Services at Ashby Chimney New York go beyond the sweep to include inspections, minor masonry pointing, cap and screen replacement, and liner assessments, all under one roof and one written guarantee. You might call us for a sweep and learn that the real issue is a cracked flue liner or a rusted damper assembly, and because we carry materials from recognized chimney-trade brands, the fix can often happen the same week. Our standard sweep runs $189 to $349, and if the inspection turns up something bigger, the repair quote comes in writing before anything proceeds, with no surprise line items.

Level 1 and Level 2 Inspections

A Level 1 inspection is a visual check of the accessible chimney, done during a standard sweep. A Level 2 inspection adds a camera run through the full flue, which we recommend when you buy a home, after a chimney fire, or after any structural change to the roof.

Cap, Crown, and Chase Cover Work

Water is the great enemy of New York chimneys, and the cap and crown are the first line of defense. We replace rusted caps, repair cracked crowned mortar, and seal exposed brick with breathable waterproofing rated for the Northeast’s freeze-thaw cycles.

Chimney Sweep Certified

Chimney Sweep Certified means the technician in your home has passed recognized industry training in flue dynamics, code compliance, and fire safety, and carries the credentials to handle your specific system. Certification matters in a city like New York, where prewar masonry, mid-century steel liners, and modern prefab fireplaces all sit side by side, sometimes in the same building. Ashby Chimney New York only sends background-checked, uniformed technicians into your home, led by Nathan Corliss, who has been at this since 2002. The sweep itself runs $189 to $349, and the certification behind it costs you nothing extra.

Training That Shows Up on the Job

A certified sweep knows the difference between a cool-running prefab fireplace that needs a light brush and a 90-year-old masonry flue that needs a rotary whip. That knowledge is why we can quote a flat price at the door instead of an estimate that doubles once we’re on the roof.

Paperwork and Parity

If your co-op board or insurance carrier asks for proof the chimney was swept by a qualified professional, we provide the documentation. Written record of the sweep, the condition of the flue, and any photos from the camera inspection go with you after we finish.

Gas Fireplace Cleaning

Gas Fireplace Cleaning is the service for vented and ventless gas units that have developed a film of white soot on the glass, logs that look fuzzy with dust, or a burner that no longer produces a clean blue flame. A gas fireplace does not make creosote like a wood fire, but it still needs annual attention because dust, pet hair, and the byproducts of combustion clog burner ports and coat the firebox. Ashby Chimney New York services gas units across New York, from the converted parlors of Brooklyn Heights to newer builds in Greenpoint, and the cleaning typically runs $189 to $349 depending on the unit.

Burner and Pilot Assembly Cleaning

We disassemble the burner tray, clean each port, and inspect the thermocouple and pilot assembly for wear. A lazy, orange flame is a sign of clogged ports, not a charming aesthetic, and it means incomplete combustion is sending more carbon monoxide into the room than it should.

Log Set and Glass Media Care

Ceramic logs and fire glass need gentle handling, not a shop vac set on a stone surface. We use low-pressure air and soft brushes to clean the media, and we reset the logs exactly per the manufacturer’s pattern so the flame picture stays correct.

Chimney Maintenance

Chimney Maintenance is the ongoing work that keeps an annual sweep from becoming a five-figure liner replacement: seasonal checks, moisture control, small pointing repairs, and replacing cheap components before they fail. New York’s weather cycles freeze and thaw brick dozens of times a year, and every cycle works on the mortar joints like a chisel. Ashby Chimney New York recommends an annual sweep and inspection, which runs $189 to $349, and we tell you plainly when something can wait another year versus when deferring it will cost triple down the road.

Seasonal Pre-Burn Check

Before the first fire of October, have the flue looked at. A visual check of the cap, damper, and firebox catches the problems summer left behind, like a bird’s nest from June or a crack that opened in the July heat.

Moisture Management and Flash Point Repairs

Water intrusion through failing flashing is the leading cause of masonry deterioration on New York rooflines. We inspect the flashing where the chimney meets the roof deck and seal it with a high-grade silicone or urethane sealant, not a tube of caulk from the hardware store.

Brands We Service

We’ve worked on Olympia Chimney caps and chase covers for years, and we stock their common replacement parts, so a rusted cap on a Brooklyn Heights brownstone doesn’t have to wait on a special order. Their stainless steel assemblies hold up well against salt air and hard winters, but no cap lasts forever, and we know which model fits your flue size without guessing.

Most mid-century and modern steel liners in New York come from DuraFlex, and we’ve installed and swept enough of them to know their failure patterns, particularly at the tee and the cap connection. We also service Famco dampers and Copperfield chase covers, with the same rule for every brand: whether you have Olympia Chimney, DuraFlex, Famco, Copperfield, or any other make, we can help.

Signs You Need a Pro Right Now

• Smoke rolls back into the room instead of up the flue. This tells you the draft path is blocked, either by creosote, a nest, or a closed damper you cannot see. Smoke in the living room also means carbon monoxide is in the breathing air, and that is a call-us-today situation.
• A sour, campfire-like smell lingers even with the fireplace cold. Creosote absorbs moisture and off-gasses on humid New York days. The smell is not nostalgia; it is fuel coating your flue walls, waiting for a spark.
• You hear scratching, flapping, or chirping from the chimney. Birds and squirrels use uncapped flues as summer homes in the boroughs. A blocked flue plus a lit fire equals smoke and carbon monoxide pushed back into every floor of the house.
• White staining appears on the exterior brick. That is efflorescence, salt pushed out of the masonry by water moving through the brick. It means moisture is getting in somewhere, and the freeze-thaw cycle will turn that moisture into spalled brick faces.
• It has been more than a year since the last sweep. The National Fire Protection Association’s standard, NFPA 211, calls for annual inspection and cleaning as needed. In New York, where many homes burn pressed logs and scrap wood, annual sweeping is the floor, not the ceiling.

Our Process, Step by Step

1. 1
   You call, a person answers. No voicemail loops. Tell us about your fireplace, your building type, and the last time anyone swept the flue, and we book a window that works for you, including evenings and weekends.
2. 2
   We arrive in the window and walk the job. The technician looks at the firebox, the damper, the cap, and the accessible roofline, then puts the flat price in writing before any work starts. You approve the number, or we shake hands and leave with no charge.
3. 3
   We sweep the full flue with a rotary system. Brushes sized to your liner spin through the flue, knocking creosote loose while a HEPA vacuum runs at the firebox to keep soot out of your home. Drop cloths go down before the first tool comes out.
4. 4
   We run a camera inspection. After the sweep, the technician sends a camera up the flue and you watch the screen. If there is a crack, a failing joint, or a nest we missed, you see it with your own eyes, and we quote the repair in writing.
5. 5
   We leave it cleaner and put the guarantee in writing. Your receipt includes the price, the work performed, the camera findings, and the written guarantee on any repair we made. If a covered repair fails within the guarantee period, we come back and fix it at no charge.
