Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Sweep Across New York City
A standard Chimney Sweep in New York City runs $220 – $380 for a single-flue cleaning, with two-flue rowhouse jobs typically landing between $350 and $550 before any repairs. Most sweeps here take 60 to 90 minutes once we’re on site. If you live in a pre-war brownstone or tenement, the job often involves an extra step few suburban sweeps ever touch: tracing your flue liner inside a shared chimney stack before the brush ever goes up. Call (336) 863-3889 and we’ll walk you through what your building actually needs, not what a generic checklist says.
Our crews know New York City’s buildings because we work in them every week. We’ve been up on rooflines from Stuyvesant Heights to Washington Heights, and we understand what the original mason who built your chimney in 1910 intended, and what a century of weather, coal exhaust, and renovation has done to it since.
Why Alcott Chimney Sweep Is New York City’s Preferred Chimney Sweep Company
Ruben Castellano founded Alcott Chimney Sweep in 2002 on a simple bet: homeowners will choose a chimney company that proves who it is before the truck arrives. Every technician we send to a New York City address is background-checked and identity-verified under the Threshold Standard, then announced to you by name and photo before we ring the bell. When our tech arrives in Bed-Stuy or Riverdale, they show a photo ID badge at the door. Every time. No exceptions. That’s not a courtesy; it’s the core of how we operate.
New York City homeowners call us because they’ve been burned by the alternative: a nameless subcontractor, a price that triples after the fireplace is opened, a “repair” nobody can verify. We don’t work that way. You get a written price before any work starts. You get a written guarantee on every repair, and if that repair fails, the second visit is free. That’s our 365-Day Done Right Promise, and it applies to every completed job in New York City.
This is also why our phones are answered by a live person 24/7. When smoke backs into a top-floor apartment on MacDonough Street at 11 p.m., there is no voicemail queue. A human picks up at (336) 863-3889.
Chimney Services in New York City
Chimney Services in New York City almost always start with the same discovery: the flue was built for coal, not for whatever is burning in it now. A routine sweep in this city frequently turns into a conversation about liner condition, mortar integrity, and whether the fireplace was ever meant to be reopened at all. That’s why our approach starts with a written scope and a camera inspection if the situation calls for it. You’ll see what we see before you approve a dollar of repair work. A standard cleaning and inspection typically runs $220 – $380 for one flue; a two-flue brownstone runs $350 – $550.
Creosote and Soot Removal
Creosote – the tar-like residue wood fires leave behind – builds fastest in the long, cool flues of New York City rowhouses. When a fireplace has been sealed for decades and then reopened after a Crown Heights gut-renovation, we often find a glaze that a brush alone cannot remove. We remove what’s there, document what remains, and tell you plainly if the chimney is safe to burn.
Annual Sweep Before Burn Season
New York City’s burn season runs roughly November through March, and the smart move is to schedule your sweep in September or October, before everyone else does. We book annually, we send the name and photo of your technician ahead, and we leave you with a written record of what was cleaned, what was found, and what to watch next year.

Chimney Sweep Certified in New York City
Chimney Sweep Certified work in New York City means more than brushing a flue. It means knowing what the Department of Buildings expects when a gas appliance vents through a chimney originally sized for a coal furnace. The original clay tile flues in pre-war tenements and rowhouses are often oversized for today’s gas boilers, and an unlined brick flue serving a gas appliance is a code-deficient condition. When our sweep uncovers that, we don’t just hand you a warning. We document it, explain what it means, and quote the liner installation that brings the building into compliance.
Level 1 and Level 2 Inspections
A Level 1 inspection is the visual check that accompanies every sweep: accessible portions of the flue, the chimney cap, the crown, the firebox. A Level 2 inspection goes further, with camera access, and is what we recommend whenever a property changes hands, a liner is suspected damaged, or a fireplace returns to use after being sealed. In New York City, where co-op boards routinely require inspection documentation before a sale closes, the Level 2 report is the document you actually need.
Liner Tracing in Gang Flues
The single most New York City-specific task we perform is tracing which flue liner belongs to which apartment in a shared chimney stack. One stack can carry four or five separate flues over one address, and getting the wrong one means cleaning a neighbor’s chimney while yours stays dirty. We verify the path before the brush goes up.
Trusted Brands We Service in New York City
We install and service DuraFlex stainless steel liner systems, HeatShield resurfacing, Gelco, Olympia Chimney, Famco, and Copperfield – the same trade materials specified by chimney professionals. When a brownstone on MacDonough Street needs a liner pulled and replaced, we’re not improvising with a box-store substitute. We stock the common liner diameters and cap sizes New York City rowhouses use, which means less wait time for parts and a faster turnaround on the repair itself.
Common Chimney Sweep Problems We See in New York City Homes
- Coal-era unlined flues. The original brick flues in 1880 – 1930 buildings were built for coal exhaust, not gas or wood. When we sweep them clean, the cleaning itself often reveals a DOB-filing condition the owner never knew existed.
- Freeze-thaw spalling above the roofline. New York City swings above and below freezing repeatedly from November to March, and the exposed brick chimney stacks above the rooflines of rowhouse neighborhoods pay for it. Crowns crack, mortar joints open, and water tracks into the gang flue.
- Third-degree creosote glaze reopened by renovation. Brownstone gut-renovations in Crown Heights, Bushwick, and central Harlem routinely uncover fireplaces sealed for 40 to 60 years. The creosote left inside has often hardened into a glaze that a brush cannot break, and it has to be chemically treated or the flue relined.
- Shared draft problems across apartments. In a gang flue system, a damaged liner on one apartment’s flue can pull smoke into a neighbor’s kitchen. We’ve been called to brownstones where the only visible symptom was backdraft in the wrong unit, and the actual problem was two floors down.

FAQs About Chimney Sweep in New York City
Yes, if the chimney still vents a gas boiler or water heater. New York City’s Department of Buildings requires correctly sized, properly lined flues for gas appliances, and a soot-choked or spalled flue venting gas is a carbon monoxide risk, not just a draft nuisance. We inspect the flue, camera it if it’s been more than a few years, and give you a written report that holds up with a co-op board or a DOB filing. Call (336) 863-3889 to schedule.
In a gang flue system, multiple apartments share one chimney stack but should have separate flue liners. If a liner on one flue has cracked or spalled away, the draft from a neighboring fireplace can pull smoke into the wrong apartment. We trace the liners, identify the damaged run, and repair or reline it so each unit drafts independently. This is the exact situation we’ve resolved in Bed-Stuy brownstones more times than we can count.
A quick look from the roofline usually tells us: clay tile liners terminate as a terra cotta ring or a few visible stacked tile sections, while a stainless liner shows a round metal tube rising above the crown, usually with a stainless cap attached. But the only way to know for certain – and to know the condition – is a Level 2 camera inspection. Many New York City owners find a stainless liner at the top that only covers a portion of the run, with original clay tile below it. We’ll show you the footage.
Third-degree creosote is the hard, tar-like glaze that forms when wood smoke condenses and bakes inside the flue over years of neglect – often decades when a fireplace sat sealed during a renovation. A standard brush glances off it. Removing it requires chemical treatment or mechanical methods that some flues cannot withstand, and in severe cases a liner replacement is the only safe answer. We’ll show you the camera image before recommending anything. Call (336) 863-3889 for a real assessment.
Yes. New York City’s coastal exposure means salt-laden air works on chimney caps, flashing, and fasteners year-round. Galvanized components corrode visibly within a few years, especially on rooftops exposed to harbor winds. We install stainless steel caps and flashing as standard on this market because it’s what survives. When we pull an old galvanized cap that’s rusted through after five years, the replacement we install is stainless.
