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 Cleaning & Sweep Across East Harlem
Chimney cleaning in East Harlem runs $189-$389 for a standard sweep, and a Level 2 camera inspection adds $149-$249 depending on the flue count and rooftop access. Most East Harlem jobs take 60-90 minutes once we’re on the roof. If you live in a pre-war tenement or brownstone between 96th and 125th Street, the chimney you’re heating with was probably built before your grandparents were born, and it needs a different kind of attention than a suburban fireplace. Call (516) 301-1549 and you’ll get a written price before anyone touches a brush.
Why Level Two Chimney Astoria Is East Harlem’s Preferred Chimney Cleaning & Sweep Company
East Harlem’s chimney stacks are not like the ones in Astoria or Long Island City. They’re older, taller, and shared. A single brick stack on East 110th Street might vent four apartments, a basement boiler, and a long-sealed fireplace all at once. We’ve worked on enough of them through our East Harlem Fireplace Services to know what that means before we climb the ladder.
Our Chimney Cleaning & Sweep crews arrive with a camera system that goes down the flue on every single job. Not a flashlight. A camera. You see what we see, on our screen or yours, before you spend a dollar on repairs. That’s Clause 4 of the Haven Standard, and we’ve done it that way since 2009, through more than 38,000 inspections and cleanings.
Corrine Halstead leads our New York City operation, and every tech who shows up at your building is background-checked, uniformed, and assigned to your job by name. You get a text when they’re on the way. You get a written scope, a written price, and a written warranty before work starts. You get a photo record when we’re done. If anything isn’t done right, the 365-Day Done Right Promise means we come back and make it right.
Our Chimney Cleaning & Sweep Services in East Harlem
Level 2 Inspection
In East Harlem, a Level 2 inspection is not an upgrade. It’s the baseline for any chimney that’s been converted, sealed, shared, or untouched for more than a year. We run a CCTV camera down the full flue and record what it sees: liner cracks, collapsed clay tiles, creosote glazing, dead pigeons, the works. You get the footage. If you’re buying or selling a co-op, your board will ask for exactly this. If you’re a landlord, it’s the document that protects you when a tenant says they smelled exhaust.
Creosote Removal
Creosote is not one thing. First-degree creosote brushes off. Third-degree creosote is a hard, shiny glaze that lines the flue like tar and burns like fuel. East Harlem’s pre-war stacks are prone to it because gas boilers venting through old coal flues create exactly the cool, slow-moving exhaust conditions creosote loves. We remove it with rotary chains and chemical treatments rated for the material, and we never run a steel brush through a clay-tile flue without checking its condition first. Rushing that step knocks loose deteriorated mortar and can accelerate a collapse.
Annual Sweep
East Harlem buildings with active fireplaces should be swept every year, and buildings with gas appliances venting through masonry chimneys should be inspected on the same schedule. An annual sweep is the cheapest insurance you’ll buy this year. It catches the blocked flue before it becomes a carbon monoxide event on the top floor, and it catches the spalling brick before a chunk lands on someone’s roof deck.
Soot Removal
Soot is softer than creosote and easier to remove, but in an East Harlem walk-up it often appears alongside its nastier cousin, especially in flues that share space with boiler exhaust. We remove both, then camera-scan the flue to confirm nothing was left behind. You’ll see the before and after.

AfterTrusted Brands We Service in East Harlem
When a chimney in East Harlem needs a liner rather than a sweep, we source materials from manufacturers we trust: DuraFlex for stainless steel liners, HeatShield for resurfacing damaged clay tile, and Gelco for caps and crowns. These are not names we picked from a catalog. They’re what we install when the camera shows the old liner is gone. We keep common parts staged at our New York City office so an East Harlem job doesn’t wait a week for a four-dollar rain cap.
Common Chimney Cleaning & Sweep Problems We See in East Harlem Homes
- Crumbling clay tile liners. East Harlem’s tenements were built with terra cotta flue liners that are now 80 to 120 years old. Freeze-thaw cycles near the Harlem River and East River have cracked them, and the pieces land in the smoke chamber or jam the flue.
- Sealed fireplaces reopened during gut renovations. Renovation crews knock out a wall, find the old fireplace, and light a fire without checking the flue. What’s behind the plaster is often decades of pigeon nesting, soot collapse from neighboring units, and a flue that was never designed for open burning.
- Boiler exhaust vented into coal-era flues. The original chimney served coal ranges. Someone connected a gas boiler to it without relining. The flue is oversized, the exhaust cools too fast, and the building gets carbon monoxide drifting back into apartments on the upper floors.
- Rooftop crown failure. East Harlem weather beats on exposed chimney tops. Missing mortar joints and spalling brick let water into the shared stack, which freezes, expands, and breaks the flue from the inside out.
Pricing for Chimney Cleaning & Sweep in East Harlem, NY
Here’s what we actually charge in East Harlem. A standard sweep of a single fireplace or boiler flue runs $189-$289. A sweep plus Level 1 inspection is $249-$349. A Level 2 camera inspection alone is $149-$249, and if we’re already on the roof for a sweep, adding the camera is usually at the lower end of that range. Creosote removal of third-degree glaze adds $75-$150 per hour depending on how bad the flue is. Rooftop access on a six-story walk-up with a bulkhead ladder adds $40-$75. Every price is written down before we start. You agree to a number, not a guess. Call (516) 301-1549 and we’ll give you a real quote, not a “call for pricing” runaround. If you already have a written estimate from another company, bring it. We’ll give you a free second opinion on it.
Why East Harlem’s Pre-War Tenements Need Camera Inspection, Not Just a Sweep
Here’s what makes East Harlem different from anywhere else in the city. The neighborhood’s residential fabric is dominated by brick tenements built between the 1890s and the 1930s. Those buildings have multi-flue chimney stacks that originally vented coal ranges and individual apartment fireplaces. When coal went out and gas boilers came in, the flues were converted, often without proper relining. A chimney stack on a five-story walk-up on East 112th Street might now vent four apartments and a basement boiler through clay tiles that were sized for coal smoke a century ago.
Crumbling mortar joints and unlined flues in that setup don’t create a single-household problem. They create a building-wide carbon monoxide risk that crosses every occupied floor. A sweep alone can’t find a collapsed liner or a hidden blockage from a sealed fireplace on the third floor. Only a camera can. That’s why we don’t do “just a sweep” in East Harlem. We do a sweep plus a look inside, every time, and we show you the footage before we recommend anything.
We were on a five-story walk-up on East 112th Street between Lexington and Park Avenues a few years back, called in because tenants on the top floor smelled exhaust. Our camera found third-degree creosote glazing the flue that once served a coal stove, plus a clay tile liner that had collapsed into the shared stack. We removed the debris, documented everything with CCTV footage, and recommended a DuraFlex stainless steel liner. No upselling. The landlord looked at the images on our screen and made the call in ten minutes. That’s how it should work.
Many East Harlem tenements also have fireplaces that were sealed or plastered over during the rent-stabilized era, decades ago. When units turn over or a landlord guts the place, the fireplace comes back, and someone lights a fire without checking what’s behind the drywall. What’s behind it is often completely obstructed: generations of construction debris, pigeon nests, and soot collapse from the adjacent flues sharing the same stack. Before any fire gets lit in a reopened East Harlem fireplace, that flue needs a full camera inspection. We’ll tell you plainly if it can wait, and we’ll show you why.

FAQs - Chimney Cleaning & Sweep in East Harlem
Yes, and it’s not a marketing line. Pre-war tenement chimneys are shared stacks. Multiple flues run inside one brick structure, which means a blockage in one flue can push exhaust into another. We treat every East Harlem job as a multi-flue system, not a standalone fireplace. Cleaning one flue without checking the others is how you get carbon monoxide backdrafting into a renovated apartment. The price is higher than a single-family sweep because there are more flues to check and the rooftop access is more involved, but ignoring that reality is how buildings end up in the news.
No, and we’ll tell you why with a camera, not a warning. A fireplace that’s been sealed for decades in an East Harlem tenement usually has a flue full of debris: construction dust, pigeon nesting, and soot that fell in from the shared stack above it. If you light a fire without checking, the smoke has nowhere to go except back into your apartment or a neighbor’s. We’ll open it up, run the camera, and show you exactly what’s in there. Then you decide. Call (516) 301-1549 and we’ll schedule the inspection.
Carefully, with the right tools, and never with a steel brush on a flue we haven’t inspected first. Third-degree creosote is a hard glaze that bonds to the flue wall. In an unlined or clay-tile East Harlem flue, the brick underneath is already compromised from decades of moisture cycling. Running a steel brush through it can knock loose deteriorated mortar and speed up a collapse. We use rotary chain systems and chemical cleaners matched to the flue material, and we camera-check the flue before and after. If the brick is too far gone to brush safely, we’ll show you the footage and talk about a liner.
Most likely the chimney was swept without a camera inspection, which means the sweep removed surface soot but missed the real problem. In East Harlem tenements, the usual culprits are a collapsed clay tile liner, a blocked section of the shared flue from a neighboring unit, or an oversized flue that’s letting boiler exhaust cool and backdraft into the building. A sweep can’t find any of those. A camera can. Getting the board to pay for it is a conversation we can help with, and we’ll put the findings in a written report they can’t ignore.
Yes, and it affects what we find when we get up there. East Harlem’s position near the Harlem River and the East River means century-old masonry takes a beating every winter. Water seeps into tiny cracks, freezes, expands, and breaks the mortar from the inside. By late winter, rooftop chimneys often show fresh spalling and displaced brick that wasn’t there in October. We work through the winter, but if your chimney cap is near the river or the building is over 80 years old, the cold-season inspection is the one that catches real structural damage. Call (516) 301-1549 before burning season, not after.
