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.
Fast, Reliable Chimney Repair Across New York
Chimney repair in New York typically costs between $450 and $4,800 depending on what’s actually wrong, and the work usually gets done within one to two weeks of the written quote. Most jobs we see in New York are repointing on pre-war brick stacks, flashing replacement where the roof meets the chimney, or liner work tied to a Clean Heat gas conversion. Corrine Halstead and the Level Two Chimney New York team know exactly how New York’s attached housing and shared flues change what a repair involves. Call (551) 213-5548 for an exact written quote; estimates are free, and the price we give you is the price on the invoice.
Why Level Two Chimney New York Is New York’s Preferred Chimney Repair Company
We don’t do flashlight inspections. Every service visit in New York includes a camera scan of the flue under NFPA 211 Level 2 standards, and Clause 4 of the Haven Standard requires a documented photo record on every job. We’ve been doing this since 2009, and across more than 38,000 New York chimneys inspected and cleaned, the practice has never changed: written price, written scope, written warranty before anyone touches the brick.
Our crews in New York are background-checked, uniformed, and assigned by name. You get a text when the technician is on the way. Live phone support runs 24/7, so if you call at 11 p.m. because a nor’easter ripped a flashing loose, a person answers.
We also work directly with co-op boards and property managers in upper Manhattan, the South Bronx, and Brooklyn. That’s a different conversation than a homeowner with a smoky fireplace. The chimney is a shared building system, and when Local Law 11 flags it, fifty units need answers at once. We’ve handled that call enough times to know what the board needs: a camera report, a written scope per flue, and a price that holds.
Our Chimney Repair Services in New York

Mortar Repointing
Most New York chimney repair calls start here. Pre-war brownstones and tenements were laid with lime mortar, and after 80 to 120 years of nor’easter-driven rain and freeze-thaw cycling, those joints turn to sand. Repointing on a typical New York four-flue stack runs $1,800 to $4,200 depending on height, access from the roof, and how much joint material has to be raked out. We match the original mortar composition, not just the color, because modern Portland cement on old soft brick causes spalling. In neighborhoods like Washington Heights and Park Slope, we repoint stacks on attached homes where the neighboring chimney is only a few feet away, which matters more than most homeowners realize.

Chimney Rebuilding
When the brick above the roofline is spalled, leaning, or missing pieces, repointing won’t hold it. We rebuild the stack from the roof line up, sometimes from the smoke chamber if damage runs deep. A full chimney rebuild in New York runs $3,500 to $8,000 for a standard two-flue residential stack, more if it’s a shared four-flue co-op chimney with scaffolding requirements and Local Law 11 filing pressure behind it. We rebuild with materials sourced through Haven’s buying network, including FlueTile and Copperfield products, so the price you’re quoted reflects what the materials actually cost, not a markup padded by supply-chain games.

Flashing Repair
Flashing is where the chimney meets the roof, and in New York it fails constantly. Flat and low-slope roofs, common on brownstones and older apartment walk-ups, pool water against the chimney base. Step flashing, counter-flashing, and the cricket all take abuse. We see rusted galvanized flashing that’s been patched with roofing tar too many times. Flashing repair in New York runs $450 to $1,400 for a standard residential job. On attached New York houses, we check the shared chimney stack on both sides of the property line, because one neighbor’s loose flashing can channel water into the other’s flue chase.

Spalling Brick Repair
Spalling is brick face popping off, and New York’s freeze-thaw cycle makes it a seasonal inevitability. Water soaks into the brick, freezes, expands, and the face shears away. Spalling repair costs $325 to $900 per affected section, but the bigger issue is what’s behind the spalled brick. We’ve opened up New York chimneys where a spalled face disguised a void that had been letting carbon monoxide drift into an adjacent unit. That’s the shared-flue reality in attached housing. Every spalling repair in New York starts with a camera inspection to see what the cosmetic damage is hiding.

Before
AfterHow New York’s Shared Flues Change Everything
In a detached house in the suburbs, one flue serves one appliance, and the chimney is a private system. In New York, four to six individual flues often share a single masonry stack serving separate apartments. A cracked terra-cotta liner in your neighbor’s flue doesn’t just affect your neighbor. If gas exhaust from their boiler backdrafts through a shared void and into your fireplace flue, you get carbon monoxide intrusion, stale odors, and soot staining through your unit. We’ve documented this exact pattern on Riverside Drive, in Bed-Stuy, and along the Concourse in the South Bronx.
That’s why we never diagnose one flue in an attached New York building without checking the others. Cross-contamination through shared flues is the most under-diagnosed chimney problem in this city. The camera scan finds it. The photo record proves it. And the repair, whether it’s a liner replacement, a new multi-flue cap, or full repointing of the shared stack, is priced in writing before work starts.
Trusted Brands We Service in New York

We install and service liners, caps, and flashing systems from manufacturers whose materials hold up to New York’s coastal weather and heavy-use heating seasons. For relining work, we use DuraFlex stainless liners and HeatShield resurfacing systems. For caps, we use Famco and Gelco products in sizes that cover multi-flue New York stacks, which is harder than it sounds when one chimney serves four apartment units. Because we stock these parts through Haven’s buying network, our New York customers aren’t waiting weeks on a specialty liner while a co-op board meeting decides the next steps.
Common Chimney Repair Problems We See in New York Homes
- Petroleum soot from retired oil boilers. NYC’s Clean Heat program forced thousands of pre-war buildings off #4 and #6 oil. Those century-old masonry flues are caked with dense petroleum soot that must be professionally cleaned and often relined before a gas appliance can safely vent through them.
- Freeze-thaw spalling after every hard winter. Coastal nor’easters drive rain into aging brick, and sustained below-freezing stretches from November through March freeze that water inside the masonry. The result is spalled faces and crumbling lime mortar joints by spring.
- Cross-contamination between shared flues. In attached New York housing, a cracked liner in one unit’s flue can let gas exhaust seep into an adjacent flue. We find this most often in pre-1940 tenements where the original terra-cotta liners are still in place.
- Reactivated fireplaces with decades-old creosote. Gut-renovated brownstones in Brooklyn and upper Manhattan often have decorative fireplaces that haven’t been used since the 1980s. Unlined flues last swept thirty-plus years ago hold third-degree creosote glaze that brushes can’t remove. Those need a full reline before the first fire.

Call (551) 213-5548.
One New York job that shows how the pricing actually plays out: our crews were called to a six-story co-op on Riverside Drive in upper Manhattan after a Local Law 11 facade inspection flagged the building’s original brick chimney stack. The four-flue masonry stack had severe mortar erosion from decades of nor’easter-driven rain, with one flue serving a gut-renovated brownstone unit’s fireplace that hadn’t been swept in over thirty years. We repointed the entire stack, installed a multi-flue Famco chimney cap, and relined the oil-soaked flue with a DuraFlex stainless liner to bring the shared system into Clean Heat compliance. The co-op got a camera report for every flue, a written price per line item, and a full photo record when the job closed.
Does My NYC Co-op or Condo Board Need to Sign Off on Chimney Repair?
In New York, if you live in a co-op or condo, the chimney is almost always a building system controlled by the board or management company. You may not be able to hire us directly for work on the shared stack, even if the problem originates in your unit’s flue. What usually happens is this: a board member notices a leak, an FDNY inspection flags a deficiency, or Local Law 11’s facade report notes chimney crown deterioration. The board then solicits proposals. We work with boards and property managers across upper Manhattan, the South Bronx, and Brooklyn, and we structure our reports for that audience: camera footage per flue, written scope, written price, written warranty. If you’re a shareholder or unit owner, the fastest path is to bring our camera report to your board and ask them to authorize the repair. We’ll provide that report whether or not we get the job. That’s Clause 1 of the Haven Standard: the written price and written scope come before work starts, always.

FAQs - Chimney Repair in New York

If the repair is inside your unit, like a fireplace damper replacement, you can hire us directly in most New York buildings. If the work touches the shared masonry stack, the flue lining, or the chimney crown above the roofline, the board or management company must authorize it because it’s a building system. We provide a camera report and written scope you can present to your board to move the decision along. Call (551) 213-5548 and we’ll tell you which category your repair falls into before any money changes hands.
NYC’s Clean Heat program required most large buildings to stop burning #4 and #6 heating oil, which means converted buildings now vent natural gas through flues originally built for oil. Petroleum soot from decades of oil heat leaves a dense, acidic coating inside the flue, and it must be professionally cleaned and often relined before gas exhaust can pass safely. We reline those flues with DuraFlex stainless and document the result with a before-and-after camera record. Our crews have handled this conversion work across upper Manhattan, the South Bronx, and Brooklyn.
Probably not safely, and we’d advise against lighting it until a camera inspection confirms the flue’s condition. Most Brooklyn brownstone fireplaces we inspect haven’t been swept in thirty or more years, and the creosote inside is hardened glazed tar that a brush can’t remove. That’s third-degree creosote, and the only proper fix is a full reline. If you’re in a brownstone in Park Slope, Bed-Stuy, or Crown Heights and want to use that fireplace this winter, call (551) 213-5548 first. The camera inspection is included on every visit, and you’ll see what we see.
The freeze-thaw cycle is the answer. Winter rain and snow soak into New York’s old brick, then sustained below-freezing temperatures expand that water inside the masonry. By March, mortar joints that were marginal in November are spalling and cracking, and the flashing at the roof line has been stressed by ice. The leak you notice in spring is the delayed result of winter water intrusion. The repair usually involves repointing, flashing replacement, and sometimes chimney waterproofing. In New York, a standard spring leak repair runs $700 to $2,400 depending on what the camera shows.
Yes. In attached New York housing, multiple flues share a single masonry stack. If your neighbor’s flue has a cracked liner or is backdrafting gas exhaust, that exhaust can migrate through the shared void into your flue and your apartment. We’ve documented carbon monoxide intrusion on Riverside Drive and in the South Bronx that originated in an adjacent unit’s flue. If you smell soot or exhaust odors in your apartment and you don’t have a fireplace, call (551) 213-5548 and ask us to camera-inspect the shared stack. This is exactly the kind of problem our Level 2 inspection was built to find.
