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 Repair Across New York
Chimney repair in New York typically runs $450-$1,400 for repointing and flashing work, $900-$3,200 for partial rebuilding, and $1,800-$5,500 when a liner resurfacing or replacement is involved. Most repairs on pre-war brownstones and tenements take one to two days once we’re on the roof, depending on how many flues are in the stack. If you’re seeing spalling brick, a leaking hearth, or moisture staining around your chimney breast in a New York row house, call (862) 319-8047 and we’ll put a camera down the flue before quoting anything.
Why Level Two Chimney Manhattan Is New York’s Preferred Chimney Repair Company
New York’s chimneys are not like the ones in the surrounding suburbs. A single brownstone stack in Park Slope or Bed-Stuy often carries two or three flues side by side: one venting a gas boiler, one dormant from a fireplace that hasn’t been used since the oil burner was pulled, and sometimes a third serving a kitchen exhaust. Getting the wrong flue cleaned or repaired is a real hazard here, because the live boiler vent is the one that kills people when it’s blocked. We scope every flue with a camera and label what we find before any work is proposed.
Corrine Halstead leads our repair crews, and she’s spent years working New York’s pre-war stock. Our repair customers in New York frequently tell us they called us because a previous company quoted a full liner rebuild after a flashlight inspection and no photos. That’s not how we work. Our camera-scan documentation is included on every visit, and it’s been standard practice since 2009, years before it became Clause 4 of the Haven Standard. If we can’t show you the damage on screen, we won’t ask you to pay to fix it.
We answer the phone around the clock. When you call (862) 319-8047, a live person picks up, not a voicemail tree. Our techs are background-checked, uniformed, and arrive with their license number printed on the job paperwork. You’ll get a text when your technician is on the way to your building in New York, and a written price, written scope, and written warranty before anyone picks up a trowel.
Our Chimney Repair Services in New York
Mortar Repointing
New York’s freeze-thaw winters tear at mortar joints, especially on the exposed rooftop sections of masonry chimneys. In neighborhoods like Astoria and Long Island City where the harbor humidity works its way into brick faces, repointing is the most common repair we perform. We grind out deteriorated mortar to a proper depth and repack with a mix matched to the existing brick’s hardness so the chimney moves as one unit through the next winter cycle. Typical repointing on a New York chimney runs $450-$1,200 depending on height and how many faces need work.
Spalling Brick Repair
Spalling is the flaking, popping, or shattering of brick faces. It happens when water gets into the brick, freezes, and expands. New York’s exposed rooftop chimney sections are particularly vulnerable, and waterfront areas in lower Manhattan, Brooklyn, and Queens see higher spalling rates because of salt-heavy air and constant moisture. We remove damaged brick units and replace them with new brick matched to your building’s color and profile, then address the moisture source so the same bricks don’t fail in 18 months. Spalling brick repair in New York generally falls between $600 and $1,800, with partial sections at the lower end and full-face replacement higher.
Chimney Waterproofing
Waterproofing in New York is not optional on pre-war brick. The brick itself is often 80 to 140 years old and far more porous than modern masonry. We apply a vapor-permeable siloxane waterproofing compound that lets the brick breathe while blocking bulk water. This matters in New York’s damp coastal climate where sealing a chimney with the wrong product traps moisture inside and accelerates spalling from behind. Chimney waterproofing runs $400-$900 for an average New York chimney stack, and we always verify the crown and flashing are shedding water correctly before treating the masonry itself.
Flashing Repair
Flashing is the metal boundary where the chimney meets the roof, and it fails silently. On New York’s flat and low-slope roof decks, a poorly cut or corroded flashing lets water run down the chimney chase into ceiling cavities and along the interior brickwork. We see this constantly in brownstones where the original flashing was installed with materials never intended for 100 years of New York weather. Flashing repair in New York typically costs $350-$900, and we can often fix the flashing without touching the rest of the stack, provided the brick and mortar below are sound. See our full Chimney Repair scope for detail on how we assess each job.

When a Park Slope owner needs a flue liner resurfaced, we’re not waiting on a supplier from the Midwest. Corrine and our crews keep the roof sections of New York chimneys stocked with the right parts for the city’s building types, and we pass the procurement savings into the written quote you’ll get before any work begins.
Common Chimney Repair Problems We See in New York Homes
- Missing or cracked clay tile liners. This is the default condition in New York row houses built between 1880 and 1940. Many were originally unlined, or the clay tiles cracked decades ago when the building switched from coal to oil to gas. Without a camera scope, you won’t know until something fails.
- Coal tar and oil residue layered inside gas-converted flues. When a New York boiler was converted from oil to gas, the old combustion deposits stayed behind. Over time, they can condense and run down the flue, causing a burning tar smell and blocking the gas exhaust path.
- Wrong-flue cleaning that leaves the live boiler vent untouched. In Brooklyn and Queens brownstones, a single stack often has two or three flues with no exterior labeling. A chimney repair company that doesn’t scope each flue can clean the dormant fireplace flue and leave the gas boiler exhaust path clogged. We label and document every flue on every visit.
- Repointing done without fixing the moisture source. If the chimney crown is cracked or the flashing is failing, rainwater keeps saturating the brick behind the repointed joints. One New York freeze-thaw winter later, the spalling returns. We won’t repoint without checking what’s feeding the moisture, because otherwise you’re paying twice.

FAQs - Chimney Repair in New York
The only way to know is to scope the flue with a camera. Most Brooklyn brownstones built before about 1920 were originally unlined or had clay tile liners that have since cracked. We run a camera down each flue, show you the footage on the spot, and document what’s there. If you have a gas boiler venting into an unlined flue, that’s a real hazard, because combustion gases can leak through the brick and into the building. We’ll show you the footage, explain what it means, and quote the repair only if the camera shows it’s needed. Call (862) 319-8047 to schedule a scope in Brooklyn or anywhere in New York.
Yes, in many cases. The NYC Department of Buildings requires documented chimney inspections for many multi-family building classifications, and that documentation includes photos or camera footage in many compliance files. If you’re selling a brownstone or tenement in New York, don’t rely on a visual check from the sidewalk. We provide camera-scope documentation that meets DOB compliance requirements, plus a written record of everything found and repaired. Call (862) 319-8047 and we’ll walk you through what your building class requires.
Spalling on New York chimney crowns comes from water. Rain and snow soak into the brick, the water freezes overnight, and the expanding ice pops the brick face off. In coastal neighborhoods like Red Hook or the Lower East Side, harbor humidity adds salt to the mix, which accelerates the freeze-thaw damage. We repair spalling by removing the damaged brick, replacing it with matched material, and then fixing the crown and flashing so water stops entering the masonry in the first place. Without that last step, the repair won’t last a single New York winter.
Because the old oil residue and coal tar are still inside the flue. When the boiler runs on gas, it doesn’t burn hot enough to clear out the legacy deposits, so they condense and drip back down the flue, creating that tar smell. This is a classic New York problem, since millions of the city’s buildings were converted from oil to gas decades ago without ever having the flues properly cleaned and resurfaced. We remove the residue and, if the liner is damaged, resurface it with HeatShield so the gas exhaust has a clean, continuous path. Call (862) 319-8047 to get a camera scope of what’s sitting inside your flue.
Yes, in most cases. Flashing failure is isolated to the metal seam where the chimney meets the roof, and it doesn’t automatically mean the brick above is failing. We inspect the flashing, check the surrounding brick and mortar for moisture damage, and if the stack itself is sound, we replace the flashing only. This keeps the repair in the $350-$900 range instead of the $2,000+ a rebuild costs. If we recommend more, we’ll show you the camera footage and photos that justify it, in writing. Call (862) 319-8047 for a written quote.
If your chimney is leaking, spalling, or venting a converted gas boiler, call (862) 319-8047.
