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 Greenpoint
Chimney repair in Greenpoint usually starts with the flue, not the brick. On most blocks here, the original unlined clay flue from 1910 is still venting a modern gas boiler, which is why our Greenpoint repair calls begin with a camera scan, not a guess. A typical flue liner installation runs $2,800-$4,600 in Greenpoint, and mortar repointing on an exposed crown runs $900-$2,200 depending on access and condition. We serve every block from McGolrick Park to the Newtown Creek waterfront, and we answer calls at (551) 213-4778 seven days a week.
Why Level Two Chimney Financial District Is Greenpoint’s Preferred Chimney Repair Company
We’ve worked on more than 38,000 chimneys since 2009, and a disproportionate share of the complicated ones sit in Greenpoint. The neighborhood’s attached two-family homes and pre-WWI brick rowhouses create flue problems that don’t exist in newer construction. Shared stacks, abandoned flue tiles, coal-era masonry repurposed for high-efficiency gas exhaust: these are the jobs that send other companies back to the truck. We walk the block and already know what we’re likely to find before we open the roof hatch.
Every Greenpoint job gets a background-checked, uniformed technician with a license number on the page and a text when they’re on the way. What we find, we show you: camera footage down the flue, photos of the crown and flashing, and a written scope of work priced before anything starts. That’s Clause 1 of the Haven Standard. The photo record on completion is Clause 4. Greenpoint homeowners who’ve hired us tell us the same thing: there were no surprises at the end, because there were no surprises at the quote.
Our dispatch comes from our New York City office, and crews arrive in Greenpoint with parts for the neighborhood’s typical repair sequence already loaded. That means less waiting when you need a DuraFlex liner or a Gelco crown coat mid-job. We know the difference between a Nassau Avenue three-family tenement stack and a Driggs Avenue two-unit rowhouse flue, and the repair approach is not the same for either.
Our Chimney Repair Services in Greenpoint
Here’s what we actually do most often in Greenpoint, based on the housing stock. These four services cover the majority of what Greenpoint chimneys need, and each one starts with a documented camera inspection rather than a visual guess.
Mortar Repointing
Greenpoint’s brick stacks face moisture from two directions: the East River to the west and Newtown Creek to the north. That persistent damp air works into the mortar joints and, combined with winter freeze-thaw cycles, loosens them faster than in drier inland neighborhoods. A repointing job on a Greenpoint crown or shoulder typically runs $1,200-$2,800, and it’s the single most common repair we perform on the neighborhood’s exposed chimneys.
Spalling Brick Repair
Spalling is what happens when water gets into brick faces and freezes, popping the outer shell off the brick. On Greenpoint’s river-adjacent blocks, spalling appears most often on the upper courses of the chimney where wind-driven moisture hits hardest. We cut out the damaged units, replace them with matching brick where salvaged stock is available, and repoint the surrounding joints. Expect $500-$1,500 per affected area depending on how many faces are involved and how much brick needs to be sourced.
Chimney Waterproofing
We apply a vapor-permeable siloxane waterproofing to the masonry, which keeps out liquid water while letting the chimney breathe. Given Greenpoint’s salt air from the East River and Newtown Creek, we recommend this after any repointing or spalling repair. A full waterproofing treatment on a Greenpoint chimney runs $800-$1,600, and it delays the next repointing cycle by years. Corrine Halstead, who runs our operations, has been pushing waterproofing as a standard part of Greenpoint repairs because the failure repeat rate without it is too high.
Flashing Repair
Flashing is the metal where the chimney meets the roof, and on Greenpoint’s flat and low-slope roofs it takes a beating. The expansion and contraction from coastal temperature swings pulls flashing loose over time. A leak around the chimney is usually flashing, not masonry. We replace or reseal flashing with a written quote in hand, and most Greenpoint flashing repairs run $700-$1,500 depending on the roof type and whether the old flashing needs to be fully stripped.

BeforeAfterTrusted Brands We Service in Greenpoint
We stock DuraFlex stainless liners and Gelco crown treatments specifically because they fit the repair profile of Greenpoint’s older masonry chimneys. HeatShield resurfacing is another option we use when a flue is cracked but the original clay tile is still structurally sound. The materials we install are sourced through the Haven buying network, which keeps customer pricing honest and means we’re not waiting on a distributor to ship a liner from out of state when a Greenpoint boiler needs to vent today.
Common Chimney Repair Problems We See in Greenpoint Homes
- Shared flue backdraft in attached two-family homes. When a lower unit’s boiler kicks on, it can push exhaust into the upper unit’s living space instead of up the stack. We find this on Mercer Street and Norman Avenue and every other attached block in the neighborhood. The fix is isolating the flue with a dedicated liner.
- Freeze-thaw spalling on crowns facing Newtown Creek. The creek side of Greenpoint wears faster. Salt air and persistent moisture from the water accelerate masonry surface loss. Crowns on the north-facing side of a house need repointing or rebuild roughly twice as often as interior-adjacent chimneys.
- Third-degree creosote glaze inside a flue that was never relined for gas. Even a fireplace that “looks clean” from the firebox can have a hardened, shiny creosote layer baked onto the flue walls. This is a fire hazard, and we find it regularly in Greenpoint rowhouses that switched from wood to gas without the liner being replaced.
- Undersized flues venting modern condensing boilers. The original coal flue in a 1910 Greenpoint rowhouse was not sized for a 2026 high-efficiency boiler. The result is condensation, corrosion, and carbon monoxide risk. Relining is not optional in these cases; it’s the repair.

These ranges reflect what we’ve quoted on Greenpoint jobs in the past 12 months. Roof access is a factor: a tight fifth-floor walk-up with a steep ladder pitch costs more than a two-story flat roof. The condition of the flue matters most. We give a written price before any work starts, and you can bring us a competitor’s written estimate for a free second opinion on anything we’ve scoped.

FAQs - Chimney Repair in Greenpoint
No. Current NYC Building Code requires gas appliances to vent through a listed liner, and an original unlined brick flue from the pre-WWI era does not meet that standard. In Greenpoint specifically, this is the neighborhood default rather than a rare exception: the coal-to-oil-to-gas conversion history left most blocks with unlined or undersized flues now venting modern boilers. The fix is a stainless liner installed to code, followed by a camera verification to document the installation. Call (551) 213-4778 to get a written quote for your specific flue setup.
You’ll notice drafts, backpuffing, or a musty smell in your unit when your neighbor’s boiler runs, even if your own appliance is off. In Greenpoint’s attached two-family homes, shared or adjacent flue stacks make cross-ventilation common. The reliable way to confirm is a draft test and CO reading at the firebox. If we find cross-venting, the standard fix is isolating your flue with a dedicated liner and sealing the adjacent abandoned tile. Call (551) 213-4778 for a camera inspection that documents exactly what’s happening.
Because Greenpoint sits between the East River and Newtown Creek, and that means salt air and persistent moisture hit your crown from both sides. The water works into the mortar, freezes, and breaks the joints. A crown on the north side of a Greenpoint house, facing Newtown Creek, wears noticeably faster than one mid-block. Repointing with a mortar matched to your original brick, followed by a siloxane waterproofing, stretches the interval significantly. Call (551) 213-4778 for a free estimate and we’ll tell you whether your crown needs work this year or can wait.
The crack widens with every heating cycle, and if the flue is original Greenpoint clay tile from the pre-WWI era, it’s already near the end of its service life. A small crack becomes a gap, exhaust finds the masonry rather than the outside, and carbon monoxide can enter the living space. We’ve seen units on Norman Avenue where a “small crack” revealed a collapsed flue tile less than two seasons later. Don’t wait on this one. Call (551) 213-4778 and we’ll camera-scan the flue and give you a written recommendation with photos.
If your Greenpoint chimney also vents a gas boiler or water heater, yes, because the flue is working year-round even when the fireplace isn’t used. Creosote from the fireplace plus condensation from the gas appliance creates a compound problem. Given Greenpoint’s unlined flue history and shared stacks, we recommend the NFPA 211 Level 2 inspection annually, which includes the camera scan and photo record we’ve been doing on every job since 2009. Call (551) 213-4778 to book an inspection; we’ll give you the written report on-site.
