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.

AfterChimney Cleaning in Greenpoint, NY
Chimney cap and crown work in Greenpoint is less about adding accessories and more about keeping water out of masonry stacks that have stood since the 1890s. The row houses along Manhattan Avenue, Nassau Avenue, and the side streets running toward the East River share a common failure: crowns that were poured decades ago with standard mortar, now spalling and open to rain. A cracked crown in Greenpoint means water enters the top of the stack, runs down through freeze-thaw cycles, and pushes apart clay-tile flues that may already be undersized from a century of fuel changes. Call (516) 301-1549 and we’ll scope the top of your stack with a camera before recommending any cap or crown repair.
Why Greenpoint Homes Are Different
The chimney you see above a Greenpoint roofline is probably original to a building constructed between 1880 and 1920. Most of these two-to-four-story Italianate and Romanesque Revival brick rowhouses were built with multiple flues serving separate apartments, then retrofitted over decades as coal gave way to oil and finally to gas. Many of those flues were never relined for the appliance they now vent. Add the neighborhood’s position between the East River and Newtown Creek, with its persistent salt-laden humidity, and you get accelerated mortar deterioration at crowns and flashing joints that a drier inland block wouldn’t see. On tight rowhouse blocks, many buildings share party-wall chimney stacks with interleaved flues, and we routinely find that a neighbor’s flue sits inches from another owner’s. A routine cleaning or a cap replacement takes on real consequence when someone else’s carbon monoxide risk is that close.
Our Main Greenpoint Services
These are the three jobs Greenpoint homeowners call us about most, each with its own dedicated page.
Chimney Cleaning & Sweep in Greenpoint
Most Greenpoint flues haven’t been swept in years, and the creosote in a coal-converted gas flue is often glassy and adhered rather than powdery. Our sweep removes the buildup that restricts draft and fuels chimney fires, then we run a camera down the full length of the flue to document condition. On multi-flue party-wall stacks, we isolate the flue we’re working on so nothing we dislodge drifts into a neighbor’s liner. See Chimney Cleaning & Sweep in Greenpoint for full pricing and process.
Chimney Repair in Greenpoint
Brick spalling, cracked crowns, failed flashing, and deteriorated mortar joints show up fast in Greenpoint’s salt-air environment. We tuckpoint with lime mortar that matches the existing joints on pre-war brick, rebuild crowns with a proper drip edge and expansion joint, and replace flashings with copper or aluminum bent to the roof’s actual pitch. Chimney Repair in Greenpoint breaks down each repair type with photos and price ranges.
Fireplace Services in Greenpoint
Greenpoint’s original fireplaces are beautiful but almost none are safe to burn without evaluation. Many have shallow fireboxes, missing dampers, or liners compromised by decades of misuse. We inspect the firebox, smoke chamber, damper, and liner, then repair or convert the fireplace for wood or gas depending on what the condition supports. Fireplace Services in Greenpoint covers fireplace repair, conversion, and maintenance.

AfterChimney Cap & Crown in Greenpoint
Almost every Greenpoint rowhouse needs attention at the top of the stack before anything else. The original crowns on these 1880-1920 chimneys were poured from standard mortar, and after a century of salt air off the East River and freeze-thaw cycles, they crack, spall, and open paths for water. A missing or rusted cap compounds it by letting rain fall straight down the flue, which is why our Chimney Cap & Crown inspections start with drone or roof-level photos of the crown before we quote anything.
Cap Installation
Signs you need it
Rain water or bird debris entering the flue, a rusted or missing cap, or a flue that’s open to weather.
What it costs in Greenpoint
Stainless steel cap installation in Greenpoint typically runs $320-$640 depending on flue size and access.
How we do it
We measure the flue tile, match a stainless cap from Olympia Chimney or Famco to the size, and secure it with mechanical fasteners, not adhesive.
Crown Repair
Signs you need it
Cracks across the crown surface, exposed aggregate, standing water, or mortar pieces in the gutter below the chimney.
What it costs in Greenpoint
Crown repair in Greenpoint averages $500-$1,100, with full tear-out and repour on the higher end.
How we do it
We remove the deteriorated crown, form a new one with a 2-inch overhang and drip edge, and pour it with a flexible sealant that moves with the masonry.
What Chimney Cap & Crown Costs in Greenpoint
| Item | Typical range in Greenpoint |
|---|---|
| Stainless steel cap (single flue) | $320-$640 |
| Multi-flue custom cap | $550-$950 |
| Crown repair or repour | $500-$1,100 |
Does a cracked crown really matter in Greenpoint?
Yes, more than most neighborhoods. Salt air, winter freeze-thaw, and century-old mortar combine to open hairline cracks into widening gaps, letting water behind the brick face and into the flue. Repaired early, a crown costs hundreds. Ignored, the same water drives liner replacement and full rebuilds.
Can you install just a cap without touching the crown?
Usually yes, but only if the crown is stable enough to anchor the cap brackets. We’ll tell you plainly if the crown needs work first and we won’t sell a crown job unless our camera or drone photos show the damage. Call (516) 301-1549 and we’ll send you the pictures.
Chimney Liner & Rebuild in Greenpoint
Greenpoint’s original clay-tile flues were sized for coal and oil boilers with high exhaust temperatures, and many are now venting modern gas appliances at lower temperatures that condense acidic moisture inside the liner. That condensation eats old mortar joints from the inside out. Where liners have failed, a stainless steel reline usually solves it; where the brick itself has lost structural integrity, a partial or full Chimney Liner & Rebuild is the honest call.
Stainless Steel Liner
Signs you need it
Condensation dripping from the cleanout, flue gases in the living space, or an old clay liner with missing mortar joints visible on camera.
What it costs in Greenpoint
Stainless steel liner installation in Greenpoint typically runs $2,800-$5,200 depending on height and access.
How we do it
We size the liner with DuraFlex stainless, insulate it where code requires, and connect it to the appliance with a proper termination cap.
Liner Replacement
Signs you need it
Visible cracks or separations in the clay tile on camera, loose tile pieces at the cleanout, or failed draft that can’t be corrected by other means.
What it costs in Greenpoint
Liner replacement in Greenpoint averages $2,800-$5,200, with HeatShield resurfacing as a lower-cost alternative at $2,200-$3,800.
How we do it
We remove the failed clay liner in sections where possible, prep the flue, and install a continuous stainless liner with insulation and a listed top plate.
What Chimney Liner & Rebuild Costs in Greenpoint
| Item | Typical range in Greenpoint |
|---|---|
| Stainless steel liner (DuraFlex) | $2,800-$5,200 |
| HeatShield resurfacing | $2,200-$3,800 |
| Full chimney rebuild | $3,500-$9,800 |
Do I really need a new liner, or can the old clay tile stay?
If the clay tile is intact and sized correctly for the current appliance, it can stay. In Greenpoint, we often find original coal-era tiles that were never right for gas. Our camera scan shows the actual condition, and we only recommend replacement when the footage shows cracks, gaps, or missing joints.
How long does a liner replacement take in Greenpoint?
Most Greenpoint liner replacements finish in one day. Full rebuilds usually take two to four days depending on roof access and how much brick we’re cutting out. Every job gets a written scope and warranty before we start.
Brands We Service in Greenpoint
We stock and install our brands including DuraFlex stainless liners and Olympia Chimney caps. These are procured through our buying network to keep customer prices honest, and we carry common sizes locally so most cap replacements happen in one visit.

FAQs About Chimney Cleaning in Greenpoint
Most Greenpoint jobs are scheduled within three to five business days. If you have an active carbon monoxide alarm or visible water leaking around the chimney, tell the live person who answers and we’ll prioritize same-day inspection where the schedule allows. Call (516) 301-1549 with the address and we’ll give you an exact window.
Most cleaning, cap installation, and crown repair on existing chimneys doesn’t require a permit in New York City. A full rebuild or any structural alteration to the chimney mass may trigger permit review. We’ll tell you during the quote whether your job falls into that category and who handles the filing.
We work on party-wall stacks regularly in Greenpoint and isolate the flue we’re servicing so dust and debris don’t migrate into your neighbor’s liner. If the repair touches both sides of the stack, we’ll document what we found with photos and give you a written description to share with the neighboring owner. Maintenance responsibility on shared stacks isn’t always clear in the deed, but the condition report gives you a place to start.
