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.

Chimney cap and crown work in Greenpoint runs $350-$1,100 depending on whether we’re replacing the cap, recoating the crown, or doing structural repointing. The neighborhood’s pre-1900 wood-frame rowhouses carry original multi-flue stacks that were converted from coal to gas mid-century, often without proper termination caps or crown sealing. Between East River humidity and Newtown Creek wind exposure, crowns crack faster here than almost anywhere else in Brooklyn. Call (551) 213-5548 and we’ll put a camera down the flue before we quote anything.
Why Greenpoint Homes Are Different
Greenpoint holds an unusually high concentration of pre-1900 wood-frame rowhouses for Brooklyn. These went up fast and cheap for 19th-century shipyard and factory laborers, which means the chimney stacks are original brick, multi-flue, and sized for coal stoves that nobody has burned in a century. When natural gas arrived mid-century, many of those flues were converted without the stainless-steel liner systems now required under NYC DOB rules. We see two or more active flues side by side in a single tenement stack routinely, which complicates both liner inspection and cleaning sequencing on one job.
The peninsula position does the rest. Bracketed by the East River to the west and Newtown Creek to the north, Greenpoint chimneys take salt-laden humidity and cross-directional wind from two sides at once. Water drives into mortar joints and crowns year-round, then freeze-thaw cycles expand those cracks every winter. Spalling, crown cracking, and structural repointing are recurrent companions to even a basic cleaning call here. If you own a wood-frame rowhouse within four blocks of either waterway, assume your crown has movement you cannot see from the ground.
Our Main Greenpoint Services
Most Greenpoint homeowners call us for one of two reasons: a chimney that hasn’t been cleaned since they bought the house, or a fireplace that smokes or won’t draw. Here’s how those jobs go.
Chimney Cleaning & Sweep in Greenpoint
In Greenpoint, cleaning a multi-flue tenement stack means sequencing each flue separately and confirming no crossover into an adjacent unit’s liner. We use rotary brushes for Class II and Class III creosote, then send a camera down to document the condition before calling it clean. Most pre-war stacks here were never properly lined for gas, so the camera often surfaces a liner issue on what started as a routine sweep. Full details, including local pricing by flue count, are on the dedicated page: Chimney Cleaning & Sweep in Greenpoint.
Chimney Repair in Greenpoint
Repair work in Greenpoint usually means repointing mortar joints that the Newtown Creek wind has been sandblasting for decades, or rebuilding crowns that froze and spalled. Because the housing stock is so old, we frequently find the original lime mortar has turned to dust behind the face brick. That changes the scope from cosmetic tuckpointing to structural work. We write the price and scope before a single brick comes out. See what’s involved: Chimney Repair in Greenpoint.
Fireplace Services in Greenpoint
Many Greenpoint wood-frame rowhouses still have their original fireplaces, and most need dampers, throat repairs, or full smoke chamber parging before they draw properly. Gas inserts and wood stoves need correct sizing against the flue dimensions, and in a pre-war tenement those dimensions can be irregular. We’ll test the draft before any repair recommendation. Read the full breakdown here: Fireplace Services in Greenpoint.

BeforeAfterChimney Cap & Crown in Greenpoint
A cap and crown are the roof-level termination points of your chimney, and in Greenpoint they fail faster than the flue below them because they take every weather event directly. The original coal-era crowns on these pre-1900 rowhouses were poured thin with low-grade mortar. After a century of East River salt spray and Newtown Creek wind, most have spalled into a rough, water-holding surface. A cracked crown lets water sit on top of the flue and seep into the mortar joints below, which is why so many Greenpoint chimney jobs start as a cap quote and turn into a repointing once we inspect the stack. We covered every Chimney Cap & Crown detail on our service page: Chimney Cap & Crown.
Cap Installation
Signs you need it
Water in the firebox after rain, or no cap on the flue at all, which lets rain, leaves, and birds into a stack that may serve multiple units.
What it costs in Greenpoint
Cap installation in Greenpoint runs $350-$750 depending on flue size, material (stainless steel or copper), and whether the flue needs a base plate fabricated for an odd-size tile liner.
How we do it
We measure the flue tile opening, cut or order a cap to match, secure it with self-tapping screws or tapcon anchors, and photograph the finished install from the roof.
Crown Repair
Signs you need it
Hairline cracks radiating across the crown, missing chunks along the crown edge, or water staining on the ceiling directly below the chimney chase.
What it costs in Greenpoint
Crown repair in Greenpoint runs $450-$850 for crack filling and resurfacing, and $900-$2,200 when the old crown must be broken out and re-poured at the correct thickness with a drip edge.
How we do it
We remove loose material, apply a flexible crown coat like Gelco, or, for structural failures, set forms and pour a new concrete crown with expansion area around the flue and a proper overhang.
What Chimney Cap & Crown Costs in Greenpoint
| Item | Typical range in Greenpoint |
|---|---|
| Cap installation | $350-$750 |
| Crown repair (resurfacing) | $450-$850 |
| Crown replacement (re-pour) | $900-$2,200 |
Do I need a new crown or can it be coated?
If the crown has a single crack and no flaking, a flexible coat like Gelco usually seals it for several years. If chunks are missing or the mortar crumbles when probed, the crown is past coating. We’ll show you the camera stills before you decide.
How long does a cap and crown job take in Greenpoint?
Most cap installs finish in one visit. A crown replacement takes one full day. You’ll have a written price before we start, and a photo record of the finished work when we leave. Call (551) 213-5548 for exact numbers.
Chimney Liner & Rebuild in Greenpoint
A chimney liner is the stainless-steel or clay sleeve inside the flue that contains heat and combustion gases, and a rebuild is the structural work on the brick stack itself. Greenpoint’s pre-war tenements are uniquely prone to liner problems because gas conversion happened mid-century without resizing the flue for lower-temperature gas exhaust. Where a coal flue ran hot enough to stay dry, a gas flue runs cool and condenses, which eats at old clay tile and the mortar around it. The result is cracked or missing tiles that spill carbon monoxide into wall cavities rather than out the top. Full scope and pricing on this work lives here: Chimney Liner & Rebuild.
Stainless Steel Liner
Signs you need it
Missing or cracked clay tiles visible during a camera scan, or your gas boiler or furnace is vented into an unlined brick flue, which fails NYC DOB compliance.
What it costs in Greenpoint
Stainless steel liner installation in Greenpoint runs $2,200-$4,000 depending on flue height, diameter, and whether the liner must be insulated for a gas appliance.
How we do it
We size the liner to the appliance’s BTU rating, drop the flexible stainless pipe down the flue, terminate it at a properly fitted cap, and document the full run with camera footage before and after.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning stack, or loose brick the technician can move by hand at the crown level.
What it costs in Greenpoint
Partial rebuild in Greenpoint runs $1,800-$4,000 for the top 15-25 courses of brick, including new mortar, flashing, and crown work where the demo exposes more damage.
How we do it
We demo to sound brick, re-lay courses with matching brick and proper mortar, reinforce the crown, and leave you with a photo archive of every layer we took out.
What Chimney Liner & Rebuild Costs in Greenpoint
| Item | Typical range in Greenpoint |
|---|---|
| Stainless steel liner | $2,200-$4,000 |
| Partial rebuild (top courses) | $1,800-$4,000 |
| Full chimney rebuild | $8,000-$18,000 |
How do I know my liner is actually bad?
The camera scan shows it. We do not recommend a liner replacement without footage of cracked or missing tiles that you can see on the report. If the existing liner is sound, we’ll say so and tell you to keep it.
Can I do a liner and crown at the same time?
Yes, and most Greenpoint jobs combine both: the liner terminates at the crown, so replacing both avoids paying for roof access twice. You’ll get one written price for the whole scope. Call (551) 213-5548 to set it up.
Brands We Service in Greenpoint
We install and service liners and caps from DuraFlex, HeatShield, and Olympia Chimney, keeping common sizes in local stock for Greenpoint’s pre-war flue dimensions. That means most liner jobs here do not wait on a special order. For the full list of what we carry, see our brands.
