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 New York, NY
Chimney work in New York means pre-war brick, party walls, and flues that once burned coal or heavy heating oil. Most calls we run start as a cap or crown issue: water getting in through a cracked crown, or a missing cap letting rain, pigeons, and sparks do damage. If you own a rowhouse in Brooklyn or a co-op unit in Harlem, the chimney above you probably serves multiple flues, and the fix usually costs less than the water damage it prevents. Call (516) 240-9612 for a written quote before any work starts.
Why New York Homes Are Different
New York’s chimney stock is mostly 1880s to 1940s attached brick rowhouses and pre-war apartment buildings. Those stacks were built for coal-fired boilers and kitchen ranges, then converted to oil or gas, often leaving flues unlined or fitted with clay tile that has cracked over decades of thermal cycling. In attached blocks across Park Slope, Bed-Stuy, and Harlem, a single masonry stack typically carries four to six flues serving separate units, which means one neighbor’s problem becomes your problem. Coastal humidity in Red Hook and the Rockaways accelerates spalling on exposed brick crowns, and cold, damp winters from November through March push sustained boiler use that loads flues with soot faster than a fireplace-only home. Co-op and condo buildings add a layer most cities don’t have: board approval, DOB permits, and coordination with the super before a tech can even set up a ladder.
Our Main New York Services
New York homeowners call us most often for two things: getting a dirty or blocked flue cleaned and getting a damaged chimney repaired before water or fire does real damage. Here’s how each works in the city.
Chimney Cleaning & Sweep in New York
Cleaning in New York often means removing deposits that aren’t typical wood creosote. Thousands of buildings burned No. 4 and No. 6 heating oil for decades before NYC Local Law 43 phase-outs, leaving tar-like residual oil inside boiler flues that standard brushes won’t touch. We use different chemistry and tools for that, and we camera-scan every flue before and after so you see what was removed. Chimney Cleaning & Sweep in New York is booked with a written price and a photo record on completion.
Chimney Repair in New York
Repair work in New York frequently involves party-wall stacks shared between two buildings. A liner collapse in one unit physically affects the neighbor’s flue, and masonry repair may require written consent from the adjoining owner before DOB issues a permit. We document the condition with camera footage, quote the scope in writing, and handle the paperwork questions directly. Chimney Repair in New York includes a documented record when the work is done.
Fireplace Services in New York
Fireplaces in pre-war New York homes were often built for coal, not wood, and the smoke chamber and damper may not be sized right for how you actually use it. We inspect fireboxes, dampers, and smoke chambers with a camera, then give you a written scope before any work starts. Fireplace Services in New York covers everything from smoke issues to full firebox rebuilds.

AfterChimney Cap & Crown in New York
A crown is the concrete or mortar slab that seals the top of the chimney stack; a cap is the metal cover that keeps rain, birds, and debris out of the flue. In New York, crowns on pre-war brick stacks crack from freeze-thaw cycles every winter, and once water gets in, it spalls brick faces and rusts dampers fast. A missing or undersized cap on a multi-flue rowhouse stack is a direct path for water into four or five flues at once. More on the full scope lives on our Chimney Cap & Crown page; below is what we actually see and charge around the five boroughs.
Cap Installation
Signs you need it
Rainwater or bird nesting material inside the flue, or a visible open flue top from the roof or fire escape.
What it costs in New York
Standard single-flue cap installation in New York typically runs $350-$700 depending on roof access and flue size.
How we do it
We measure the flue tile, select a stainless cap sized to the opening, secure it with the right fasteners, and photograph the finished installation.
Crown Repair
Signs you need it
Visible cracks, crumbling mortar at the chimney top, or water staining on the ceiling near the chimney chase.
What it costs in New York
Crown repair in New York typically runs $450-$1,200 depending on the crown’s size and how much old material needs removal.
How we do it
We remove loose or spalled material, build a proper crown with a drip edge and expansion gap, seal it, and photograph the result.
What Chimney Cap & Crown Costs in New York
| Item | Typical range in New York |
|---|---|
| Cap installation | $350-$700 |
| Crown repair | $450-$1,200 |
| Multi-flue cap | $500-$1,800 |
How long does a cap or crown job take in New York?
Most cap installations and standard crown repairs finish in a single visit, usually 1 to 3 hours on site. Roof access in attached rowhouse blocks can add time if we need to coordinate with a neighbor for access. Call (516) 240-9612 for a written time estimate.
Does a cracked crown really need fixing now?
Yes, because every freeze-thaw cycle widens the crack, and the water it lets in spalls brick and rusts dampers. The repair is cheaper before the damage reaches the flue liner. We’ll show you camera photos of exactly what’s happening before you commit.
Chimney Liner & Rebuild in New York
A flue liner is the protective passage inside the chimney that carries exhaust up and out; in New York, older stacks often have cracked clay tile liners or no liner at all. That’s a carbon monoxide risk and a fire hazard, especially in attached rowhouses where a liner failure in one unit affects the neighbor’s flue too. When the damage is bad enough, we rebuild part or all of the stack. Details on materials and methods are on our Chimney Liner & Rebuild page.
Stainless Steel Liner
Signs you need it
Flue gases backing up into the home, a cracked clay liner visible on camera, or a boiler conversion that changed flue sizing.
What it costs in New York
A stainless steel liner in New York typically runs $1,100-$2,200 installed, depending on flue height and diameter.
How we do it
We camera-scan the existing flue, size the liner to the appliance, drop and insulate the liner, connect it top and bottom, and photograph the full run.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning stack, or mortar joints eroded to the point where bricks move by hand.
What it costs in New York
A partial rebuild in New York typically runs $1,800-$4,500 depending on how many courses of brick need replacement.
How we do it
We tear down to sound brick, rebuild with matching brick and proper mortar, install a new crown, and document every course with photos.
What Chimney Liner & Rebuild Costs in New York
| Item | Typical range in New York |
|---|---|
| Stainless steel liner | $1,100-$2,200 |
| Partial rebuild | $1,800-$4,500 |
| Full chimney rebuild | $4,000-$12,000 |
Does my New York rowhouse need a liner if I only have a gas boiler?
Usually yes. Gas exhaust is cooler and wetter than coal or oil exhaust, and it condenses inside unlined masonry flues, which deteriorates mortar fast. We’ll camera-scan and show you the condition before recommending any liner work. Call (516) 240-9612 for a written quote.
Can you really rebuild a chimney on a party wall in New York?
Yes, and we do it regularly. If the stack is shared, your neighbor’s written consent may be needed before DOB issues a permit. We’ll walk you through exactly what’s required for your specific building before any work begins.
