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 cap and crown work in New York is a different job than it is almost anywhere else. The city’s 1880-1940 rowhouses and brownstones carry shared chimney stacks with four to six flues per stack, and the freeze-thaw cycle that cracks exposed masonry here runs from November through March. Crown failures on a Brooklyn brownstone don’t just leak water into one fireplace; they can send moisture down multiple flues and into party walls. Call (551) 213-4778 for a camera-scan inspection and a written price before any work starts.
Why New York Homes Are Different
New York’s chimney stock is defined by its pre-war multi-family housing. In Harlem, Crown Heights, and the South Bronx, a single masonry chimney stack often serves four to six separate flues across multiple apartments, mixing fireplaces, gas boilers, and abandoned coal or oil flues from fuel conversions decades ago. The original brick flues were almost never lined, and the clay tile liners added during oil-to-gas conversions were frequently undersized for the appliances they now vent.
The climate compounds the problem. New York crosses 32°F dozens of times each winter, and each crossing is another expansion-contraction cycle that pulls at mortar joints and crown edges. Coastal salt air in Red Hook and the Rockaways accelerates spalling on exposed brick. The result is that crown repair and cap installation here are rarely about one chimney; they are about a shared stack that might serve three or four units, with a Department of Buildings inspection sign-off hanging over the landlord’s head.
Our Main New York Services
Most New York homeowners call us for one of three reasons: a chimney that hasn’t been cleaned in years, a leak or masonry failure, or a fireplace that doesn’t draw or heat properly.
Chimney Cleaning & Sweep in New York
Cleaning a New York chimney usually means working through accumulated oily soot from decades of oil and gas combustion, not just wood creosote. We run an NFPA 211 Level 2 camera scan on every cleaning, which matters here because abandoned side flues within active chases are common and can hide breaches. See the full scope on the Chimney Cleaning & Sweep in New York page.
Chimney Repair in New York
Repair jobs in New York typically involve crown rebuilding, flashing replacement, and mortar repointing on stacks that have endured a century of freeze-thaw stress. In multi-unit buildings, we document everything photographically because the DOB sign-off process may require it. Learn more on the Chimney Repair in New York page.
Fireplace Services in New York
Gas and wood fireplace service in New York ranges from damper adjustment to full smoke chamber parging. In rowhouse conversions, we regularly find that the original fireplace flue was never lined when the building switched fuels. Details are on the Fireplace Services in New York page.

BeforeAfterChimney Cap & Crown in New York
Cap and crown failure is the most common call we get from New York rowhouse owners, and it’s usually visible from the street before it’s visible inside the home. A cracked crown on a brownstone’s shared stack lets water into four or six flues at once; in freeze-thaw conditions, that water becomes a wedge that pries the crown apart from the inside. Our Chimney Cap & Crown service starts with a camera scan to document what’s actually failing, then a written scope and price before anything gets touched.
Cap Installation
Signs you need it
You see rust stains streaking down the chimney face, or water pooling in the firebox after rain.
What it costs in New York
Standard single-flue cap installation in New York runs $285-$475; multi-flue caps for shared rowhouse stacks run $650-$1,200.
How we do it
We measure the flue, verify the crown can accept mechanical fasteners, install the cap with a screened spark arrestor, and photograph the finished work.
Crown Repair
Signs you need it
You see hairline cracks spider-webbing across the crown surface, or spalled chunks of mortar on the roof or in the gutter.
What it costs in New York
Crown repair in New York ranges $450-$900 for resurfacing; a full tear-off and pour runs $1,100-$2,500 depending on access and stack height.
How we do it
We grind out deteriorated material, build a proper drip edge, apply a flexible waterproof membrane, and document before and after.
What Chimney Cap & Crown Costs in New York
| Item | Typical range in New York |
|---|---|
| Cap installation (single flue) | $285-$475 |
| Multi-flue cap (brownstone stack) | $650-$1,200 |
| Crown repair / resurfacing | $450-$900 |
How long does a crown repair last in New York?
A properly installed crown with a drip edge typically lasts 15-20 years in New York, though rowhouse stacks facing the prevailing wind may need touch-ups sooner. The sealant and membrane we use tolerate freeze-thaw stress well. Call (551) 213-4778 to schedule a camera scan first.
Do brownstone shared stacks need a different cap approach?
Yes. Shared stacks with multiple flues need a custom-fabricated multi-flue cap rather than four individual caps. We measure all flue openings and fabricate to the stack footprint for a watertight seal across the whole crown. Call (551) 213-4778 for a written quote.
Chimney Liner & Rebuild in New York
Liner work in New York is a carbon monoxide issue before it’s a fireplace issue. Gas boilers and water heaters venting into unlined or crumbling clay flues push CO back into living spaces, and in shared rowhouse chases, a damaged liner can become a migration pathway between units. Our Chimney Liner & Rebuild work starts with a camera scan and a written report you can actually read, then the right liner for the appliance, not just the flue.
Stainless Steel Liner
Signs you need it
Your camera scan shows missing or cracked clay tile, or the gas boiler vents into an unlined brick flue.
What it costs in New York
Stainless steel liner installation in New York runs $2,500-$5,500 for the liner itself; total job cost including insulation and connection work runs $4,500-$9,000.
How we do it
We size the liner to the appliance’s BTU output, insulate it, pull it down the flue, and connect with a sealed top plate and tee.
Partial Rebuild
Signs you need it
Brick is crumbling or missing from the top five to ten courses of the stack, or the flue tile is visibly broken at the crown line.
What it costs in New York
Partial chimney rebuilds in New York start around $2,000 and run to $6,000 depending on stack height, course count, and roof access.
How we do it
We demolish to stable masonry, re-lay brick with matching mortar, install a new flue liner section, and cast a new crown, documenting each stage.
What Chimney Liner & Rebuild Costs in New York
| Item | Typical range in New York |
|---|---|
| Stainless steel liner (installed) | $4,500-$9,000 |
| Flexible liner (gas appliance) | $2,300-$4,600 |
| Partial rebuild (top courses) | $2,000-$6,000 |
Does my New York rowhouse need a liner if I only use the fireplace occasionally?
If the flue is unlined or the clay tile is cracked, yes, even occasional use is risky. The cost of a liner is far less than repairing smoke damage or addressing CO exposure. Call (551) 213-4778 for a camera-scan evaluation first.
Can a liner be installed in a shared brownstone stack without disturbing neighbors?
In most cases, yes. Liner installation is done from the roof down, so no access to neighboring units is required. We coordinate scaffolding and roof access with the building, not the individual apartments. Call (551) 213-4778 for details on your building type.

What pushes prices up in New York is access: five-story rowhouses need more scaffolding, shared stacks mean coordinating with neighbors or the building, and DOB sign-off requirements can add inspection time. What never changes is the written price before work starts, a documented photo record when it’s done, and the 365-Day Done Right Promise on every job under the Haven Standard.

It depends on the scope. Cleaning and minor crown repair typically don’t require a permit, but liner replacement and rebuilds on multiple-dwelling buildings may trigger DOB inspection requirements. We’ll tell you exactly what applies to your building in writing before work starts. Call (551) 213-4778 with your address.
Yes, that’s most of our New York work. We handle multi-flue stacks where several apartments share one masonry chase. Our camera scan documents each flue separately, and we seal off unused flues to prevent CO migration between units in the same building.
