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 the front line against freeze-thaw spalling and nor’easter-driven water infiltration into pre-war masonry stacks. Most brownstone and tenement chimneys in New York were built before 1940, and their original caps and crowns are now cracked, missing, or gone entirely. We provide written pricing before any work begins and include a camera-scan record on every visit. Call (551) 213-5548 for a free estimate.
Why New York Homes Are Different
New York’s dominant housing stock is pre-1940 brownstones, tenements, and low-rise multi-family buildings concentrated in Brooklyn, upper Manhattan, and the South Bronx. These original brick stacks typically contain four to six individual flues serving separate apartments, often unlined or fitted with crumbling terra-cotta liners. Decades of oil-heat use left dense petroleum soot inside those flues. Coastal nor’easters subject aging brick to repeated wind-driven rain, ice infiltration, and freeze-thaw cycling that erodes original lime mortar joints. Spalling and water infiltration are seasonal complaints after every hard winter. Cold stretches from November through March mean decorative fireplaces and central-boiler flues see months of continuous use, accelerating creosote and soot buildup. In Brooklyn and upper-Manhattan co-op buildings, the chimney is a shared building system controlled by a board or management company, not an individual owner. A single FDNY inspection deficiency notice or Local Law 11 facade report flagging a deteriorated cap can trigger a building-wide remediation contract affecting fifty units.
Our Main New York Services
New York homeowners and co-op boards call us most about these three services, each with its own dedicated page covering pricing, local conditions, and what the job includes.
Chimney Cleaning & Sweep in New York
A sweep in New York often means removing dense petroleum-soot accumulation from flues that carried #4 and #6 heating oil for decades before Clean Heat conversions. We inspect with a camera down the flue before and after, document everything in writing, and give you a fixed price before the first brush goes up. See Chimney Cleaning & Sweep in New York for what a sweep costs here and what we check.
Chimney Repair in New York
Nor’easter exposure means spalled brick, open mortar joints, and water-damaged crowns show up on New York chimneys every spring. Repair work here is rarely cosmetic: a deteriorated crown or cracked flue liner is a structural and fire-clearance issue, not a surface problem. Read Chimney Repair in New York for repair scopes, costs, and how we document the condition before quoting.
Fireplace Services in New York
Gut-renovated brownstones frequently reopen decorative fireplaces that haven’t been swept in thirty or more years. The flue may be unsafe, the damper seized, and the smoke chamber parged with loose mortar. Our fireplace work starts with a Level 2 camera inspection so you see what we see. Details are on Fireplace Services in New York.

BeforeAfterChimney Cap & Crown in New York
A cracked crown or missing cap on a pre-war New York chimney lets nor’easter rain and freeze-thaw cycles into the stack all winter. Water gets behind the brick face, pops the mortar, and spalls the masonry. A proper Chimney Cap & Crown installation stops that cycle at the top of the flue, before the damage spreads to the liner and smoke chamber.
Cap Installation
Signs you need it
You see an open flue tile with no metal cover, bird activity, or water pooling at the base of the firebox after rain.
What it costs in New York
Cap installation in New York typically runs $375 to $675 for a standard single-flue stainless cap, installed.
How we do it
We measure the flue opening, install the correct Olympia Chimney or Famco cap with mechanical fasteners, and photograph the finished installation.
Cap Replacement
Signs you need it
The existing cap is rusted through, missing mesh, or blown off the flue by a nor’easter.
What it costs in New York
Cap replacement in New York runs $375 to $675 including removal of the old cap and installation of the new one.
How we do it
We remove the old cap, check the flue tile for damage, then mount and secure the replacement cap and document it with photos.
Crown Repair
Signs you need it
The concrete crown has visible cracks, missing sections, or standing water after it rains.
What it costs in New York
Crown repair in New York runs $450 to $900 depending on crack coverage and surface preparation.
How we do it
We remove loose material, build or repair the crown with a proper overhang and drip edge, and seal it against water entry.
Crown Coating
Signs you need it
The crown is intact but porous, or hairline cracks keep reappearing after repointing.
What it costs in New York
Crown coating in New York runs $350 to $750 for a full clean, prep, and elastomeric sealant application.
How we do it
We clean the crown surface, fill hairline cracks, and apply a flexible waterproof coating so the crown sheds water instead of absorbing it.
What Chimney Cap & Crown Costs in New York
| Item | Typical range in New York |
|---|---|
| Cap installation | $375 - $675 |
| Cap replacement | $375 - $675 |
| Crown repair | $450 - $900 |
| Crown coating | $350 - $750 |
Does a cracked crown in New York need immediate repair?
Yes, typically. A cracked crown on a pre-war masonry chimney lets nor’easter rain and freeze-thaw cycles attack the brick below it every winter. The damage compounds each season and spreads to the liner. Call (551) 213-5548 for a written quote.
Can a cap be installed on a multi-flue New York chimney?
Yes. Multi-flue caps cover the entire top of the stack, which is common on brownstone and tenement chimneys in New York with four to six flues. We measure the full crown footprint and custom-fit the cap. Call (551) 213-5548 for exact pricing.
Chimney Liner & Rebuild in New York
New York’s Clean Heat conversions forced thousands of pre-war buildings to switch from oil to natural gas, which changes flue gas temperature and chemistry inside flues that carried heavy petroleum soot for generations. A liner that handled oil exhaust may be unsafe or non-compliant for gas appliances. Our Chimney Liner & Rebuild work starts with a camera inspection so we can show you the existing liner condition before we quote anything.
Stainless Steel Liner
Signs you need it
The flue is unlined, the terra-cotta liner is cracked, or you’re converting from oil to gas under Clean Heat and the existing flue doesn’t meet clearance requirements.
What it costs in New York
Stainless steel liner installation in New York typically runs $3,500 to $7,000 for a standard single-flue run.
How we do it
We size the liner to the appliance BTU load, install it from the top down with insulation as required, and document the entire run with camera footage.
Liner Replacement
Signs you need it
The existing terra-cotta liner is spalling, cracked, or has gaps that show on camera as open joints or flue gas leakage.
What it costs in New York
Liner replacement in New York runs $3,500 to $7,000 depending on flue height and access.
How we do it
We remove or bypass the failed liner, install a properly sized replacement, and give you before-and-after camera scans.
Partial Rebuild
Signs you need it
The top three to five feet of brick above the roofline are loose, spalled, or leaning after years of nor’easter exposure.
What it costs in New York
Partial chimney rebuild in New York typically runs $3,000 to $6,000 for the top section and crown replacement.
How we do it
We rebuild the damaged section with new brick and mortar, install a proper concrete crown, and photograph the finished stack.
Full Chimney Rebuild
Signs you need it
The stack is structurally compromised from the roofline down, with severe spalling, open mortar joints, and visible lean.
What it costs in New York
Full chimney rebuild in New York runs $8,000 to $18,000 depending on height, access, and scaffolding requirements.
How we do it
We take the stack down to a sound base, rebuild with matching brick, reline the flue if needed, and provide a photo record of every stage.
What Chimney Liner & Rebuild Costs in New York
| Item | Typical range in New York |
|---|---|
| Stainless steel liner | $3,500 - $7,000 |
| Liner replacement | $3,500 - $7,000 |
| Partial rebuild | $3,000 - $6,000 |
| Full chimney rebuild | $8,000 - $18,000 |
Does a Clean Heat gas conversion in New York require a new liner?
Often yes. Gas flue gas is cooler and wetter than oil exhaust, so an old unlined or damaged terra-cotta flue may not handle it safely. We camera-scan and tell you plainly if the liner can stay or must go. Call (551) 213-5548 for a written quote.
Is a partial rebuild in New York enough, or do I need a full rebuild?
If damage is limited to the top section above the roofline, a partial rebuild is usually sufficient. If the brick below the roofline is also spalled or the stack is leaning, a full rebuild may be required. We show you the camera evidence either way. Call (551) 213-5548 for an exact assessment.
