New York City’s pre-war brownstones, mid-century brick row houses, and converted tenements each carry their own chimney history. We’ve rebuilt flues in Park Slope homes where the original terra cotta had crumbled to dust after ninety winters, and we’ve relined chimneys in Financial District high-rises where improper venting set off CO detectors. Frank Calucci started this company on the belief that a chimney job done right should outlast the mortgage. Forty-two years later, that hasn’t changed. Our technicians are background-checked, uniformed, and trained to complete most Best Chimney Liner & Rebuild in New York City, NY jobs in a single visit, with no-hassle upfront pricing so the number on the estimate is the number on the invoice.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue installed inside your existing chimney structure, creating a sealed path for smoke and combustion gases. In New York City, we recommend these for oil and gas systems especially, where corrosive condensation accelerates deterioration of unlined or clay-lined flues. Hearthstone Chimney Co. uses DuraFlex and Olympia Chimney stainless products, sized precisely to your appliance’s BTU output and installed with proper top-sealing termination caps.
Flexible Liner
Flexible liners navigate offset flues and chimney bends that rigid pipe cannot follow, common in older New York City homes where settling has shifted the flue path. We specify flexible liners from DuraFlex when the chimney has offsets exceeding 15 degrees or when access constraints make rigid installation impractical. Our crews carry the full range of diameters on their trucks, which is how we complete most flexible liner installations in one day.
Liner Replacement
Liner replacement becomes necessary when the existing flue shows cracks, gaps, or deterioration visible during Level-2 inspection - conditions that allow heat transfer to combustible framing or leakage of carbon monoxide into living spaces. In neighborhoods like Brooklyn Heights and Gramercy Park, we’ve replaced liners in homes where the original installation failed after just ten years because the wrong material was specified for the fuel type. We document the before condition with photos, remove the compromised liner, and install a replacement engineered for your specific heating appliance and fuel.
Partial Rebuild
Partial rebuild addresses localized failure: the top few courses of brick, a spalled crown, or a deteriorated smoke chamber, while the majority of the chimney structure remains sound. This is the most common rebuild scenario in New York City, where freeze-thaw cycling destroys crowns and shoulders while the stack below stays solid. We match existing mortar color and brick texture where possible, and we always install proper crown flashing and wash to prevent recurrence.
Full Chimney Rebuild
Full rebuild is required when structural integrity is compromised throughout - leaning stacks, widespread brick spalling, or separated wythes that create hazardous conditions. We’ve completed full rebuilds in Williamsburg and Greenpoint after Sandy-related water infiltration, and in Hell’s Kitchen where century-old chimneys had simply exhausted their service life. Hearthstone Chimney Co. handles permitting with the New York City Department of Buildings, constructs to current code, and issues the certificate of completion required for your records, whether it’s an Affordable Chimney Liner & Rebuild in New York City, NY or a full structural project.
Liner Repair
Liner repair with HeatShield cerfractory flue sealant restores minor cracks and gaps in otherwise sound clay flue tiles, avoiding full replacement when conditions permit. This is appropriate for hairline cracks and mortar joint erosion without tile displacement or significant spalling. We perform a video scan after every HeatShield application to verify complete coverage, and we show you the footage - photos you can see, a plain-English verdict.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of DuraFlex liner systems across New York City, from flexible gas liners in Long Island City condos to heavy-wall oil flue replacements in Park Slope brownstones. Their UL-listed products and comprehensive sizing charts let us specify exactly the right alloy and gauge for your application, and we stock common diameters and termination components on every truck.
HeatShield’s cerfractory technology - a ceramic-refractory hybrid - allows us to resurface clay flue tiles without removal in qualifying conditions, a significant cost savings for New York City homeowners with structurally sound but cracked liners. We’ve also worked extensively with Famco termination caps and Copperfield chimney supplies for proper flashing, sealing, and ventilation components. Whether you have DuraFlex, HeatShield, Famco, or any other make, we can help. Our relationships with these manufacturers mean warranty claims process smoothly and replacement parts arrive without delay.
Signs You Need Chimney Liner & Rebuild Right Now
- White efflorescence or spalling brick on the exterior. These indicate moisture penetration through compromised mortar joints or a failed crown, and in New York City’s freeze-thaw climate, the damage accelerates every winter. What starts as surface staining can progress to structural failure within two to three seasons if the water source isn’t addressed.
- Flakes or debris in the firebox or cleanout. Pieces of clay tile or mortar in your fireplace mean the flue liner is deteriorating, and those pieces are narrowing the passage that carries toxic gases out of your home. This condition demands immediate inspection - not next month, not after the holidays.
- Smoke or odors entering living spaces during appliance operation. Backdrafting signals a flue that is either blocked, improperly sized, or leaking into wall cavities through liner gaps. In tight New York City construction, this isn’t merely unpleasant - it’s a health hazard that requires professional diagnosis.
- Visible cracks in the flue tiles during routine cleaning. Even hairline cracks expand with thermal cycling, and cracked flue tiles cannot contain a chimney fire or prevent heat transfer to combustible framing. Our Level-2 camera inspection documents every crack with photos you can see and a plain-English verdict on whether repair or replacement is appropriate.
- Your heating appliance was converted to a different fuel without liner modification. Oil, gas, and solid fuel each produce different combustion byproducts and require liners rated for those specific conditions. An unmodified liner after fuel conversion is a code violation in New York City and a known factor in carbon monoxide incidents.

How Much Does Chimney Liner & Rebuild Cost in New York City?
A typical stainless steel liner installation in New York City runs $2,800-$4,500 for a straightforward gas or oil flue in a standard-height chimney. Flexible liner installations with offset navigation range $3,200-$5,000. HeatShield liner repair for qualifying clay flue tile conditions costs $1,800-$2,800. Partial rebuilds - crown, shoulders, and top courses - generally fall between $3,500 and $6,500. Full chimney rebuilds in New York City, including scaffolding, DOB permits, and proper weather protection, range from $8,500 to $15,000 depending on height, access, and masonry matching requirements.
Several factors move these numbers. Chimney height above roofline affects material quantities and scaffolding needs. Access constraints in dense neighborhoods like Chinatown or the East Village may require specialized equipment. Historic district work in Brooklyn Heights or Gramercy Park demands masonry matching that standard brickyards don’t stock. Fuel type matters too - oil flues require heavier-gauge liners than gas, and solid fuel demands the highest grade.
To avoid overpaying, get a Level-2 inspection with video documentation before accepting any proposal. We’ve provided free second opinions on written estimates that recommended full rebuilds when partial repairs would suffice, and we’ve caught underspecified liners that would have failed prematurely. Our estimates are free, detailed, and delivered with no obligation. Call (855) 950-3861 for yours.
