Fast, Reliable Chimney Liner & Rebuild Across Greenpoint
Chimney liner installation and chimney rebuilds in Greenpoint typically cost between $2,800 and $7,500 depending on whether we’re dropping a stainless steel liner into an existing flue or rebuilding a compromised stack from the roofline down. Most Greenpoint jobs are completed in a single day, and our Greenpoint crews carry flexible DuraFlex liners and rigid stainless components sized for the narrow flues common in 1880s-1910s rowhouses. Call (855) 950-3861 and a live person will answer, 24 hours a day.
We’ve worked on chimneys along Manhattan Avenue, Nassau Avenue, and the side streets stretching toward Newtown Creek for over 42 years. Greenpoint’s housing stock is unlike anywhere else in Brooklyn. The attached brick rowhouses and tenement walk-ups in the 11222 ZIP were built for coal heat, converted to gas or oil decades ago, and often never received proper flue relining. That leaves original terra cotta flue systems deteriorating inside walls that now serve modern appliances. We know the clearance constraints, the party-wall complications, and the parking headaches around McCarren Park. We’ll be there when we say.

Our Chimney Liner & Rebuild Services in Greenpoint
Stainless Steel Liner Installation
We install rigid and flexible stainless steel liners manufactured to UL 1777 standards, sized precisely for your appliance and flue. In Greenpoint’s pre-war rowhouses, we regularly encounter flue dimensions that don’t match modern standard sizes, leftover from coal-era construction. Our Olympia Chimney and DuraFlex components accommodate those irregular dimensions without forcing a poor fit. A properly sized stainless liner protects your masonry from corrosive flue gases and contains any chimney fire within the flue, preventing it from reaching the surrounding structure. Most Greenpoint installations run $3,200-$5,800 for a single-flue system.
Flexible Liner Installation
Flexible liners are often the only practical solution in Greenpoint’s offset flues, where the chimney throat doesn’t align vertically with the appliance below. These are common in converted tenements where a former coal boiler was replaced with a gas unit in a different position. We recently refined an original terra cotta flue system in a restored 1895 rowhouse on India Street near McCarren Park. The exposed waterfront winds had crumbled the mortar joints, causing dangerous backdrafting, and the abandoned coal-era cleanout door leaked carbon monoxide. We installed a flexible DuraFlex stainless steel liner sealing the shared party-wall stack with HeatShield cement, eliminating the downdraft and securing a safe chimney for the homeowner’s newly opened fireplace. Flexible liner jobs in Greenpoint typically range $2,800-$4,500.
Liner Replacement
When an existing liner has failed, collapsed, or been damaged by a chimney fire, full replacement is necessary. In Greenpoint, we see this frequently in buildings where a clay tile liner was installed during a 1970s conversion but has since cracked from thermal shock or settled out of alignment. Our replacement process includes full camera documentation of the damage, debris removal, and installation of a new system with proper insulation where required by code. We handle the NYC DOB filing when a permit is triggered by the scope of work. Replacement projects generally fall between $3,500 and $6,200.
Partial Chimney Rebuild
When the flue is sound but the surrounding masonry has deteriorated, we rebuild the affected section, typically from the roofline up or around a damaged crown. Greenpoint’s persistent waterfront winds accelerate mortar joint erosion on chimney crowns and caps, making this a common need near the East River. We match existing brick where possible and install a proper concrete crown with positive drainage to prevent future water intrusion. Partial rebuilds in Greenpoint run $4,200-$7,500 depending on height and accessibility.
Full Chimney Rebuild
For chimneys with systemic structural failure, multiple flue collapses, or severe water damage throughout the stack, we rebuild from the foundation up. This is more common in Greenpoint than many homeowners expect, particularly in buildings where a shared party-wall stack has been neglected by multiple owners. Full rebuilds require careful staging in tight alley-load conditions, coordination with adjoining building owners when party walls are involved, and full DOB permitting. These projects range $8,500-$15,000 and typically take 3-5 days.

Trusted Brands We Service in Greenpoint
We stock components from Gelco, Olympia Chimney, and Famco in our local warehouse, which means we’re not waiting on freight when your Greenpoint chimney needs attention. DuraFlex flexible liners handle the offset flues common in converted tenements. HeatShield cerfractory cement repairs deteriorating terra cotta without full replacement when conditions allow. We don’t use builder-grade substitutes. The materials we install are the same ones specified by chimney engineers for commercial applications. That matters in a neighborhood where you’re likely sharing a wall with someone else’s flue.
Common Chimney Liner & Rebuild Problems We See in Greenpoint Homes
- Unlined coal-era flues crumbling from waterfront exposure. Greenpoint sits on a peninsula bounded by the East River to the west and Newtown Creek to the north. Persistent waterfront winds accelerate mortar joint erosion in original terra cotta flues, leading to backdrafting and carbon monoxide intrusion into living spaces. We address this with properly insulated stainless liners and sealed crowns.
- Shared party-wall stacks creating liability confusion. Many Greenpoint rowhouses share chimney stacks serving two or three adjoining buildings. One owner’s neglected, debris-filled flue can deposit creosote or blockages into an active neighboring flue. NYC Local Law places cleaning and maintenance responsibility squarely on building owners. Our Chimney Liner & Rebuild team documents party-wall conditions and coordinates with adjoining owners when necessary.
- Tight access delaying material delivery. Alley-load doors and narrow townhome entries in Greenpoint require staging plans for heavy liner materials. Without preparation, projects run over schedule. We measure access points during inspection and plan delivery accordingly.
- New owners reopening fireplaces sealed for decades. Rapid gentrification means new Greenpoint homeowners regularly unseal fireplaces that haven’t been inspected in 30-50 years. Original flues designed for coal are often unlined, deteriorated, and improperly sized for modern gas inserts or wood-burning appliances. Camera inspection before first use is essential.

FAQs - Chimney Liner & Rebuild in Greenpoint
We seal the common wall between flues with HeatShield cerfractory cement or a proper partition plate before installing your new liner, preventing cross-contamination between active and inactive flues. Our inspection includes camera documentation of the party-wall condition, and we’ll coordinate with your adjoining owner if their flue requires attention. This is standard practice for our Greenpoint jobs on India Street, Nassau Avenue, and the side streets near McCarren Park. Call (855) 950-3861 to schedule an inspection.
Yes, in most cases we install a flexible or rigid stainless steel liner through the existing flue without disturbing the surrounding brickwork. We recently completed this exact procedure on a 1902 tenement walk-up near Manhattan Avenue, threading a DuraFlex liner down an offset flue that had served a coal boiler until 1987. The brick stack remained intact. Full removal is only necessary when the masonry itself has failed structurally. Call (855) 950-3861 for a camera inspection to confirm your flue’s condition.
Greenpoint’s exposed peninsula location puts chimney crowns directly in the path of prevailing westerly and northerly winds, which pressurize the flue top and force smoke backward. Crumbled mortar joints from years of wind-driven rain make this worse by destroying the chimney’s natural draft. We correct this with a properly insulated liner, a sealed crown with positive drainage, and when necessary, a code-approved draft-inducing cap. The difference is immediate and measurable. Call (855) 950-3861 for an assessment.
A permit is required for any chimney rebuild involving structural masonry, and for liner installations where the appliance type is being changed or where the work affects a party wall. We handle all DOB filings as part of our service. For straightforward like-for-like liner replacements in single-family rowhouses, the work may proceed without permit, but we document everything to Local Law standards regardless. We’ll tell you exactly what your specific job requires before any work begins. Call (855) 950-3861 to discuss your situation.
No, and you should not use a chimney with a shared flue under any circumstances. NYC code prohibits shared flues for solid fuel and requires separation for gas appliances in most configurations. If your Greenpoint rowhouse has a true shared flue, we install a partition and separate liners, or rebuild to create independent flues. This is non-negotiable from both a safety and code compliance standpoint. Call (855) 950-3861 for a proper evaluation.
