Fast, Reliable Chimney Liner & Rebuild Across Chinatown
Chimney liner repair and full rebuilds in Chinatown, NY typically run $2,800–$8,500 depending on whether we’re relining a single residential flue or rebuilding a shared tenement stack, and Robert Garcia usually has a crew on-site within 24–48 hours of your call. We know the 10013 ZIP well — from the five-story brick tenements lining Mott Street to the mixed-use buildings where restaurant exhaust and residential heating share the same century-old chimney chase. If you’re smelling smoke in your apartment, seeing grease stains on your flue walls, or running a kitchen with a wok burner connected to a flue built for coal stoves, we need to inspect it before heating season hits. Call (866) 884-9512.
Our Chimney Liner & Rebuild team has worked Chinatown’s unique building stock for 17 years. We’ve pulled fractured terra-cotta from flues that vented Sichuan kitchens, installed grease-rated stainless steel liners in buildings where the original coal-burning diameter couldn’t handle 150,000 BTU wok output, and repointed crowns above rooftops taking direct salt spray from the East River. This isn’t generic chimney work — it’s specialized knowledge of a neighborhood where one neglected flue puts multiple families at risk.
Why Apex Chimney Cleaning Greater New York Is Chinatown’s Preferred Chimney Liner & Rebuild Company
We’ve earned our reputation in Chinatown one building at a time. Robert Garcia, the owner, handles the work himself — not a dispatched subcontractor who needs directions to Canal Street. When you call (866) 884-9512, you’re talking to the person who’ll be on your roof, making the call on whether a flue can be relined or if the whole stack needs to come down to the roofline.
Our 1,096 verified reviews averaging 4.7 stars include dozens from Chinatown property owners and restaurant operators who needed someone who understood tenement flue sharing, grease-duct code requirements, and the Department of Buildings’ stance on mixed-use chimney configurations. They didn’t want the lowest bidder — they wanted the problem solved correctly the first time, with documentation that satisfied their insurance and their upstairs tenants.
Response time to Chinatown averages same-day or next-day during peak season, because we’re based in New York City and don’t route crews from Queens or New Jersey. We know which buildings on Doyers Street have original 1880s flues, which Mott Street properties were retrofitted with gas in the 1960s without proper liner upgrades, and how to navigate the tight roof access and shared airshaft configurations that make tenement chimney work mechanically challenging.
Our Chimney Liner & Rebuild Services in Chinatown
Stainless Steel Liner Installation
For Chinatown’s high-BTU commercial kitchens and the residential flues they too often share, we install grease-rated 316Ti stainless steel liners that can handle corrosive cooking exhaust without the degradation you’d see in standard residential-grade material. A typical stainless steel liner installation in Chinatown runs $3,200–$5,800 for a residential flue, $4,500–$8,500 for a commercial grease-rated installation with proper insulation and cleanout access. We size these specifically — a 6-inch diameter for most residential heating appliances, stepping up to 8-inch or custom for wok-burner exhaust that would choke in a narrow original flue.
The stainless steel option matters especially in Chinatown because polymerized grease at 600°F+ will destroy clay or aluminum liners within a season. We’ve replaced “budget” liners that failed in eight months because they weren’t spec’d for the actual load. We use DuraFlex and Olympia Chimney product lines — the same materials commercial kitchen contractors specify — and we document the installation for your fire insurance and DOB records.
Flexible Liner Installation
Chimney flues in Chinatown’s tenements rarely run straight. Offset flues, corbelled construction, and the structural compromises of 140 years of settlement mean a rigid liner often won’t pass. Our flexible liner installations — typically $2,800–$4,900 in Chinatown — use corrugated 316Ti stainless that navigates offsets while maintaining draft efficiency.
Robert Garcia assesses each flue with a video scan before recommending flexible versus rigid. In buildings near the Sniffen Court Historic District and throughout 10013, we’ve encountered flues with three-foot lateral offsets where rigid pipe was simply impossible. The flexible option also allows us to pull liners through from the roof without dismantling interior plaster — critical in occupied tenements where tenants can’t be displaced for masonry demolition.
Liner Replacement
When a liner is cracked, open-jointed, or grease-saturated beyond cleaning, replacement is the only code-compliant path. Liner replacement in Chinatown typically costs $3,500–$6,200, with commercial grease-duct replacements at the higher end due to insulation and access requirements.
We see this need constantly in Chinatown’s mixed-use buildings. A restaurant on the ground floor of a five-story tenement may have operated for years with a flue that was “working fine” — meaning the grease was migrating through open joints into the residential heating flue above, slowly coating it with combustible residue. By the time upstairs tenants smell cooking oil in their apartments, the shared flue is a Class K fire hazard requiring complete replacement, not repair. We document the cross-contamination with video evidence, replace with dedicated separate liners where code allows, and coordinate with your restaurant exhaust contractor if a dedicated grease duct needs to be routed independently.
Partial Rebuild
Not every failing chimney needs to come down to the foundation. Partial rebuilds — typically $4,200–$7,800 in Chinatown — address the section from the roofline up, where salt air, freeze-thaw cycling, and failed crown flashing have destroyed the flue liner and surrounding masonry while the lower stack remains sound.
Chinatown’s exposed rooftop stacks take the worst of it. Buildings within two blocks of the East River — which includes much of the area south of Canal Street — see accelerated spalling where salt-laden air drives moisture deep into mortar joints. The crown cracks, water enters, freeze-thaw opens the flue liner below, and suddenly you’ve got a chimney that drafts poorly, leaks into apartments, or channels carbon monoxide into living spaces. Our partial rebuilds replace the damaged upper section with matching brick, install a proper concrete crown with drip edge and sulfate-resistant mortar, and tie in a new liner to the sound lower flue.
Full Chimney Rebuild
When the original terra-cotta liner has fractured throughout the stack, when multiple flues in a shared chase have cross-contaminated, or when structural integrity is compromised, we rebuild from the roofline down or foundation up. Full rebuilds in Chinatown’s tenements range $8,500–$18,000 depending on height, access, and whether we’re rebuilding one flue or a multi-flue chase serving multiple units.
Our crew handled a full chimney rebuild on a five-story tenement at 25 Bowery, where the original terra-cotta liner had fractured from decades of thermal cycling from a ground-floor Sichuan kitchen. We extracted sections of the old liner, installed a 6-inch DuraFlex flexible stainless steel liner tied into the remaining stack, and repointed the crown with sulfate-resistant mortar to withstand the East River salt air. The owner saw a 40% drop in upstairs smoke complaints.

Trusted Brands We Service in Chinatown
We install professional-grade materials because Chinatown’s flue conditions destroy inferior product. Our stock includes DuraFlex flexible liners for offset tenement flues, HeatShield cerfractory resurfacing for select clay liner restorations, and Gelco stainless steel components for caps and connectors. We don’t order from a catalog when you call — we carry common diameters and fittings on our trucks, which means faster turnaround on Chinatown jobs where a failed flue may have shut down a restaurant or left a residential unit without heat. When we need specialty sizes for the narrow coal-era flues found in pre-1900 tenements, our supplier relationships with Copperfield and Famco get us parts in 24 hours, not a week.
Common Chimney Liner & Rebuild Problems We See in Chinatown Homes
- Restaurant grease migrating through open joints into residential flues. In Chinatown’s mixed-use tenements, a ground-floor kitchen’s exhaust often shares a masonry chase with upstairs heating flues. When original clay liners crack or joints open, aerosolized grease migrates laterally — creating a fire hazard in a flue that should contain only heating exhaust. We find this in buildings throughout 10013 where restaurant retrofits never included dedicated grease ducts.
- Salt-laden harbor air destroying exposed rooftop masonry. Chinatown’s proximity to the East River means constant salt exposure on chimney crowns and upper brickwork. Spalling accelerates, mortar fails, and water enters the flue system. Annual inspection catches this before winter freeze-thaw cycles drive cracks deep enough to require full rebuild rather than crown repair.
- Original coal-era flue diameter incompatible with modern appliances. Many Chinatown tenements were built with 5-inch or 6-inch flues designed for coal stoves. A modern 150,000 BTU wok burner or high-efficiency gas furnace needs 7-inch or 8-inch diameter to draft properly. The mismatch causes chronic backdraft, carbon monoxide risk, and failed inspections. Relining with properly sized stainless steel is the only fix.
- Polymerized grease accumulation in “borrowed” flues. Local technicians know to flag any Chinatown building where a restaurant has been added to a lower floor in recent decades: the cooking exhaust was often connected to whatever existing flue was available rather than a dedicated grease duct, meaning a chimney sweep may open a flue expecting heating residue and instead find a solid coating of polymerized wok grease — a Class K fire hazard that requires degreasing agents and specialized brushes, not a standard sweep.

We don’t guess — we video-scan, quote exact scope, and stand by the number. Estimates are free. Call (866) 884-9512.
In Chinatown specifically, we’ve found that buildings with active restaurant exhaust sharing residential flues almost always require more extensive work than initially apparent — the visible problem is rarely the only problem. Our quotes include full chase inspection so you’re not surprised by a second flue failure six months later.

FAQs — Chimney Liner & Rebuild in Chinatown
No — inserting a liner into a grease-contaminated shared flue without addressing cross-connections and separation violates NYC fire code and leaves the residential flues at risk. We need to video-scan the full chase, identify all active flues, and typically install dedicated liners with proper separation and insulation. In most Chinatown tenements, this means a grease-rated stainless liner for your kitchen exhaust and separate properly sized liners for residential heating appliances above. Call (866) 884-9512 for a free inspection and exact scope.
Salt-laden air accelerates spalling and mortar deterioration in exposed brick chimney stacks, which then allows water infiltration that cracks clay liners below the roofline — a failure mode we see far more frequently in Chinatown and the Financial District than in inland Manhattan neighborhoods. The salt doesn’t directly attack stainless steel liners, but it destroys the masonry that supports and protects them. We specify sulfate-resistant mortar and proper crown overhangs on Chinatown rebuilds to slow this degradation.
For residential heating flues with minor cracking and no grease contamination, HeatShield cerfractory resurfacing can extend service life 10–15 years at roughly half the cost of full replacement. But in Chinatown’s mixed-use buildings, we rarely recommend repair over replacement — the combination of thermal cycling from modern appliances, grease migration through open joints, and 140 years of material fatigue means patched liners fail again within 2–4 years. We show you the video scan and quote both options honestly.
Expect that the existing flue was sized for residential heating or small commercial use, not high-BTU wok burners, and that it may share a chase with upstairs units. You’ll likely need a dedicated grease-rated liner sized for your total appliance load, possible chase modification for proper separation from residential flues, and DOB approval of the exhaust configuration. We coordinate with your kitchen contractor and expediter to get the chimney scope defined early — it’s the critical path item that delays more Chinatown restaurant openings than any other trade.
Partial rebuild addresses the chimney from the roofline up — crown, upper brick, and top flue section — when the lower stack is structurally sound and the liner below is intact. Full rebuild is required when the original terra-cotta liner has fractured throughout, multiple flues in the chase have cross-contaminated, or settlement damage has compromised structural integrity. In Chinatown’s five- and six-story tenements, partial rebuilds are more common; full rebuilds typically follow years of deferred maintenance or catastrophic grease fires. Robert Garcia assesses each with video scan and structural evaluation before recommending scope.
