What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a rigid or corrugated metal flue insert that protects your chimney walls from corrosive flue gases and contains heat safely. In Greater New York, we install stainless steel liners in homes where clay flue tiles have cracked from decades of thermal cycling or where a gas appliance conversion requires a properly sized venting path. Robert measures every flue himself on-site—no guesswork from a subcontractor—to spec the correct diameter and length, then installs it with proper insulation and top-sealing to meet NFPA 211 standards for our climate.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that navigate offset flues, chimney bends, or tight clearances where rigid pipe won’t fit. We use flexible liners frequently in Gramercy Park and Hell’s Kitchen row houses where original construction left minimal space between the flue and masonry. Robert’s 17 years of hands-on experience means he can assess whether your chimney’s offset is within the bending radius of a quality flexible product, avoiding the installation failures we’ve seen from crews who force incompatible materials into tight spaces.
Liner Replacement
Liner replacement becomes necessary when your existing liner—whether clay, metal, or poured refractory—has deteriorated to the point of creating safety hazards like carbon monoxide leakage or creosote buildup in wall gaps. In Hollis and East Flatbush, we regularly replace liners that failed prematurely due to improper original sizing or moisture intrusion from missing chimney caps. We remove the damaged liner completely, inspect the surrounding masonry for hidden decay, and install a new system sized precisely for your appliance type and BTU output.
Partial Rebuild
A partial rebuild addresses structural failure limited to a specific section of your chimney—often the top few feet of brickwork, the crown, or one wall that’s spalled from water infiltration. Kensington homeowners call us when they notice their chimney crown has cracked and water is working down through the brick freeze-thaw cycle, compromising the liner below. Robert rebuilds only what’s necessary, matching existing mortar color and brick coursing where possible, then integrates the new masonry with a properly flashed and capped liner system to prevent recurrence.
Full Chimney Rebuild
Full chimney rebuilds are required when structural integrity has failed across multiple walls, the foundation has settled, or a lightning strike or vehicle impact has caused catastrophic damage. We’ve completed full rebuilds in Briarwood and Uniondale where decades of deferred maintenance left chimneys leaning or separating from the house frame. Robert manages the entire project—from safe demolition and debris removal to engineered rebuild with proper footings, flue sizing, and weatherproofing—so you’re not coordinating between a mason, a liner installer, and a cap specialist.
Liner Repair
Liner repair targets localized damage like small cracks, joint gaps, or surface spalling that hasn’t yet compromised the entire system. In East Village pre-war buildings where full liner replacement would require extensive scaffolding and landmark considerations, we often recommend targeted repair using HeatShield or similar professional-grade refractory products. Robert evaluates whether repair is genuinely viable—he’s seen too many “repairs” that masked underlying failure—or if replacement is the honest recommendation, and he’ll explain exactly why in terms you can verify.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced HeatShield systems in dozens of Greater New York homes where poured refractory liner restoration was the right solution for preserving historic flue dimensions while sealing gaps and cracks. Our experience with HeatShield goes beyond application—we understand when the product is appropriate versus when its limitations would leave a customer with a temporary fix on a fundamentally failing system. We also work extensively with Gelco liner components and accessories, stocking common sizes and termination caps so we’re not waiting on supply house orders when your project is underway.
Olympia Chimney and Famco products round out our material inventory, with Olympia’s flexible and rigid stainless steel lines serving many of our Brooklyn and Flatbush installations where corrosion resistance and proper draft performance are critical. Whether your existing system was originally built with one of these brands or you’re comparing options for a new installation, Robert will walk you through the specific advantages and trade-offs for your chimney configuration and appliance type. And if your chimney has another manufacturer’s components—DuraFlex, Copperfield, or a brand we haven’t named—we’ve encountered enough variety over 1,000-plus jobs to service it properly or recommend a compatible replacement.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means moisture is moving through your chimney walls, dissolving salts, and depositing them on the surface. In Greater New York’s wet winters, this signals that your liner may be leaking flue gases or that your crown has failed, allowing water to saturate the masonry from above. Left unaddressed, the freeze-thaw cycle will spall brick faces and deteriorate mortar joints until partial or full rebuild becomes unavoidable.
- Flaking or crumbling clay pieces in your firebox or cleanout indicates that your clay flue tiles are spalling from the inside, often due to thermal shock or acid corrosion from condensed flue gases. We’ve found this in Briarwood homes with original 1950s clay liners that were never designed for modern appliance temperatures. Once tiles begin shedding material, the liner’s protective function is compromised and replacement should be scheduled before the next heating season.
- Smoke or odors entering living spaces when the fireplace isn’t in use suggests liner gaps, improper sizing, or negative pressure issues that allow downdrafts to push chimney air into your home. In tightly sealed Uniondale and Hillside homes built or retrofitted for energy efficiency, this problem has become more common as houses compete with chimneys for makeup air. A properly sized and sealed liner, combined with adequate combustion air, typically resolves this completely.
- Visible cracks in your chimney crown or missing mortar between bricks creates pathways for water that will destroy your liner from the outside in. Robert inspects crowns on every liner job because we’ve learned that installing a premium liner beneath a failed crown is simply preparing for a callback. Crown repair or replacement is often bundled with liner work to protect your investment.
- Your home inspection flagged the chimney, or your insurance requires documentation means you need a qualified evaluation now, not next season. We’ve completed emergency assessments for real estate closings in Hollis and East Flatbush where a failed chimney inspection threatened to derail a sale. Robert provides written documentation of liner condition, recommended repairs, and completed work that satisfies mortgage underwriters and insurance underwriters alike.
Our Chimney Liner & Rebuild Process — Step by Step
- 1
On-site inspection and video scan. Robert arrives at your Greater New York home with a chimney video inspection camera that records the full length of your flue in high definition. You’ll see exactly what we see—cracks, gaps, glaze buildup, or structural anomalies—on a monitor in real time. This eliminates guesswork and provides documentation for insurance or real estate purposes if needed.
- 2
Detailed diagnosis and transparent estimate. We explain what’s failing, why it’s failing, and what options exist for repair versus replacement versus rebuild. Our estimates itemize materials, labor, and any necessary ancillary work like crown repair or flashing replacement. You’ll know the full scope before any work begins—no surprises, no upsells.
- 3
Material selection and scheduling. Based on your chimney’s dimensions, appliance type, and your preferences, we specify the appropriate liner material and brand. For stainless steel installations, we confirm gauge and alloy grade; for flexible liners, we verify bending radius compatibility with your flue path. We schedule work around your availability and weather windows, with most liner projects completed in a single day.
- 4
Professional installation with owner oversight. Robert performs or directly supervises every installation, ensuring proper clearances, insulation where required by code, and secure top and bottom terminations. For rebuilds, he manages demolition sequencing, debris containment, and masonry work to minimize disruption to your household and property.
- 5
Final inspection, documentation, and cleanup. We video-scan again after installation to verify proper placement and integrity. You’ll receive written documentation of completed work, material specifications, and any applicable warranty information. We leave your property clean—swept, vacuumed, and ready for safe use.
How Much Does Chimney Liner & Rebuild Cost in Greater New York?
A typical stainless steel liner installation in Greater New York runs $2,800–$4,500 for a standard single-flue chimney with straightforward access and no masonry repair. Flexible liner installations in tight offset flues, common in older Brooklyn and East Village construction, range $3,200–$5,000 due to additional labor and specialized fitting requirements. Liner replacement where the existing system must be extracted before new installation falls in the $3,500–$5,500 range depending on accessibility and disposal complexity.
Partial rebuilds addressing crown and upper masonry failure typically cost $4,000–$6,500 in our market, while full chimney rebuilds—demolition through completed structure with new liner—range from $8,000 to $15,000+ depending on height, accessibility, and whether scaffolding or crane work is required. Liner repair using professional-grade refractory products like HeatShield starts around $1,800–$2,800 when the damage is genuinely localized and the underlying structure is sound.

Several factors move these numbers: chimney height and roof pitch (steeper = more safety equipment and labor), number of flues being lined, whether your appliance conversion requires resizing, and the condition of surrounding masonry that must be sound before a liner is installed. The biggest variable we see is deferred maintenance—catching crown cracks early prevents the $6,000 rebuild that becomes necessary after five more winters of water intrusion.

Frequently Asked Questions — Chimney Liner & Rebuild in Greater New York
Chimney liner and rebuild work involves either installing or repairing the protective flue lining that contains combustion gases, or reconstructing damaged chimney masonry when structural integrity has failed. The liner prevents heat transfer to combustible framing, protects masonry from corrosive byproducts, and ensures proper draft for your appliance. Rebuild work addresses the brick, block, or stone structure itself when cracking, spalling, or settling has compromised safety or function.
Most stainless steel or flexible liner installations are completed in one day; full chimney rebuilds typically require 2–4 days depending on weather and structural complexity. Partial rebuilds and liner replacements with masonry repair fall in between, often 1–2 days. We schedule with buffer for unexpected conditions—like finding hidden water damage during demolition—so you’re not left with an open flue overnight.
Chimney liner installation in Greater New York generally ranges from $2,800 to $5,500 depending on material and access, while rebuilds start around $4,000 for partial work and $8,000+ for full reconstruction. The specific price depends on chimney height, number of flues, appliance type, and masonry condition. Call (866) 884-9512 for an exact quote—estimates are free and include full scope documentation.
