Our Chimney Liner & Rebuild Services in Gravesend
Stainless Steel Liner Installation
Gravesend’s 1920s-1940s brick homes, originally built with coal furnace flues, often have undersized or multilayered flue liners that require custom stainless steel relining to safely vent modern gas appliances. We recently relined a 1930s semi-detached on McDonald Avenue where the original terracotta liner had spalled from salt air and was too narrow for the new high-efficiency gas boiler. We installed a custom 6-inch DuraFlex stainless steel liner, sealed the old chase, and added a stainless cap to resist corrosion. The job took one day. The homeowner hasn’t thought about it since.
Stainless steel handles the temperature swings and corrosive byproducts of modern gas appliances better than any material we know. For Gravesend’s coastal climate, we specify corrosion-resistant grades and pair them with proper insulation to prevent condensation damage.
Flexible Liner Systems
Many Gravesend chimneys have offsets, corbels, or tight flue passages that rigid liners simply won’t navigate. A flexible stainless liner from our Chimney Liner & Rebuild team conforms to these irregular shapes while meeting all venting codes. This is especially common in the older homes near Avenue U, where chimney construction prioritized coal-era draft patterns over modern appliance requirements.
Flexible liners also solve the undersized flue problem. When a coal flue was converted to oil and then to gas, the passage often became too small for safe venting. A properly sized flexible liner restores adequate draft while protecting the surrounding masonry from acidic condensation.
Liner Replacement
Full liner replacement becomes necessary when terracotta has spalled beyond repair or when multiple cracks compromise the flue’s integrity. In Gravesend, salt-laden marine air accelerates this deterioration. We’ve replaced liners in homes on Shore Parkway where the terracotta had degraded to powder in under twenty years - half the lifespan you’d see in Flatbush or Borough Park.
Our replacement process includes camera documentation before and after, proper sizing calculations for your specific appliance, and installation using professional-grade materials from DuraFlex and Olympia Chimney. We don’t use builder-grade substitutes.
Partial and Full Chimney Rebuild
When the chimney structure itself has failed - spalling brick, deteriorated mortar, or a compromised crown - a new liner alone won’t solve the problem. Our Chimney Liner & Rebuild in Gravesend work includes partial rebuilds of damaged sections and full rebuilds when the structure is beyond salvage.
Full rebuilds are more common near the water, where nor’easters and salt spray attack masonry from the outside while flue gases attack from within. We match existing brick and mortar where possible, install proper flashing and crowns, and always integrate a new liner system sized for your current heating equipment.

We work exclusively with professional-grade materials: DuraFlex stainless liners, HeatShield resurfacing systems, Gelco caps and accessories, Olympia Chimney components, Famco venting products, and Copperfield masonry supplies. These are the brands specified by chimney professionals nationwide, not the substitutes you’ll find at big-box retailers. We stock common liner diameters and fittings locally, so Gravesend customers aren’t waiting weeks for parts. When your heat is out in January, that matters.
Common Chimney Liner & Rebuild Problems We See in Gravesend Homes
- Terracotta liners spall and crack from salt air. The marine environment near Coney Island penetrates mortar joints with salt-laden moisture, then freezes and expands. Terracotta surfaces flake off, exposing the rough interior to more creosote buildup and reducing draft efficiency. Spot repairs rarely last here; full relining is usually the sounder investment.
- Shared chimney chases between attached homes create clearance nightmares. On the residential blocks between McDonald Avenue and Ocean Parkway, one owner may maintain their flue while the neighbor neglects theirs for decades. The resulting creosote imbalance and shared masonry liability forces joint liner replacements that neither homeowner anticipated.
- Coal-to-gas conversion flues are dangerously undersized. Original flues designed for coal furnaces often measure 5 inches or less - inadequate for modern gas appliances that produce cooler, more moisture-laden exhaust. Without proper relining, these flues vent too slowly, leading to condensation damage and potential carbon monoxide hazards.
- Metal components rust through prematurely. Chimney caps, chase covers, and even some older metal liners corrode faster in Gravesend’s coastal air than manufacturers’ standard ratings predict. We specify stainless steel and copper for exposed components, and we inspect for hidden rust during every liner evaluation.
Pricing for Chimney Liner & Rebuild in Gravesend, NY
A typical flexible stainless steel liner installation in Gravesend runs $2,800-$4,500 for a standard single-flue residential chimney. Full stainless steel rigid liner systems with insulation range from $3,500-$5,800. Partial chimney rebuilds start around $4,200 and climb to $6,500 depending on height and accessibility. Full chimney rebuilds in Gravesend generally fall between $6,000 and $12,000, with the upper range reserved for multi-flue structures on taller homes or shared chases requiring coordinated work.
What moves the number: flue height, number of flues, whether the chimney is interior or exterior, accessibility from the roof or basement, and whether the existing liner can be removed or must be broken out. Shared chases between attached homes add coordination complexity.
We provide no-hassle upfront pricing. The number on the estimate is the number on the invoice. Estimates are free, and our $89 Seasonal Tune-Up includes a basic inspection that can catch liner problems before they become expensive. Seniors and veterans receive a permanent 5% discount.

FAQs - Chimney Liner & Rebuild in Gravesend
Salt-laden marine air from the Lower New York Bay penetrates mortar joints and accelerates spalling, cracking, and freeze-thaw damage to terracotta liners at rates noticeably higher than interior Brooklyn neighborhoods. The closer your home is to Coney Island’s coastline, the more aggressive this cycle becomes. Annual inspections are a practical necessity here, not a luxury. Call (855) 950-3861 to schedule - estimates are free.
Often no; original coal flues in Gravesend are typically too small and too rough-surfaced to safely vent modern gas appliances, and they may not meet current venting codes. We measure the flue, inspect the liner condition with a camera, and calculate proper sizing for your specific equipment. Most coal-era flues in this neighborhood require stainless steel relining for safe gas venting. Call (855) 950-3861 for an evaluation.
Yes, because abandoned or neglected flues in a shared chase can still compromise the entire structure through moisture intrusion, pest entry, or masonry deterioration that affects both units. We frequently encounter this on the semi-detached blocks between McDonald Avenue and Ocean Parkway, where one owner’s maintenance lapse creates liability for both. Coordinated relining protects both properties and often reduces per-unit cost. Call (855) 950-3861 to discuss shared chase solutions.
Stainless steel, specifically corrosion-resistant grades from DuraFlex or Olympia Chimney, outperforms all other options in salt-air environments like Gravesend. We avoid aluminum and standard galvanized products for liner applications here - they simply don’t last. Proper insulation and a quality stainless cap complete the system. Call (855) 950-3861 for material specifications for your chimney.
The original rebuild likely used a standard galvanized or lower-grade metal liner unsuited to Gravesend’s coastal salt exposure, or the liner was improperly sized for a gas appliance and condensation accelerated corrosion. We’ve replaced rusted liners in rebuilt chimneys throughout 11223. The fix is a proper stainless steel liner with correct sizing and insulation. We offer free second opinions on any written estimate you’ve received. Call (855) 950-3861.
