When you call Hearthstone Chimney Co., you’re not getting a dispatcher from out of state. You’re getting technicians who’ve stood on roofs in Parkchester in February and who understand why a 1920s chimney built for coal behaves differently than one built for gas.

Our Chimney Liner & Rebuild Services in The Bronx
Stainless Steel Liner Installation
A stainless steel liner is the most durable solution for The Bronx’s aging chimneys, especially in 10462’s pre-war multi-family buildings where original clay tile has cracked from decades of thermal cycling. We install DuraFlex flexible stainless steel liners that conform to irregular flue shapes common in converted coal-era chimneys. A typical stainless steel liner installation in The Bronx runs $2,800-$4,500 for a single flue, including removal of damaged clay tile and proper sizing for your current appliance.
Flexible Liner Solutions
Flexible liners solve the offset and dimensional problems we constantly encounter in The Bronx’s attached brick rowhouses, where flues often shift or narrow between floors. Our Chimney Liner & Rebuild technicians use DuraFlex flexible stainless steel to navigate these irregular channels without destructive demolition. Flexible liner installation in The Bronx typically costs $2,400-$3,800.
Liner Replacement
When clay tile liners have deteriorated beyond repair, full replacement is the only safe option. In The Bronx, this scenario is common after oil-to-gas conversions left oversized flues unlined, a violation NYC’s Department of Buildings now actively flags during inspections. Under NYC’s phased ban on No. 4 and No. 6 heating oil starting around 2011, thousands of Bronx multi-family buildings converted boilers to gas, but many left the original oversized oil-era flues unlined for the new gas appliances. This is now one of the most frequent compliance-driven service calls we receive in ZIP 10462. Liner replacement in The Bronx runs $3,200-$5,500 depending on flue height and access.
Partial Chimney Rebuild
The Bronx’s repeated winter freeze-thaw cycles, temperatures frequently crossing the freezing threshold, aggressively deteriorate mortar joints and brick crowns on the borough’s abundant pre-war masonry chimneys. When spalling brick and crumbling mortar extend beyond the flue itself, partial rebuild restores structural integrity. We rebuild from the roofline up, matching existing brick and installing a proper concrete crown with expansion joints. Partial rebuilds in The Bronx typically range from $4,500-$7,500.
Liner Repair
Not every damaged liner needs full replacement. For localized cracks and gaps in otherwise sound clay tile, we apply HeatShield cerfractory sealant, a professional-grade refractory compound that restores flue integrity without full demolition. Liner repair in The Bronx costs $1,800-$2,800 and is often sufficient for chimneys with limited, accessible damage.
Full Chimney Rebuild
When a chimney has suffered catastrophic structural failure, complete rebuild from the foundation up may be necessary. This is less common in The Bronx than partial rebuilds, but we have completed full reconstructions on century-old rowhouses where neglect and water infiltration compromised the entire stack. Full rebuilds in The Bronx start around $8,500 and are quoted individually after Level-2 camera inspection.

Common Chimney Liner & Rebuild Problems We See in The Bronx Homes
- Cracked clay-tile liners from decades of freeze-thaw cycles. The Bronx’s winters repeatedly freeze and thaw the masonry in its pre-war chimneys, fracturing original clay tile and creating pathways for dangerous gases. We regularly find this in Morris Park and Van Nest rowhouses, where partial rebuild with stainless steel relining is the lasting fix.
- Oversized flues from oil-era conversions left unlined for new gas appliances. After NYC’s heating oil ban, many Bronx buildings installed gas boilers without resizing or lining the original oil-era flues. These oversized channels vent improperly, create condensation damage, and draw DOB violations. Relining to the correct dimension for gas appliances is now standard compliance work in 10462.
- Spalling mortar joints and failed crowns on attached brick rowhouses. Water infiltration through cracked crowns and open mortar joints accelerates deterioration throughout the chimney structure. In Parkchester’s dense multi-family buildings, one failed crown can affect multiple flues in a shared stack.
- Abandoned or repurposed flues in converted coal-era buildings. Original coal flues were often abandoned in place or repurposed without proper lining when buildings converted to oil, then gas. These orphaned channels create backdraft hazards and code violations that surface during routine inspections or real estate transactions.

FAQs - Chimney Liner & Rebuild in The Bronx
NYC’s phased ban on heavy heating oils forced thousands of Bronx buildings to convert boilers to gas starting around 2011, but many installers left original oversized oil-era flues unlined for the new appliances. NYC’s Department of Buildings now actively flags this violation during inspections, making chimney relining one of the most common compliance-driven service calls in ZIP 10462. If your building converted fuel types in the last fifteen years and you have no documentation of relining, your flue likely needs attention. Call (855) 950-3861 for a free inspection and written estimate.
The Bronx’s temperatures frequently cross the freezing threshold in winter, causing moisture trapped in masonry to expand and contract repeatedly. This process cracks clay tile liners, opens mortar joints, and spalls brick faces, accelerating deterioration that would take decades in milder climates. Annual inspection catches this damage before it requires full rebuild. We include crown and mortar assessment in every Level-2 inspection we perform in The Bronx.
Localized cracks and gaps can often be repaired with HeatShield cerfractory sealant, a professional-grade refractory compound that restores flue integrity at roughly half the cost of full replacement. However, if the tile is extensively fractured, shifted, or if the flue is improperly sized for your current appliance, replacement with a stainless steel liner is the correct and lasting solution. We document the condition with photos and give you a plain-English verdict, not a sales pitch. Call (855) 950-3861 to schedule camera inspection.
Morris Park, Van Nest, and Parkchester contain the highest concentration of 1920s-1940s attached brick rowhouses and low-rise multi-family buildings in this ZIP, most with original shared masonry chimney stacks serving multiple flue channels. The density of aging shared-flue infrastructure in these neighborhoods is specific to The Bronx and largely absent in surrounding suburban markets. We encounter deteriorated clay-tile liners, abandoned conversion flues, and failed crown caps more frequently here than in any other part of our service area.
An oversized flue for a gas appliance will show visible condensation staining, poor draft performance, or sulfuric acid damage to mortar joints, but the only definitive assessment comes from Level-2 camera inspection with proper measurement. In The Bronx, we regularly find 12×12 or larger oil-era flues serving modern gas boilers that require 6-inch or 7-inch liners for safe, efficient venting. If your building converted from oil to gas and no liner was installed, your flue is almost certainly out of specification. We measure, document with photos, and provide a written compliance plan. Estimates are free; call (855) 950-3861.
