We’ve been working in Larchmont since 1984, long enough to know the village’s chimneys house by house. The pre-WWII stock in Larchmont Manor, the salt-beaten exposures along Long Island Sound, the oversized flues left behind when homeowners switched fuels in the 1950s and 60s, these aren’t abstract problems to us. We’ve documented them with camera inspections, explained them in plain English, and fixed them with materials that match the original craftsmanship. Our Chimney Liner & Rebuild team knows that a Larchmont chimney isn’t a generic stack of brick. It’s a 90-year-old system under specific coastal stress, and it deserves repair by people who understand that context.
Why Hearthstone Chimney Co. of New York City Is Larchmont’s Preferred Chimney Liner & Rebuild Company
Larchmont homeowners call us because we’ve earned a reputation for showing up when we say we will, documenting what we find, and standing behind the result. Over 42 years, we’ve built that reputation one chimney at a time, from the Tudor Revivals along Forest Avenue to the Colonials near Flint Park. Our technicians are background-checked, uniformed, and trained to complete most liner and rebuild jobs in a single visit, no callbacks, no runarounds.
We answer the phone with a live person, every hour of every day. Not a voicemail tree. Not an app. A real person who can dispatch a technician to Larchmont, schedule your Level-2 camera inspection, or talk through what you’re seeing on your roof after last night’s nor’easter. Our 90-Day Done Right Promise is in writing, no arguing, if it’s not right, we come back and make it right. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Our estimates come with no-hassle upfront pricing. The number we give you is the number on the invoice. We’ve found that Larchmont homeowners, many of whom have been in their houses for twenty or thirty years, value that square deal more than a lowball quote that balloons once work begins. Photos you can see, a plain-English verdict, a price that doesn’t shift, that’s how we’ve stayed in business since 1984.
Our Chimney Liner & Rebuild Services in Larchmont
Stainless Steel Liner Installation
A stainless steel liner is the standard correction for Larchmont’s unlined or deteriorated terra cotta flues. We install DuraFlex and Olympia Chimney stainless systems, sized precisely to your appliance and your chimney’s interior dimensions. In Larchmont Manor Victorians, where original coal flues were often 12×12 inches or larger, a properly sized liner insert brings the flue into modern code compliance while preserving the exterior masonry. We recently relined a 1920s Tudor Revival in Larchmont Manor where the original coal-era flue had been jury-rigged for a gas furnace without a liner. The terra cotta was shattered in three places, so we installed a DuraFlex stainless steel liner and rebuilt the crown with a copper cap to resist Sound-driven corrosion. The job took one day. The homeowner had photos, a written verdict, and a 90-Day Done Right Promise before we left.

Flexible Liner Systems
Some Larchmont chimneys have offset flues, tight cleanouts, or structural bends that make rigid stainless impossible to insert. For these, we use flexible alloy liners from trusted manufacturers, navigated into place with specialized equipment and camera verification at every joint. Flexible liners are particularly useful in the older homes near Boston Post Road, where chimney throats were built for coal grates and modern inserts require a navigable path. We don’t guess. We camera-verify the full length before we call the job done.

Liner Replacement
When an existing liner, whether terra cotta, clay, or an older metal insert, has failed beyond repair, full replacement is the only safe option. In Larchmont, we see this most often in homes that had a mid-century fuel conversion, oil to gas, coal to oil, where the original liner was never properly sized for the new appliance. The result is an oversized, unlined flue that accumulates condensation, erodes mortar, and fails Westchester County inspection during a home sale. Our liner replacement includes removal of the failed material, thorough flue cleaning, precise measurement, and installation of a new system with proper insulation and connectors. Most Larchmont liner replacements run $3,200-$5,800 for a single-flue system.

Partial Chimney Rebuild
Salt-laden nor’easters accelerate spalling of soft historic brick in Larchmont, often requiring partial rebuild before a liner can even be inserted. We rebuild from the roofline up, or section by section, using matching brick and mortar where possible, and we always address the underlying moisture issue with proper crown slope, waterproofing, and cap installation. A partial rebuild in Larchmont typically ranges from $2,800-$4,500, depending on height and accessibility. We don’t rebuild what doesn’t need rebuilding, and we won’t install a liner into masonry that’s too deteriorated to support it. That’s the honest assessment our customers expect.

Trusted Brands We Service in Larchmont
We work exclusively with professional-grade materials from manufacturers who back their products the way we back our work. For Larchmont’s coastal conditions, we specify DuraFlex stainless liners for their corrosion resistance, Gelco and Famco caps and crowns for their durability against salt-air exposure, and Olympia Chimney components where code requires specific listings. We stock common sizes and configurations locally, so most Larchmont jobs don’t wait on parts. When a nor’easter has driven moisture into your flue cavity and you’re seeing rust stains on the brick, you don’t want a two-week delay for a specialty fitting. We keep the inventory that Larchmont’s older chimneys demand.
Common Chimney Liner & Rebuild Problems We See in Larchmont Homes
- Salt-air corrosion on Sound-facing exposures. Larchmont sits directly on Long Island Sound, so its predominately 1890s-1930s Victorian, Tudor Revival, and Colonial Revival chimneys endure salt-air corrosion on top of normal creosote buildup, a combination that erodes mortar joints and spalls brick far faster than in inland Westchester towns like Scarsdale or White Plains. Homeowners here are therefore far more likely to need both a cleaning and a masonry or liner repair on the same visit.
- Freeze-thaw cycle damage to mortar joints. Direct Long Island Sound exposure means nor’easters drive salt moisture into chimney masonry from the seaward side, while winter freeze-thaw cycles expand that moisture in already-weakened mortar joints, a coastal stress cycle noticeably worse here than even a few miles inland in Westchester. Chimney crowns and caps on Sound-facing exposures in Larchmont tend to fail on shorter cycles than the industry average.
- Legacy fuel-switch conversions with unlined flues. Technicians working Larchmont Manor regularly find chimneys where the original coal-era flue was later converted to an oil or gas appliance without a proper liner insert, a legacy of mid-20th-century fuel-switch retrofits that were common in these large Victorian homes, making oversized, unlined flues a near-standard discovery that requires documentation for both the homeowner and Westchester County code compliance.
- Multi-flue deterioration in original brick stacks. The village’s housing stock is overwhelmingly pre-WWII, with original multi-flue brick chimneys, particularly in the Larchmont Manor neighborhood, that were designed for coal or wood fires and are often unlined or have cracked, century-old terra cotta tile liners that no longer meet modern safety codes. A single chimney stack commonly serves two to three separate flues (furnace, one or two fireplaces), so a routine cleaning frequently reveals multiple distinct deterioration issues in one job.

FAQs - Chimney Liner & Rebuild in Larchmont
Yes. An unlined flue that “worked fine” for coal in 1925 is not safe for modern gas or oil combustion, and it does not meet current Westchester County code. The lower temperatures and different exhaust chemistry of modern appliances, combined with a century of mortar deterioration, create a fire and carbon monoxide hazard that wasn’t present with the original coal fire. We document this with Level-2 camera inspection photos you can see, and we explain the code requirement in plain English. Call (855) 950-3861 for a free estimate, estimates are free.
Salt-laden moisture from Long Island Sound nor’easters penetrates crown concrete at the microscopic level, then winter freeze-thaw cycles expand that moisture and crack the crown from within. This coastal stress cycle is measurably worse in Larchmont than even a few miles inland, and it accelerates once the crown’s protective seal is breached. We rebuild Larchmont crowns with proper slope, expansion joints, and waterproofing specifications that account for this exposure. Call (855) 950-3861 if you’re seeing crown cracks or water stains on your chimney brick.
No. A cracked terra cotta liner cannot be reliably patched or partially replaced. The material is brittle, the crack indicates systemic deterioration, and any repair would fail to contain heat and combustion gases as required by code. We remove the failed terra cotta and install a new stainless or flexible alloy liner sized to your appliance. The old material comes out, the new material goes in, and we camera-verify the full length. Call (855) 950-3861 to discuss your specific flue condition.
A two-flue liner replacement in Larchmont typically runs $4,800-$7,500, including removal of old material, flue preparation, new stainless steel liner installation with proper insulation and connectors, and final camera verification. The upper end applies when flues are oversized from coal-era construction or when access requires scaffolding. We provide exact pricing after inspection, not ballpark guesses. Call (855) 950-3861 for your free estimate.
No. A full teardown is rarely necessary for liner installation. We access the flue from the top and bottom, remove old material through the cleanout or thimble, and insert the new liner with specialized equipment. The exterior masonry stays intact unless it has deteriorated to the point of structural compromise, which we assess and document with photos before any masonry work is proposed. Most Larchmont liner jobs are completed in a single day without scaffolding beyond standard roof access. Call (855) 950-3861 to schedule your inspection and get a clear verdict on your chimney’s condition.
