Fast, Reliable Chimney Liner & Rebuild Across Larchmont
Chimney liner installation and chimney rebuilds in Larchmont typically run $2,800–$12,500 depending on whether we’re pulling a stainless liner through an existing flue or rebuilding a salt-damaged stack from the roofline up. Most liner jobs in the 10538 zip code are completed in one to two days, with partial and full rebuilds taking two to five days once materials are staged. Call (833) 719-7193 for a free, on-site estimate — we carry the full DuraFlex and HeatShield inventory needed for Larchmont’s older flue systems, so we’re not waiting on deliveries while your fireplace sits out of commission.
We’ve been working Larchmont chimneys long enough to know the pattern. You schedule what you think is a routine sweep. We show up to a 1920s Tudor on Rockland Avenue or a Victorian on Magnolia Drive, run the camera, and find clay-tile shards, sandy mortar, or no liner at all — just century-old brick exposed to decades of coal, oil, and gas exhaust. That’s not a cleaning anymore. That’s a liner or rebuild conversation, and Larchmont’s coastal position makes it more urgent than most Westchester homeowners realize.

Stainless Steel Liner Installation
A 316L stainless steel liner is the standard we install in most Larchmont homes with intact masonry but compromised or missing flue lining. These are rigid or flexible tubes that create a sealed, correctly sized combustion path inside your existing chimney. In Larchmont’s Manor-area streets, we regularly pull DuraFlex flexible liners through flues that were never properly lined when the home converted from coal to oil or gas — the original clay tile, where it exists, is often cracked from thermal cycling and salt intrusion. A stainless liner contains the exhaust, prevents creosote migration into porous brick, and brings the system up to modern NFPA 211 standards. Typical range in Larchmont: $2,800–$4,500 for a single-flue install, including the connector, top plate, and cap.
Flexible Liner Systems
Flexible liners are essential for Larchmont’s offset chimneys — the Victorian and Colonial-era stacks that jog around floor joists and wall framing on their way to the roof. A rigid liner won’t make those turns; a DuraFlex 316Ti or 316L flexible liner will. We size these carefully. Mismatched flue liners from successive fuel conversions are common in Larchmont, and an undersized flexible liner creates turbulence and condensation that can eat through thin-wall stainless within five years. We measure the appliance, the flue, and the offset before we spec the material. Flexible liner jobs in Larchmont generally fall between $3,200–$5,000 for standard residential fireplaces and boiler flues.
Liner Replacement
Sometimes there’s already a liner in place, but it’s failed — separated joints, corrosion holes, or improper sizing from a previous install. We see this frequently in Larchmont homes where a handyman or generalist dropped in a cheap aluminum liner rated for gas only, then the homeowner switched back to wood. We pull the old material, inspect the surrounding masonry for salt damage, and install a replacement sized to the actual appliance. If the crown or shoulder is compromised — common on Sound-facing homes where salt air has accelerated deterioration — we’ll address that before the new liner goes in. Larchmont liner replacements typically run $3,500–$6,000 depending on access and what we find above the roofline.
Partial Chimney Rebuild
A partial rebuild addresses the stack from the roofline up — the area most exposed to Larchmont’s coastal weather. We see this need constantly on waterfront homes along the Sound-facing streets, where salt-laden air dissolves mortar joints faster than the Westchester County average and hard freeze-thaw cycles open those joints into serious spalling. The crown separates from the flue tiles. The brick face shells off. A liner alone won’t fix structural failure. We dismantle to sound masonry, rebuild with matching brick where possible, and install a proper concrete crown with correct overhang and drip edge. Partial rebuilds in Larchmont range from $4,500–$8,500, with Sound-front properties often at the higher end due to accelerated damage.

Trusted Brands We Service in Larchmont
We don’t use hardware-store substitutes. For Larchmont’s harsh coastal environment, we specify DuraFlex 316L and 316Ti flexible liners, HeatShield cerfractory resurfacing for compromised flue surfaces that don’t warrant full liner replacement, and Famco and Copperfield caps and chase covers. These are the same product lines specified by chimney industry professionals for salt-air exposures. We stock common diameters and fittings locally, so when Anthony scopes your flue and identifies the need, we’re not ordering parts and making you wait two weeks. Most Larchmont liner jobs are staged and completed within a week of estimate approval.
Common Chimney Liner & Rebuild Problems We See in Larchmont Homes
- Salt-air accelerated mortar spalling on Sound-facing homes causes crown and flue-tile separation, turning what starts as a liner replacement into a partial rebuild once we get eyes on the stack. The mortar turns sandy and friable — you can scratch it with a fingernail — and the crown cracks let water straight into the flue system.
- Mismatched flue liners from successive fuel conversions — coal to oil to gas, sometimes with a wood fireplace still active — create turbulence and condensation that destroys improperly sized liners. We find 4-inch gas liners trying to handle wood-burning exhaust, or multiple appliances sharing a flue never designed for combined loading.
- Original single-wythe brickwork on Manor-area Victorians has no structural insulation and no air gap. A chimney fire or even repeated high-heat fireplace use can crack adjacent flue tiles already compromised by coastal humidity. These chimneys were built for coal — slow, cool burns — not modern fireplace temperatures.
- Clay-tile liner shards blocking the flue from decades of thermal expansion and salt intrusion. The tiles crack, shift, and sometimes collapse into the smoke chamber. We scope before we quote because the difference between “liner replacement” and “rebuild with new liner” is what’s left of the original structure.

FAQs — Chimney Liner & Rebuild in Larchmont
Not necessarily. We inspect each flue independently with a video camera. In Larchmont’s pre-WWII homes, it’s common to find one flue actively used for a fireplace, one serving a boiler or furnace, and one abandoned or capped. Only the active flues require liners sized to their appliances. The abandoned flue may need sealing to prevent water intrusion, especially given Larchmont’s coastal humidity. Call (833) 719-7193 and Anthony will scope all three — estimates are free.
Larchmont’s position on a small peninsula directly on Long Island Sound means persistent coastal humidity and salt-laden air that dissolves mortar joints faster than the Westchester County average. White Plains sits 5 miles inland — enough distance that salt corrosion is minimal. In Larchmont, that salt air attacks the crown, the flashing, and the exterior mortar, which then lets water into the flue system and accelerates liner failure from the outside in. We see this pattern constantly on Sound-facing streets in the Manor and Pine Brook areas.
Single-wythe means one layer of brick — no air gap, no structural backup wall. These chimneys, common in Larchmont’s 1900s–1920s housing stock, rely entirely on that single brick layer for structural integrity. When salt air and freeze-thaw cycles compromise the mortar, the whole stack becomes unstable. A liner won’t fix structural failure. If the wythe is intact, we line it. If the brick is spalling, shifting, or separating from the flue tiles, you’re looking at partial or full rebuild pricing — typically $4,500–$8,500 for partial, $8,500+ for full — before the liner goes in.
Yes, if the chimney has separate flues — which most Larchmont homes of this era do. Each appliance needs its own correctly sized liner; sharing a flue between gas and wood is a code violation and a safety hazard. We size the wood-burning liner to NFPA 211 standards (typically DuraFlex 316L) and the gas liner to the appliance manufacturer’s spec. The challenge in Larchmont’s older chimneys is often flue size — successive fuel conversions may have left flues too small or too damaged for proper liner installation. That’s where our inspection determines whether relining is viable or rebuild is necessary.
Hairline cracks can sometimes be addressed with HeatShield CrownSeal or similar cerfractory resurfacing if the crown is structurally sound and the cracks haven’t allowed water into the flue system. In Larchmont, we evaluate this carefully because salt-air corrosion often means the cracks are deeper than they appear, and the underlying mortar is compromised. If the crown is separating from the flue tiles or the brick below is spalling, patching is a temporary fix at best — you’re looking at crown replacement as part of a partial rebuild. Anthony will give you a straight assessment after inspection; call (833) 719-7193 to schedule.
