Fast, Reliable Chimney Cap & Crown Across Larchmont
Chimney cap and crown repair in Larchmont typically runs $340-$890 depending on whether we’re sealing surface cracks or rebuilding a full crown, and most jobs are completed in a single visit with our crew arriving from our New York City base within 45 minutes to an hour. If you’re seeing water stains on your ceiling near the chimney breast, or if pieces of concrete are falling from the top of your stack, the crown has likely failed and needs attention before the next nor’easter.
We’ve been working on Larchmont chimneys since 1984. Our Chimney Cap & Crown team knows the village’s housing stock intimately: the Victorian piles in Larchmont Manor, the Tudor Revivals along Palmer Avenue, the Colonials nearer to the Boston Post Road corridor in the 10538 zip. These aren’t generic suburban chimneys. They’re original multi-flue brick stacks, often unlined or lined with cracked century-old terra cotta, and they’ve been taking salt spray off Long Island Sound for generations. That coastal exposure changes everything about how caps and crowns fail, and how we fix them.

Our 90-Day Done Right Promise is in writing with no arguing. If it’s not right, we come back. That’s been our standard for over 42 years.
Larchmont homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years. They’ve also been burned by contractors who disappeared or talked in circles about pricing.

Response time to Larchmont is consistently under an hour from our New York City operation. We carry professional-grade materials from Famco, Copperfield, and DuraFlex on our trucks, so most repairs are completed in a single visit without waiting for parts. And because we understand the local conditions - the salt-air corrosion, the freeze-thaw cycles, the legacy fuel-switch retrofits common in these pre-WWII homes - we don’t waste your time with solutions designed for inland construction.
Our Chimney Cap & Crown Services in Larchmont
Crown Repair
Crown repair is our most common call in Larchmont, and for good reason. The concrete crown is the chimney’s umbrella, sloped to shed water away from the flue. On Sound-facing exposures, especially in Larchmont Manor and along the Palmer Avenue corridor, salt-laden nor’easter winds drive moisture into micro-cracks that expand with every freeze-thaw cycle. We’ve seen crowns spall and delaminate within three to five years of installation, half the inland lifespan.
Our crown repair process starts with a Level-2 camera inspection. We photograph the damage, check the flue liner beneath, and give you a verdict: surface sealing with CrownCoat or FlexSeal for minor cracking, or full cast-in-place concrete replacement when the crown has separated from the brick stack. For a typical Larchmont crown repair, expect $420-$680. Full replacement runs $740-$890.
Multi-Flue Cap Installation
Original Larchmont chimneys were built for coal. A single stack commonly serves two or three flues: furnace, living room fireplace, maybe a second-floor hearth. Each flue needs its own cap, or better, a single multi-flue cap that covers the entire crown and sheds water past the brick edges. The alternative - individual flue caps with gaps between - lets water pool on the crown surface and accelerate deterioration.
We install multi-flue caps from Copperfield and Gelco, sized to your chimney’s exact dimensions. Most Larchmont installations run $380-$560 for stainless steel, $620-$940 for custom copper. The copper develops a patina that complements the village’s historic architecture, particularly on the Tudor and Colonial Revival homes where the original detailing matters to the homeowner.
Custom Cap Fabrication
Some Larchmont chimneys defy standard sizing. Oversized flues from coal-era construction. Offset pots added during mid-century conversions. Decorative brickwork that can’t be drilled for conventional mounting. For these, we fabricate custom caps in galvanized steel, stainless, or copper, with welded seams and proper slope and overhang.
Custom caps start around $680 in Larchmont and can reach $1,400 for large multi-flue copper assemblies with integrated spark arrestors. We measure twice, fabricate to order, and install with stainless steel hardware that won’t rust out in the salt air.
Cap Replacement
The original cap on your Larchmont chimney may be decades old. Galvanized steel rusts through. Mesh screens clog with creosote or corrode. Hinges seize. We’ve replaced caps on 1950s-era installations where the spring hinges had disintegrated entirely, leaving the flue open to rain and raccoons.
Cap replacement is straightforward if the crown beneath is sound: $280-$440 for standard stainless steel, $340-$520 with animal-proof mesh and lifetime warranty. But we always inspect the crown first. A new cap on a failing crown is money wasted, and we’ll tell you so directly.

Trusted Brands We Service in Larchmont
We stock professional-grade materials from Famco, Copperfield, and DuraFlex on every truck serving Larchmont. No builder-grade substitutes. Famco’s stainless caps hold up to salt-air corrosion better than galvanized alternatives. Copperfield’s multi-flue assemblies are the standard we specify for Larchmont Manor’s landmark-quality homes. DuraFlex liner systems integrate with our crown and cap work when we discover unlined or damaged flues during the same visit. Because we carry inventory, most Larchmont jobs don’t wait for parts. The cap or crown goes on the same day we diagnose it.
Common Chimney Cap & Crown Problems We See in Larchmont Homes
- Salt-air spalling on Sound-facing crowns. Nor’easters drive salt moisture into crown concrete from the seaward side. Freeze-thaw expansion pops the surface off in layers. We see this most often on homes in Larchmont Manor and along the Locust Avenue corridor, where the chimneys face directly toward the Sound.
- Missing or undersized caps on coal-era multi-flue chimneys. Original construction often lacked caps entirely, or used small single-flue covers inadequate for later conversions. Birds nest. Debris accumulates. Flues that haven’t been cleaned since the gas conversion in 1962 are suddenly blocked.
- Crown separation from freeze-thaw in unlined flues. When combustion gases cool too quickly in an oversized, unlined flue, condensation saturates the masonry. Winter freeze-thaw expands that moisture, pushing the crown away from the brick stack. The leak shows up as a water stain on your bedroom ceiling, three feet from where you’d expect it.
- Legacy fuel-switch damage. Mid-20th-century conversions from coal to oil or gas often left oversized flues without proper liner inserts. The resulting turbulence and condensation accelerate crown deterioration from the inside out. We document these findings for Westchester County code compliance, with photos and a written verdict.

FAQs - Chimney Cap & Crown in Larchmont
Salt spray from Long Island Sound accelerates concrete spalling by infiltrating micro-cracks and expanding during freeze-thaw cycles, a stress cycle noticeably worse in Larchmont than even a few miles inland in Westchester. Crown failure on Sound-facing exposures typically occurs in three to five years versus seven to ten inland. We specify denser concrete mixes and premium sealants for Larchmont installations to extend service life. Call (855) 950-3861 and we’ll assess your exposure and recommend the right protection.
Yes. Multi-flue caps are our standard recommendation for Larchmont Manor’s original coal-era chimneys, which commonly serve two or three flues from a single stack. We measure the full crown dimension and install a sloped, overhanging cap from Copperfield or Gelco that sheds water past the brick edges, protecting the crown beneath. Most three-flue installations in Larchmont Manor run $480-$720 in stainless steel, $780-$1,100 in custom copper. We’ll photograph your flue condition and document any unlined coal-era construction for Westchester County compliance during the same visit.
We repair when the concrete is sound beneath the surface spalling, and replace when the crown has delaminated or separated from the brick stack. On a 1927 Tudor Revival on Locust Avenue in Larchmont Manor, our crew found the concrete crown had delaminated from years of salt-air intrusion, allowing water to rot the terra cotta flue liner beneath. We replaced the crown with a cast-in-place concrete crown and installed a custom copper multi-flue cap from Copperfield to seal all three flues, then documented the unlined coal-era flues for Westchester County code compliance. Surface repairs run $340-$520; full replacement is $740-$890. We’ll show you photos and give you an honest verdict.
Yes, if the crown beneath is intact. Rusted hinges and corroded mesh are common on mid-century galvanized caps in Larchmont, and replacement with stainless steel solves the problem permanently. We always inspect the crown first, because a new cap on a failing crown leaks anyway. Standard stainless replacement with animal-proof mesh runs $280-$440. If the crown needs attention, we’ll tell you before we proceed, with photos. Estimates are free - call (855) 950-3861.
A new stainless steel chimney cap on a typical Larchmont colonial runs $280-$440 for a single flue, $380-$560 for a multi-flue assembly. Custom copper caps for historic homes start around $620 and can reach $940 depending on size and detailing. The colonial chimneys near the Boston Post Road corridor in 10538 often have simpler single-flue construction than the multi-flue stacks in Larchmont Manor, which keeps costs toward the lower end. We’ll measure your flue, check your crown, and give you an exact quote before any work begins. Call (855) 950-3861 for a free estimate.
