Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Larchmont
Chimney repair in Larchmont usually involves one of three things: corroded metal components from salt air, crumbling mortar and brick from freeze-thaw cycles, or a flue liner that no longer meets code after an oil-to-gas conversion. Most repairs run between $400 and $2,800 depending on what failed first, and we get there fast - Larchmont is a short drive for our crew. Call (914) 685-6096 and you’ll speak with a live person who can tell you what to expect before anyone arrives.
We know Larchmont chimneys. Not from a spreadsheet, but from decades of ladders up against Tudor, Colonial Revival, and Craftsman exteriors between Larchmont Manor and the village streets near the train station. Your chimney gets hit harder here than it would in Mamaroneck or inland Westchester, and the repairs that matter most in Larchmont are not always the ones a national chain checks first.

Our Chimney Repair Services in Larchmont
Flashing Repair
Flashing is where coastal chimneys fail first, and Larchmont sees more of it than inland towns because salt-laden moisture attacks the metal at the roofline. We remove rusted galvanized pieces, inspect the joint beneath, and install stainless flashing that holds up far longer against marine air. On a 1920s Tudor near Larchmont Manor, we recently found flashing so corroded it had opened a channel for water into the attic while the shingles around it still looked fine.
Chimney Waterproofing
Waterproofing is not paint. It’s a vapor-permeable barrier that lets moisture out while stopping rain and salt spray from soaking into masonry. In Larchmont, where the Sound’s humidity works into mortars year-round, we recommend waterproofing after any repointing or rebuild. It extends the life of the work meaningfully and costs far less than repairing spalled brick five years down the road.
Spalling Brick Repair
Spalling is the word for brick faces popping off as trapped moisture expands and contracts. We see it constantly on the 1890s-1930s masonry chimneys around Larchmont. The salt exposure from the Sound accelerates it beyond what age alone would explain. We cut out the damaged units, match the brick as closely as the supply allows, and repoint with mortar that accommodates the original structure. In the Manor district, matching the warm orange-brown clay is a craft in itself, and we take the time to do it right.
Mortar Repointing & Crown Repair
Your crown is the concrete cap that sheds water off the top of the chimney. On coastal homes, crowns crack early and grow moss from constant moisture. We rebuild them with slope, overhang, and drip edges that actually move water away. On a 1920s chimney in Larchmont, a properly built crown can add many years before any brick repair becomes necessary. Our Chimney Repair team includes masons who do this work daily, not subcontractors who arrive once a season.

Trusted Brands We Service in Larchmont
We install and service parts from DuraFlex, Famco, Copperfield, HeatShield, and others. In Larchmont, where salt air eats galvanized components, we recommend stainless steel for caps and flashings - DuraFlex stainless liners and Famco stainless caps are the ones we lean on. We carry a range of parts pre-stocked for jobs in Larchmont so most repairs happen in one visit. If your existing setup is a galvanized cap that’s rusting through after a few seasons by the Sound, swapping it for a Copperfield or Famco stainless cap is a common fix we handle without a follow-up appointment.
Common Chimney Repair Problems We See in Larchmont Homes
- Salt-corroded flashing at the roofline. Long Island Sound’s marine air eats galvanized metal fast. The flashing around your chimney is the first barrier and the first to go - by the time you see rust streaks inside the attic, the metal is already failing.
- Crumbling crowns and spalled bricks from coastal humidity. Freeze-thaw cycles force salt into mortar joints each winter. The result is cracked crowns, popped brick faces, and accelerated deterioration on chimneys built between 1890 and 1940 - which describes most of Larchmont Manor.
- Original clay tile liners cracked after oil-to-gas conversions. Many older Larchmont homes converted from oil heat decades ago, and the flue was rerouted but never properly relined. The original clay tiles, already stressed by salt and heat years, crack and create code-compliance and carbon monoxide risks inside the chase.
- Rusted dampers and chase covers. Salt air corrodes steel components inside and outside the flue. A rusted damper may still open by hand, but if the plate is pitted through, it stops sealing properly and exhaust backs into the house when the fire is lit.
Pricing for Chimney Repair in Larchmont, NY

| Flashing Repair (stainless) | $450 - $900 |
| Chimney Crown Rebuild | $800 - $1,800 |

| Chimney Waterproofing | $350 - $750 |
| Stainless Flue Liner (installed) | $1,800 - $3,500 |

A full reline with DuraFlex stainless and a new crown lands higher because we’re rebuilding what the coastal air has worn away over decades.

FAQs - Chimney Repair in Larchmont
Your chimney needs an annual salt-damage inspection, not just a standard cleaning. The Sound’s marine air deposits salt into porous brick and mortar, which then expands during winter freeze-thaw cycles and accelerates spalling. Metal components - flashing, caps, dampers - corrode far faster than inland. In Larchmont, we check the cap, flashing, and crown for rust and salt damage at least once a year, and we recommend stainless steel replacements rather than galvanized wherever replacement is needed. Call (914) 685-6096 to schedule before burning season.
Because the original unlined masonry or clay tile flue was almost certainly never properly assessed or relined when the heating contractor rerouted the gas exhaust. Gas combustion produces moisture that mixes with salt-laden coastal air inside the flue, cracking the old tiles and creating a hidden carbon monoxide risk. A DuraFlex stainless liner solves it cleanly, and in Larchmont we pair the liner with a stainless cap so the salt air doesn’t just move on to the next component. Call (914) 685-6096 for a camera inspection and a straight answer.
Flashing fails first, because it’s the thinnest metal and sits right where rain and salt spray hit hardest. Then the cap, because it’s constantly exposed. The crown goes after that, but only if the flashing and cap haven’t already let water into the masonry, which accelerates crown cracking and spalling. In Larchmont, we replace flashings and caps with stainless steel before the crown fails, because once the crown is gone, water gets into the stack itself and repair costs climb fast. One call to (914) 685-6096 gets you an inspection that tells you what’s actually urgent.
We recommend waterproofing after any major masonry repair and then re-applying every five to seven years, depending on your location’s exposure. Coastal chimneys in Larchmont need it more often than inland homes because salt spray accelerates the breakdown of the waterproofing layer itself. If water is already beading off the brick, you’re in good shape; if it soaks in, it’s time to reapply. Call (914) 685-6096 and we’ll tell you honestly whether your chimney needs waterproofing this year or not.
In most cases, yes. If the structural core is sound and the damage is in defined sections, we cut out the spalled faces, match the brick, and repoint the surrounding joints. For Larchmont Manor chimneys where the entire structure is salt-corroded and leaning, a partial rebuild is sometimes necessary, but we show you camera footage of every recommendation before you approve any work. Nothing is sold without evidence you can see. Call (914) 685-6096 for a free assessment.
