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 Liner & Rebuild Across Larchmont
If you own a home in Larchmont, especially one of the older ones near the Sound, your chimney is fighting a battle most inland chimneys never face. Salt-laden air from Long Island Sound works its way into mortar joints year-round. Then winter freeze-thaw cycles crack what the salt has softened. The result is a chimney that looks fine from the street but has hidden damage inside the flue. Our Chimney Liner & Rebuild team handles these coastal-specific failures every week, from Beach Avenue to the streets around Flint Park. Call (914) 685-6096 if you suspect your liner has had enough.
Why Top Hat Chimney Is Larchmont’s Preferred Chimney Liner & Rebuild Company
We have worked on more Larchmont chimneys than we can count. Ask anyone on your street. Wendell Pike started Top Hat Chimney back in 1999, and he still puts his name on every job, publishes his license number, and backs the work with a 90-Day Done Right Promise in writing. If something is not right, one call brings him back. That matters when you are deciding whether to trust someone with a several-thousand-dollar liner installation. Homeowners in Larchmont Manor and the surrounding historic streets have seen too many national outfits quote one price on the phone and a different one at the door. We do not work that way. The number you hear is the number on the invoice, delivered before a single tool comes off the truck. Our customers in Larchmont also get a real arrival window and a call if the schedule shifts. A live person picks up the phone around the clock, and it is often Wendell himself.
Our Chimney Liner & Rebuild Services in Larchmont
Stainless Steel Liner
A stainless liner is the long-term fix for a flue that has cracked, spalled, or was never lined at all. In Larchmont, where salt air accelerates deterioration on interior flue surfaces too, stainless holds up far better than clay tile or an unlined masonry stack. We install DuraFlex stainless systems sized to your specific flue and appliance. The material resists the corrosive condensate that gas appliances produce, which is a problem we see often in older Larchmont homes that converted from oil to gas decades ago.
Flexible Liner
Chimneys built between 1890 and 1940 rarely run in a perfectly straight line. That is where a flexible liner earns its keep. It follows the existing offset and slip sections without requiring major demolition, which matters when you are preserving the exterior brickwork on a 1910 Tudor in Larchmont Manor. We use Copperfield and DuraFlex flexible systems depending on the flue dimensions and what the camera inspection reveals. The liner gets insulated where the run is tight or the flue is exterior-facing toward the Sound.
Liner Replacement
If your clay tile liner is cracked from years of freeze-thaw with ocean moisture, replacement is not optional. We routinely find Larchmont chimneys where the original tile liner from the 1920s or 1930s has multiple vertical and horizontal fractures. You cannot see these from the rooftop without a camera. We will not recommend replacement until we show you the footage. Plain English, every time, no exceptions. Then we size the correct stainless liner, remove what is left of the old tile, and have the flue ventilating properly again.
Partial Rebuild
A partial rebuild addresses the top section of the chimney, typically the crown and the upper courses where salt-driven spalling does the most damage. We rebuilt the top 12 courses of a 1910 Tudor chimney on Beach Avenue after the brick face had blown off and left the flue exposed. While we had it open, we found the original clay liner cracked in three separate places. The fix was a DuraFlex stainless liner and a rebuilt crown with a proper wash to shed water toward the cap, not back into the masonry. That is the level of inspection we bring to every partial rebuild, no exceptions.

Trusted Brands We Service in Larchmont
We install and service liners and rebuild components from Famco, Copperfield, and DuraFlex, so if your existing system uses one of those brands, we can match and repair it properly. Because we work Larchmont chimneys constantly, we keep common liner diameters, connectors, and crowns on hand, which speeds up the work when a chimney fails in March after a hard winter. You will not wait weeks for a part to ship across the country. If your liner is still under manufacturer warranty, we handle the paperwork and install the replacement correctly the first time.
Common Chimney Liner & Rebuild Problems We See in Larchmont Homes
- Unlined flues venting converted gas appliances. Many Larchmont homes switched from oil to gas in the 1980s and 1990s, but the heating contractor rerouted the flue and left the original unlined masonry in place. That is a code violation in Larchmont and a hidden carbon monoxide risk.
- Salt-corroded steel dampers and flashing on the Sound-facing side. Homes closer to the water, especially in Larchmont Manor, get more salt air against the chimney’s windward face. The damper seizes, the flashing rots, and water saturates the smoke chamber. A Level 2 camera inspection is the only way to see the full extent.
- A beautifully repointed crown hiding a failing flue. We see this constantly: homeowners invest in brick repointing, the chimney looks perfect from the street, and nobody checks the liner. The flue interior is still cracking from years of coastal moisture. Now the stack looks great and vents badly.
- Freeze-thaw spalling on upper courses. Salt air works into mortar joints. Winter freezes the moisture. Spring thaws it. The cycle widens joints, pops brick faces, and exposes the flue liner behind it. Larchmont’s location directly on the Sound makes this worse than inland Westchester towns just a few miles north.
Pricing for Chimney Liner & Rebuild in Larchmont, NY
Here are honest numbers for what we charge in Larchmont. A stainless steel liner installation runs roughly $2,800 to $5,200 depending on flue height, diameter, and whether we are doing a straight run or a flexible offset. Liner replacement on a two-story Larchmont chimney typically lands between $3,200 and $6,000, again depending on access and the condition of the remaining masonry. A partial rebuild of the top 8 to 12 courses runs $3,500 to $7,800, which includes new flashing, a proper crown wash, and any liner section that needs attention. A full rebuild from the roofline up starts around $8,000 and goes up from there. We include camera inspection and a photo report before any liner or rebuild recommendation, so you can see exactly what you are paying for. No trip charge inside the county, and we offer a free second opinion on any competing written estimate. Call (914) 685-6096 for an exact quote.

FAQs - Chimney Liner & Rebuild in Larchmont
Salt air makes a liner in Larchmont more critical than in inland towns, because it accelerates the deterioration of both the exterior mortar and the interior flue surfaces. Moisture carrying salt penetrates the masonry, and when it condenses inside the flue, it attacks the clay tile or unlined brick from within. Combine that with the village’s dense stock of 1890s to 1930s chimneys, many without proper liners, and you have a higher rate of hidden flue failure here than in places like Harrison or Eastchester. A stainless liner is the only long-term defense. Call (914) 685-6096 and we will show you what your flue actually looks like.
Because repointing fixes the joints but does not address the structural loss that salt air has already caused to the brick itself. In older Larchmont Manor homes, spalling often removes entire brick faces from the upper courses, which changes the load path and lets water behind the remaining masonry. Repointing over missing brick faces is like painting over rotten wood. A partial rebuild replaces the compromised courses, corrects the crown wash, and gives the chimney a fighting chance against another 40 years of Sound air. We will never recommend a rebuild without camera footage you can see yourself.
Almost certainly yes, and it is a code issue in Larchmont, not just a preference. Gas appliance flues produce acidic condensate that eats through old clay tile and unlined masonry. The original oil-era flue was not sized or rated for gas, and running a gas appliance through an unlined stack is a direct violation of current NFPA and local code. We see this exact scenario repeatedly in Larchmont, where oil-to-gas conversions happened in waves decades ago and the liners were never touched. A stainless liner sized for your specific gas appliance solves it. Get an estimate from us at (914) 685-6096 before the next heating season.
Water staining on the ceiling near the chimney, or efflorescence, which is the white powdery mineral deposit on the brick face. Those mean water is getting past the crown and into the masonry. In Larchmont, we also look for rust-colored staining from the damper area. If the crown has a flat wash instead of a sloped one, or if the concrete is cracked through to the flue, a patch buys you maybe one winter. A rebuild with a proper sloped wash and a drip edge gives you 15 to 20 years. Call us and we will tell you which one applies to your crown.
That depends entirely on what the camera shows, not on how often you burn. Many Larchmont homeowners use their fireplaces once a year on Thanksgiving, and they still have cracked clay tile liners from coastal moisture, freeze-thaw stress, and decades of neglect. The liner protects the house whether you burn once a year or every weekend. If the liner is compromised, even occasional use is a fire and carbon monoxide risk. If you have not had a camera inspection, you do not actually know what condition the flue is in. Call (914) 685-6096 and we will bring the camera and show you the truth, plain and simple.
