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 Mamaroneck
A stainless steel liner replacement in Mamaroneck typically runs $2,800 to $5,400, and a full chimney rebuild usually lands between $7,500 and $14,000 depending on stack height and brick access. We know those numbers matter, which is why we quote them before a single tool comes off the truck. Wendell Pike started Top Hat Chimney in 1999, and he’s been inside enough Mamaroneck chimneys to know that the salt air off Long Island Sound doesn’t just wear on siding and windows. It eats at mortar and brick from the outside while old clay tile flues quietly fail from the inside. Call (914) 685-6096 and you’ll get a straight answer, not a script.
Why Top Hat Chimney Is Mamaroneck’s Preferred Chimney Liner & Rebuild Company
We’re not new here. We’re not a franchise that rotated in last spring with a leased van and a call center in another state. Wendell has been running Chimney Liner & Rebuild jobs in Westchester for over 29 years, and Mamaroneck homeowners tend to know someone who knows someone. Ask anyone on your street. The homes along Orienta Avenue, down by Harbor Island Park, and up in the villages near Mamaroneck Avenue School are the same chimneys we’ve been working on for decades. They don’t get easier with age, and neither do the problems hiding inside them.
Every job we finish in Mamaroneck gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. That’s not a slogan. It’s stamped on the invoice. And the phone number on that invoice is answered by a live person, around the clock. It may well be Wendell himself picking up at 2 a.m. because someone’s carbon monoxide detector went off and they’re not sure what to do. That’s the difference between a local owner-operator and a national outfit that routes you through a menu.
Our Chimney Liner & Rebuild Services in Mamaroneck
Stainless Steel Liner
A stainless steel liner is the workhorse fix for most Mamaroneck homes built before World War II. We install liners from DuraFlex and Copperfield, and we match the alloy to what your appliance actually needs. If you have a boiler or water heater venting into an old masonry chimney, that flue gas is cooler and wetter than fireplace smoke. It condenses inside the old clay tile, eats through the mortar joints, and starts leaking carbon monoxide into the house. A stainless liner is not an upsell here. It’s the difference between a chimney that breathes and one that leaks.
Flexible Liner
Flexible liners make sense when the existing flue isn’t perfectly straight, which is the case in a lot of Mamaroneck’s Tudor Revivals and brick colonials. Those pre-war stacks twist and shift over decades, and a rigid liner simply won’t follow the path without opening up the masonry. We pull the old tile, snake the flexible liner through, and seal it properly. What we don’t do is sell you a flexible liner because it’s faster for us. If a rigid liner fits and serves the appliance better, that’s what we recommend.
Liner Replacement
Most of the original clay tile liners in Mamaroneck’s 1910s and 1920s housing stock are 70 to 100 years old. They were never designed to last this long. The freeze-thaw cycle along the Sound keeps the masonry wet, and the coastal humidity accelerates the breakdown of the mortar joints between tile sections. The result is offset, cracked, or missing tiles that you can’t see from the ground. We use a camera to show you exactly what’s failing before we recommend anything. Then we replace the liner, not the whole chimney, if the brick is still sound.
Partial Rebuild
A partial rebuild addresses what’s actually damaged, not what a commission-based salesperson wants to sell you. In Mamaroneck, that often means the top eight to fifteen courses of brick below the crown, where salt-laden rain has soaked in year after year. We rebuild that section, repoint the joints with mortar matched to your home’s era, and pour a proper crown that sheds water instead of holding it. We also repair the south- and southwest-facing faces first, because that’s where the Sound does its worst work.

Common Chimney Liner & Rebuild Problems We See in Mamaroneck Homes
- Salt-driven south-face spalling. The onshore winds off Long Island Sound carry salt crystals into the brick on south- and southwest-facing chimney faces, especially down by the harbor and Orienta neighborhoods. Those faces crumble years before the rest of the stack, and we check them first on every Mamaroneck job.
- Original clay tile liners past their service life. Homes built between 1910 and 1940 almost always still have their original clay tile flues. They crack, offset, and spall from the inside, and they don’t announce themselves until an inspection finds them, or a carbon monoxide detector doesn’t.
- Flood-related moisture from the Mamaroneck River. Lower-lying areas near the river and harbor can get water into ash pit cleanouts during the flood events this village knows too well. That bottom-up moisture corrodes liners and softens masonry in ways a standard top-down inspection never sees.
- Converted coal and oil furnace stacks. Many Mamaroneck chimneys originally served a coal furnace or an oil burner, then got converted to gas. The flue size and condition don’t match the new appliance’s venting needs, which creates condensation, draft problems, and hidden carbon monoxide risk inside wall cavities.
Pricing for Chimney Liner & Rebuild in Mamaroneck, NY
Here’s honest money. A stainless steel liner replacement in Mamaroneck runs $2,800 to $5,400, depending on flue height and whether scaffolding is needed. A partial rebuild like the one we did in Orienta, where the top section of the stack needed repointing and a new crown, runs $3,500 to $6,500. A full chimney rebuild starts around $7,500 and can reach $14,000 on taller stacks with complicated roof access. Nothing is recommended without camera footage you can see with your own eyes. That’s the thing. If a chimney company tells you the liner is shot and you need to write a check, ask to see the video.

FAQs - Chimney Liner & Rebuild in Mamaroneck
You usually can’t tell from the ground, which is why we camera every liner before recommending anything. What you can spot from outside is early salt damage to the brick itself. Walk around to the south and southwest sides of your chimney. If the mortar joints look recessed, or the brick faces are flaking, peeling, or missing entirely, the salt air has been doing its work for years. That same moisture pathway eventually reaches the liner and the flue. If you’re near the harbor or Orienta, those faces fail first. Call (914) 685-6096 and we’ll put a camera up there before you spend a dollar on repairs.
Not necessarily. If the south-facing brick face is crumbling but the rest of the stack is sound, a partial rebuild often solves it. We remove the damaged brick, reline if needed, repoint the surrounding joints, and pour a new crown. The homeowner on Orienta Avenue whose chimney we rebuilt had one entire face spalled so badly the clay tile flue was visible through the gaps. We installed a new DuraFlex liner and rebuilt the upper stack, but we didn’t tear down the whole chimney. It didn’t need it, and you shouldn’t pay for a full rebuild when a partial one does the job. The camera footage tells us which one applies.
Because the salt air and coastal humidity here attack masonry faster than the dry, inland conditions in towns like White Plains or Tarrytown. The onshore winds off Long Island Sound drive salt crystals into aging mortar year-round, and the village’s pre-WWII housing stock means most of those chimneys are already past their original design life. An annual inspection here isn’t a formality. It’s how you catch a $600 repointing job before it becomes a $9,000 rebuild. Once a year, burn or no burn. Chimneys break in the off-season too.
Yes. Homes in the lower-lying central and harbor areas can have water intrude through ash pit cleanouts during flood events. That water sits in the base of the chimney, wicks into the masonry, and corrodes the liner from the bottom up. A standard top-down inspection with a flashlight won’t see it. We check the cleanouts and the ash dump area on every Mamaroneck job, because we know which pockets of this village flood and which ones don’t. If you’ve had water in your basement near the chimney, tell us. It changes where we look.
Cracked and offset clay tile sections caused by decades of coastal moisture plus the original furnace conversion. Most of these chimneys were built for a coal or oil fire burning hot and dry. Then the furnace got swapped for gas, which vents cooler and wetter. The old clay tiles soaked up that moisture, the mortar joints between them eroded, and the tiles shifted. We see it in brick colonials, Tudor Revivals, and pre-war frame houses throughout the village. The fix is a proper stainless liner sized for the current appliance, not a patch job. Call (914) 685-6096 for a free estimate. We’ll show you the footage and explain it in plain English, every time.
