Key takeaways:

• Westchester’s 1920s-1950s housing stock means original clay tile flues are now 70-100 years old and failing from the inside.
• In historically designated villages like Bronxville and parts of Tarrytown, a visible rebuild or cap change can require a Certificate of Appropriateness before work starts.
• Every job includes camera footage of your flue before we recommend anything. You see what we see.
• Upfront pricing, a 90-Day Done Right Promise in writing, and a live person on the phone around the clock.

Why Top Hat Chimney Is Westchester County’s Preferred Chimney Liner & Rebuild Company

Top Hat Chimney is not a franchise that rotated into Westchester County last spring. Wendell Pike founded the company in 1999, and for over 29 years he has worked the same communities: Scarsdale, Bronxville, Pelham, Larchmont, White Plains, and the river towns. You’ll run into him again on Saturday at the hardware store, and that matters when someone has just told you your chimney needs six thousand dollars of work.

Westchester County Fireplace Services customers call us because the person who answers is a live person, around the clock. Not a call center. Often it’s Wendell himself. We give you a real arrival window, a background-checked crew in uniform, and the price you hear on the phone is the price on the invoice. No number changes at the door. That’s a specific promise, and we keep it in writing on every job: the 90-Day Done Right Promise. If it’s not right, one call brings the crew back.

Ask anyone on your street. We’ve been inside more chimneys in Westchester County than we can count, and we publish our name and license number. We don’t hide behind a corporation.

Our Chimney Liner & Rebuild Services in Westchester County

Stainless Steel Liner

A stainless steel liner is the workhorse fix for the oil-to-gas conversion problem we see constantly in Westchester County. When a 1940s Colonial in Mount Vernon switched from oil to gas decades ago, the furnace was often left venting into an oversized clay tile flue sized for a coal boiler. The result: acidic condensate eats the mortar bed from the inside. We install DuraFlex stainless steel liners sized correctly for today’s appliances, and we show you the camera footage before and after.

Flexible Liner

In Westchester’s older homes, chimneys are rarely straight. A 1920s Arts & Crafts bungalow in Tarrytown might have a flue that jogs twice before it reaches the crown. A flexible liner follows that path without opening the masonry. We use it where the original clay flue is intact enough to act as a chase but cracked enough to leak. The flexible liner goes in, the clay stays put, and the flue is sealed from top to bottom.

Liner Replacement

When the original clay tile liner in a 1930s Tudor has horizontal cracks at the roofline, repair isn’t the answer. Replacement is. In Westchester County’s freeze-thaw climate, water gets into those cracks, freezes, expands, and widens them year after year. We remove the old clay sections where accessible and line the flue with a correctly sized stainless steel system. The camera inspection confirms every joint. No guesswork, no overselling.

Partial Rebuild

Most chimneys in Westchester County don’t need a full rebuild. They need the top four to ten courses above the roofline replaced, where the weather hits hardest. A 1950s split-level in Harrison might have a crumbling crown and spalled brick at our Chimney Cap & Crown in Westchester County, while everything below the roofline is sound. A partial rebuild replaces the damaged masonry, repoints what’s loose, and puts a proper crown on top. If it doesn’t need a full rebuild, Wendell will say so plainly. That’s the whole point.

Trusted Brands We Service in Westchester County

We install and service chimney liners and rebuild components from HeatShield, Gelco service in Westchester County, and Olympia Chimney, and we keep common parts on the truck for local jobs. That means fewer trips back to the shop and less waiting around for a liner kit to ship. When a liner replacement in New Rochelle turns up an unexpected crown problem, we’re usually equipped to handle it the same visit. You get camera footage and a plain-English verdict every time, no exceptions.

Common Chimney Liner & Rebuild Problems We See in Westchester County Homes

• Shared stacks with failing adjacent flues: In attached homes through villages like Pelham and Larchmont, a neighbor’s oil-to-gas conversion can leave an oversized, unlined flue venting into the same masonry mass. Acidic condensate eats the mortar bed and cracks the flue next door. If your fireplace suddenly smells like exhaust, this is often why.
• Cross-contamination through party walls: A failed adjacent flue in a dense village rowhouse lets smoke and carbon monoxide migrate into the neighbor’s firebox. Our crew’s roof access from a narrow side alley makes this a two-ladder job, and we check both flues when we’re up there.
• Hudson River moisture damage: The Tarrytown-Yonkers corridor holds persistent dampness thanks to the river. Spalling accelerates on exposed crowns, the clay tile top joint opens up, water runs down the flue, and creosote turns to corrosive sludge. The liner fails from the inside out.
• Architectural review stalls: In historically designated villages like Bronxville and parts of Tarrytown, a visible cap change or rebuild above the roofline can require a Certificate of Appropriateness from the landmarks board. We flag this at the estimate stage so the job doesn’t stall for weeks halfway through.

One Thing About Westchester County Most Chimney Sites Never Mention

In Westchester’s historically designated villages like Bronxville and parts of Tarrytown, a visible chimney rebuild or cap change can trigger a Certificate of Appropriateness from the local architectural review board. That’s a permitting step almost never required in neighboring Rockland or Putnam counties, and one that can stall a liner job by weeks if not caught at the estimate stage. We flag it before the tools come off the truck. It’s not a formality; the board reviews cap profile, material, and color. On a 1930s Colonial in Bronxville’s Lawrence Park, our crew found two adjacent clay flues in a single stack. The active fireplace flue showed first-degree creosote. The long-abandoned coal boiler flue had a horizontal crack at the roofline, and the gas furnace was backdrafting into the smoke chamber. We installed a DuraFlex stainless steel liner for the fireplace, sealed the abandoned flue at the crown, and rebuilt the exposed chimney above the roof only after the village’s landmarks board signed off on the cap profile. That’s the local knowledge you don’t get from a national chain.
