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.
Fast, Reliable Chimney Liner & Rebuild Across Port Chester
Most chimney liner and rebuild work in Port Chester costs $2,400 to $7,800, and the tight attached housing here means the job is unlike anything in single-family zip codes. In the village’s pre-1940 two- and three-family homes, a single exterior chimney often carries multiple flues stacked side by side, which changes how Wendell and his crew plan every liner install and every partial rebuild. If you suspect a cracked clay liner or your neighbor’s exhaust is finding its way into your apartment, call (914) 537-6479 and we’ll set a real appointment with a real person on the other end.
Why Top Hat Chimney Is Port Chester’s Preferred Chimney Liner & Rebuild Company
Wendell Pike has been running Top Hat Chimney since 1999, and he’s been in and out of Port Chester basements, attics, and rooflines longer than most of the national franchises have even had a local phone number. When you call, the phone rings at the shop. Not a call center in another state. The sweep who shows up in a uniform with a background check is someone Wendell would sit down with at the diner on North Main Street.
Port Chester’s attached homes mean roof access can be genuinely difficult here. Narrow alleys and zero lot lines on Highland Street or along King Street don’t faze us because we’ve been navigating them for decades. We show up with the right ladders, the right flashing, and a camera that tells you the truth about your flue before anybody quotes a liner or a rebuild. The camera footage and a plain-English verdict, every time, no exceptions.
Every job gets the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Wendell back. You won’t chase anybody down a phone tree. You’ll run into him at the hardware store on Saturday.
Our Chimney Liner & Rebuild Services in Port Chester
Stainless Steel Liner
A stainless liner is the most common fix we recommend in Port Chester’s attached housing stock, because so many original clay-tile flues were never replaced when gas or oil appliances went in. We install DuraFlex stainless liners sized to the existing chimney and the appliance it’s venting. In a two-family on Abendroth Avenue, that often means running a dedicated stainless liner for a furnace while sealing off an adjacent flue that no longer serves an active appliance.

Flexible Liner
Flexible liners earn their keep in Port Chester’s older brick stacks, where the flue often bends slightly or shifts from decades of thermal expansion. Removing an old clay liner and pulling a flexible stainless one through is frequently faster and less invasive than a full rebuild, especially when the exterior brick is still sound. Wendell will tell you plainly when a flexible liner makes sense, and just as plainly when a rigid liner or a rebuild is the only honest fix.

Liner Replacement
Liner replacement in Port Chester usually means removing cracked clay-tile sections and installing a properly sized replacement flue. The coastal humidity along the Byram River accelerates the damage, and by the time mortar joints show efflorescence on the outside, the liner inside is often worse. We run the camera first, every time. You see the crack before you approve the liner. No guesswork, no surprise upcharge at the door.

Partial Rebuild
A partial rebuild in Port Chester typically tackles the top three to seven courses of brick, replacing spalled masonry and rebuilding the chimney crown with proper overhang and a quality sealant. For attached homes on Westchester Avenue, this is often the difference between a chimney that sheds water and one that leaks steadily through the party wall into both units. We pair the rebuild with new flashing when needed, because rotten flashing is what lets water into the roofline in the first place.

Wendell doesn’t sell you a brand, he installs the one that fits your flue and your budget.
Common Chimney Liner & Rebuild Problems We See in Port Chester Homes
- Shared flue cross-contamination. A single three-story exterior chimney serving three apartments is routine property here. If one unit’s gas insert exhausts into the same stack as an open, unlined wood-burning flue, carbon monoxide can push into an adjacent apartment and nobody sees it from the street.
- Hidden clay liner cracks. Original clay-tile liners from the village’s industrial manufacturing era have never been replaced in many homes, even though appliances changed hands across multiple tenancies. Decades of freeze-thaw have cracked them behind the brick, and you can’t confirm it without a camera inspection.
- Mortar joint deterioration from coastal humidity. Salt-laden air from Long Island Sound works into brick pores, then winter freeze-thaw cycles spall the faces and erode the mortar. We’re pulling apart chimneys in Port Chester that were repointed only a decade ago in drier inland towns like Harrison or White Plains.
- Unlined appliance retrofits. It’s routine to find a ground-floor gas insert or furnace that was simply vented into an old, unlined flue. That configuration violates Westchester County code and creates a live carbon monoxide risk that has nothing to do with how the fireplace looks.
Pricing for Chimney Liner & Rebuild in Port Chester, NY
A stainless steel liner installation in Port Chester typically runs $2,400 to $4,600 depending on flue length, roof access, and whether existing clay tiles need to be broken out first. A flexible liner for a straight or slightly offset flue falls in the $1,800 to $3,200 range. Liner replacement that includes removing damaged clay sections and sealing abandoned flues runs $2,800 to $5,400. A partial chimney rebuild starts around $2,900 and tops out near $6,800 when flashing replacement and crown work are included. A full rebuild of a shared stack on a larger lot-line property runs higher, usually $7,000 to $14,000. Every quote is flat-price before tools come off the truck. Senior and veteran discounts knock 10% off, and any repair over $200 takes $40 off the total. Call (914) 537-6479 for a written estimate.

FAQs - Chimney Liner & Rebuild in Port Chester
No. A gas furnace and a wood-burning fireplace must vent through separate, properly sized flues, especially in attached Port Chester homes where multiple units may share the same exterior stack. Sharing one liner violates Westchester County code and can push carbon monoxide into the living space if either appliance backdrafts. We’d run a camera, assess both appliances, and either install separate stainless liners or seal off the flue no longer in use. Call (914) 537-6479 and we’ll explain exactly what your stack needs, based on what the camera shows, not a guess.
Yes, in practice you do. When two attached homes share a party wall and a chimney stack, any rebuild that crosses the property line or affects both flues needs coordination with the adjacent owner. If your neighbor’s portion of the stack is spalling and threatening to pull your side apart, we’ll document it with photos and give you a written assessment you can hand them. The fix is often a partial rebuild on the shared upper courses, and we’ve handled plenty of these on Westchester Avenue and Abendroth Avenue where the two owners split the work. Call us for a written report you can bring to your neighbor, or have them call too and we’ll walk both units through it.
Port Chester sits on the western shore of Long Island Sound at the mouth of the Byram River, so the air here carries more salt and moisture than it does in White Plains or Harrison. That salty moisture works into brick pores and mortar joints. When winter freeze-thaw cycles hit, the trapped water expands and turns small hairline liner cracks into open gaps. The same moisture makes creosote cling harder to the liner walls, which corrodes unlined flues even faster. It’s not marketing spin, it’s what the camera shows when we compare stacks a few blocks from the Sound to identical-era chimneys ten miles inland.
You’ve got a code violation on your hands, and potentially a dangerous one. An unlined old flue carrying gas exhaust can leak carbon monoxide into the upper units, especially if that flue was never separated from adjacent open flues. We see this exact configuration constantly in Port Chester’s pre-1940 two- and three-family homes. The fix is a properly sized stainless liner for the gas insert, and sealing any abandoned flues at the chimney crown so nothing cross-contaminates. Your flue doesn’t care how the fire looks. It cares how it breathes. Call (914) 537-6479 and Wendell will walk you through what the camera finds and what actually needs to happen next.
You’re describing a shared-stack cross-contamination problem, and it’s more common in Port Chester than in most villages because of the attached housing stock. The smell means exhaust gases from the neighboring unit are backdrafting into your flue or leaking through a cracked liner, which is exactly the situation where a camera inspection has to happen before anyone proposes a fix. The answer is usually a dedicated liner for each active appliance and sealing off any flue that’s no longer serving one. Call us for a camera inspection of the whole stack, (914) 537-6479, and we’ll document what’s happening so you and your neighbor can make an informed decision together.
If your Port Chester chimney hasn’t been looked at in a year or longer, call (914) 537-6479 for a camera inspection and a straight answer. A liner or rebuild here is a different job than it is in the single-family suburbs, and it’s one we’ve been doing since 1999. Top Hat Chimney serves all of Port Chester, including the areas around Abendroth Avenue, Westchester Avenue, King Street, and Highland Street. Estimates are free, pricing is flat before we start, and the 90-Day Done Right Promise is in writing.
