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.

AfterDuraFlex Chimney Cleaning in Westchester County, NY | Top Hat Chimney
Westchester County Chimney Cleaning & Sweep for DuraFlex systems means more than running a brush up a flue. It means knowing how a stainless liner behaves inside a 1928 Bronxville Tudor whose oil boiler became a gas furnace thirty years ago. We’ve been inside those chimneys since 1999, and we’ll tell you plainly what the liner needs and what it doesn’t. Call (914) 537-6479 for a straight answer.
Top Hat Chimney installs and services the full DuraFlex line: SS, Pro, Al29-4C, and 316Ti. We’re an independent DuraFlex service provider, not manufacturer-affiliated, and not authorized. That independence matters. We recommend what the liner actually needs, not what a franchise playbook tells us to sell. From Pelham to Peekskill, every job gets the camera footage and a plain-English verdict.
Whether you need a sweep, a Level 2 inspection, creosote removal, or chimney waterproofing around a DuraFlex liner, call (914) 537-6479. Wendell Pike and his crew will show up on time, name on the truck, price set before a tool comes off.
Why Westchester County Residents Choose Us for DuraFlex Service
Wendell grew up in San Diego, which is a fine place to be from if you don’t mind never learning much about fireplaces. He picked up the trade through the HVAC and building systems program at Palomar College in San Marcos, then spent the better part of two decades working chimneys across Westchester County, including plenty of older stone-and-brick homes up near the Teatown Lake Reservation area. He built Top Hat Chimney on a simple rule: show up, tell people exactly what he finds, and don’t recommend work that isn’t needed. If it doesn’t need doing, he’ll tell you that too.
Around here, that honesty lands different. We’ve been inside hundreds of Westchester chimneys where a DuraFlex liner was dropped into a clay tile flue built for a coal boiler. We know what the county’s humidity does to stainless, what the old mortar does to the liner’s top plate, and which repairs can wait a year. That local knowledge is the difference between a cleaning and a Chimney Repair - Westchester County conversation you actually trust.
We stock genuine DuraFlex components, not whatever the supply house had on sale. We answer our own phones, around the clock. And every completed job carries the 90-Day Done Right Promise in writing: if the work isn’t right, one call brings us back.
Common DuraFlex Chimney Cleaning Problems We Solve in Westchester County
- Creosote glazing on DuraFlex SS liners in oversized flues. Westchester’s 1920s Colonials in Scarsdale and Larchmont were built with big multi-flue chimneys. When oil-to-gas conversions left those oversized clay-tile flues serving smaller appliances, the metal liner runs cooler, and creosote condenses as a hard glaze on the inner walls instead of brushing off as dust. We use rotary whip systems sized for stainless liners to remove that glaze without scoring the metal.
- Corrosion pitting along DuraFlex Pro seam welds. High-efficiency gas furnaces produce acidic condensate. In Westchester’s river towns like Hastings-on-Hudson and Dobbs Ferry, ambient moisture compounds the problem, and we find pinhole corrosion at the seam welds on Pro liners that are only five or six years old. The fix is often a 316Ti section replacement, not a whole new liner.
- Loose slip joints in DuraFlex Al29-4C liners. Poorly insulated clay-tile chimneys put any liner through repeated thermal cycling. In Westchester’s freeze-thaw winters, those expansion and contraction cycles work slip joints loose. We see separated joints in pre-war chimneys from Pelham to Mount Kisco far more often than in newer construction. A Level 2 camera inspection catches the gap before exhaust leaks into the chase.
- Debris and mortar fall-in jamming the top plate. The county’s Hudson River microclimate accelerates crown erosion. Small pieces of spalled brick and deteriorated mortar break loose and land on the liner’s top plate or damper area, partially blocking the flue. During a cleaning, we clear that debris and flag the crown if it’s the source.
- Backdrafting on windy days in river-facing homes. Along the Tarrytown and Irvington ridgelines, wind coming off the Hudson can push exhaust back down a short or poorly capped liner. Sometimes the liner height is the issue. Sometimes the cap is wrong for the wind exposure. We diagnose it during the sweep and tell you what’s actually causing it.
DuraFlex Service in Westchester County: What Local Conditions Mean for Your Equipment
Westchester villages like Tarrytown and Dobbs Ferry sit inside the Hudson River’s freeze-thaw microclimate. Winter moisture cycles work on chimney materials year after year, and that has a measurable effect on DuraFlex liners. We find hairline cracks along liner seams in these river towns at a faster rate than we see in inland Rockland or Putnam counties. The freeze expands moisture trapped in minuscule gaps at the seam welds; the thaw releases it; a few hundred cycles later, the seam lets go. That’s why our Level 2 camera inspections in Tarrytown, Irvington, and Hastings-on-Hudson pay close attention to seam integrity, even on liners that look fine from the top.
One job from a 1929 Larchmont Tudor stays with us. A DuraFlex Pro liner serving a converted gas boiler had acidic condensate eating through an upper-third seam. The homeowner smelled exhaust in the study. We pulled the liner, swapped in a new 316Ti section, and added a custom top plate with a screened cap to keep rain from entering the flue. That home didn’t need a new chimney. It needed someone to look carefully and fix the actual problem.
Landmarks review boards add another layer in places like Bronxville and parts of Tarrytown. If your chimney is visible from the street and the liner repair requires a crown replacement or visible cap change, you may need a Certificate of Appropriateness before work begins. We flag that at the estimate stage, not after the scaffold is up. A technician from a neighboring county might not even know to ask.
DuraFlex Models & Products We Service in Westchester County
We service every major DuraFlex product line in Westchester County homes. The DuraFlex SS is the workhorse liner we see most often in 1920s through 1950s Colonials. DuraFlex Pro is built for higher-temperature applications, and we commonly find it in fireplaces that see heavy winter use. DuraFlex Al29-4C is the right choice for high-efficiency gas appliances, and we stock the connectors and caps that match. DuraFlex 316Ti is the marine-grade stainless we recommend in the river towns where moisture exposure is the real enemy.
For repairs, we always recommend genuine DuraFlex components. Third-party connectors and caps almost never match the factory tolerances, and a loose joint in a stainless liner isn’t a place to save $40. We’re also honest about when a full liner replacement is unnecessary. A corroded section can often be swapped for a new 316Ti piece. A loose joint can be re-secured. A liner with minor surface rust can get an insulation wrap and several more years of life. We’ll show you the camera footage and let you decide with the evidence in front of you.

FAQs - DuraFlex Chimney Cleaning in Westchester County
Once a year, burn or no burn. The conversion is exactly why the annual check matters. An oversized clay flue mated to a modern gas appliance runs cooler, which lets creosote and moisture condense on the liner walls. That buildup doesn’t announce itself. We find it with the camera. Call (914) 537-6479 if you can’t remember the last sweep.
If you burn wood, yes. The heating system doesn’t matter. What matters is what goes up the flue. Wood produces creosote. First-degree creosote is a brush job. Third-degree is a glaze; catch it early.
Usually, yes. If the corrosion is isolated to one section, we can pull that section and replace it with a 316Ti piece, then add a rain cap if water entry contributed. We don’t recommend a full teardown unless the surrounding masonry has failed or multiple sections are compromised. No cap changes go on a Tarrytown landmark-visible chimney without checking whether the landmarks board gets a say.
Sometimes, but not always. 316Ti resists corrosion better in the river air, but backdrafting is more often a height, cap, or flue-sizing issue. We’ll camera the liner and check the termination before recommending a switch. Upgrading the wrong component costs money and doesn’t fix the draft. A free estimate gets you the real diagnosis: (914) 537-6479.
Yes. Multi-flue chimneys in Scarsdale’s older Colonials are common, and each flue gets its own inspection and its own cleaning. The gas fireplace flue and the wood insert flue have different buildup patterns and different clearance requirements. We document both separately, and the camera footage goes to you either way. Call (914) 537-6479 to schedule.
