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.

Why Top Hat Chimney Is Westchester County’s Preferred Fireplace Services Company
Westchester County has more pre-war housing stock than almost anywhere north of the Bronx, and that changes how fireplace work should be done. A 1930s Tudor in Bronxville with a multi-flue masonry chimney is a different animal from a 1990s colonial in Somers, and a sweep who treats them the same will miss things. Wendell has worked this county since 1999, and he puts his name and license number on every job. The 90-Day Done Right Promise is in writing on every invoice: if something isn’t right, one call brings him back, no charge.
We answer the phone around the clock, and it may be Wendell himself on the line at 10 p.m. We give you a real arrival window and call if it slips. The price we quote before a single tool comes off the truck is the price on the invoice, and that’s a promise we’ve kept for over 29 years. If you already have a written estimate from another company, bring it to us for a free second opinion. We’ll go over it line by line and tell you if the work is even needed.
Our Fireplace Services in Westchester County
Gas Fireplace Service
Gas fireplaces across Westchester County need more than a dusting. We clean burner assemblies, check gas connections for leaks, test thermocouples and thermopiles, and verify venting so carbon monoxide goes outside, not into your living room. In older village homes, gas logs were often installed into fireplaces originally built for wood, which means venting and clearance issues that a routine cleaning won’t catch. A gas fireplace service call in Westchester County typically runs $189-$289.
Wood Burning Fireplace
Wood burning fireplaces in Westchester County see heavy use from October through March, and the creosote they produce is what causes chimney fires. First-degree creosote is a brush job. Third-degree is a glaze, and that’s a different conversation. We sweep the firebox, smoke chamber, damper, and full flue, then show you camera footage of what we found. Once a year, burn or no burn. Chimneys break in the off-season too. A standard wood fireplace cleaning in Westchester County comes in at $219-$349 for a single flue.
Fireplace Insert
Fireplace inserts are common in Westchester County because they turn a drafty, inefficient masonry fireplace into a real heat source. We install and service wood, gas, and pellet inserts, and we’re particular about liner sizing, because an insert connected to an oversized clay flue will condense creosote and acid. We work with DuraFlex and Olympia Chimney liners, and we’ll pull the necessary local permits and handle the HOA paperwork where it applies. Insert installation in Westchester County typically runs $3,500-$7,800 depending on liner length and finish work.
Damper Repair
A bad damper is the leading cause of a fireplace that smokes back into the room and a flue that leaks air all winter. In Westchester County’s older Colonials and Tudors, we regularly see original cast-iron dampers rusted through or warped from decades of heat. We replace or repair top-sealing and throat dampers, and we’ll show you the problem on camera before we touch anything. Damper repair in Westchester County runs $250-$550, and we keep common replacement parts on the truck so it’s usually one visit.
Firebox Repair and Fireplace Conversion
Firebox repair deserves its own section because it’s the job most often misdiagnosed in Westchester County. If mortar joints between firebrick are crumbling, or a brick has shifted, heat can reach the framing behind the firebox, and that’s a house fire waiting for a cold night. We do full and partial firebox rebuilds using refractory mortar rated for direct flame contact. Firebox repair work in Westchester County ranges from $450 for minor repointing to $2,500-$4,000 for a full rebuild.
Fireplace conversion is the other big one. Many Westchester homeowners want to switch from wood to gas, or from an open fireplace to a sealed insert. The conversion itself is straightforward, but getting the liner, venting, and gas line sizing right makes the difference between a fireplace that works for 20 years and one that backdrafts every January. We’ll walk you through what your specific house needs, and if you qualify for the 10% senior or veteran discount, it applies here too.
Trusted Brands We Service in Westchester County
We install and service equipment from HeatShield, Gelco, and Famco, which means we can match the liner or component your existing system was built with, instead of forcing a universal part into a 70-year-old flue. We stock common replacement parts for Westchester County homes so a damper repair or gas valve replacement doesn’t mean waiting a week for shipping. If you’re replacing a liner or resurfacing a damaged flue, we’ll recommend the brand that fits your chimney’s actual condition, not whichever box is on the truck.
Common Fireplace Services Problems We See in Westchester County Homes
- HOA and architectural review stop-work orders: In villages like Bronxville and parts of Tarrytown, changing a visible chimney cap or crown requires a Certificate of Appropriateness from a local review board. Crews that skip this check get stopped mid-job, and the homeowner waits weeks.
- Shared flues in attached homes: Townhouses and condos across White Plains and Mount Vernon often have stacked or shared chimney stacks with multiple flues. If the sweep doesn’t confirm which flue serves your fireplace, they clean the wrong one and your real flue stays dangerous.
- Oil-to-gas conversion leftovers: Pre-1950s homes throughout Westchester County had oil boilers venting through large clay flues. When the boiler got converted to gas, the flue stayed oversized, which causes creosote condensation, acidic moisture, and backdrafting. That legacy shows up as fireplace problems now.
- Hudson River freeze-thaw damage: Homes in Tarrytown, Dobbs Ferry, and Hastings-on-Hudson sit in a persistent moisture corridor off the river. Freeze-thaw cycles erode crown mortar and crack flue tiles faster than inland towns see, and that water ends up in the firebox.

HOA Approvals, Shared Flues, and the Conversion Legacy
This is the part generic fireplace pages skip, and it’s the part that matters most in Westchester County. If you live in a historically designated village like Bronxville or parts of Tarrytown, and the work changes what’s visible from the street, a cap change or crown replacement, you likely need a Certificate of Appropriateness from the architectural review board before we start. We flag this at the estimate stage and handle the filing for you. It’s a regulatory layer that catches people off guard, and it’s almost unheard of in Rockland or Putnam counties. Technicians who don’t know Westchester County’s village rules create delays measured in weeks, not days.
The second piece is shared chimneys. In attached homes across White Plains and New Rochelle, a single chimney stack often carries multiple flues, one for your fireplace, one for a neighbor’s, one for an old boiler. We camera-scan to confirm which flue is yours before we clean or repair anything. Getting this wrong means cleaning the wrong flue and leaving a blocked one in service. We don’t guess.
And then there’s the conversion legacy. Westchester’s stock of 1920s-1950s Colonials, Tudors, and stone Gothics was built with large multi-flue masonry chimneys serving both ornamental fireplaces and coal or oil boilers. When those boilers became gas furnaces, the oversized clay flues stayed. An oversized flue cools exhaust gas too quickly, which condenses creosote and acid inside the chimney instead of venting it out. That’s why a fireplace that worked fine for 50 years suddenly backdrafts or shows firebox damage. Chimney cleaning in Westchester County is inseparable from diagnosing this conversion legacy, and we look for it on every job.
In a 1930s Tudor in Bronxville, our crew was called for a gas fireplace service after the homeowner reported a persistent backdraft odor. We found the original clay tile flue had been left oversized after an oil-to-gas conversion, causing creosote condensation and acidic moisture damage to the firebox. We coordinated with the property manager to obtain the required Certificate of Appropriateness, then installed a properly sized DuraFlex stainless steel liner and repaired the damper, eliminating the backdraft and restoring safe operation.

FAQs - Fireplace Services in Westchester County
Yes, in many Westchester County incorporated villages, especially Bronxville, Scarsdale, and parts of Tarrytown, visible changes to a chimney cap or crown require approval from a local architectural review board or landmarks commission. The specific trigger is whether the work is visible from the street or alters the historic appearance of the structure. We check this during the estimate and file the necessary paperwork on your behalf, so the job doesn’t stall mid-way. If you’re unsure whether your project needs review, call (914) 537-6479 and describe the work; we’ll tell you what applies in your village.

We run a camera down each flue and confirm which one connects to your fireplace before we clean or repair anything. This matters because many attached homes in White Plains, Mount Vernon, and New Rochelle have stacks with two or three separate flues, and cleaning the wrong one is a wasted visit. The camera footage also shows us the condition of your specific flue, not the neighbor’s. If we find a blocked secondary flue, we’ll document it and let you and your management company know in writing.

Because the flue that used to vent your oil boiler is almost certainly oversized for anything connected to it now, and oversized flues cool exhaust too quickly, which causes creosote condensation, acid inside the chimney, and backdrafting into the room. In Scarsdale, Larchmont, Pelham, and most of Westchester County’s pre-war housing, this conversion legacy is the hidden cause behind a lot of fireplace odor and firebox damage. The fix is usually a properly sized liner, and we’ll show you the problem on camera before recommending it. Call (914) 537-6479 for an inspection, and we’ll explain what your specific chimney shows.

Yes, and we see it every year. The Hudson River corridor creates a moist microclimate where repeated freeze-thaw cycles erode crown mortar and crack clay flue tiles faster than inland Westchester towns experience. When water gets into the firebox and freezes, spalled brick and crumbling joints follow. The fix is crown sealing and, where needed, flue repair before winter sets in. If you’re in Tarrytown, Dobbs Ferry, or Hastings-on-Hudson and haven’t had your crown checked in a few years, that’s a good reason to call now rather than after the first thaw.

A routine cleaning doesn’t require a permit anywhere in Westchester County, so that can be scheduled immediately. Repairs that alter visible exterior elements, cap changes, crown replacements, repointing that changes appearance, may, in historically designated villages like Bronxville and parts of Tarrytown, trigger a Certificate of Appropriateness review that can add a few weeks to the timeline. We build that into the schedule up front and handle the filing, so the delay is managed, not discovered mid-job. If you want to know whether your specific repair needs review, call (914) 537-6479 with the address and we’ll check before you commit.
