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 Harrison
Chimney liner installation and rebuild work in Harrison runs from about $2,800 for a straightforward stainless steel liner replacement to $9,000-$14,000 for a full masonry rebuild when freeze-thaw damage has gotten ahead of the structure. The liners in Harrison’s older homes fail in a predictable way: oversized flues left over from oil-to-gas conversions trap acidic condensate, and the deterioration shows up long before a homeowner sees a single brick move. We’ve been working in Harrison and southern Westchester long enough to know exactly what those chimneys look like inside, and we’ll show you the camera footage before we recommend spending a dollar. Call Wendell and his crew at (914) 537-6479, and you’ll get a live person, an honest read, and a price you can hold us to.
Why Top Hat Chimney Is Harrison’s Preferred Chimney Liner & Rebuild Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone himself half the time. That matters in Harrison, where the houses are older, the chimneys are original, and the work rarely fits a tidy checklist. Homeowners along Harrison Avenue, in the village proper, and over in Purchase don’t need a sales pitch. They need a sweep who has been inside enough 1920s brick colonials to know what the flue condition means before he even sets the ladder.
We’re not a franchise that rotated into Westchester last spring. Wendell puts his name and license number on every job, and the 90-Day Done Right Promise is in writing. If something isn’t right, one call brings him back. No argument, no runaround. That’s the whole point of hiring a local owner-operator: you’ll run into him again at the hardware store, and he knows it.
Every Harrison call gets a background-checked, uniformed crew member who arrives in a real time window and calls if traffic on the Hutchinson River Parkway or I-287 throws that off. And before a single tool comes off the truck, you’ll have a firm price. The number you’re quoted is the number on the invoice.
Our Chimney Liner & Rebuild Services in Harrison
Most Harrison homes need one of a few very specific things done, and done right the first time. Here’s what we do most often in this town, and why it applies to your house specifically.
Stainless Steel Liner
For a Harrison oil-to-gas conversion home, a properly sized stainless steel liner is the single most effective fix you can make. The original flue was built for 500-degree oil exhaust. Modern gas furnaces run much cooler, and the acidic condensate eats mortar joints from the inside out. We install DuraFlex stainless liners sized to the appliance, not to the old clay tile, and we do it on the furnace side while often leaving the fireplace side alone if it’s in good shape. In Harrison village, this is the conversation we have more than any other.
Flexible Liner
Not every Harrison chimney is a straight shot. Older center-chimney colonials often have slight offsets, and a rigid liner simply won’t negotiate them. Flexible stainless steel liners handle the curve without compromising draft or trapping debris. We stock Gelco flexible liner components for fast turnaround on Harrison jobs, and we’ll show you the before and after footage so the fix isn’t just a line item on an invoice.
Liner Replacement
Clay tile liners crack. It’s what they do after sixty or eighty years of freeze-thaw cycling in southern Westchester. A cracked liner lets heat and carbon monoxide reach the masonry around it, and in a Harrison house where the chimney serves two flues, a failing liner on one side endangers the whole stack. We remove the old tile, assess the brick, and replace with stainless steel that’s sized for the actual appliance load, not the 1950 blueprint.
Partial Rebuild
Most Harrison chimneys don’t need to come down to the roofline. They need the top ten or fifteen courses rebuilt, a new crown poured, and the flashing redone. Water gets into the crown, freezes, and spalls the brick below it. A partial rebuild stops that cycle before the damage reaches the flue tiles or the smoke chamber. We’ll tell you plainly if a partial rebuild will buy you twenty years, or if the mortar bed has gone bad enough that a full rebuild is the only honest call. Wendell has no patience for selling a full rebuild when the top of the chimney is the only problem.

Trusted Brands We Service in Harrison
We install and service liners and rebuild components from DuraFlex, Gelco, HeatShield, Olympia Chimney, and Famco. That matters for Harrison homeowners because we keep common liner diameters and cap hardware in stock locally, so a liner replacement on a standard colonial flue doesn’t turn into a two-week wait for parts. When the job calls for a HeatShield resurfacing instead of a full liner pull, we’ll show you the camera footage that justifies it. You’ll know what you’re paying for and why.
Common Chimney Liner & Rebuild Problems We See in Harrison Homes
- Oversized flues after oil-to-gas conversion. The original chimney was built for an oil boiler that ran hot. The gas furnace that replaced it runs cool, and the oversized clay flue never warms up enough to push moisture out. Condensate sits on the mortar, dissolves it, and the liner starts to spall from the inside. Most Harrison homeowners never know until a Level 2 camera inspection shows the damage.
- Multi-flue stacks that get half maintained. A single chimney serving both a gas furnace flue and a wood-burning fireplace is common in Harrison village. The furnace side looks fine after conversion, so the fireplace side gets ignored. It shouldn’t. We pull third-degree creosote out of those fireplace flues regularly, and glaze like that can’t be brushed out. It’s a chemical treatment or a liner rebuild, and the annual sweep is what catches it early.
- Freeze-thaw crown damage. Southern Westchester winters cycle through freeze and thaw dozens of times each season. Old mortar crowns absorb water, freeze, and crack further each year. That water works its way down into the brick, and by the time you see spalling on the outside, the flue inside has already been wet. Harrison’s older masonry homes are especially prone because the crowns were often formed thin in the original build.
- Two flues in one stack, two very different conditions. Last winter we worked on a Tudor off Harrison Avenue where one chimney stack served both a gas furnace flue and an active wood-burning fireplace. The fireplace flue had accumulated third-degree creosote, a tar glaze a brush can’t remove, while the furnace flue showed spalling from years of condensation. We installed a DuraFlex stainless steel liner on the furnace side, rebuilt the firebox and smoke chamber, and fitted a new chimney cap, leaving the homeowner with two distinct, correctly sized flues and a clean Level 2 inspection. That’s the standard Harrison job.
Pricing for Chimney Liner & Rebuild in Harrison, NY
A stainless steel liner install in Harrison generally runs $2,800-$4,500 depending on flue height and access. Liner replacement, including removing the old clay tile, runs $3,500-$6,000. A partial rebuild, where we tear down the top courses, repoint, and pour a new crown, lands between $3,200 and $6,500. Full chimney rebuilds start around $9,000 and go up from there, mostly determined by roof access and how much scaffolding is needed. In Purchase, where estate homes often have taller chimneys and multiple fireplaces, expect the higher end of every range. We don’t pad these numbers. We show you the camera footage, give you a written quote, and you decide. Call (914) 537-6479 and Wendell or one of the crew will walk you through a real number, not a vague ballpark. A free second opinion on any written estimate is part of how we work in Harrison.

FAQs - Chimney Liner & Rebuild in Harrison
Yes, and in most cases you need one more than ever. The original flue was sized for an oil boiler that ran hot enough to push moisture out. A modern gas furnace runs cooler, so the oversized flue never fully warms, and the acidic condensate sits on the mortar joints and eats them. In Harrison village, this is the single most common reason we’re called out. A properly sized stainless steel liner solves it permanently, and until you have one, that flue is deteriorating a little more every season. Call us at (914) 537-6479 for a straight answer and a camera inspection.
Once a year, burn or no burn. Both flues need it. The furnace side can be quietly spalling from condensate, and the fireplace side can be loading up with creosote that you’ll never see from the hearth. The annual inspection catches both in the same visit. We’ve found enough third-degree creosote glazing in Harrison fireplace flues to know the risk is real. Call (914) 537-6479 and schedule the sweep. It’s far cheaper than a rebuild.
Most of the time, a partial rebuild is the right answer. If the damage is concentrated in the top courses, the crown, and the flashing, that’s where the water entry starts, and rebuilding those sections stops it. A full rebuild only makes sense when the mortar bed throughout the stack has failed or the flue tiles are so far gone that the whole structure is compromised. We’ll tell you which one you actually need, and we’ll show you the camera footage to prove it. If another company quoted you a full rebuild, get a free second opinion from us before you sign anything. Call (914) 537-6479.
First-degree creosote is a dusty, flaky deposit that brushes off with a standard sweep. Third-degree creosote is a hard, shiny glaze that has baked onto the flue walls, and it’s a whole different animal. It won’t brush out. It requires chemical treatment or liner replacement. In Harrison fireplace flues, especially in homes where the furnace was converted to gas and the fireplace kept getting used, third-degree creosote is common. The homeowners don’t realize the fireplace side still needs annual cleaning even though the chimney “seemed fine.” With a wood-burning fireplace in an older Harrison home, expect to deal with this eventually. Calling (914) 537-6479 gets you an honest read on which kind you have.
Yes. A cap keeps rain out of the flue, and rain is what accelerates the freeze-thaw damage that kills Harrison masonry chimneys. If your furnace flue is unlined and oversized, water plus acidic condensate is a compound problem. A stainless steel cap is one of the cheapest prevention steps you can take, far cheaper than the partial rebuild it forestalls. We stock standard sizes and can turn most Harrison cap installs around fast. Call (914) 537-6479 and ask about caps when you schedule your sweep.
