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 Westbury
Chimney liner replacement or rebuild work in Westbury typically costs $2,800 to $7,400 depending on whether you need a stainless liner dropped into the existing flue, a partial rebuild of the crown and top courses, or a full teardown from the roofline up. Most Westbury homes we see are the 1945 to 1965 Cape Cods and ranches that make up the bulk of the village, and the liner problems on those houses usually trace back to one thing: the oil-to-gas switch. Flues that were sized for oil-fired boilers are either oversized for gas or cracking from seventy years of acidic condensate. Call (516) 963-1068 and Wendell will walk through what you’re seeing, and tell you straight whether it needs fixing now or can wait.
Why Top Hat Chimney Is Westbury’s Preferred Chimney Liner & Rebuild Company
We’re the locally owned, owner-operated alternative to the national chains that send a stranger with a clipboard and a script. Wendell Pike has run Top Hat Chimney since 1999, and he puts his name and license number on every job. When you call, a live person answers, day or night. It’s often Wendell himself picking up. A homeowner off Maple Avenue recently told us she’d had two other companies out before us. One quoted a full rebuild from a photo. The other never sent the camera footage he promised. We sent the footage of her crown cracks the same afternoon, told her the flue tiles were still serviceable, and did a Chimney Liner & Rebuild on just the top eight courses. She now has our number on her fridge. That’s how we work in Westbury.
We don’t do bait pricing. The number you hear on the phone is the number on the invoice, and if the work isn’t done right, our 90-Day Done Right Promise brings us back. It’s in writing on every job.
Our Chimney Liner & Rebuild Services in Westbury
Stainless Steel Liner
The most common liner we install in Westbury is a stainless steel one, typically DuraFlex or Gelco, dropped inside the old clay tile flue. On a 1950s cape with a spalled liner, this gives you a continuous, correctly sized passage for exhaust without knocking down the chimney. For gas furnaces that were converted from oil, the old 8×12 clay flue is too wide for today’s gas draft requirements. A properly sized 5-inch or 6-inch stainless liner corrects that, and keeps condensation from eating the mortar joints from the inside out.
Flexible Liner
Flexible liners are our go-to for Westbury homes with offset flues, the kind you find in a lot of split-levels off Post Avenue and Ellison Avenue where the firebox doesn’t sit directly below the chimney top. A rigid liner won’t make the bends without cutting into masonry. A flexible stainless liner snakes through the offsets, holds up to wood-stove heat, and gets you burning safely without rebuilding the whole stack.
Liner Replacement
If your existing liner is cracked, spalled, or the wrong size, the repair isn’t a patch. It’s a replacement. In Westbury’s mid-century housing stock, original clay tile liners are now sixty to eighty years old, and the freeze-thaw cycling off the Atlantic has done quiet damage. Water gets into hairline cracks in the crown, freezes, widens those cracks, and next spring the liner tiles start flaking. We pull the old liner when possible and replace it, rather than lacquering over a problem that’s already structural.
Partial Rebuild
When the crown is spalled and the top three to eight courses of brick are loose or leaning, we don’t tear the whole stack down unless we have to. A partial rebuild replaces the compromised section, pours a proper concrete crown with an overhang and drip edge, and sets a cap that stops water entry. On the ranch homes common to Carle Place and the streets around Eisenhower Park, this is often half the cost of a full rebuild and buys decades of service.

Trusted Brands We Service in Westbury
We install and service liners from HeatShield, DuraFlex, Gelco, and Olympia Chimney, plus Famco caps and Copperfield products. Because Westbury homes skew toward mid-century masonry, we keep common liner diameters and crown materials stocked and ready to go, which means we’re not waiting a week on a part while your flue sits open to Long Island weather. If you’ve got a specific brand installed, we’ll tell you what we think of it honestly, including whether it’s worth repairing or better replaced. Wendell has been inside enough of these chimneys to know which liners hold up on Long Island’s freeze-thaw cycles and which ones were never built for Atlantic weather.
Common Chimney Liner & Rebuild Problems We See in Westbury Homes
- Oversized clay tile flues from oil-to-gas conversions. The 2000s and 2010s saw a wave of oil-to-gas switches across Westbury. Many homeowners never relined. The old 8×12 flue is now double the cross-section the gas appliance needs, which strangles draft, drops flue temps, and leaves acidic condensation sitting in the tile joints year round. That condensation is now the single biggest cause of liner failure we see in the village.
- Freeze-thaw crown damage off the Atlantic. Westbury sits roughly 5 to 7 miles from the South Shore, and winter storms push enough wet snow onto these flat and low-pitch ranch chimneys to soak a cracked crown every few weeks. Water gets in, freezes, and widens hairline cracks in the liner tiles beneath. By spring, the flue is leaking gas and the mortar joints are powder.
- Third-degree creosote glaze on wood-stove liners. We see heavier creosote loading on the rural side streets of Westbury where wood stoves are primary heat, not ambiance. Third-degree glaze bonds to the liner, and when flue temps spike, that glaze drives liner temperatures into a range that kills stainless, let alone old clay. Undersized liners with heavy stove use are a formula for a chimney fire.
- Real-estate inspection failures on unconverted flues. Home sales surface the problem. The code inspector flags the original clay flue as noncompliant for the gas appliances it now serves, and the deal stalls. We get a lot of calls two weeks before closing from Westbury homeowners who never thought about their chimney until the inspection report came back. Last-minute relines are doable, and we keep backlog room for exactly this.

FAQs - Chimney Liner & Rebuild in Westbury
Yes, and here’s why. Your 1950s chimney was built with a clay flue sized for an oil boiler, usually 8×12. Gas appliances need a much narrower flue. When you run a gas furnace through an oversized flue, the exhaust cools too fast, draft drops, and water condenses inside the flue. That condensation is mildly acidic, and after ten to fifteen years, it eats the mortar joints between the clay tiles. We pull a Level 2 camera inspection and show you the footage. If the joints look solid, you may have time. If they’re spalled and flaking, the liner needs replacing before flue gas starts leaking into the wall cavity. Call (516) 963-1068 for a free estimate and we’ll tell you which side of that line you’re on.
Almost always, yes. A stainless liner drops inside the existing flue from the top down, which means no demolition of the brick and no scaffolding on your roof for a week. We do it in a day in most Westbury homes. The cases where we need to break out the old clay tile first add some time, but even then the chimney stays standing. The only time a full rebuild is necessary is when the brick itself is structurally failing, and we’ll show you the evidence before quoting that.
We install stainless liners, usually Gelco or DuraFlex, sized to the stove’s actual output, and we insulate the chase so flue temps stay high enough to prevent creosote from condensing. The homes around Westbury that heat with wood full-time load the liner far harder than a weekend fireplace, so the liner has to be heavy-wall stainless, correctly sized, and insulated. We also walk you through burning practices that cut creosote buildup, because the liner is only part of the equation.
It does, indirectly. The liner itself is inside the flue, so the storm doesn’t touch it directly. What the Nor’easter does is drive wet snow onto a cracked crown and into the flue, where it freezes and expands in the tile joints. Repeated freeze-thaw cycles widen hairline cracks in the liner until the flue starts leaking gas. A good crown and cap stop most of it, and that’s why we replace the crown whenever we reline in Westbury. It’s the difference between a fifteen-year liner and one that fails in five.
Potentially, but not always. Oil exhaust is hot and produces less condensation than gas, so original clay flues that stayed on oil often fare better than converted ones. The factors are the age of the tile, whether the crown has been letting water in, and whether the flue size still matches the boiler. We’ll run a camera up and show you the actual condition. If it’s sound, Wendell will say so, and he’ll be the first to tell you when work can wait. If it’s not, you’ll see the cracks in the footage yourself and can make the call with the evidence in front of you. For a free second opinion on any written estimate, call (516) 963-1068.
