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 Islip Terrace
Chimney liner replacement in Islip Terrace typically runs $2,400 to $6,200 for a stainless steel liner pulled through an existing flue, while a full chimney rebuild from the roofline up lands between $7,500 and $16,000 depending on height and access. Those are real numbers for this hamlet, not national averages. If you’re reading this from a cape off Connetquot Avenue or a ranch near the high school, you live in one of the densest concentrations of 1950s-to-1970s dual-purpose chimneys in Suffolk County, and that changes what your flue needs. Wendell Pike and his crew at Top Hat Chimney have been scoping, lining, and rebuilding these exact stacks since 1999. Call (934) 935-3847 and you’ll get a live person, a straight answer, and a number that won’t change at the door.
Why Top Hat Chimney Is Islip Terrace’s Preferred Chimney Liner & Rebuild Company
Wendell puts his name on every job. You’ll see it on the estimate, on the invoice, and on the 90-Day Done Right Promise we stamp on every single liner and rebuild. If it’s not right, one call brings him back. No claims department. No regional manager. The guy who pulled your liner is the guy who answers.
We work Islip Terrace every week. That matters because the chimneys here have a personality all their own. The original clay tile liners in these postwar Capes and split-levels were sized for oil-fired boilers, not the gas furnaces half the hamlet converted to years ago. We know that before we even ring the bell, and it changes what we look for when the camera goes down the flue. Ask anyone on your street about the last chimney crew that showed up and started talking about a $12,000 rebuild before they’d even pulled a scope. That’s the exact opposite of how we work. The camera footage and a plain-English verdict, every time, no exceptions.
We also show up when we say we will. Islip Terrace is a tight grid, and most of our calls here are within 15 to 20 minutes of the shop. Wendell’s crew is background-checked, uniformed, and you’re told who’s coming before the truck parks. If something slips, you get a call. That’s it. No center that doesn’t know your name, no voicemail box after 5 p.m. The phone rings and a person answers, around the clock.
Our Chimney Liner & Rebuild Services in Islip Terrace
Stainless Steel Liner
When we pull a stainless liner through an Islip Terrace chimney, it’s almost always because the original clay tile is cracked, displaced, or glazed beyond saving. A 316-grade stainless liner gives that oversized oil-era flue a correctly sized exhaust path for whatever is venting into it now, whether that’s a gas boiler or the occasional fireplace fire. For homes near Great South Bay’s humidity, stainless also handles the condensation that a clay liner simply can’t. We install liners from DuraFlex and Copperfield and warranty the material and the workmanship.
Flexible Liner
Most Islip Terrace chimneys have offsets in the stack, especially the split-levels where the flue snakes around a second-floor girder. A flexible liner follows those bends without cutting into the brick. It’s the right tool for a lot of the ranches off Spur Drive South and the capes near the Islip Terrace border with East Islip. Flexible doesn’t mean flimsy. We only pull brands that hold up to the corrosive condensation these gas-converted flues produce season after season.
Liner Replacement
Here’s the sequence we see constantly in Islip Terrace: a homeowner converts to gas heat, the old clay tile flue is now venting lower-temperature exhaust, condensation soaks the tile, and the tile cracks. The homeowner doesn’t know anything’s wrong because gas exhaust is invisible and the fireplace still draws okay a couple times each winter. Then we put a camera down there and there are three vertical cracks and a glazed creosote shell. Liner replacement is not a scare tactic here. It’s the single most common repair on these homes. We remove the damaged tile, resize the flue with a stainless liner, and seal it top to bottom.
Partial Rebuild
When the top courses of brick above the roofline are spalling, loose, or leaning, you don’t always need the whole stack torn down. A partial rebuild takes it from the roofline or the attic and rebuilds only what’s failing, then we pour a proper crown with a drip edge so water stops working into the mortar. In Islip Terrace, the freeze-thaw cycles off the bay are brutal on exposed brick. A crown repair without a partial rebuild, or a partial rebuild without addressing the crown, is a job you’ll pay for twice. We’d rather do it once and have you call us in five years because you want to, not because you have to.

Trusted Brands We Service in Islip Terrace
We install and service liners from DuraFlex, Copperfield, and Famco, and we use HeatShield for resurfacing when the old clay is intact enough to save.

Common Chimney Liner & Rebuild Problems We See in Islip Terrace Homes
Every hamlet has its failure modes. Here’s what we find most often in Islip Terrace specifically:
- Original oil-era clay tile flues cracking after gas conversion. The flue was sized for a hot oil exhaust. Gas exhaust is cooler and wetter. That condensation soaks into the clay, and the seasonal temperature swings from the bay finish the job. The cracks are there long before you smell anything.
- Third-degree creosote glaze from seasonal fires in oversized flues. Your flue doesn’t care how the fire looks. It cares how it breathes. When the flue is too big for the fire, wood smoke cools too fast and creosote hardens into a tar-like glaze that a brush can’t remove. We see this on nearly every Islip Terrace chimney that still has its original tile liner and sees occasional fireplace use.
- Spalling bricks and eroded mortar joints on the exposed crown. The humidity off Great South Bay plus the nor’easter freeze-thaw cycles chew through mid-century mortar. Bricks flake, joints open up, and water gets behind the chimney facade. Leave it and a crown repair becomes a partial rebuild becomes a full rebuild.
- Offsets in split-level flues that make old, brittle tile liners especially prone to displacement. The mid-century split-levels around Waverly Avenue and the side streets off it often have flue bends that put uneven pressure on aging clay. A shifted tile blocks the exhaust path and sends carbon monoxide back into the house. That’s not a leak you can see or smell until it’s serious.
Pricing for Chimney Liner & Rebuild in Islip Terrace, NY
Here’s what we typically quote on Islip Terrace jobs in 2026. A stainless steel liner replacement, including removal of the old clay tile, runs about $2,400 to $5,800 depending on the flue height and how much tile needs to come out. A flexible liner for an offset or angled stack lands in that same range, closer to $2,800 to $6,200. A partial rebuild of the exposed top courses, with a new poured crown, generally runs $3,500 to $7,000. A full chimney rebuild from the roofline up is $7,500 to $16,000, driven by height, scaffolding access, and whether you want a brick match or a stucco finish. That’s a wide range because a two-story center chimney near the Islip Terrace firehouse is not the same job as a single-story exterior stack off Waverly Avenue.
We give upfront pricing before a single tool comes off the truck. The number you hear on the phone is the number on the invoice. Standing offers: $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge inside the county, and 10% off always for seniors and veterans.

FAQs - Chimney Liner & Rebuild in Islip Terrace
Because these homes were built for oil. Islip Terrace’s postwar housing boom packed the hamlet with Capes, ranches, and split-levels whose chimneys were designed to vent hot, dry oil exhaust. When a homeowner converts to gas, the exhaust is cooler and wetter. That condensation soaks into the original clay tile, and after a few winters of freeze-thaw cycles off Great South Bay, the tile cracks. It’s not a defect in your chimney. It’s a mismatch between what the flue was built for and what it’s venting now. The fix is a stainless liner sized correctly for the gas appliance. Call (934) 935-3847 and we’ll scope it and show you exactly what’s happening in your flue.
First-degree creosote is a brush job. Third-degree creosote is a glaze. Catch it early and a cleaning handles it. If it’s already become a hard, glossy layer baked onto the clay, no brush on earth is taking that off without damaging the liner underneath. And if that liner is already cracked from gas condensation, cleaning it just gives you a cracked liner that looks cleaner. We won’t tell you to replace a liner because it’s dirty. We’ll tell you to replace it when it’s glazed, cracked, or displaced. Call (934) 935-3847 for a camera inspection and a straight answer.
When we scope the interior for a liner quote, we’re also looking at the crown from the roof. If the crown is cracked, spalling, or pulling away from the brick, water is already getting into the stack. Installing a new liner in a chimney with a failing crown is like putting new siding on a house with a leaking roof. It’ll fail again within five years. In Islip Terrace specifically, the bay humidity and freeze-thaw cycles make crown deterioration almost inevitable after 50-plus years. So we check it every time and tell you if the crown can wait or if it should be done with the liner. No surprises. Call (934) 935-3847 to book an inspection.
Yes, a properly sized flexible stainless liner handles a wood fireplace venting through a gas-converted flue. The key word is sized. The old oversized oil-era flue was too large for wood smoke to reach proper draft temperature, and that’s why creosote glazed on the old clay so fast. A correctly sized liner lets the fireplace fire burn hot enough to push smoke and creosote up and out. We install flexible liners from DuraFlex and Copperfield, and we’ll confirm the installation with a camera after the pull. Call (934) 935-3847 and Wendell will walk you through what your fireplace needs.
Best case, the crack worsens and the repair gets more expensive. Worst case, exhaust backs into the house, and carbon monoxide doesn’t give you a warning. In Islip Terrace’s tighter lots, a compromised chimney that vents gas exhaust into an attic or a bedroom is a real risk, and it’s not one you notice until it’s serious. If you already know your liner is cracked, waiting doesn’t improve it. These mid-century stacks deteriorate season by season, especially with the moisture off Great South Bay. Call (934) 935-3847. One camera inspection gives you the answer and a dollar figure. Then you decide.
