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 Elwood
Chimney liner and rebuild work in Elwood typically runs between $2,800 and $9,500 depending on whether you need a stainless steel liner installed in an existing flue or a partial teardown and reconstruction of the brick chase. Most liner replacements we do in Elwood take one day. If the crown and upper brickwork are sound, relining alone is usually all it takes. Call (631) 318-8656 and Wendell will give you a straight answer about which one your chimney actually needs, before any tools come off the truck.
Elwood is home turf to us. The split-levels off Jericho Turnpike, the Capes along Elwood Road, the ranches tucked back from Burr Lane. We know these chimneys because we’ve been inside them. The 1960s brick chases with two flues sharing one stack. The original clay tile liners that were never meant to see a gas boiler. The crowns crumbling from salt air a few miles off Huntington Bay. When you call for Chimney Liner & Rebuild, the person who answers may well be the same one who shows up at your door. Wendell has put his name on this work since 1999 and he runs into you again at the supermarket.
Why Top Hat Chimney Is Elwood’s Preferred Chimney Liner & Rebuild Company
We’re the locally owned, owner-operated option, not a franchise that rotated in last spring and will be gone by fall. Wendell Pike started Top Hat Chimney in 1999 and has worked this same stretch of Suffolk County ever since. His license number is published, his phone is answered by a live person around the clock, and the 90-Day Done Right Promise is stamped on every job in writing. If it’s not right, one call brings him back.
Ask anyone on your street. Elwood homeowners call us because the national outfits quote one price on the phone and another at the door, while we hand you an upfront number before a single tool comes off the truck. That number is the one on the invoice. We don’t have a call center. We don’t send a stranger. Background-checked, uniformed, and the sweep who arrives gives you a real arrival window, and calls if it slips. In a hamlet like Elwood, where most of the housing stock was built between 1950 and 1975, that matters. These chimneys are 50 to 70-plus years old now. You want someone who knows what’s inside them, not someone learning on yours.
When we serve Elwood, we’re not driving in from some other county. Dispatch and scheduling are coordinated from our New York City office, and crews serve Elwood locally. We can get to a home off Warner Road or down near the Dix Hills border without a half-day of windshield time.
Our Chimney Liner & Rebuild Services in Elwood
Stainless Steel Liner
Most Elwood homes that converted from oil to natural gas still vent into the original clay tile flue. That oversized tile is a problem. The gas appliance runs cooler than the oil furnace did, which means flue gases condense inside the tile instead of carrying up and out. The result is acidic condensate that eats the clay from the inside. A properly sized stainless steel liner, usually DuraFlex, solves it. The old tile stays in place as a chase, and the new liner handles the low-heat appliance the way the original never could. We install and service DuraFlex and Copperfield liners and we size them to the appliance, not to whatever tile happens to be there.
Flexible Liner
Flexible liners make sense when the existing flue has offsets or bends, which is common in the shared brick chases of Elwood’s 1960s split-levels. If the flue runs straight enough, we’ll say so and use a rigid or semi-rigid system. If it snakes, flex is the right call. We don’t push flex on a straight flue just because it’s easier to haul up a ladder. You’ll see the reasoning for whichever we recommend, backed by camera footage.
Liner Replacement
Liner replacement in Elwood usually means one of two things. Either the original clay tile liner has deteriorated to the point that spalled clay and crumbled mortar are blocking the flue, or a previous stainless liner has burned through at a seam. Both are failures we see regularly. The first is rampant in oil-to-gas conversions: the acidic condensate eats the mortar between tile sections, then flue gas leaks into the chase. The second shows up on liners that were undersized or cheaply installed. Either way, we camera-scope the flue before recommending anything. The footage and a plain-English verdict, every time, no exceptions.
Partial Rebuild
A partial rebuild addresses the top of the chimney: the crown, the uppermost courses of brick, the flue tile extending above the crown line. In Elwood, salt-laden air off Huntington Bay accelerates spalling on exposed brick, and freeze-thaw cycles widen the cracks winter after winter. When the top few feet are compromised, relining the flue doesn’t fix the water getting in at the top. We rebuild from the roofline up, pour a proper concrete crown with an overhang and drip edge, and leave you with a chimney that sheds water instead of drinking it.

Trusted Brands We Service in Elwood
We work with brands we trust because we’re the ones standing behind the install. That means DuraFlex stainless steel liner systems, Copperfield caps and chase covers, and HeatShield resurfacing products when a liner can be saved rather than replaced. We keep common components on the truck for Elwood jobs, so a standard liner install doesn’t sit waiting on a parts order. If you have an existing liner from one of these brands, we service it. If you’re comparing options, we’ll tell you which one fits your chimney without pushing the most expensive system on the shelf. Liner choice comes down to appliance type, flue dimensions, and condition, not commission.
Common Chimney Liner & Rebuild Problems We See in Elwood Homes
- Oil-to-gas conversions never relined. A gas boiler or furnace vents cooler flue gases into an oversized clay tile flue. Acidic condensate forms, coats the tile, and eats the mortar joints. This is the number one liner failure we see in Elwood gas-converted homes, and it’s usually found by camera, not by eye.
- Salt-driven crown spalling. Elwood sits close enough to Huntington Bay and the Sound that salt-laden air settles on exposed brick crowns. The salt works into the mortar, freeze-thaw cycles do the rest, and water starts moving down through the flue. Once water gets behind the crown, the damage accelerates fast.
- Shared flue chases hiding a second failure. This typical Suffolk County split-level configuration puts a fireplace flue and a heating-appliance flue in the same brick chase. A homeowner sees a clean fireplace flue and assumes the chimney is fine. The boiler flue behind it can be crumbling. Both flues need to be scoped.
- Third-degree creosote on wood-burning flues. First-degree creosote is a brush job. Third-degree is a glaze. In Elwood homes that still burn wood as primary or supplemental heat, we catch glazed, tar-like creosote that a standard sweep won’t remove. Relining may be the only safe fix once the glaze has compromised the flue.
Pricing for Chimney Liner & Rebuild in Elwood, NY
Here are honest numbers for the Elwood market. A stainless steel liner install, including the liner, top plate, rain cap, and labor, typically runs $2,800 to $5,200, depending on flue height, liner diameter, and access. Liner replacement that involves removing spalled clay tile first can push to $3,500 to $6,500. A partial rebuild, crown and top courses, runs $1,800 to $3,400 when done alongside a reline. A full chimney rebuild from the roofline up on a mid-century Elwood home generally lands between $7,000 and $12,000. The flue doesn’t care how the fire looks; it cares how it breathes.

FAQs - Chimney Liner & Rebuild in Elwood
Usually yes, because the old clay tile liner wasn’t sized for the gas appliance now venting into it. An oil furnace burned hot enough to push flue gases up and out. Your gas boiler runs cooler, so those gases condense inside the tile and form acidic condensate that eats the mortar from the inside. The liner can look fine from the top while failing at the upper third, which is exactly what we find on gas-converted Elwood split-levels nearly every time. The only way to know is a camera scope. If it’s not relined, you’re venting flue gas into the brick chase. Call (631) 318-8656 and we’ll scope it before recommending anything. Estimates are free.
Because Elwood sits only a few miles south of Huntington Bay and the Long Island Sound, and the prevailing air carries salt that settles on exposed brick and mortar. Salt is hygroscopic, it holds moisture against the masonry. When temperatures drop, that moisture freezes and expands inside the mortar joints and brick faces. Over years of freeze-thaw cycling, the top courses spall and the crown opens up. Homes further inland, away from the salt influence, degrade slower. It’s one reason we emphasize pre-season inspections here specifically, before the first sustained cold snap. If your Elwood crown is spalling, get it looked at before water gets behind the brick. Call for a free estimate.
In most cases in Elwood, yes. Third-degree creosote is a hard glaze, not a brush job, but if the underlying flue and surrounding brick chase are structurally sound, removing the glaze and installing a properly sized stainless liner is the fix. You don’t need to tear down a chimney just because the creosote glazed over. But if the glaze has been burning hot enough to crack tiles or the chase has shifted, a partial rebuild may enter the conversation. We camera-scope first. The footage and a plain-English verdict, every time. If we can reline and save the stack, that’s what we’ll recommend. Call (631) 318-8656 for an exact look at yours.
Not automatically, but both need to be inspected. The flue that was converted from oil to gas is the primary concern, because that’s where acidic condensate does its worst work. The other flue, if it’s still serving an oil burner or a wood fireplace, may be fine or may have its own separate issues. The danger in this shared-chase configuration is assuming a clean fireplace flue means the whole chimney is healthy. The boiler flue behind it can be crumbling invisibly. We scope both flues on every split-level job in Elwood, and we’re commonly finding the gas-converted side needs a liner while the other is still holding. Call (631) 318-8656 for a camera inspection. It’s the only way to know.
In oil-burning Elwood homes that never converted, the failure we see most is crumbling mortar between clay tile sections, especially in the upper third of the flue. Oil burns hot, and the thermal cycling over 50-plus Suffolk County winters stresses those mortar joints until they crack and fall out. The tile sections stay largely intact, but the flue leaks gas between them. It’s less the sticky white condensate we find on gas conversions, and more simple fatigue and age. The fix is often a stainless liner dropped down the existing chase, no rebuild. If your oil-fired Elwood home still has its original clay tile liner, it’s past time for a camera scope. Call and we’ll show you exactly what’s in there.
If your chimney has a liner question and you live in Elwood, don’t guess. We’ll scope it, show you the footage, and tell you plainly whether it’s a reline, a rebuild, or something that can wait. Call (631) 318-8656. Wendell picks up.
