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
Most chimney liner work in Elwood comes down to one thing: an oil-to-gas conversion that never got finished right. The boiler got swapped in the 1980s or 1990s, the gas company signed off, and the old oversized clay flue stayed in place. For 30 or 40 years that liner has been quietly flaking apart, spilling carbon monoxide into the house, and tripping Suffolk County fire code during point-of-sale inspections. That’s what we fix. Top Hat Chimney has been inside more Elwood chimneys than we can count, and we will tell you plainly whether you need a full liner replacement, a partial rebuild, or nothing at all. Call (631) 502-3612 and we will come take a look.
Why Top Hat Chimney Is Elwood’s Preferred Chimney Liner & Rebuild Company
Wendell Pike started Top Hat Chimney in 1999, and he has run it the same way ever since: put his name on the work, answer the phone, and stand behind what gets installed. That matters in a hamlet like Elwood, where the housing stock runs old and the chimneys run older. We know these streets. We know what a 1960s split-level off Jericho Turnpike looks like on the inside of the flue, and we know what a ranch near Elwood Road does after forty winters of salt air off the Sound.
Every job in Elwood gets the same treatment. Upfront pricing before a single tool comes off the truck. A background-checked, uniformed sweep who gives you a real arrival window and calls if it slips. And a 90-Day Done Right Promise in writing on every invoice. If the liner we install is not right, one call brings Wendell back at no additional cost. That is not a slogan. That is the guarantee stamped on the paperwork.
Our Chimney Liner & Rebuild Services in Elwood
Stainless Steel Liner
A stainless steel liner is the most common service outcome we install in Elwood, and there is a reason for that. The original clay tile liners in these 1950s-1970s tract homes were sized for No. 2 fuel-oil appliances. When homeowners converted to natural gas, the flue stayed oversized, which means the gas appliance cannot draft properly and the clay tiles never heat evenly. We install DuraFlex stainless steel liners sized correctly for the appliance that is actually venting, not the one the house was built around. The difference in draft and safety is immediate.
Flexible Liner
For an Elwood ranch or Cape Cod with an offset flue, a flexible liner often makes the most sense. It snakes through the existing masonry without requiring us to tear out walls or rebuild the chase from scratch. We use Copperfield and DuraFlex flexible systems, and we will show you the camera footage so you can see exactly what was inside before and after. No guesswork, no upsell. Just a plain-English verdict.
Liner Replacement
When the old clay tiles have cracked, spalled, or collapsed, replacement is not optional. This is the single most common finding in Elwood homes of this vintage. A cracked liner cannot be patched responsibly. We cut out or break free the deteriorated clay, remove it, and reline the flue to code. If the surrounding masonry is still sound, this often means you avoid a full rebuild entirely, which can save a homeowner thousands. We will tell you honestly when a replacement is enough and when it is not.
Partial Rebuild
When the crown is cracked, the top courses of brick are spalling, and the flashing has pulled loose, a partial rebuild rebuilds the chimney from the roofline up. We see this constantly in Elwood, because the salt-laden air moving inland from Long Island Sound accelerates efflorescence and spalling on exposed brick. A partial rebuild replaces those deteriorated top courses, pours a new concrete crown with a proper drip edge, and reinstalls flashing. The lower flue can stay untouched if it is sound. It fixes the leak, stops the deterioration, and extends the life of the whole structure.

Trusted Brands We Service in Elwood
We install and service liners from DuraFlex, HeatShield, Copperfield, and Gelco, which means when you call about a chimney liner or rebuild in Elwood, you are not waiting on some special-order part from across the country. We keep what Elwood homes actually need on the truck. DuraFlex stainless liners for oil-to-gas conversions. HeatShield resurfacing systems for cracked clay tile where a full rebuild is not warranted. Copperfield caps and chase covers for those 1980s-90s factory-built fireplaces with rusted tops. If you have an existing system from one of those manufacturers, we can usually match it and repair it same day.
Common Chimney Liner & Rebuild Problems We See in Elwood Homes
- Unlined or oversized oil-to-gas flues. Nearly every inspection call in Elwood uncovers this sooner or later. The original clay liner is sized for a No. 2 fuel-oil appliance, the house has run natural gas for decades, and the flue never got relined. It is a direct Suffolk County Building Code violation and a genuine carbon monoxide risk.
- Spalling brick from salt-laden air. Elwood sits close enough to Long Island Sound that the air carries salt inland. Combined with central Suffolk County freeze-thaw cycles, that salt eats at 50-70-year-old mortar joints. Crowns crack, bricks pop, and water gets into the flue chase.
- Factory-built chases from the 1980s and 1990s. A lot of Elwood’s newer construction and additions used prefabricated fireplace chases rather than full masonry chimneys. Those chases were often built with improper clearance to framing, which means hidden rust, chase leaks, and cap failure. You cannot see it from the ground. You can see it on camera.
- Point-of-sale inspection failures. Elwood real estate moves fast, and Suffolk County fire code inspections are catching old oil flues every month. Homeowners get told at the last minute that the chimney fails inspection and the sale is stalled. We handle those calls regularly, and we can usually turn a reline around within days, not weeks.

FAQs - Chimney Liner & Rebuild in Elwood
Does Elwood’s requirement to reline an old oil flue after switching to gas apply to all homes?
Yes. Suffolk County fire code requires that a flue be sized and lined for the appliance actually venting through it. If your house was built with an oil-fired boiler and you switched to natural gas, the old clay liner is technically oversized and code-deficient unless it was properly relined at the time of conversion. Most Elwood homes we inspect were never relined. Call (631) 502-3612 and we will confirm yours with a camera.
Why does my newer Elwood home with a factory-built fireplace need a chimney liner inspection?
Factory-built fireplaces from the 1980s and 1990s have their own liner systems and chases, and they fail in ways masonry chimneys do not. Improper clearance to framing, hidden chase rust, and deteriorating caps are common in Elwood. The liner inside a prefabricated unit also degrades with use, and you cannot see it from the living room. A camera inspection answers the question in forty minutes.
Can a HeatShield system fix my cracked clay tile liner without a full rebuild?
In many cases, yes. HeatShield is a ceramic resurfacing system that seals and smooths cracked clay tile liners from the inside without requiring us to tear out masonry or do a full rebuild. It is appropriate when the clay tiles are cracked but the surrounding chimney structure is still sound. If the flue has collapsed or multiple tiles have shifted, a stainless liner is the safer call. We use both systems and will show you the footage before recommending either.
What causes the white staining and flaking brick I see on my Elwood chimney?
That is efflorescence and spalling, and in Elwood it is driven by two things: salt-laden air off Long Island Sound and decades of freeze-thaw cycling. Moisture gets into the brick, salt crystallizes inside the pores, and the face of the brick pops off. White staining is cosmetic at first. Spalling is structural, because once the brick face is gone the inner brick is exposed and the deterioration accelerates. A partial rebuild with a proper crown and flashing usually stops it.
Does a partial rebuild on a 1960s Elwood ranch fix the draft problem too?
Not always, and that is the honest answer. A partial rebuild fixes the structure above the roofline: crown, top courses, flashing. If the draft problem is caused by an oversized flue from an oil-to-gas conversion, the rebuild will not fix it. That requires relining the flue to match the appliance. Sometimes Elwood homeowners need both. We will camera the flue and tell you exactly what is structural and what is draft-related before any work gets booked.
