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 Long Island
Most chimney liner and rebuild calls on Long Island aren’t about wood-burning fireplaces at all. They’re about oil-burner flues, some of them running through Cape Cods and split-levels built when Eisenhower was in office. The acidic condensate from oil heat eats clay tile liners from the inside, and the salt air off the Atlantic and the Sound eats the masonry from the outside. We see it on Hempstead Turnpike, out in Dix Hills, down in Southampton. If you need Chimney Liner & Rebuild work and you want someone who knows exactly what a 1952 Levittown-model flue looks like when it fails, call Top Hat Chimney at (516) 968-5380.
Why Top Hat Chimney Is Long Island’s Preferred Chimney Liner & Rebuild Company
Wendell Pike has been in more Long Island chimneys than most people have had dinners. He started Top Hat Chimney in 1999, and he still answers the phone himself half the time. That’s not a marketing line. It’s what happens when the company is owner-operated and the owner actually lives in the community he serves.
Long Island customers call us because the national outfits send a stranger with a script. We send the same faces year after year. Wendell and his crew are background-checked, uniformed, and they give you a real arrival window. If that window slips, someone calls you. No call center, no voicemail maze.
Every job gets the 90-Day Done Right Promise in writing. If the liner isn’t installed right or the rebuild doesn’t hold, one call brings the crew back at no charge. Ask anyone on your street how often the big companies do that.
We also put our license number on our trucks and our invoices. Wendell runs into you again on Saturday at the hardware store. That changes how he works on Thursday.
Our Chimney Liner & Rebuild Services in Long Island
Stainless Steel Liner
When a clay tile liner in Long Island is spalled, cracked, or missing sections, a stainless steel liner is usually the answer. We install DuraFlex systems sized correctly for the appliance actually venting through the flue. A lot of Long Island homes upgraded to high-efficiency oil boilers or converted to gas, and the old flue is now too big for the new BTU load. That oversized liner cools the exhaust, condenses acid, and destroys whatever’s left of the tile. A correctly sized stainless liner fixes the draft and stops the cycle.
Flexible Liner
Not every Long Island chimney is straight. Cape Cods and split-levels have offsets, and a rigid liner can’t always snake through. Flexible stainless liners work around the bends without cutting into the masonry. We stock common sizes so a Rockville Centre or Brentwood job doesn’t wait on a backorder.
Liner Replacement
If the old liner is failing, partial patches are usually a waste of money. The camera footage tells the story. We show you exactly what’s cracked, flaking, or missing before we quote a replacement. On Long Island, the decision often comes down to what the home was built with. A 1954 split-level off Sunrise Highway likely has a single-flue masonry chimney sized for one oil burner. If you’ve added a wood stove or converted fuels, that flue may not be legal or safe as-is.
Partial Rebuild
Sometimes only the top three or four courses of brick are gone and the rest of the chimney is solid. Long Island’s coastal moisture makes top-down deterioration common, especially on South Shore barrier islands and North Shore bluffs where salt-laden air works on the mortar. A partial rebuild replaces the damaged section, installs a proper crown, and keeps the rest of the structure intact. We only recommend this when the camera shows the lower flue is still sound.
Full Chimney Rebuild
When the spalling runs deep or the mortar joints are sand, a full rebuild is the honest answer. We rarely recommend it without showing you why. On a Levittown-era home in Nassau County, a full rebuild often means tearing down to the roofline and reconstructing with modern materials sized for today’s appliances, not 1950s oil burners.

Common Chimney Liner & Rebuild Problems We See in Long Island Homes
- Oil-burner flues destroying clay tile from the inside. Long Island has one of the highest concentrations of oil-heated homes in the United States, and the sulfurous, oily condensate attacks clay liners in ways wood creosote never does.
- Oversized flues from boiler upgrades. High-efficiency boilers vent cooler, the flue drafts slower, and the liner stays wet with acid. A 65-year-old flue sized for a 1952 burner is rarely right for a modern one.
- Salt-air spalling on exterior masonry. South Shore and North Shore chimneys face constant marine moisture. Brick faces pop off, mortar erodes, and the crown cracks, letting water into the flue system.
- Wood inserts added to oil-burner flues. That Levittown-era chimney was never designed for wood heat. The double residue, oily soot plus new creosote, creates draft problems and code violations most homeowners don’t know exist.

FAQs - Chimney Liner & Rebuild in Long Island
Because the flue was built for an oil burner, not a fireplace, and oil exhaust is corrosive long after the boiler stops. Acidic condensate settles into the clay tile, spalls the surface, and eventually chunks break away into the smoke chamber. The fireplace never gets used, but the liner still fails. Call (516) 968-5380 for a camera inspection before you guess.
Rarely. The original flue was sized for a specific oil burner BTU load, not for wood combustion temperatures. Wood creosote plus old oily residue creates a double problem: draft failure and a heavier fire risk. Nassau County code often requires a properly sized liner. We check before you burn anything.
Salt-laden ocean air and constant coastal moisture accelerate mortar erosion and brick spalling. The crown is the first part to go because it takes direct weather exposure. Once it cracks, water gets into the flue and the freeze-thaw cycles do the rest. Inland chimneys at the same latitude last longer simply because the air is drier and less corrosive.
Usually not without modification. Gas exhaust is cooler and wetter than oil exhaust, and the old clay tile liner may not meet current sizing or material requirements. A conversion often calls for a smaller stainless liner sized for the new appliance. Some conversions can reuse the existing flue, but only after we verify it with a camera. Don’t take a salesperson’s word for it. Get the footage.
Yes. Every time, no exceptions. The camera footage and a plain-English verdict. If the liner is fine, we’ll tell you it’s fine and leave. Nothing is recommended without evidence you can see yourself. That’s the whole point of the 90-Day Done Right Promise. Call (516) 968-5380 and we’ll set it up.
