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 Dix Hills
Chimney liner and rebuild work in Dix Hills typically runs $2,800 to $7,500 depending on flue count, liner material, and how much masonry needs rebuilding. Most jobs take one to two days once we’re on site, and we schedule around your oil-to-gas conversion timeline when that’s the trigger. Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone himself more often than not. If you’re in Dix Hills and want a straight answer about your flue, call (516) 968-5380.
Most of what we see in Dix Hills follows a pattern: a big colonial or split-level built between the mid-1960s and late 1980s, two or three clay-tile flues in one masonry chase, and a furnace flue that nobody thought about until the oil-to-gas conversion started. The liner problems we find are almost always tied to that history. A generic chimney page won’t tell you that. We will.
Why Top Hat Chimney Is Dix Hills’s Preferred Chimney Liner & Rebuild Company
We’ve worked the Dix Hills area long enough to know the streets off Deer Park Avenue, the colonials along Vanderbilt Parkway, and the split-levels tucked into the Half Hollow Hills school district. That matters when we’re quoting a liner job, because a 1970s center-hall colonial off Carlls Straight Path presents a different chimney than a 1980s ranch near Dix Hills Park. Wendell and his crew show up knowing what they’re looking at, not learning it from the driveway.
The Chimney Liner & Rebuild team carries parts for the major brands this area’s homes actually use: Copperfield, DuraFlex, HeatShield, Gelco. That means less waiting on a shipping truck and more getting the job done before the weather turns. Scheduling is coordinated from our New York City office, but the crews serving Dix Hills are local and the phone is answered by a live person, 24 hours a day, seven days a week. Could be Wendell. Could be a member of his crew. It won’t be a call center.
Ask anyone on your street. That’s the honest truth of how we get most of our work in Dix Hills. A neighbor had a liner done right, at the price they were quoted, and told the next person at the school pickup line. We’ve been at this since 1999, and the 90-Day Done Right Promise is in writing on every single job. If it’s not right, one call brings us back at no additional cost.
Our Chimney Liner & Rebuild Services in Dix Hills
Stainless Steel Liner
For Dix Hills homes converting from oil to gas, a properly sized stainless steel liner is the standard fix for the oversized flue problem. The old oil furnace flue was built for a big, hot, slow draft. A high-efficiency gas unit produces cooler exhaust and a much smaller fire. That flue is suddenly twice as wide as it should be, which means exhaust hangs around, cools, and turns acidic. Condensation eats the old clay tiles from the inside. A DuraFlex stainless liner, sized correctly for the new appliance, solves it. In Dix Hills this runs $2,800 to $5,200 for a single flue, parts and labor included.
Flexible Liner
Flexible liner becomes the practical choice when a Dix Hills chimney has offset flues, which a lot of 1970s split-levels do. The chase doesn’t run perfectly straight, so rigid sections won’t work, and that’s when we spec a flexible stainless system. We measure properly, insulate where code or manufacturer instructions require it, and connect it to the appliance with the correct terminations. No shortcuts masked with mastic. $3,000 to $5,800 is the typical range in Dix Hills for a flexible liner install with proper insulation.
Liner Replacement
If your Dix Hills home still has original clay liners from 1968 or 1974, there’s a good chance those tiles are cracked, spalled, or missing sections entirely. Once a tile section fails, flue gas finds its way into the space between the flue and the masonry. You won’t see it. You won’t usually smell it in the living room. But it’s finding its way into wall cavities, and that’s how a chimney fire becomes a house fire. Replacing a failed clay liner with stainless in a Dix Hills colonial runs $3,200 to $6,500 per flue depending on access.
Partial Rebuild
Partial rebuilds in Dix Hills usually mean the top three to six courses of brick above the roofline, plus a new crown. That’s where Long Island’s salt air does its damage. You’ve got the Sound north of Dix Hills and the Great South Bay to the south, and the marine influence spalls brick faces and corrodes flashing faster than you’d see in, say, Rockville Centre or up-island towns. A partial rebuild with a properly poured crown typically runs $2,400 to $4,800 depending on how much masonry needs cutting out. We’ll show you photos of exactly what came off and why before a single brick gets replaced.

Trusted Brands We Service in Dix Hills
Wendell has worked with DuraFlex, HeatShield, Copperfield, and Gelco systems long enough to know which belongs in which situation, not just which is on the truck. DuraFlex stainless is what we most often recommend for Dix Hills oil-to-gas conversions. HeatShield is a viable middle-ground option when a clay liner is still structurally intact but showing surface cracks. Copperfield caps and terminations hold up to the salt air better than cheap aluminum imitations. The parts we stock are chosen for this local market, and that means faster turnaround when your furnace is already being swapped.
Common Chimney Liner & Rebuild Problems We See in Dix Hills Homes
- Oil-to-gas condensation damage: The single most common liner failure pattern we see in Dix Hills right now. A 1973 colonial converts from oil to high-efficiency gas, the flue is suddenly oversized, condensation sits on those old clay tiles, and within two or three heating seasons the liner is spalled and leaking flue gas. A liner assessment should happen alongside every fuel conversion, not after the furnace is already running.
- Neglected second flue: We can’t count how many Dix Hills homes have two fireplaces, only one of which ever gets used. The other flue sits untouched for years, collecting nesting debris and sticky creosote. On a 1972 colonial off Deer Park Avenue, our crew found the formal-living-room flue packed with second-degree creosote and a family of nesting starlings. The family-room flue had been swept twice in a decade. We relined the neglected flue with stainless, rebuilt the spalling crown, and both fireplaces were safe before the first nor’easter hit.
- Salt-air crown and flashing failure: That persistent marine air between Long Island Sound and the Great South Bay doesn’t care about your chimney’s age. It erodes mortar joints, spalls brick faces, and corrodes galvanized flashing at the roofline. Once water gets into the chimney chase from the top, it accelerates liner deterioration all the way down. We see this more in Dix Hills than in Brentwood or Southampton, where older masonry is already being actively maintained.
- Emergency burning after outages: Nor’easters knock out power in Dix Hills for extended stretches. When the heat goes off, that decorative fireplace you haven’t used in three years suddenly becomes the primary heat source. Burning hard in a flue that hasn’t been inspected is how glazed creosote fires start. Once a year, burn or no burn. Chimneys break in the off-season too.

FAQs - Chimney Liner & Rebuild in Dix Hills
Because your old oil furnace flue is now oversized for a high-efficiency gas unit, and the cooler exhaust it produces creates acidic condensation that eats clay tile liners from the inside out. A 1968 or 1974 Dix Hills colonial was built for a big, hot oil fire. Your new gas burner doesn’t make one. The flue gases cool, condense, and start corroding. A liner assessment during the conversion is the difference between catching this early and finding a spalled, leaking liner two winters later. Call (516) 968-5380 and we’ll schedule a camera inspection before your gas unit goes in. Free estimate, no obligation.
Yes, we can reline just one flue. Each flue in a multi-flue Dix Hills chimney is a separate passage and is treated independently. But here’s the honest part: if one clay liner shows deterioration, its sibling flues are usually not far behind, because they’re the same age and have been exposed to the same salt air and weather. We’ll camera-inspect all of them, show you the footage, and tell you what needs work now versus what can wait. You decide. We’ll never sell you a liner solely because it’s convenient to do both at once.
Spalling on a crown looks like flaking concrete, exposed aggregate you can now see, hairline cracks running in a web pattern, or brick faces that are popping off in thin sheets. Around Dix Hills, the cycles of freeze and thaw from November through March do the damage, and the salt air accelerates it. You should have it addressed before the next freeze cycle, because every time water gets into those cracks and freezes, it expands and widens them. A crown repair or partial rebuild now runs $2,400 to $4,800. Waiting usually turns it into a bigger masonry job, and eventually a full rebuild.
Once a year, burn or no burn. That’s our rule for every Dix Hills home, because a flue that sits unused most of the year can still collect nesting debris, dead animals, and moisture damage from the salt air. Then a nor’easter hits, the power goes out for two days, and you’re burning hard in a flue that hasn’t been checked since 2021. That’s the exact scenario where glazed third-degree creosote fires start. A yearly sweep and inspection costs a fraction of a liner replacement. Call (516) 968-5380 and we’ll set it up.
Because the unused flue is the one that surprises people. It’s not burning off what settles there, so creosote accumulates, birds nest in it, and moisture works on those old tiles year after year with no fire to dry them out. We regularly find second-degree creosote and collapsed nest debris in Dix Hills second flues that haven’t been touched in a decade. When you finally do use that fireplace, whether for resale, a holiday, or a power outage, you’re lighting a fire in a flue you can’t see. A camera inspection tells you exactly what’s in there. Relining it now may be cheaper than relining it after a chimney fire.
If you’re in Dix Hills and you want a straight answer about your chimney liner, call (516) 968-5380. Wendell or a member of his crew will answer. We’ll schedule a time that works, show up when we say we will, and give you the camera footage and a plain-English verdict, every time, no exceptions.
