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.

AfterDuraFlex Fireplace Services in Long Island: What to Know First
We service and repair DuraFlex chimney liners and venting systems all across Long Island, from Levittown ranches to the older colonials out near the North Shore. Most DuraFlex fireplace jobs take one visit, and you’ll know the price before a single tool comes off the truck. If it doesn’t need fixing, we’ll tell you that first.
This page is for Long Island homeowners who have a DuraFlex liner, a fireplace tied to one, or a contractor’s estimate that mentions DuraFlex by name. Wendell Pike and his crew have worked on hundreds of these systems over the years, and we know where they hold up and where they don’t. Call (516) 968-5380 and a live person answers, day or night.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes a solid product, but every liner system has its weak points. Here’s what we actually see on Long Island chimneys, based on the jobs that come across our desk:
- DuraFlex 316L smooth-wall liners and fireplace connector pipe: The smooth-wall liner is great for drafting, but the thin gauge means a hot, fast chimney fire can warp a section. We’ll run a camera down the full length and look for rippling or separation at the seams. If it’s limited to one section, we replace that section. If it’s widespread, we’ll show you the footage and give you an honest replace-or-patch call.
- DuraFlex AL (aluminum) liners on gas fireplaces: These are common on Long Island because they’re affordable and code-compliant for gas. The failure we see is condensation pitting along the lower third of the liner where flue gases cool and turn acidic. That’s a Long Island climate thing, too – humid summers mean more condensate sitting in the liner between burns. A corroded AL liner can’t be patched. It gets replaced, and we’ll talk through whether a step up to a 316L makes sense for your fireplace.
- DuraFlex Pro connection points at the appliance collar: The connector that joins the liner to the fireplace or insert is where we find most installation-related problems. A loose or oversized connector lets flue gas leak into the chase, and that’s how you get soot smell upstairs. We check the collar fit, re-secure it, and seal it properly before we call the job done.
- DuraFlex rain caps and top plates: The cap is your first line of defense against Long Island weather, and a lot of the ones we see on older DuraFlex installations are the factory-original caps that have rusted through. Between the salt air near the South Shore and the freeze-thaw cycles that chew up flashing, a rusted cap lets water straight down onto the liner. We replace caps with stainless steel, and we’ll inspect the top plate seal while we’re up there.
- DuraFlex chimney cover and chase assemblies on prefab fireplaces: When a prefab fireplace with a DuraFlex venting system starts leaking into the firebox, the culprit is usually the chase cover, not the liner itself. We’ve seen covers rust through in fifteen years or less near the coast. We’ll test the firebox, replace the chase cover if needed, and seal it right so the next rainstorm doesn’t end up on your hearth.
Our DuraFlex Fireplace Services Process
Here’s how a typical DuraFlex job goes from the first call to the last sweep of the broom:
- 1
You call, a person answers. It might be Wendell himself. We’ll talk through what you’re seeing, what the fireplace is doing, and whether you need a sweep, a repair, or an inspection.
- 2
We show up when we say we will. Real arrival window, a call if we’re running behind, and a uniformed, background-checked sweep at your door.
- 3
We inspect before we quote. That means a camera down the flue if the problem involves the liner. You’ll see the footage yourself before we recommend anything.
- 4
Upfront price, in writing. The number we quote is the number on the invoice. No surprises at the door. If we find something else mid-job, we stop and show you before we spend a dollar more.
- 5
We make the repair right. For DuraFlex work, that means OEM parts where they matter and quality aftermarket where they don’t. We’ll explain the trade-off in plain English.
- 6
We test, we clean, we’re gone. The fireplace gets fired up or the system gets pressure-checked, the work area gets swept, and every job carries our 90-Day Done Right Promise in writing.
What DuraFlex Fireplace Services Cost in Long Island
Straight numbers, because nobody likes a mystery bill:
- Chimney sweep with camera inspection: $189 to $289 depending on chimney height and condition. This is the starting point for most DuraFlex service calls we get.
- Gas fireplace service and inspection: $149 to $249, which includes checking the DuraFlex venting, the burner, and the log set for proper operation.
- DuraFlex liner section replacement (316L): $400 to $900 per section, installed, depending on access from the roof or the firebox and how much of the existing system has to come apart.
- Full DuraFlex liner replacement (gas, AL to 316L upgrade): $1,800 to $3,400 for a typical one-story Long Island chimney. Two-story homes run higher because of height and access.
- Damper repair or replacement: $175 to $475. A lot of DuraFlex fireplace problems trace back to a damper that never sealed in the first place.
What moves the price is access. If your chimney is a straight shot from the roof on a split-level in Levittown, the labor is quick. If you’ve got a two-story colonial with a steep pitch and a chase that needs scaffold, that’s real time. Every estimate is free and you’ll have it in writing. Call (516) 968-5380 and we’ll give you a number that means something.
Why Long Island Homeowners Call Top Hat Chimney for DuraFlex Work
We’re not a franchise and we don’t operate out of a call center in another state. Wendell Pike started Top Hat Chimney in 1999 and he’s been working Long Island chimneys ever since. His name is on the work and his face is at the hardware store on Saturday. You can find our address and license number on every invoice.
Every job is backed by the 90-Day Done Right Promise. If it’s not right, one call brings us back at no charge. We work on DuraFlex, HeatShield, and Gelco systems, so we’re not tied to one brand and we won’t sell you a product just because we get a better margin on it. Seniors and veterans always get 10% off, and any repair over $200 comes with $40 off. If you’ve got a written estimate from another company, we’ll give you a free second opinion on it. Inside our service county, there’s no trip charge. That’s the whole deal.
FAQs
No, we’re an independent DuraFlex service provider. That means we work on DuraFlex products because they’re durable and common in Long Island homes, not because a manufacturer requires us to push them. We’ll tell you when a DuraFlex part is the right call and when another brand like HeatShield or Gelco makes more sense for your specific fireplace.
It depends on the warranty terms and the age of the liner. Some DuraFlex warranties are pro-rated and only cover manufacturing defects, not corrosion or installation issues. We’ll check the details for you before we touch anything, and we’ll never make a repair that would knowingly void a warranty you still have. Call (516) 968-5380 and we’ll sort it out over the phone.
Most DuraFlex repairs can be scheduled quickly, and many repairs are done in one visit. We don’t promise same-day service because we book real appointments with real arrival windows, but if it’s urgent, call and ask. We’ll tell you honestly whether it’s a rush job or something that can wait a week.
You’ll see the camera footage and we’ll point to the exact section. If it’s pitting or separation in one spot, we patch or replace that section. If the metal is thin across the whole run or there are multiple failed seams, full replacement is usually the honest answer. We’ll show you the evidence and give you the plain-English verdict. If the existing liner still has good metal and your chimney just needs a proper sweep, we’ll tell you that instead and charge you for a sweep, not a liner.
Once a year, burn or no burn. Chimneys break in the off-season too. Long Island humidity works on metal liners even when the fireplace never fires up. A yearly sweep and inspection catches condensed creosote, early rust, and loose connections before they become a four-figure repair. It’s the cheapest insurance your chimney will ever have, and it gives us a baseline for future DuraFlex service calls.
