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 Chimney Cleaning & Sweep in Commack: What to Know First
We clean and sweep DuraFlex chimney systems in Commack for $215 to $375 on most single-flue homes. That covers a full creosote and soot removal, a Level 1 inspection, and camera footage of your flue before and after. We’re an independent DuraFlex service provider, not a factory arm, so we tell you plainly when a cleaning is all you need and when something underneath is starting to go. If you own a home in Commack with a DuraFlex liner and can’t remember the last time it was swept, call Wendell at (631) 502-3612 and he’ll give you an upfront number before any tools come off the truck.
Key Takeaways
- DuraFlex liners are solid products, but they collect creosote differently than rigid flues and need a sweep who knows the difference.
- Most DuraFlex cleaning jobs in Commack run $215 to $375, with the higher end reserved for heavy third-degree creosote or two-story liners.
- We are independent. If your DuraFlex system is under warranty, we work in a way that keeps it that way.
- Every job includes camera footage. You see what we see, no exceptions.
How DuraFlex Products Fail - and How We Fix Them
DuraFlex builds a good liner. We’ve installed enough of them to know where they hold up and where they don’t. Most failures we see in Commack aren’t manufacturing defects. They’re what happens when a flexible liner gets years of heat, moisture, and Long Island temperature swings.
- DuraFlex 316L liners with pitting at the seam. This shows up most often on oil-to-gas conversions or wood stoves burning wet wood. The 316L alloy handles condensation better than aluminum, but acidic condensate still pools at the seam line and slowly eats at it. We find it with the camera, not the brush. Fix is a gentle sweep, a seam inspection, and an honest talk about whether the liner has five years left or two.
- DuraFlex Pro with creosote glaze in the corrugations. The ribbed walls of flexible liners grab creosote where a smooth rigid flue would shed it. After a few seasons of low fires or unseasoned wood, you get a hard glaze in the valleys between ribs. A standard brush spins right over it. We use a rotary whip head and then camera the flue to make sure the glaze is gone, not just polished.
- DuraFlex liner kinked or ovaled during installation. We see this a lot when a previous installer forced the liner through a tight smoke shelf or an offset flue. You get a restriction that slows draft, backs smoke into the house on windy days, and builds creosote above the kink. It’s not a cleaning problem alone. We’ll show you the kink on camera and tell you straight whether a re-pull or a patch is the honest fix.
- DuraFlex rain cap and termination ring rot. The liner itself might be fine, but the cap assembly up top is the first thing to go. The termination ring rusts at the fasteners, the cap screen clogs with airborne soot, and suddenly you’ve got rain in the flue and sluggish draft. We replace caps and rings as a matter of course on any sweep where they’re failing.
- DuraFlex two-ply liners separating at the inner wall. This is rare but it happens on older installations where the liner was sized wrong and run too hot. The inner ply delaminates and you get a flap inside the flue. A brush will hang on it. We catch it on the camera, and the fix is a liner replacement, not a cleaning. Wendell will be the first one to tell you.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call and get a real price. You reach Wendell or a live person at (631) 502-3612, day or night. We ask a few questions: what’s burning, when’s the last sweep, one story or two. Then we give you the number.
- 2
Arrival with a window. You get a real arrival window, and if it slips, we call. No mystery hours and no waiting around half the day.
- 3
Drop cloths and the first look. We lay protection around the fireplace or stove and run a visual on what’s coming out. Then we sweep, starting at the top or bottom depending on your setup.
- 4
Camera inspection. Before we call the job done, the camera goes down the flue. You watch the footage with us. Creosote left behind, a seam opening up, a cap rusted through, you see it on the screen.
- 5
Plain-English verdict. If the flue is clean and healthy, we say so. If something needs attention now, we give you a written number. If it can wait a year, we tell you that too. We’re not here to sell work that doesn’t need doing.
- 6
Cleanup and the promise. We leave the hearth cleaner than we found it and hand you a job sheet with the 90-Day Done Right Promise on it. If something isn’t right, one call brings us back.
What DuraFlex Chimney Cleaning & Sweep Costs in Commack
Here’s what we actually charge, no bait-and-switch.
- Standard sweep and Level 1 inspection, one flue: $215 to $285
- Heavy creosote or two-story liner: $300 to $375

What moves the price is the amount of creosote, the liner height, and whether we need a rotary whip instead of a standard brush. We never quote one number and show up with another. The price Wendell gives you on the phone is the price on the invoice. Call (631) 502-3612 for a free estimate on your exact setup.
Why Commack Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been working in Commack since our founding in 1999, including plenty of homes in Burr Farms. Wendell Pike started this company and still answers the phone on plenty of nights. When you call, you reach a live person, not a call center routing you to a stranger.
We work with DuraFlex as an independent service provider, and we also service HeatShield and Gelco systems when a home has a mixed setup. That means you’re not stuck calling three companies because the previous owner used two different brands. We look at the whole chimney, not just one brand’s box.
Every job, including a simple sweep, gets the camera. You see the footage before you pay. Every job carries the 90-Day Done Right Promise in writing. And every job gets upfront pricing. Ask anyone on your street.
FAQs
No. A professional sweep using the correct equipment for a flexible liner does not void a DuraFlex warranty. What voids a warranty is a harsh chemical treatment or an abrasive tool that scores the inner wall. We use brushes and heads sized for flexible liners and we document the sweep with camera footage, which also gives you a record if you ever need to file a warranty claim.
Once a year, burn or no burn. That’s the rule for any wood-burning system, and flexible liners like DuraFlex collect creosote in the corrugations slightly faster than smooth rigid flues. If you burn wet wood or run low, slow fires, you may need two visits a year. If the system hasn’t been burned in a while, condensation can still work on the liner. Call (631) 502-3612 and we’ll talk about your burn habits and what’s realistic.
Yes. The camera footage tells the story. Pitting at the seam, delamination between plies, a kink that’s restricting draft, or rust through the cap assembly are all visible. We’ll show you the images and give you a straight answer. Sometimes the answer is a cleaning and five more years. Sometimes it isn’t. We do not recommend replacement unless the camera evidence supports it, and we’ll show you that evidence before you spend a dime. Call (631) 502-3612 to schedule an inspection.
We keep common DuraFlex components on the truck and in local stock: rain caps, termination rings, top plates, and connector sections. For less common DuraFlex Pro or two-ply parts, we order direct and typically have them within a few days in Commack. If your liner is under warranty, we’ll tell you whether the part should come through a warranty claim and walk you through that process. It costs you nothing to find out.
First-degree creosote becomes second-degree, which becomes a glaze that a standard brush won’t remove. Once it hardens in the ribbed walls of a DuraFlex liner, it’s slower to clean and more expensive. Worse, creosote is fuel. A chimney fire doesn’t announce itself. This is not a scare pitch. It’s what the inside of a flue looks like after one skipped season, and we have the footage. Once a year, burn or no burn. Call (631) 502-3612 and get on the schedule before burning season.
Wendell Pike and our crew have swept DuraFlex systems in Commack for decades. We’re not a franchise and we’re not a call center. We answer the phone, we show up, we do the work, and we stand behind it in writing. Call (631) 502-3612 for a free estimate on your DuraFlex chimney cleaning and sweep.
